EXECUTIVE
SUMMARY
This
is
a
revision
of
the
original
Occupational
and
Residential
Exposure
Assessment
and
Recommendations
Document
for
pentachloronitrobenzene
(
PCNB),
(
S.
Tadayon
August31,
2003).
This
chapter
has
been
revised
to
address
comments
made
by
the
registrants.

This
document
contains
the
occupational
and
residential
exposure
assessment
for
various
uses
of
pentachloronitrobenzene
(
PCNB).
The
document
also
considers
potential
risk
mitigation
measures
such
as
personal
protective
equipment
(
PPE)
and
engineering
controls
for
handlers
and
proposed
restricted
entry
intervals
(
REIs)
for
postapplication
activities.
The
scope
of
the
document
covers
all
registered
PCNB
uses.

PCNB,
is
an
organochlorine
fungicide
used
for
seed
and
soil
treatments
at
planting.
Registered
use
sites
include,
beans,
brassica
crops,
cotton,
garlic,
hot
pepper,
peanut,
pepper,
potato,
tomatoes,
seed
treatment,
ornamental
plants,
cut
flowers,
dormant
roses
and
bulbs,
magnolia
tree,
southern
pine
seedlings
and
turf.

Application
techniques
identified
to
apply
PCNB
are:
fixed
­
wing­
aircraft
(
potato
only),
tractor­
drawn
equipment,
dip
tank,
drencher,
drill
box,
drip
irrigation,
duster,
hand
held
sprayer,
hose­
end
sprayer,
liquid
seed
treater,
mechanical
sprayer;
mist
sprayer,
overhead
sprinkler
irrigation,
planter/
seed
box;
seed
treater,
slurry­
type
seed
treater,
and
hand
held
equipment.
PCNB
is
formulated
as
manufacturing
products,
emulsifiable
concentrate
liquids,
dusts/
powders,
water
dispersible
granules,
flowable
concentrate,
ready
to
use
liquid
and
wettable
powders.
The
application
rates
used
in
the
assessment
are
intended
to
reflect
the
upper
range
of
rates
on
the
labels.
Examples
of
the
application
rates
used
in
this
assessment
include,
but
are
not
limited
to
the
following:
for
agricultural
uses
the
maximum
rates
for
brassica
crops
is
30.0
lb
ai/
acre,
potato
rate
is
25.0
lb
ai/
acre,
cotton
is
2.0
lb
ai/
acre
pepper
and
tomato
rates
are
7.5
lb
ai/
acre,
outdoor
ornamental
rate
is
0.015
lb
ai/
gallon
and
turf
is
43.6
lb
ai/
acre.

The
Hazard
Identification
Assessment
Review
Committee
(
HIARC)
selected
the
following
endpoints
for
exposure
risk
assessment:
short­
and
intermediate­
term
dermal
NOAEL
is
300
mg/
kg/
day
short­
and
intermediate­
term
inhalation
NOAEL
is
1
mg/
kg/
day.
based
on
liver
and
thyroid
lesions
seen
in
rats.
An
uncertainty
factor
or
"
target"
margin
of
exposure
(
MOE)
of
100
is
based
on
10x
for
differences
among
humans
(
intra
species
variability)
and
10x
for
differences
between
the
test
animals
and
humans
(
inter
species
extrapolation).
Thus
MOEs
of
greater
than
100
do
not
exceed
the
Agency's
level
of
concern
for
occupational
uses.
The
residential
use
includes
a
10x
FQPA
safety
factor
and
the
or
target
MOE
is
1000.

HED's
Carcinogenicity
Peer
Review
Committee
(
CARC)
classified
PCNB
as
a
Group
C
­
possible
human
carcinogen
but
not
sufficient
human
carcinogenic
potential,
and
therefore,
the
quantification
of
human
cancer
risk
was
not
recommended
For
agricultural
uses,
HED
relied
almost
completely
on
surrogate
data
from
the
Pesticide
Handlers
Exposure
Database
(
PHED)
Version
1.1.
For
residential
handler
HED
used
the
ORETF
4
study
data
and
the
Residential
SOPs.

The
results
of
the
short­
and
intermediate­
term
seed
handler
assessments
indicate
that
for
all
formulation
the
majority
of
the
potential
exposure
scenarios
provide
total
MOE(
s)
greater
than
or
equal
to
100
at
the
clothing
attire
of
long
pants,
long
sleeved
shirts,
gloves,
and
no
respirator
while
using
open
systems.
Seed
handlers
working
in
a
smaller
facility
performing
multiple
activities
might
require
respirator
in
order
to
have
MOEs
of
greater
than
or
equal
to100.
There
is
no
separate
measurement
of
exposure
for
various
job
function
performed
by
seed
handlers
in
a
smaller
facility,
therefore
it
is
not
feasible
to
require
respirator
for
workers
treating
seeds
in
a
small
operation
to
wear
respirator
as
soon
as
they
enter
in
to
the
facility.

The
agricultural
results
of
the
short­
and
intermediate­
term
occupational
handler
assessments
indicate
that
for
the
dry
flowable
formulation
the
majority
of
the
potential
exposure
scenarios
provide
total
MOE(
s)
greater
than
or
equal
to
100
at
the
baseline
clothing.
For
the
liquid
formulation,
the
risks
indicate
that
in
order
for
the
mixer/
loaders
to
achieve
MOEs
of
100
for
all
uses,
the
addition
of
chemical
resistant
gloves
and
dust
mist
respirator
is
required
For
the
wettable
powder
formulation
risks
indicate
that
in
order
for
the
mixer/
loaders
to
achieve
MOEs
of
100
some
uses
should
be
packaged
in
water
soluble
packets.
The
risk
for
the
majority
of
uses
with
wettable
powder
is
acceptable.

Chemical
specific
post­
application
exposure
data
have
not
been
submitted
by
the
registrant
in
support
of
reregistration
of
PCNB.
However
there
is
a
low
potential
for
occupational
postapplication
exposure
when
a
pre­
plant
or
at
planting
fungicide
is
used.
Many
agricultural
operations
mechanically
plant
seeds
early
in
the
season,
which
minimizes
the
potential
for
contact.
Significant
exposure
during
harvesting
or
any
other
late
season
activities,
is
not
likely
since
the
chemical
is
applied
pre­
plant
or
at
planting.
However
the
Agency
has
determined
that
there
are
potential
postapplication
exposures
to
individuals
re­
entering
PCNB
treated
areas
for
the
purpose
of
mowing
(
roadsides,
rights­
of­
way,
golf
course)
and
harvesting
(
sod
farms).

The
short­
and
intermediate­
term
risks
to
golf
course
workers
or
sod
growers
doing
hand
harvesting,
transplanting,
and
hand
weeding
tasks
does
not
exceed
the
level
of
concern
on
the
day
zero
at
the
rate
of
32.67
lbs
ai/
acre
or
43.56
lbs
ai/
acre.

In
residential
settings,
the
Agency
does
not
use
personal
protective
equipment
to
limit
exposures,
because
they
are
viewed
as
impractical
and
not
enforceable.
Risk
estimates
are
based
on
handlers
wearing
short­
sleeve
shirts,
short
pants,
shoes,
and
socks.
Residential
risks
are
of
concern
for
a
few
scenarios,
(
i.
e.,
MOE
<
1000)
for
risk
assessments.
The
scenarios
where
MOEs
do
not
meet
the
Agency's
target
MOE
include
dermal
and
inhalation
risk
for
mixing/
loading/
applying
liquid
with
low
pressure
handwand
and
dermal
and
inhalation
risk
for
garden
hose­
end
sprayer
and
belly
grinder.

Postapplication
residential
risk
estimates
on
the
day
of
application
are
the
key
concern
The
Agency
considered
a
number
of
residential
postapplication
dermal
exposure
scenarios
5
including
toddlers,
youth­
aged
children,
and
adults.
A
postapplication
oral
risk
assessment
for
incidental
ingestion
by
toddlers
was
also
conducted,
considering
an
oral
endpoint
of
1
mg/
kg/
day.
All
assessed
postapplication
exposures
to
toddlers
did
not
have
MOEs
greater
than
or
equal
to
1000.

EPA
assessed
postapplication
risks
to
toddlers
from
incidental
oral
ingestion
using
a
shortterm
and
intermediate­
term
incidental
oral
endpoint
(
1
mg/
kg/
day)
The
results
indicate
that
risks
from
short­
term
and
intermediate­
term
exposures
were
a
concern
(
i.
e.,
MOE
<
1000)
for
toddlers.

Overall
Risk
Summary
This
risk
assessment
applied
the
latest
exposure
data,
toxicology
information,
and
use
data.
The
overall
results
indicate
that
the
Agency
has
risk
concerns
for
some
PCNB
use­
patterns
involving
agricultural
crops.
Residential
handler
and
postapplication
risks
are
of
concern
for
some
use­
patterns
and
no
practical
risk
mitigation
measures
are
available
to
the
Agency
to
reduce
these
risks.

BACKGROUND
Purpose
In
this
document,
which
is
for
use
in
EPA's
development
of
the
PCNB
Reregistration
Eligibility
Decision
Document
(
RED),
EPA
presents
the
results
of
its
review
of
the
potential
human
health
effects
of
occupational
and
residential
exposure
to
PCNB.

Criteria
for
Conducting
Exposure
Assessments
An
occupational
and/
or
residential
exposure
assessment
is
required
for
an
active
ingredient
if
(
1)
certain
toxicological
criteria
are
triggered
and
(
2)
there
is
potential
exposure
to
handlers
(
mixers,
loaders,
applicators,
etc.)
during
use
or
to
persons
entering
treated
sites
after
application
is
complete.
For
PCNB,
both
criteria
are
met.

Incident
reports
According
to
the
Recognition
and
Management
of
Pesticide
Poisoning,
5
th
edition,
symptoms
of
prolonged
exposure
to
PCNB
can
include:
skin
sensitization
and
irritation,
conjunctivitis
and
keratitis
following
eye
contamination.
Systemic
poisoning
has
not
been
reported.
Clearance
is
chiefly
via
the
liver
and
biliary
excretion.
For
the
reporting
period
1993­
1998,
there
were
41
cases
reported
in
the
AAPCC
surveillance
systems.
There
were
21
symptomatic
cases,
including
6
ranked
moderate.
Of
the
41
cases,
15
were
seen
in
a
health
care
facility,
and
1
was
hospitalized.

From
1982­
1997,
there
are
a
total
of
thirty
PCNB

Many
of
these
include

SEED
TREATMENT
USES
There
are
a
number
of
methods
that
can
be
used
to
treat
seeds
both
commercially
and
onfarm
On­
farm
seed
treatment
methods
include
concrete
tumbler,
drill
box,
duster,
in­
furrow,
mist­
type
seed
treater,
planter/
seed
box,
seed
treater
and
slurry­
type
seed
treater.
Commercial
seed
treatment
equipment
produced
by
Gustafson
include
computerized
seed
and
chemical
Proportioner,
Gustafson
Accu­
Treat
Treater,
Gustafson
S­
Series
and
SS­
Series,
Gustafson
SSAMP
Treater,
and
Triple
Treat
Seed
Treater.

On­
farm
seed
treatment
is
considered,
by
most
sources,
to
represent
a
relatively
small
proportion
of
the
total
use
of
treated
seed
in
the
U.
S.
This
may
be
due,
in
large
part,
to
the
greater
time
investment,
labor
and
equipment
commitment
required
for
on­
farm
seed
treatment
compared
to
buying
the
treated.
However,
some
seed
crops
record
a
sizable
percentage
of
onfarm
seed
treatment.
A
risk
assessment
for
on­
farm
seed
treatment
(
planter
box)
is
completed
in
this
document
using
a
dust
formulation
study.
The
dust
formulation
study
is
the
only
on­
farm
seed
treatment
study
available,
and
is
used
as
a
surrogate
for
planter
box
seed
treatment
with
liquid
formulation.
The
planter
box
seed
treatment
with
liquid
formulation
risk
assessment
for
liquid
is
considered
conservative
since
treatment
with
dust
formulations
usually
present
a
higher
risks
than
liquids.
There
are
no
data
for
other
seed
treatments
done
on­
farm.

There
is
a
significant
exposure
to
the
workers
planting
treated
seed.
An
Exposure
assessment
is
presented
for
workers
loading
treated
seed
into
plant
hoppers
and
driving
a
closed
cab
tractor
to
pull
the
planter
around
the
field.

Exposure

This
database
was
created
by
U.
S.
EPA,
and
measures
exposure

for
seed
treaters
and
planters
under
actual
field
conditions.

Commercial
Seed
Treatment
For
commercial
assessment
four
standard
scenarios
were
assessed.

1)
Loader/
Applicator
The
loading/
applying
of
all
formulation
(
except
liquid
closed
system
and
wettable
powder)
is
comprised
of
3
exposure
studies
(
MRID
#
43080049,
42251902,
44731501).
The
loader/
applicator
activities
in
these
3
exposure
studies
encompass
a
wide
range
of
seed
treater,
amount
of
seed
and
amounts
of
pesticides
handled
for
seed
treatment
scenarios.

The
three
studies
in
this
scenario
monitored
an
open
loading/
applying
activity
for
various
15
seed
treatment
facilities.
There
are
an
average
of
9
replicates
per
study
(
ranging
from
1
to
20
replicates
per
study).
Two
of
the
three
studies
monitored
dermal
exposures
with
patch
dosimetry
for
hand
rinses
and
face
wipes.
The
methodology
in
the
third
study
was
whole
body
dosimetry,
hand
rinses
and
face
wipes.

In
the
study
with
MRID
#
430800­
49,
20
replicates
were
monitored.
Each
replicate
was
a
minimum
of
3.5
hours.
This
study
involved
the
treating
of
soybean
seed
with
Apron
using
a
Gustafson
seed
treaters
at
two
facilities
in
the
Midwest.
The
chemical
was
manually
added
to
the
mix
tanks
from
1
gallon
jugs
(
15
replicates)
or
3
lb
water
soluble
bags
(
5
replicates).
12500
lbs
of
seed
were
treated
per
hour.
Dermal
exposure
was
measured
using
whole
body
dosimeters,
handwashes
and
face
wipes.
Inhalation
exposures
were
measured
with
glass
fiber
filters
and
XAD
tubes.
Field
recovery
was
grade
A
for
the
handwashes
and
air
filters
and
grade
AB
for
the
face
wipe
and
whole
body
dosimeters.

In
the
study
with
MRID
#
422519­
02,
6
replicates
were
monitored.
The
average
duration
of
each
replicate
was
7.4
hours.
This
study
involved
the
treating
of
canola
with
Oftanol
technical
at
one
facility
in
Canada
with
a
150
kg
batch
blending
machine.
The
chemical
was
pumped
to
the
mixing
tank
from
a
55
GA
drum.
Each
batch
took
five
minutes.
Dermal
exposure
was
measured
using
patches
and
handwash.
Inhalation
exposures
were
measured
using
quartz
microfiber
filters.
Field
fortification
recovery
was
grade
A
for
all
media.

In
the
study
with
MRID
#
447315­
01,
2
replicates
were
monitored
(
only
1
replicate
was
included
in
the
data
base
due
to
inadequate
lab
recovery).
This
study
involved
the
treating
of
canola
with
Vivavax
RS
flowable
at
one
facility
in
Canada
with
a
Gustafson
Accu­
treat
film
coater.
The
chemical
was
transferred
to
the
mixing
tank
from
a
tote.
Dermal
exposure
was
measured
using
patches,
handwashes,
glove
washes
and
face
washes.
Inhalation
exposures
were
measured
with
glass
fiber
filters
and
XAD
tubes.
Field
fortification
recovery
was
grade
AB
for
dermal
media.
The
field
recovery
for
the
inhalation
media
was
220
percent.
The
laboratory
recovery
was
grade
A
for
both
the
dermal
and
inhalation
all
media.

2)
Bagger
The
bagging
system
for
all
formulation
(
except
liquid
closed
system
and
wettable
powder)
is
comprised
of
3
exposure
studies
(
MRID
#
43080049,
42251902,
and
44731501)
for
the
dermal
and
inhalation.
The
bagging
in
these
studies
encompass
a
wide
range
of
bagging
equipment,
amount
of
seed
and
amounts
of
pesticides
handled
for
seed
treatment
scenarios.

The
three
studies
in
this
scenario
monitored
bagging
treated
seed
in
various
seed
treatment
facilities.
The
number
of
replicate
ranges
from
1
to
20
per
study.
Two
of
the
three
studies
monitored
dermal
exposures
with
whole
body
dosimeter,
face
and
neck
and
hand
rinses.
The
methodology
in
the
other
three
studies
was
dermal
patches
and
hand
rinses.

In
the
study
with
MRID
#
430800­
49,
20
replicates
were
monitored
The
same
bagging
method
was
used
at
both
facilities.
The
bagger
clamped
an
empty
bag
to
the
bagging
machine
and
16
the
treated
seed
dropped
into
the
bag.
The
seed
flow
stopped
automatically
and
the
filled
bag
dropped
onto
a
conveyor
belt.

In
the
study
with
MRID
#
422519­
02,
3
replicates
were
monitored
The
treated
seed
was
transferred
to
a
bagging
hopper
after
passing
through
a
compactor
and
shaker
screen.
The
bagger
attached
a
bag
to
the
hopper
and
filled
the
bag.
The
bagger
then
removed
the
bag,
carried
it
to
a
sewing
station
and
sewed
it
with
a
hand
held
sewer.

3)
Sewers
The
sewing
system
for
seed
treated
with
all
formulation
(
except
liquid
closed
system
and
wettable
powder)
is
comprised
of
2
exposure
studies
(
MRID
#
430800­
49,
and
447315­
01)
for
the
dermal
and
inhalation.

The
two
studies
in
this
scenario
monitored
sewing
various
bags
of
treated
seed
in
a
number
of
seed
treatment
facilities.
The
number
of
replicate
ranges
from
1
to
20
per
study.
All
of
the
studies
monitored
dermal
exposures
with
whole
body
dosimeter,
face
and
neck
and
hand
rinses.

In
the
study
with
MRID#
430800­
49,
20
replicates
were
monitored.
The
same
sewing
method
was
used
at
both
facilities.
The
sewer
grabbed
the
bag,
attached
ID
tags
and
guided
it
through
the
sewing
and
stamping
machines.

In
the
study
with
the
MRID
#
447315­
01
one
replicate
was
monitored.
This
replicate
was

4)
Multiple
Activities
(
e.
g.,
loader/
applicator,
bagger,
sewer,
cleaner,
calibrator,
repair,
forklift
driver,
etc).

In
the
smaller,
less
automated
facilities,
one
worker
will
often
have
multiple
duties
within
the
plant.
Therefore,
seed
treatment
SOP
contains
a
scenario
labeled
"
Multiple
Activities"
in
order
to
address
this
aspect
of
small
commercial
operations.

The
multiple
activities
for
all
formulation
(
except
liquid
closed
system
and
wettable
powder)
is
comprised
of
4
exposure
studies
(

for
the
dermal
and
inhalation.
The
multiple
activities
in
these
studies
encompass
a
wide
range
of
seed

amount
of
seed
and
amounts
of
pesticides
handled
for

The
4
studies
in
this
scenario
monitored
multiple
activities
for
various
seed
treatment
facilities.
The
number
of
replicates
ranges
from
3
to
45per
study).
Three
of
the
four
studies
monitored
dermal
exposures
with
whole
body
dosimeter,
face
and
neck
and
hand
rinses.
The
methodology
in
the
other
study
was
dermal
patches
and
hand
rinses.

In
the
study
with
MRID
#
454427­
01,
20
replicates
were
monitored.
This
study
involved
the
treating
of
rice
at
three
sites
in
the
south
with
ICON
6.2
FS
aqueous
flowable
using
Gustafson
PSD50­
D3
treaters.
A
total
of
45
workers
were
monitored
with
an
average
replicate
time
of
6.3
hours.
These
worker
performed
mixing/
loading,
bagging
and
clean­
up.
The
product
was
added
to
the
mix
tanks
from
a
30
gallon
containers.
The
rice
seed
was
dumped
through
the
seed
treater
and
stored
in
a
bin
until
bagged.
Dermal
exposure
was
measured
with
whole
body
dosimeters,
handwash
and
face/
neck
wipes.
Inhalation
exposures
were
measured
with
37
mm
filters
and
adsorption
tubes.
Dermal
field
recoveries
were
grade
AB.
Inhalation
recoveries
were
grade
A.

In
the
study
with
MRID
#
422519­
02,
3
replicates
were
monitored.
The
shift
foreman
supervised
the
process
and
assisted
with
various
tasks
as
necessary.

In
the
study
with
the
MRID
#
MRID
449045­
26,
12
replicates
were
monitored
This
study
involved
the
treating
of
wheat,
barley,
oats
and
peas
at
two
sites
in
Canada
using
Vitaflow
280
packaged
in
1000
liter
totes
or
Vivavax
Single
packaged
in
a
200
liter
drums.
The
replicates
were
one
half
day
in
length
and
involved
a
total
of
5
workers.
Workers
loaded
the
formulation
into
the
seed
treater,
operated
the
seed
treater,
bagged
treated
seed,
transferred
treated
seed
to
storage
bins
or
trucks,
cleaned
up
the
seed
treatment
area
and
cleaned
up
treated
seed
storage
bins
or
the
bagging
area.
Dermal
exposure
was
measured
with
whole
body
dosimeters
and
cotton
gloves.
Inhalation
exposures
were
measured
with
millipore
filters.
The
dermal
field
fortification
samples
had
highly
variable
recoveries
possibly
due
to
contamination.

In
the
study
with
MRID
447315­
01,
6
replicates
were
monitored.
2
replicates
stacked
bags,
3
replicates
did
all
tasks
and
1
replicate
did
all
tasks
except
loading.

On­
Farm
Seed
Treatment
The
on­
farm
system
for
dust
formulation
subset
is
comprised
of
1
exposure
study
(
MRID
#
44031611)
for
the
dermal
and
inhalation.

In
this
study
four
workers
(
twelve
replicates)
mixed
and
applied
dust
formulations
to
winter
wheat
in
grain
drills
at
an
application
rate
of
2
oz.
per
120
lbs.
of
seed.
Each
replicate
lasted
between
19
and
33
minutes
and
each
worker
handled
22.5
ounces
of
active
ingredient
per
work
period.
Workers
loaded
seed
drill
hoppers
with
wheat
seed
and
a
lindane/
maneb
dust
formulation.
Dermal
exposures
were
measured
with
patches
and
handwash.
Inhalation
exposures
were
measured
with
glass
fiber
filters.
The
field
recovery
was
grade
A
for
all
media.
18
Planters
The
planters
system
for
all
treated
seed
is
comprised
of
2
exposure
studies
(
MRID
#
42251901,
45654503)
for
dermal
and
inhalation.

In
the
study
with
the
MRID
#
456545­
03,
13
replicates
were
monitored.
Workers
involved
in
the
loading
and
drilling
of
seed
treated
with
Baytan.
The
replicates
were
all
located
at
different
sites
in
the
UK.
The
seed
was
loaded
into
the
drill
hoppers
from
0.5
or
1
ton
supersacks
or
50
kg
bags.
The
amount
of
seed
handled
ranged
from
1100
to
12,100
lbs
and
the
amount
of
ai
handled
ranged
from
0.35
to
4.72
lbs.
The
loading
time
ranged
from
19
to
83
minutes
while
the
planting
time
ranged
from
155
to
487
minutes.
The
seed
planting
rate
per
acre
was
not
given
in
the
review.
The
same
worker
performed
both
the
loading
and
planting.
Dermal
exposure
was
measured
with
inner
and
outer
whole
body
dosimeters
which
included
a
cap,
a
jacket
and
trousers
over
a
long
sleeve
T­
shirt
and
long
johns
and
two
sets
of
cotton
gloves.
The
gloves
were
changed
at
the
end
of
loading.
Inhalation
exposures
were
measured
with
37
mm
glass
fiber
filters
and
the
filters
were
changed
after
loading.
The
dermal
results
were
adjusted
by
a
clothing
protection
factor
to
account
for
the
fact
that
5%
of
the
outer
residues
was
found
on
the
inner
dosimeters.
Dermal
and
inhalation
field
recoveries
were
grade
A.

In
the
study
with
the
MRID
#
422519­
01,
13
replicates
were
monitored.
Workers
involved
in
the
loading
and
drilling
of
canola
seed
treated
with
Oftanol
which
forms
a
hard
shell
coating.
The
replicates
were
located
at
one
site
in
Manitoba
using
four
different
planting
rigs.
Four
workers
participated
in
the
study
and
the
replicates
averaged
3.2
hours
in
duration.
The
seed
was
loaded
into
the
drill
hoppers
from
25
kg
bags.
The
amount
of
seed
handled
per
replicate
averaged
360
pounds
and
the
amount
of
ai
handled
averaged
4.33
lbs.
The
seed
was
planted
at
a
rate
of
6
to
8
pounds
per
acre.
The
same
worker
performed
both
the
loading
and
planting.
Dermal
exposure
was
measured
with
patches
located
both
inside
and
outside
the
worker's
coverall.
Hand
exposures
were
measured
by
handrinse.
Inhalation
exposures
were
measured
with
37
mm
quartz
microfiber
filters.
Dermal
and
inhalation
field
recoveries
were
grade
A.

2.1
Occupational
Seed
Handler
Exposures
There
are
potential
exposures
to
loader/
applicator,
baggers,
sewers,
workers
performing
multiple
activities,
on­
farm
treatment
with
planter
box
and
seed
planters
during
usual
use­
patterns
associated
with
PCNB.
Based
on
the
use
patterns
and
potential
exposures
described
above,
6
exposure
scenarios
are
identified
to
represent
the
extent
of
PCNB
seed
treatment
uses.

The
potential
seed
treatment
handler
exposures
to
6
exposure
scenarios
are
assessed
in
this
RED
chapter
using
the
toxicological
endpoints
and
uncertainty
factors
associated
with
the
active
ingredient.

2.1.1
Summary
of
Uncertainties
The
seed
handler
exposure
assessments
encompass
all
of
the
major
seed
treatment
uses
of
PCNB
throughout
the
country.
The
assumptions
and
uncertainties
are
identified
below
to
be
used
in
risk
management
decisions:


Application
Rates:
The
application
rates
are
the
maximum
allowable
that
were
identified
on
the
available
product
labels.


Amount
Handled:
The
daily
lbs
treated
or
the
daily
lbs/
A
planted
are
provided
to
HED
by
BEAD
and
registrant.


Unit
Exposures:
The
unit
exposure
values
in
seed
treatment
SOP
generally
range
from
the
geometric
mean
to
the
median
for
the
selected
data
set.
The
caveats
specific
to
each
exposure
scenario
are
summarized
in
Appendix
D,
Table
D3.
While
data
from
seed
treatment
SOP
provides
the
best
available
information
on
seed
handler
exposures,
it
should
be
noted
that
some
aspects
of
the
included
studies
(
e.
g.,
duration,
lbs
of
seed
treated,
pounds
of
active
ingredient
handled)
may
not
accurately
represent
labeled
uses
in
all
cases.

2.1.2
Seed
Handler
Risks
Table
6
presents
the
exposure
scenarios,
amount
treated
and
amount
planted
(
i.
e.,
lbs
of
seed
or
lbs/
A
planted)
that
have
been
used
in
the
exposure
calculations.
PCNB
labels
include
a
multitude
of
uses
and
a
wide
range
of
application
rates.
Therefore,
the
rates
presented
in
Table
6
are
not
all
inclusive
and
an
attempt
has
been
made
to
assess
a
range
of
application
rates
to
capture
exposure
associated
within
each
scenario.

Seed
treatment
data
base
consists
of
6
exposure
scenarios.
The
assumptions
in
this
data
base
are
based
on
the
fact
that
the
magnitude
of
handler
exposures
to
pesticides
are
primarily
a
function
of
activity
(
e.
g.,
loader/
applicator,
baggers,
sewers),
and
clothing
scenarios
(
e.
g.,
gloves,
double
layer
clothing).
Data
are
selected
for
a
given
scenario
and
normalized
(
i.
e.,
divided
by)
by
the
amount
of
pesticide
handled
resulting
in
standard
unit
exposures
(
milligrams
of
exposure
per
pound
of
active
ingredient
handled).
Following
normalization,
the
data
are
statistically
summarized.
The
distribution
of
exposure
values
is
categorized
as
normal,
lognormal,
or
"
other"
(
i.
e.,
neither
normal
nor
lognormal).
A
central
tendency
value
is
then
selected
from
the
distribution
of
the
exposure
values
for
each
activity.
These
values
are
the
geometric
mean
for
lognormal
distributions,
and
the
median
for
all
"
other"
distributions
and
are
presented
in
table
7.

Calculations
of
Exposure
Potential
daily
dermal
exposure
is
calculated
using
the
following
formula:

Daily
Dermal
Exposure
(
mg
ai/
day)
=

Dermal
Unit
Exposure
(
mg
ai/
lb
ai)
x
Application
Rate
(
lb
ai/
lb
of
seed
)
x
Daily
amount
Treated
(
lbs)

Potential
daily
inhalation
exposure
is
calculated
using
the
following
formula:
21
Daily
Inhalation
Exposure
(
mg
ai/
day)
=

Inhalation
Unit
Exposure
(
mg
ai/
lb
ai)
x
Application
Rate
(
lb
ai/
lb
of
seed)
x
Daily
amount
Treated
(
lbs)

These
calculations
of
potential
daily
exposure
to
PCNB
by
seed
treatment
handlers
are
used
to
calculate
the
absorbed
doses
and
total
risk
to
those
handlers.

Calculation
OF
Risk
Using
the
daily
dermal
exposure
scenarios
identified
in
the
exposure
section,
HED
calculated
the
potential
risk
to
persons
from
handler
exposures.

The
inhalation
and
dermal
daily
doses
were
calculated
using
the
following
formulas:

Daily
dermal
dose
(
mg/
kg/
day)
=
daily
dermal
exposure(
mg
ai/
day)/
body
weight(
kg)
x
dermal
absorption
factor(
100%)

Daily
Inhalation
dose
(
mg/
kg/
day)
=
daily
Inhalation
exposure(
mg
ai/
day)/
body
weight(
kg)
x
100%

The
MOEs
were
calculated
using
the
following
formulas:

Dermal
MOE=
Daily
Dermal
Dose
(
mg/
kg/
day)/
Dermal
NOAEL(
mg/
kg/
day)

Inhalation
MOE=
Daily
Inhalation
Dose
(
mg/
kg/
day)/
Inhalation
NOAEL(
mg/
kg/
day)

Margins
of
exposure
(
MOEs)
were
calculated
for
handlers
for
short­
term
(
up
to
1
month)
and
intermediate­
term
(
1
to
6
months)
durations.
The
assessment
includes
MOE
calculations
for
the
surrogate
data
from
seed
treatment
SOP.
The
short­
term
duration
is
believed
to
be
most
representative
of
on­
farm
seed
treaters
and
the
intermediate­
term
duration
represents
commercial
seed
treaters
who
may
repeatedly
apply
PCNB
for
1
to
6
months.

HED
calculated
the
baseline,
minimum
PPE,
maximum
PPE
MOEs
for
each
occupational
exposure
scenario
using
the
following
assumptions:

All
Scenarios:
All
occupational
handlers
are
wearing
footwear
(
socks
plus
shoes
or
boots),
foot
exposure
is
not
traditionally
monitored,
and
therefore,
a
100
percent
protection
factor
is
implied.

Baseline
Attire:
Seed
treaters
using
on­
farm,
bagging,
sewing
techniques
and
are
wearing
long­
sleeved
shirts,
long
pants,
no
gloves,
and
no
respirator.

presented
in
appendix
B
(

and
are
summarized
in
Table

Margins
of
exposure
(
MOEs)
were
calculated
for
seed
treatment
handlers
and
planters
for
short­
term
(
up
to
1
month)
and
intermediate­
term
(
1
to
6
months)
durations.
The
assessment
includes
MOE
calculations
for
various
feasible
levels
of
personal
protective
equipment
(
PPE)
using
the
surrogate
data
from
seed

SOP.

The
results
of
the
short­
and
intermediate­
term
seed
handler
assessments
indicate
that
for
all
formulations
the
majority
of
the
potential

provide
total

a
smaller
facility
performing
multiple
activities
might
require

in
order
to
have

of
greater
than

There
is
no
separate
measurement
of
exposure
for

therefore
it
is
not
feasible
to

OCCUPATIONAL
EXPOSURES
(
HANDLER
and
POSTAPPLICATION)

3.1
Occupational
Handlers
3.1.1
Handler
Exposures
Scenarios
HED
has
determined
that
there
are
potential
exposures
to
mixers,
loaders,
applicators,
or
other
handlers
during
usual
use­
patterns
associated
with
PCNB.
Based
on
the
use
patterns
and
potential
exposures
described
in
Section
1.3,
103
agricultural
and
ornamental
exposure
scenarios
are
identified
to
represent
the
extent
of
PCNB
uses.

The
potential
handler
exposures
to
the
103
exposure
scenarios
are
assessed
in
this
RED
chapter
using
the
toxicological
endpoints
and
uncertainty
factors
associated
with
the
active
ingredient.
Therefore,
the
level
of
personal
protective
equipment
(
PPE)
is
determined
by
the
assessment
of
the
active
ingredient
independently
from
the
currently
required
risk
mitigation
measures
on
PCNB
labels.
This
distinction
of
determining
risk
mitigation
measures
based
on
the
active
ingredient
instead
of
the
label
required
PPE
is
important
because
of
the
nature
of
the
enduse
products.
For
example,
some
end­
use
products
may
require
additional
PPE
because
of
the
end­
use
product's
potential
for
eye
and/
or
skin
irritation
.
Conversely,
HED
does
not
want
to
mandate
additional
PPE
(
e.
g.,
heat
stress
issues)
if
it
is
not
required
based
on
the
endpoint
and
uncertainty
factors.
There
are
some
PPE,
such
as
chemical­
resistant
aprons
and/
or
head
gear,
that
the
HED
uses
as
qualitative
measures
because
there
are
no
recognized
protection
factors
(
PF)
to
assess
their
effectiveness.
The
Agency's
risk
managers
require
these
types
of
PPE
as
additional
mitigation
of
risk.
For
example,
chemical­
resistant
aprons
are
often
required
to
protect
mixer/
loaders
from
accidental
spills.
.

For
occupational
RED
chapters
process,
HED
presents
the
risks
separately
for
some
scenarios
and
combines
others.
Most
of
the
hand­
held
equipment
such
as
push
type
granular
spreaders
are
assessed
as
mixer/
loader/
applicators,
a
combined
function.
With
these
types
of
small
operations
the
mixing,
loading,
and
applying
are
almost
always
carried
out
by
the
same
individual.
There
are
data
available
to
estimate
exposure
from
these
small
area
activities.
For
equipment
such
as
groundboom
tractors,
or
airblast
sprayers
the
tasks
are
assessed
separately
for
mixer/
loaders
and
applicators.
By
separating
the
two
job
functions,
HED
can
determine
the
most
appropriate
PPE
or
engineering
control
without
requiring
the
handler
to
wear
PPE
throughout
the
entire
workday
or
engineering
controls
that
are
not
needed.

3.1.2
Summary
of
Uncertainties
The
handler
exposure
assessments
encompass
all
of
the
major
uses
of
PCNB
throughout
the
country.
It
is
difficult
to
assess
all
of
the
"
typical"
agricultural
uses
(
i.
e.,
actual
or
predominate
application
rates
and
farm
sizes),
and
therefore,
an
assessment
has
been
developed
that
believed
to
be
realistic
and
yet
provides
a
reasonable
certainty
that
the
exposures
are
not
underestimated.
The
assumptions
and
uncertainties
are
identified
below
to
be
used
in
risk
25
management
decisions:


Application
Rates:
The
application
rates
are
the
maximum
allowable
that
were
identified
on
the
available
product
labels.


Acres
Treated:
The
daily
acres
treated
are
HED
standard
values
(
EXPO
SAC
policy
9.1).


Unit
Exposures:
The
unit
exposure
values
calculated
by
PHED
generally
range
from
the
geometric
mean
to
the
median
of
the
selected
data
set.
To
add
consistency
and
quality
control
to
the
values
produced
from
this
system,
the
PHED
Task
Force
has
evaluated
all
data
within
the
system
and
has
developed
a
set
of
grading
criteria
to
characterize
the
quality
of
the
original
study
data.
The
assessment
of
data
quality
is
based
on
the
number
of
observations
and
the
available
quality
control
data.
These
evaluation
criteria
and
the
caveats
specific
to
each
exposure
scenario
are
summarized
in
Appendix
D,
Table
D1.
While
data
from
PHED
provides
the
best
available
information
on
handler
exposures,
it
should
be
noted
that
some
aspects
of
the
included
studies
(
e.
g.,
duration,
acres
treated,
pounds
of
active
ingredient
handled)
may
not
accurately
represent
labeled
uses
in
all
cases.


Amount
Handled:
The
daily
acres
treated
are
HED
standard
values
(
see
Table
9).
Deviations
from
these
standard
values
include
the
airblast
acreage
for
magnolia
tree.
The
acreage
is
assessed
at
20
acres
because
magnolia
trees
are
grown
in
smaller
plots.

3.1.3
Handler
Risks
Table
9
presents
the
exposure
scenarios,
application
rates,
and
amount
treated
(
i.
e.,
acres
or
gallons
)
that
have
been
used
in
the
exposure
calculations.
PCNB
labels
include
a
multitude
of
uses
and
a
wide
range
of
application
rates.
Therefore,
the
rates
presented
in
Table
6
are
not
all
inclusive
and
an
attempt
has
been
made
to
assess
a
range
of
application
rates
to
capture
exposure
associated
within
each
scenario.

PHED
V1.1
has
been
used
to
assess
the
exposure
scenarios
for
PCNB.
PHED
was
designed
by
a
Task
Force
of
representatives
from
the
U.
S.
EPA,
Health
Canada,
the
California
Department
of
Pesticide
Regulation,
and
member
companies
of
the
American
Crop
Protection
Association.
PHED
is
a
software
system
consisting
of
two
parts
­­
a
database
of
measured
exposure
values
for
workers
involved
in
the
handling
of
pesticides
under
actual
field
conditions
and
a
set
of
computer
algorithms
used
to
subset
and
statistically
summarize
the
selected
data.
Currently,
the
database
contains
values
for
over
1,700
monitored
individuals
(
i.
e.,
replicates).

Users
select
criteria
to
subset
the
PHED
database
to
reflect
the
exposure
scenario
being
26
evaluated.
The
subsetting
algorithms
in
PHED
are
based
on
the
central
assumption
that
the
magnitude
of
handler
exposures
to
pesticides
are
primarily
a
function
of
activity
(
e.
g.,
mixing/
loading,
applying),
formulation
type
(
e.
g.,
wettable
powders,
granulars),
application
method
(
e.
g.,
aerial,
groundboom),
and
clothing
scenarios
(
e.
g.,
gloves,
double
layer
clothing).
Once
the
data
for
a
given
exposure
scenario
has
been
selected,
the
data
are
normalized
(
i.
e.,
divided
by)
by
the
amount
of
pesticide
handled
resulting
in
standard
unit
exposures
(
milligrams
of
exposure
per
pound
of
active
ingredient
handled).
Following
normalization,
the
data
are
statistically
summarized.
The
distribution
of
exposure
values
for
each
body
part
(
e.
g.,
chest,
upper
arm)
is
categorized
as
normal,
lognormal,
or
"
other"
(
i.
e.,
neither
normal
nor
lognormal).
A
central
tendency
value
is
then
selected
from
the
distribution
of
the
exposure
values
for
each
body
part.
These
values
are
the
arithmetic
mean
for
normal
distributions,
the
geometric
mean
for
lognormal
distributions,
and
the
median
for
all
"
other"
distributions.
Once
selected,
the
central
tendency
values
for
each
body
part
are
composited
into
a
"
best
fit"
exposure
value
representing
the
entire
body.

Calculation
Of
Risk
Using
the
daily
dermal
exposure
scenarios
identified
in
the
exposure
section,
HED
calculated
the
potential
risk
to
persons
from
handler
exposures.

The
inhalation
and
dermal
daily
doses
were
calculated
using
the
following
formulas:

Daily
dermal
dose
(
mg/
kg/
day)
=
daily
dermal
exposure(
mg
ai/
day)/
body
weight(
kg)
x
dermal
absorption
factor(
100%)

Daily
Inhalation
dose
(
mg/
kg/
day)
=
daily
Inhalation
exposure(
mg
ai/
day)/
body
weight(
kg)
x
100%

The
MOEs
were
calculated
using
the
following
formulas:

Dermal
MOE=
Daily
Dermal
Dose
(
mg/
kg/
day)/
Dermal
NOAEL(

Risks
Summary
Margins
of
exposure
(
MOEs)
were
calculated
for
handlers
for
short­
term
(
up
to
1
month)
and
intermediate­
term
(
1
to
6
months)
durations.
The
assessment
includes
MOE
calculations
for
various
levels
of
personal
protective
equipment
(
PPE)
using
the
surrogate
data
from
PHED.
The
short­
term
duration
is
believed
to
be
most
representative
of
private
growers
and
the
intermediateterm
duration
represents
commercial
applicators
who
may
repeatedly
apply
PCNB
for
1
to
6
months.

HED
calculated

All
Scenarios:
All
occupational

are
wearing
footwear
(
socks
plus
shoes
or
boots),
foot
exposure
is
not
traditionally
monitored,
and
therefore,
a
100
percent
protection
factor
is
implied.

The
results
of
the
dermal
handler
risk
assessment
for
both
the
short­
and
intermediate­
term
exposure
durations
are
summarized
in
Table
10.

The
risk
calculations
for
dermal
short­
and
intermediate­
term
exposure
risk
calculations
resulted
largely
in
MOEs
greater
than
or
equal
to
100,
with
use
of
PPE
or
engineering
controls.
The
following
scenarios
did
not
have
MOEs
greater
than
or
equal
to
100
at
any
mitigation
level:

The
agricultural
results
of
the
short­
and
intermediate­
term
occupational
handler
assessments
indicate
that
for
the
dry
flowable
formulation
the
majority
of
the
potential
exposure
scenarios
provide
total
MOE(
s)
greater
than
or
equal
to
100
at
the
baseline
clothing
attire
of
long
pants,
long
sleeved
shirts,
no
gloves,
and
no
respirator
while
using
open
systems.
For
the
liquid
formulation,
the
risks
indicate
that
in
order
for
the
mixer/
loaders
to
achieve
MOEs
of
100
for
all
uses
at
both
the
short­
and
intermediate­
term
exposure
durations
that
minimum
PPE
clothing
attire
be
required
(
i.
e.,
long
pants,
long
sleeved
shirts,
chemical
resistant
gloves,
and
a
dust/
mist
33
respirator
while
using
open
systems).
For
the
wettable
powder
formulation
risks
indicate
that
in
order
for
the
mixer/
loaders
to
achieve
MOEs
of
100
for
all
uses
at
both
the
short­
and
intermediate­
term
durations
that
some
uses
should
be
packaged
in
water
soluble
packets
(
clothing
attire
of
long
pants,
long
sleeved
shirts,
chemical
resistant
gloves,
and
no
respirator).
The
risk
for
the
majority
of
uses
with
wettable
powder
is
acceptable.
Dust
formulation
was
only
used
for
seed
treatment
and
have
acceptable

Postapplication
Exposure
Chemical
specific
post­
application
exposure
data
have
not
been
submitted
by
the
registrant
in
support
of
reregistration
of
PCNB.
There
is
a
low
potential
for
occupational
post­
application
exposure
when
a
pre­
plant
or
at
planting
fungicide
is
used.
PCNB
is
applied
to
the
soil
directly
and
is
soil
incorporated
well
before
the
plants
are
mature.
Further,
the
timing
of
the
application
greatly
reduces
the
potential
for
post
application
exposure
to
treated
foliage
and/
or
soil.
Also,
many
agricultural
operations
mechanically
plant
seeds
early
in
the
season,
which
minimizes
the
potential
for
contact.
Significant
exposure
during
harvesting
or
any
other
late
season
activities,
is
not
likely
since
the
chemical
is
applied
pre­
plant.
Therefore,
HED
does
not
require
a
post
application
assessment
for
seed
treatment
or
agricultural
uses.
However
the
Agency
has
determined
that
there
are
potential
postapplication
exposures
to
individuals
re­
entering
PCNB
treated
areas
for
the
purpose
of:

Roadsides:
mowing;
Bermuda

(
40.2
percent

were
quantified
using
the
Modified
California
Roller
technique
for
collecting
residues.
A
cotton
sheet
and
a
plastic
sheet
are
attached
to
a
sampling
frame,
and
placed
on
the
turf
test
area,
cotton

down;
then
a
weighted,
foam­
covered
roller
is
rolled
over
the
sheet
five
times,
the
sheet
is
collected
and
analyzed
for
residues.
The
study
called
for
two
turf
applications
of
12
oz
product
(
0.75
lb
a.
i.)
per
1000
ft2
to
be
made
on
different
varieties
of
grass
in
California
(
CA),
Oregon
(
OR),
and
Missouri
(
MO)
using
ground
application
equipment.
Two
applications
were
made
3
weeks
apart
at
all
sites.

Field
fortification
recoveries
averaged
over
92%
at
CA,
92%
at
OR,
and
78
%
at
MO
sites.
Most
EPA
Series
875
Study
Guidelines
were
met
by
the
studies.
There
was
a
wide
range
of
variance
in
daily
field
data
at
each
site,
from
as
little
as
5.94%
to
29%,
although
most
were
less
than
30%.
There
are
no
strict
guidelines
for
acceptability
of
field
variance,
but
high
levels
decrease
confidence
in
the
data.

The
data
were
adjusted
for
field
recoveries
below
the
90%
guideline
criterion.
The
data
were
then
analyzed
by
HED,
using
semi­
log
regression
of
the
PCNB
residues
for
each
site
separately.
The
predicted
initial
TTR
for
the
CA
site
was
0.53
µ
g/
cm2
(
R2
=
0.95)
with
a
half­
life
of
1.7
days.
The
predicted
half­
life
for
the
OR
site
was
2.0
days,
with
an
initial
residue
of
0.22
µ
g/
cm2
(
R2
=
0.78).
The
predicted
half­
life
for
the
MO
site
was
1.7
days,
with
an
initial
residue
of
46
0.59
µ
g/
cm2
(
R2
=
0.86).
The
analysis
shows
an
initial
deposition
of
about
0.13%
of
the
active
ingredient
applied.

Residential
and
Other
Non­
Occupational
Exposures
and
Risks
There
is
a
potential
for
exposure
in
residential
settings
during
the
application
process
for
homeowners
who
use
products
containing
PCNB.
There
is
also
a
potential
for
exposure
from
entering
areas
treated
with
PCNB,
such
as
entering
treated
lawn
that
could
lead
to
exposures
for
adults
and
children.
As
a
result,
risk
assessments
have
been
completed
for
both
residential
handler
and
postapplication
scenarios.

4.1
Residential
Handler
Exposures
and
Risks
The
Agency
uses
the
term
"
handlers"
to
describe
those
individuals
who
are
involved
in
the
pesticide
application
process.
Residential
handlers
are
addressed
somewhat
differently
by
the
Agency
as
homeowners
are
assumed
to
complete
all
elements
of
an
application
with
little
use
of
any
protective
equipment.

4.1.1
Residential
Handler
Exposure
Scenarios,
Data
and
Assumptions
Much
of
the
process
for
residential
uses
is
identical
to
that
considered
for
the
occupational
assessment
with
a
few
notable
exceptions
that
include:

°
Residential
handler
exposure
scenarios
are
only
considered
to
be
short­
term
in
nature
due
to
the
episodic
uses
associated
with
homeowner
products;

°
Homeowner
handler
assessments
are
completed
based
on
individuals
wearing
shorts
and
short­
sleeved
shirts;

°
Homeowner
handlers
are
expected
to
complete
all
tasks
associated
with
the
use
of
a
pesticide
product
including
mixing/
loading
if
needed
as
well
as
the
application;

°
Label
use
rates
and
use
information
specific
to
residential
products
serve
as
the
basis
for
the
risk
calculations
as
opposed
to
the
rates
used
in
the
occupational
assessment;
and
°
Area/
volumes
of
spray
or
chemical
used
in
the
risk
assessment
are
based
on
HED
guidance
specific
to
residential
use
patterns.

Exposure
to
pesticide
handlers
is
likely
during
the
residential
use
of
PCNB
in
a
variety
of
environments
including
on
turf.
The
anticipated
use
patterns
and
current
labeling
indicate
several
major
residential
exposure
scenarios
based
on
the
types
of
equipment
and
techniques
that
can
potentially
be
used
to
make
PCNB
applications.
The
quantitative
exposure/
risk
assessment
developed
for
residential
handlers
is
based
on
these
scenarios.

Data
and
Assumptions
For
Handler
Exposure
Scenarios
A
series
of
assumptions
and
exposure
factors
served
as
the
basis
for
completing
the
residential
handler
risk
assessments.
Each
assumption
and
factor
is
detailed
below.
In
addition
to
these
factors,
unit
exposure
values
were
used
to
calculate
risk
estimates.
These
unit
exposure
values
were
taken
from
the
Pesticide
Handlers
Exposure
Database
(
PHED)
or
from
Outdoor
Residential
Exposure
Task
Force
(
ORETF)
data.

The
assumptions
and
factors
used
in
the
risk
calculations
include:


Exposure
factors
used
to
calculate
daily
exposures
to
handlers
were
based
on
applicable
data
if
available.
For
lack
of
appropriate
data,
values
from
a
scenario
deemed
similar
enough
by
the
assessor
might
be
used.


The
Agency
always
considers
the
maximum
application
rates
allowed
by
labels
in
its
risk
assessments
to
consider
what
is
legally
possible
based
on
the
label.


Residential
risk
assessments
were
not
based
on
what
could
be
applied
in
a
typical
workday
like
with
the
occupational
risk
assessments
presented
above.
Instead,
the
HED
based
calculations
on
what
would
reasonably
be
treated
by
homeowners
such
as
the
size
of
a
lawn,
or
the
size
of
a
garden.
This
information
was
used
by
the
HED
to
define
chemical
use
values
for
handlers
which
in
turn
were
coupled
with
unit
exposure
values
to
calculate
risks.
The
factors
used
for
the
PCNB
assessment
were
those
presented
in
the
Health
Effects
Division
Science
Advisory
Committee
Policy
12:
Recommended
Revisions
To
The
Standard
Operating
Procedures
For
Residential
Exposure
Assessment
which
was
completed
on
February
22,
2001.
The
following
daily

and

excerpted
from
the

4.1.2
Residential
Handler
Exposure
and
Risk
Estimates
The
residential
handler
exposure
and
risk
calculations
are
presented
in
this
section.
Risks
were
calculated
using
the
Margin
of
Exposure
(
MOE).
The
major
difference
with
residential
risk
assessments
is
that
the
uncertainty
factor
which
defines
the
level
of
risk
concern
also
has
the
additional
FQPA
safety
factor
applied.
In
the
case
of
PCNB,
the
overall
uncertainty
factor
applied
to
residential
handler
risk
assessments
is
1000.

In
residential
settings,
the
Agency
does
not
use
personal
protective
equipment
to
limit
exposures,
because
they
are
viewed
as
impractical
and
not
enforceable.
Risk
estimates
are
based
on
handlers
wearing
short­
sleeve
shirts,
short
pants,
shoes,
and
socks.
Residential
risks
are
of
concern
for
a
few
scenarios,
(
i.
e.,
MOE
<
1000)
for
non
cancer
risk
assessments
in
non
occupational
settings.
The
scenarios
where
MOEs
do
not
meet
the
Agency's
target
MOE
uncertainty
factor
for
non
cancer
risk
assessments
include
dermal
risk
for
mixing/
loading/
applying
liquid
with
low
pressure
handwand
and
dermal
and
inhalation
risk
for
garden
hose­
end
sprayer
and
belly
grinder.

The
residential
handler
scenarios
that
are
not
of
concern
(
i.
e.,
MOE

1000)
for
shortand
intermediate­
term
dermal
and
inhalation
risks
are
backpack
sprayer
application
and
push
type
spreader.

NON­
OCCUPATIONAL
POST­
APPLICATION
EXPOSURE
AND
RISK
ESTIMATES
4.2.1
Post­
Application
Exposure
Scenarios,
Data,
and
Assumptions
Adults
and
children,
are
potentially
exposed
to
residues
after
application
of
PCNB
products
in
residential
settings.
After
application
to
turf,
short­
to
intermediate­
term
dermal
exposures
are
anticipated
for
adults
and
children.
Incidental
oral
exposure
is
also
expected
to
occur
for
small
children
and
is
combined
with
their
dermal
exposures,
where
applicable
(
i.
e.,
playing
on
turf).
The
physical
and
behavioral
differences
between
adults
and
children
are
continuously
being
studied
by
the
Agency,
and
the
current
standard
assumptions
set
forth
by
the
HED
and
the
Science
Advisory
Panel
(
SAP)
are
contained
in
the
Residential
SOPs.
The
SOPs
were
updated
in
February,
2001.

HED
always
completes
short­
and
intermediate­
term
risk
assessments
using
maximum
application
rates
for
each
scenario
because
what
is
possible
under
the
label
must
be
evaluated
for
complete
stewardship
in
order
to
ensure
HED
has
no
concern
for
the
specific
use.

The
scenarios
likely
to
result
in
postapplication
exposures
are
presented
below.
Because
the
label
prohibits
application
more
than
2
times
per
year,
and
even
with
the
slow
dissipation
rates,
it
is
not
expected
that
individual
residential
exposure
duration
would
exceed
30
days
in
duration.
Exposure
on
a
residential
lawn
would
diminish
continuously
with
time,
while
exposure
through
recreation
turf
contact
would
be
more
like
random
intermittent
events
of
varying
doses,
all
less
than
the
dose
predicted
in
this
assessment.
Residential
postapplication
exposure
assessments
assumed
residents
wear
the
following
attire:
short
sleeved
shirt,
short
pants,
shoes
and
socks,
and
no
gloves
or
respirator.
As
stated
in
the
occupational
postapplication
risk
section
of
this
document,
negligible
PCNB
inhalation
exposure
is
anticipated
for
non­
handlers,
due
to
low
chemical
vapor
pressure
and
dilution
of
vapor
outdoors.
The
scenarios
likely
to
result
in
postapplication
exposures
are
as
follows:

°
dermal
postapplication
risks
to
adults
and
toddlers
when
entering
PCNB
treated
turf
and
lawns;

°
oral
postapplication
risks
to
toddlers
from
"
hand­
to­
mouth"
(
i.
e.,
ingestion
of
grass,
soil,
or
hand­
to­
mouth
contact)
exposure
when
reentering
lawns
treated
with
granular
liquid
51
and
wettable
powder
formulations.

Representative
turf
reentry
activities
include,
but
are
not
limited
to:

(
1)
Adults
involved
in
a
low
exposure
activity,
such
as
golfing
or
walking
on
treated
turf.
(
2)
Toddlers
involved
in
a
low
exposure
activity,
such
as
walking
on
treated
turf.
(
3)
Adults
mowing
or
other
moderate
contact
activity,
for
1­
2
hours.
(
4)
Adults
involved
in
a
high
exposure
activity,
such
as
heavy
yard
work
(
doses
similar
to
occupational
scenarios
for
cutting
and
harvesting
sod).
(
5)
Toddlers
involved
in
high
exposure
activities
on
turf.

Although
a
Turf
Transferable
Residue
(
TTR)
study
(
MRID#
44687101)
was
submitted
in
support
of
the
reregistration
of
PCNB
but,
it
was
found
to
be
not
acceptable
for
this
assessment.
The
TTR
study
was
reviewed
and
found
to
have
TTR
transfer
efficiencies
of
less
than1%
(
transfer
efficiency
=
%
of
the
application
rate).
TTR
data
generated
by
ORETF
members
rely
on
a
modified
version
of
the
California
roller
(
ORETF
roller)
that
appears
to
have
a
much
lower
transfer
efficiency
(
percent
of
application
rate)
than
the
original
version.
Many
TTR
data
submitted
by
ORETF
members
show
percent
transferabilities
of
less
than
1%
of
the
application
rate
for
sprayable
formulations
and
less
than
0.5%
of
the
application
rate
for
granular
formulations.
ORD
has
conducted
a
round
robin
test
of
TTR
methods
that
included
the
ORETF
roller
(
Fortune
1997).
While
ORD
concluded
that
the
ORETF
roller
performed
the
best
of
all
methods,
transfer
efficiency
for
three
liquid
herbicide
formulations
indicated
a
transfer
efficiency
of
~
0.5%.
The
ORETF
data
was
not
used
with
the
revised
Transfer
Coefficients
referenced
in
current
residential
SOP
since
these
revised
TCs
are
based
on
TTR
transfer
efficiencies
of
~
1­
5%
(
transfer
efficiency
=
%
of
the
application
rate).
Therefore
the
TTR
values
from
this
study
is
not
included
in
this
assessment.

Dermal
Exposure
to
Golf
Course
Turfgrass
According
to
a
1992
report
from
The
Center
For
Golf
Course
Management,
12.2
percent
of
the
population
are
golfers
(
i.
e.,
28.5
million
people).
Golfing
is
considered
a
lifetime
sport
so
individuals
of
all
ages,
excluding
very
small
children,
routinely
play.
Children
who
are
12
years
of
age
or
older
are
likely
to
represent
the
vast
majority
of
the
youth
that
play
golf
on
any
sort
of
routine
basis.
However,
the
popularity
of
golf
as
a
recreational
pastime
has
increased
steadily
over
the
last
few
years
which
has
resulted
in
more
and
more
young
children
(
i.
e.,
less
than
12
years
old
for
this
discussion)
becoming
involved
in
the
sport.
Risk
assessments
for
these
age
children
are
more
difficult
to
complete
because
of
the
increased
uncertainties
associated
with
any
extrapolations
using
adult
dermal
exposure
data
and
because
of
the
increased
likelihood
that
other
behaviors
that
might
contribute
to
exposure
such
as
mouthing
contaminated
hands
or
golf
balls.

The

calculated

can
be

of

because
of
several
reasons
including
the

Once

of

scenarios.

Hand
to
Mouth
Transfer
The
following
demonstrates
the
method
used
to
calculate
exposures
that
are
attributable
to
a
child
touching
treated
turf
and
then
putting
their
hands
in
their
mouth
(
SOP
2.3.2):

(

where:
PDR
=
potential

(

AR
=

rate
(
lb

F­
DR
=

dislodgeable
from
wet
hands
(
5%)
CF
=
conversion
factor
to
convert
lb
ai/
A
to

g/
cm2
(
11.2)
SA
=
surface
area
of
1
to
3
fingers
(
20
cm2);
EXT
=
extraction
rate
by
saliva
(
50%)
Freq
=
frequency
of
hand­
to­
mouth
events
(
20
events/
hour);
and
Hr
=
exposure
duration
(
2
hours)

As
indicated
above,
the
dislodgeable
foliar
residue
represents
the
amount
of
pesticide
that
can
be
removed
from
turf
by
the
(
potentially
wet)
hands
of
a
child,
while
the
turf
transferable
residue
represents
the
amount
of
chemical
on
the
surfaces
of
treated
leaves
that
can
rub
off
on
dry
skin
or
clothing.
These
observations
are
based
on
empirical
data,
and
therefore
the
Residential
SOP
standard
5%
of
the
amount
ai
applied
is
used,
rather
than
the
data
from
the
TTR
study.
The
surface
area
for
1­
3
fingers
used
(
20
cm2)
is
the
median
surface
area
for
a
toddler
(
age
3
years)
as
updated
by
the
SAP
in
12/
99.
The
frequency
of
hand­
to­
mouth
events
is
20
events
per
hour
as
updated
in
12/
99.
The
2
hour
duration
value
is
a
recommended
value
from
the
U.
S.
EPA
Exposure
Factors
Handbook.
This
model
for
hand­
to­
mouth
dose
is
based
on
the
premise
that
a
child
puts
2­
3
fingers
in
their
mouths,
50%
of
the
residues
on
the
hands
are
transferred
from
the
hands
to
the
mouth,
and
that
all
of
the
dislodgeable
residues
available
on
the
treated
turf
transfer
to
the
child's
hand
each
time
they
exhibit
this
behavior.

The
following
illustrates
the
approach
used
to
calculate
exposures
that
are
attributable
to
a
child
mouthing
treated
turf
(
SOP
2.3.3):
where:
55
PDR
=
(
AR
*
F­
DR
*
CF
*
IgR
*
(
1
mg/
1000

g)

where:
PDR
=
potential
dose
rate
(
mg/
day);
AR
=
application
rate
F­
DR
=
fraction
of
residue
dislodgeable
from
contaminated
object
(
20%)
CF
=
conversion
factor
to
convert
lb
ai/
A
to

g/
cm2
(
11.2)
IgR
=
ingestion
rate
for
mouthing
of
grass
per
day
(
25
cm2/
day)

The
ingestion
rate
used
(
25
cm2/
day)
assumes
that
a
child
will
grab
a
handful
of
turf
or
contaminated
object,
mouth
it
and
remove
all
PCNB
residues,
and
then
remove
it
from
their
mouth.
The
surface
area
of
(
25
cm2/
day)
is
thought
to
approximate
a
handful
of
turf
that
is
mouthed.

Incidental

The
following
is
the
formula
used
to
estimate
exposure
from

The
following
specific
assumptions
and
factors
were
used
in
order
to
complete
this
exposure
assessment:


These
assessments
were
based
on
the
guidance
provided
in
the
Residential
SOPs
and
updated
in
Revisions
to
the
SOPs
(
February
2001)
based
on
the
1999
SAP
comments.
Several
of
the
assumptions
and
factors
used
in
the
exposure
assessment
are
described
in
that
document.


Calculations
for
short­
term
risks
are
based
on
the
maximum
application
rate
for
turf,


Due
to
a
lack
of
chemical­
specific
exposure
data,
HED
has
calculated
exposure
values
for
adults
using
surrogate
dermal
transfer
coefficients
that
represent
activities
such
as
mowing,
golfing,
and
yard
work.

For
PCNB,
a
70
kg
median
body
weight
for
dermal
exposures
for
all
adults
was
used.
The
average
body
weight
used
in
all
assessments
for
3­
year
old
children
is
15
kg
based
on
the
SOPs
For
Residential
Exposure
Assessment.
For
oral
exposures
for
children,
the
oral
NOAEL
of
1
mg/
kg/
day
for
general
population
is
used.
57
The
NOAELs
and
the
uncertainty
factors
that
apply
to
all
PCNB
risk
estimates
are
listed
in
Section
1.1
above.
The
non­
occupational
target
MOE
is
1000
for
PCNB.
MOEs
were
calculated
using
the
following
formula:

Where:
MOE
=
ADD/
NOAEL
MOE=
margin
of
exposure
or
ratio
of
chemical
exposure
to
the
endpoint
of
concern;

Absorbed
Daily
Dose
(
ADD)=
the
absorbed
dose
received
from
exposure
to
a
pesticide
in
a
given
scenario
(
mg
pesticide
active
ingredient/
kg
body
weight/
day);
and
NOAEL=
the
highest
dose
level
in
a
toxicity
study
where
no
observed
adverse
effects
occur
(
mg
pesticide
active

Short­
term
PCNB

treated
turf

lawn
activities
at
applications
rate
of
32.67
lbs
ai/
A
and
43.560
lbs
ai/
A
did
exceed
the
level
of
concern
for
adults
(
MOE
30­
40)
or
for
children
(
MOE
82­
110).
Activities
such
as
golfing
and
mowing
lawns
treated
with
PCNB
at
applications
rate
of
32.67
lbs
ai/
A
resulted
in
MOEs
of
860­
1145
and
575­
430,
respectively,
and
exceeds
HED's
level
of
concern.

The
risk
calculations
for
small
children's
non­
dietary
ingestion
of
PCNB
on
treated
turf
indicate
that
risks
exceed
the
level
of
concern
for
hand­
to­
mouth
transfer
(
MOE=
2).
Incidental
turfgrass
mouthing
(
MOEs
6­
8)
and
incidental
ingestion
of
soil
(
460­
612).

Potential
residential
exposures
are
anticipated
as
a
result
of
resident
application
and
professional
lawn
care
operator
application.
Risk
estimates
were
performed
for
potential
contact
with
lawn
and
soil
treated
with
PCNB,
using
residential
SOP.

The
target
non­
occupational
MOE
was
1000
for
PCNB.
The
resulting
surrogate
residential
postapplication
assessment
indicates
that
dermal
contact
after
lawn
is
sprayed
at
typical
application
rates
would
result
in
PCNB
MOEs
of
concern
(
i.
e.,
under
the
target
of
1000).
Aggregating,
or
adding
residential
handler
exposure
and
postapplication
exposure
also
results
in
MOEs
below
1000.
.

The
Residential
SOPs
are
considered
to
be
conservative
scenarios
for
determining
risk
estimates.
The
adult
and
children's
transfer
coefficients
are
based
on
the
Jazzercise
protocol
which
represents
an
upper
percentile
exposure
duration
value.

gloves.
The
gloves
were
changed
at
the
end
of
loading.
Inhalation
exposures
were
measured
with
37
mm
glass
fiber
filters
and
the
filters
were
changed
after
loading.
The
dermal
results
were
adjusted
by
a
clothing
protection
factor
to
account
for
the
fact
that
5%
of
the
outer
residues
was
found
on
the
inner
dosimeters.
Dermal
and
inhalation
field
recoveries
were
grade
A.

13
replicates
are
from
MRID
422519­
01
which
involved
the
loading
and
drilling
of
canola
seed
treated
with
Oftanol
which
forms
a
hard
shell
coating.
The
replicates
were
located
at
one
site
in
Manitoba
using
four
different
planting
rigs.
Four
workers
participated
and
the
replicates
averaged
3.2
hours
in
duration.
The
seed
was
loaded
into
the
drill
hoppers
from
25
kg
bags.
The
amount
of
seed
handled
per
replicate
averaged
360
pounds
and
the
amount
of
ai
handled
averaged
4.33
lbs.
The
seed
was
planted
at
a
rate
of
6
to
8
pounds
per
acre.
The
same
worker
performed
both
the
loading
and
planting.
Dermal
exposure
was
measured
with
patches
located
both
inside
and
outside
the
worker's
coverall.
Hand
exposures
were
measured
by
handrinse.
Inhalation
exposures
were
measured
with
37
mm
quartz
microfiber
filters.
Dermal
and
inhalation
field
recoveries
were
grade
A.

All
handler
exposure
assessments
in
this
document
are
based
on
the
"
Best
Available"
data
as
defined
by
the
PHED
SOP
for
meeting
Subdivision
U
Guidelines
(
i.
e.,
completing
exposure
assessments).
Best
available
grades
are
assigned
to
data
as
follows:
matrices
with
A
and
B
grade
data
(
i.
e.,
Acceptable
Grade
Data)
and
a
minimum
of
15
replicates;
if
not
available,
then
grades
A,
B
and
C
data
and
a
minimum
of
15
replicates;
if
not
available,

then
all
data
regardless
of
the
quality
(
i.
e.,
All
Grade
Data)
and
number
of
replicates.
High
quality
data
with
a
protection
factor
take
precedence
over
low
quality
data
with
no
protection
factor.

The
generic
data
confidence
categories
are
assigned
as
follows:

High
=
grades
A
and
B
and
15
or
more

A,
B,
C,
D
and
E
or
any
combination
of
