Determination
1.
U.
S.
population.
Using
the
exposure
assumptions
described
above,
BASF
has
estimated
that
chronic
dietary
aggregate
exposure
to
chlorfenapyr
for
the
U.
S.
population
was
0.002615
mg/
kg
bwt/
day
or
8.7%
of
the
chronic
RfD
of
0.03
mg/
kg
bwt/
day.
Other
than
children
less
than
12
years
of
age,
hispanics
are
the
U.
S.
population
subgroup
with
the
highest
chronic
exposure
of
0.003403
mg/
kg
bwt/
day,
or
11.3%
of
the
RfD.
EPA
has
no
concerns
about
exposure
that
are
less
than
100%
of
the
RfD
as
the
RfD
represents
the
level
at
or
below
which
daily
aggregate
dietary
exposure
over
a
lifetime
will
not
pose
appreciable
risks
to
human
health.
It
is
therefore,
safe
to
conclude
that
there
is
reasonable
certainty
that
no
harm
to
the
overall
U.
S.
population
will
result
from
chronic
exposure
to
chlorfenapyr
residues.
2.
Infants
and
children.
Using
the
exposure
assumption
described
above,
BASF
has
estimated
that
the
chronic
dietary
aggregate
exposure
to
chlorfenapyr
for
children
1
 
6
years
of
age
was
0.005936
mg/
kg
bwt/
day,
or
19.8%
of
the
chronic
RfD
of
0.03
mg/
kg
bwt/
day.
Children
1
 
6
years
of
age
were
the
sub­
population
that
utilized
the
largest
portion
of
the
chronic
RfD.
It
is
therefore,
safe
to
conclude
that
there
is
reasonable
certainty
that
no
harm
to
infants
and
children
will
result
from
chronic
exposure
to
chlorfenapyr
residues.

F.
International
Tolerances
No
Codex
or
Canadian
tolerances/
limits
for
residues
in
any
food
presently
exist
for
chlorfenapyr.
In
Mexico
there
is
a
MRL
of
0.3
ppm
for
cottonseed.

A.
Residue
Chemistry
1.
Plant
metabolism.
As
a
polysaccharide
polymer,
gellan
gum
is
non­
systemic
and
therefore
no
metabolism
of
gellan
gum
in
raw
agricultural
commodities
or
processed
commodities
is
expected.
2.
Analytical
method.
Analytical
methods
for
determination
of
the
polysaccharide
polymer,
gellan
gum
are
available.
Gellan
gum
is
determined
by
the
dissolution
of
gellan
gum
containing
gels
by
heating
and
cooling
in
the
presence
of
a
dilute
sequestrant
solution
(
e.
g.
0.1%
w/
v
sodium
hexametaphosphate).
The
gellan
gum
assay
is
based
upon
the
presence
of
the
6­
deoxyhexose
rhamnose
which
can
be
determined
using
the
cysteine­
sulfuric
acid
procedure,
originally
developed
by
Dische
and
Shettles
and
modified
by
Graham.
3.
Magnitude
of
residues.
Gellan
gum
is
applied
as
a
minor
component
of
pesticidal
formulations.
Gellan
gum
degrades
into
simple
non­
toxic
sugars
and
their
salts.

B.
Toxicological
Profile
1.
Acute
toxicity.
The
acute
toxicity
of
gellan
gum
was
studied
using
male
and
female
rats
via
the
oral
and
inhalation
routes.
In
the
acute
oral
toxicity
study,
the
lethal
dose
(
LD)
50
for
both
males
and
females
was
established
at
>
5,000
milligrams/
kilogram
body
weight
(
mg/
kg
bwt).
For
the
acute
inhalation
toxicity
study,
the
LD50
for
both
males
and
females
was
established
at
>
5.09
milligrams/
Liter
(
mg/
L).
Gellan
gum
is
practically
non­
toxic
to
rats
when
administered
as
a
single
large
dose
(
5
g/
kg
bwt)
in
diet
or
via
gavage.
2.
Genotoxicity.
Gellan
gum
was
shown
to
be
non­
genotoxic
in
a
battery
of
standard
short­
term
tests.
The
Ames
test,
involving
S.
typhimurium
at
10,
30,
100,
300,
and
1,000
µ
g/
plate
resulted
in
a
negative
response.
A
deoxyribonucleic
acid
(
DNA)
repair
test
using
the
rat
hepatocyte
as
a
test
subject
at
3,
5,
10,
and
20
milligrams/
liter
(
mg/
L)
resulted
in
a
negative
response.
For
the
V
 
79/
hypoxanthine
guanine
phophoribosyl
transferase/(
HGPRT)
study,
involving
the
Chinese
hamster
lung
fibroblasts,
doses
at
3,
5,
10,
and
20
mg/
mL
resulted
in
a
negative
response.
3.
Reproductive
and
developmental
toxicity.
Groups
of
26
male
and
female
CD
(
Sprague­
Dawley)
rats
were
administered
gellan
gum
in
their
diets
at
doses
of
0,
2.5,
3.8,
or
5.0%.
Males
were
treated
for
70
days
prior
to
mating
and
for
3
weeks
after
mating.
Females
were
treated
for
14
days
prior
to
mating
and
throughout
mating,
gestation,
and
lactation.
Selection
was
made
for
the
pups
(
F1)
of
this
mating
and
they
were
allowed
to
mature
and
were
mated
to
form
the
F2
generation.
There
was
no
treatment­
related
effect
of
mating
or
fertility
index,
conception
rate,
length
of
gestation,
length
or
parturition,
number
of
live
pups,
number
of
dead
pups,
postimplantation
loss
index,
survival
index
on
day
4,
7,
14,
or
21
or
lactation
index
for
any
of
the
generations.
For
teratology
studies,
gellan
gum
was
fed
to
groups
of
25
pregnant
female
Sprague­
Dawley
rats
at
dietary
levels
of
0,
2.5,
3.8,
or
5.0%
during
days
6
 
15
of
gestation.
Gellan
gum
has
no
fetotoxic
or
teratogenic
effects
on
rats
when
ingested
in
the
diet
at
levels
up
to
5.0%.
In
the
reproduction
and
teratogenic
studies
in
rats
in
which
gellan
gum
was
given
at
doses
up
to
50
g/
kg
in
the
diet,
there
was
no
evidence
of
interference
with
the
reproductive
process,
and
no
embryotoxic
or
developmental
effects
were
observed.
4.
Subchronic
toxicity.
For
short­
term
studies,
male
and
female
Sprague­
Dawley
rats
(
20/
sex/
group)
were
fed
dietary
levels
of
gellan
gum
ranging
from
0
 
6%
for
13
weeks.
Although
the
animals
on
this
study
experienced
symptoms
of
a
sialodacryoadenitis
viral
infection,
all
animals
survived
treatment
and
there
were
no
adverse
effects
associated
with
the
feeding
of
gellan
gum
at
levels
up
to
60
gram/
kilogram
(
g/
kg).
Also,
prepubertal
rhesus
monkeys
(
2/
sex/
group)
were
dosed
by
oral
gavage
with
gellan
gum
at
levels
of
0,
1,
2,
or
3
g/
kg/
day
for
28
days.
There
were
no
overt
signs
of
toxicity
reported
at
levels
up
to
50
g/
kg
in
the
diet.
5.
Chronic
toxicity.
Groups
of
50
male
and
female
Swiss
Crl
mice
were
fed
gellan
gum
admixed
in
the
diet
at
0,
1.0,
2.0,
and
3.0%
for
96
and
98
weeks
for
males
and
females,
respectively.
All
animals
were
examined
twice
daily
for
mortality
and
morbidity.
Physical
examination
for
the
presence
of
palpable
masses
was
initiated
on
a
weekly
basis
starting
in
week
26.
Body
weights
and
food
consumption
were
measured
for
7
 
day
periods
on
a
weekly
basis
for
the
first
26
weeks
of
treatment
and
every
2
weeks
thereafter.
At
necropsy,
a
complete
gross
pathological
examination
was
performed
on
the
animals
from
the
control
and
3.0%
groups.
Only
the
liver,
kidneys,
ovaries,
testes,
adrenals,
pituitary,
lungs,
and
heart
were
examined
for
animals
of
the
1.0
and
2.0%
groups.
There
were
no
effects
attributable
to
the
feeding
of
gellan
gum
on
either
body
weight
gain
or
food
consumption.
There
were
no
neoplastic
or
non­
neoplastic
changes
which
were
associated
with
the
feeding
of
gellan
gum.
For
the
rat,
groups
of
50
F1
generation
Sprague­
Dawley
rats
of
each
sex
were
exposed
to
gellan
gum
in
utero
and
continued
on
gellan
gum
diets
for
approximately
104
weeks.
The
dietary
levels
of
gellan
gum
were
0,
2.5,
3.8,
and
5.0%.

the
first
4
weeks
of
treatment
and
weekly
thereafter
for
clinical
signs
of
toxicity.
Individual
bodyweights
and
food
consumption
were
measured
on
a
weekly
basis
for
the
first
26
weeks
of
treatment
and
every
2
weeks
thereafter.
Fundoscopic
and
biomicroscopic
examinations
were
conducted
on
the
control
and
5%
groups
during
weeks
1,
13,
26,
52,
78,
and
103.
Clinical
chemistry
and
haematological
samples
were
collected
at
weeks
13,
25,
39,
and
51.
After
104
weeks,
ophthalmoscopic
examinations,
haematology,
clinical
chemistries
and
organ
weight
data
revealed
no
changes
which
could
be
attributed
to
the
feeding
of
gellan
gum.
Survival
of
male
treated
rats
was
poor
when
compared
to
controls
whereas
female
treated
rats
exhibited
better
survival
than
their
concurrent
controls.
Male
rats,
fed
gellan
gum
at
the
3.8
and
5.0%
dietary
levels,
exhibited
lower
body
weights
after
76
weeks.
The
initial
bodyweights
were
5.2
and
3.4%
lower
than
the
control
values
for
the
3.8
and
5.0%
dietary
levels,
respectively.
It
was
concluded
that
in
spite
of
the
initial
body
weight
deficit,
the
growth
pattern
for
these
treated
groups
was
identical
to
that
of
the
control.
In
addition,
this
effect
was
not
seen
in
either
the
females
or
any
other
species
tested.
There
is
no
basis
to
suggest
that
the
lower
body
weights,
observed
in
the
male
rats,
are
indicative
of
toxicity.
Organs
and
tissues
as
those
listed
in
the
mouse
study
were
examined
for
histopathological
changes
at
study
termination.
There
were
no
neoplastic
or
non­
neoplastic
changes
that
could
be
associated
with
the
feeding
of
gellan
gum.
The
authors
concluded
that
gellan
gum
is
non­
carcinogenic
to
Sprague­
Dawley
rats.
For
chronic
toxicity
study
on
dogs,
diets
containing
0,
3,
4.5,
and
6%
gellan
gum
were
fed
to
groups
of
5
Beagle
dogs
per
sex
for
a
period
of
52
weeks.
The
dogs
were
observed
daily
for
clinical
signs
of
toxicity
and
were
measured
for
body
weights
and
food
consumption.
Ophthalmoscopic
examinations
were
performed
during
pretreatment
and
after
12,
24,
29,
and
51
weeks.
Hematology
and
clinical
chemistry
were
measured
during
pretreatment
and
after
6,
13,
25,
39,
and
50
weeks.
After
52
weeks
all
animals
were
killed
and
grossly
examined.
All
animals
survived
treatment.
Food
intake
was
higher
in
the
treated
groups
compared
to
the
controls.
There
were
no
adverse
effects
associated
with
the
feeding
of
gellan
gum
to
beagle
dogs
for
a
period
1
 
year.
6.
Animal
metabolism.
The
adsorption,
distribution,
and
excretion
of
gellan
gum
was
studied
using
a
dually
radiolabeled
(
3H
and
14C)
preparation.
The
use
of
dual
labeling
allowed
simultaneous
quantitation
of
both
polysaccharide
and
``
protein''
fractions
of
gellan
gum.
One
male
and
one
female
Sprague­
Dawley
rat
were
gavaged
with
single
doses
of
the
3H/
14C­
gellan
gum
(
ca.
960
mg/
kg;
ca.
4
µ
Ci).
Expired
air
was
collected
24
hours
after
dosing.
Less
than
0.55%
of
the
given
radioactivity
was
detected
as
14C.
Four
male
and
three
female
Sprague­
Dawley
rats
were
dosed
with
single
gavage
dose
of
3H/
14C
 
gellan
gum
(
ca.
870
mg/
kg;
2.9
­
4.1
µ
Ci
14C;
0.7
­
0.9
µ
Ci
3H).
Urine
and
feces
were
collected
for
7
days,
at
which
time
the
animals
were
sacrificed
and
their
tissues
analyzed
for
residual
radioactivity.
Females
excreted
86.8%
and
1.9%
of
the
given
14C
in
the
feces
and
urine,
respectively.
Males
excreted
86%
of
the
dosed
14C
in
the
feces
and
3.3%
in
the
urine.
Females
excreted
4.1%
of
the
dosed
3H
in
their
urine
and
100.1%
in
their
feces,
while
males
excreted
3.6%
of
the
total
3H
in
their
urine
and
99.6%
in
their
feces.
In
all
animals,
the
activities
of
3H
in
tissues
(
blood,
brain,
liver,
kidney,
lung,
muscle,
skin,
heart,
and
carcass)
were
too
low
to
be
quantitated
accurately.
Tissue
and
carcass
radioactivity
for
14C
averaged
3.8%
of
dose
for
male
rats
and
3.0%
of
dose
for
female
rats.
A
male
and
four
female
Sprague­
Dawley
rats
were
gavaged
with
about
1
g/
kg
of
radiolabeled
gellan
gum
and
blood
samples
collected
from
the
tail
vein
at
different
time
intervals
over
a
7
 
day
period.
Data
were
reported
as
14C
dmp/
mL
blood
(
3H
dmp/
mL
blood
was
not
reported).
The
peak
level
of
radioactivity,
which
amounted
to
about
0.4%
of
the
administered
radioactivity,
occurred
about
5
hours
after
dosing.
Gellan
gum
was
shown
to
be
poorly
absorbed
and
did
not
cause
any
deaths
in
rats
which
received
a
single
large
dose
(
5
g/
kg
bwt)
in
the
diet
or
by
gavage.
7.
Metabolite
toxicology.
Gellan
gum
is
a
polysaccharide
polymer
composed
of
D­
mannopyranose
with
Dglucopyranose
and
6­
deoxy­
Lmannopyronose
calcium,
potassium,
and
sodium
salt.
Gellan
gum
metabolizes
into
simple
non­
toxic
sugars
and
their
salts.
8.
Endocrine
disruption.
Gellan
gum
does
not
belong
to
a
class
of
chemicals
known
or
suspected
of
having
adverse
effects
on
the
endocrine
system.
There
is
no
evidence
that
gellan
gum
has
any
effect
on
endocrine
function
in
developmental
or
reproduction
studies.
Furthermore,
histological
investigation
of
endocrine
organs
in
chronic
dog,
rat,
and
mouse
studies
did
not
indicate
that
the
endocrine
system
is
targeted
by
gellan
gum.

C.
Aggregate
Exposure
1.
Dietary
exposure.
As
a
minor
formulation
component,
there
is
no
reasonable
expectation
that
gellan
gum
will
appear
in
diet.
i.
Food.
Gellan
gum
is
approved
in
the
U.
S.
under
21
CFR
172.665
as
a
food
additive,
stabilizer,
and
thickener
in
batters,
breadings,
coatings,
glazes,
gravies,
and
sauces
for
meat
and
poultry
products.
As
a
minor
formulation
component,
there
is
no
reasonable
expectation
that
gellan
gum
will
appear
in
food
from
pesticide
uses.
ii.
Drinking
water.
As
a
minor
formulation
component,
there
is
no
reasonable
expectation
that
gellan
gum
will
appear
in
water.
2.
Non­
dietary
exposure.
The
only
non­
dietary
exposure
to
gellan
gum
will
be
exposure
through
treating
and
handling
of
treated
seeds
and
application
of
formulations
containing
gellan
gum.

D.
Cumulative
Effects
The
potential
for
cumulative
effects
of
gellan
gum
and
other
substances
that
have
a
common
mechanism
of
toxicity
has
also
been
considered.
Gellan
gum
is
a
high­
molecular­
weight
polysaccharide
gum
produced
by
a
pure­
culture
fermentation
of
a
carbohydrate
with
Sphingomonas
elodea.
There
is
no
reliable
information
to
indicate
that
toxic
effects
produced
by
gellan
gum
would
be
cumulative
with
those
of
any
other
chemical
including
another
pesticide.
Therefore,
CP
Kelco
believes
it
is
appropriate
to
consider
only
the
potential
risks
of
gellan
gum
in
an
aggregate
risk
assessment.

Exposures
occurring
during
these
