Executive
Summary
A
chronic
dietary
risk
assessment
was
conducted
using
the
Dietary
Exposure
Evaluation
Model
(
DEEM­
FCID
 
)
,
Version
2.03,
which
uses
food
consumption
data
from
the
U.
S.
Department
of
Agriculture's
Continuing
Surveys
of
Food
Intakes
by
Individuals
(
CSFII)
from
1994­
1996
and
1998.
The
analysis
was
performed
to
support
FIFRA
§
3
registration
requests
for
the
fungicide,
quinoxyfen,
on
peppers
(
bell
and
non­
bell),
lettuce
(
head
and
leaf),
strawberry
and
melons.

No
toxic
effects
attributable
to
a
single
(
i.
e.,
acute)
exposure
to
quinoxyfen
have
been
identified;
therefore,
an
acute
Reference
Dose
(
aRfD)
has
not
been
established
for
quinoxyfen
and
an
acute
dietary
exposure
assessment
has
not
been
conducted.
Also,
since
there
is
no
evidence
that
quinoxyfen
is
carcinogenic
to
humans,
a
dietary
cancer
assessment
is
not
required.

Chronic
Dietary
Exposure
Results
and
Characterization
The
tier
1
chronic
assessment
assumed
that
quinoxyfen
residues
are
present
in
all
commodities
at
tolerance
levels
and
that
100%
of
all
crops
are
treated.
DEEM
 
Version
7.81
default
processing
factors
were
used
to
estimate
residues
in
cherry
juice,
grape
juice
and
raisins.
Drinking
water
was
incorporated
directly
into
the
dietary
assessment
using
the
estimated
drinking
water
concentration
(
EDWC)
for
surface
water
generated
by
the
PRZM­
EXAMS
model.

The
resulting
chronic
dietary
exposure
estimates
for
food
and
water
combined
are
well
below
HED's
level
of
concern
(
i.
e.,
<
100%
of
the
cPAD
of
0.2
mg/
kg
bw/
day)
for
the
overall
U.
S.
population
and
all
population
subgroups.
Using
the
DEEM­
FCID
software,
dietary
exposure
is
estimated
at
0.002596
mg/
kg/
day
for
the
U.
S.
population
(
1.3%
of
the
cPAD)
and
0.003923
mg/
kg/
day
(
2.0%
of
the
cPAD)
for
children
1
to
2
years
old,
the
population
subgroup
with
the
highest
estimated
chronic
dietary
exposure
to
quinoxyfen.

I.
Introduction
Dietary
risk
assessment
incorporates
both
exposure
and
toxicity
of
a
given
pesticide.
For
chronic
assessments,
the
risk
is
expressed
as
a
percentage
of
a
maximum
acceptable
dose
(
i.
e.,
the
dose
which
HED
has
concluded
will
result
in
no
unreasonable
adverse
health
effects).
This
dose
is
referred
to
as
the
population
adjusted
dose
(
PAD).
The
PAD
is
equivalent
to
the
reference
dose
(
RfD)
divided
by
the
special
Food
Quality
Protection
Act
(
FQPA)
Safety
Factor.

For
chronic
exposures,
HED
is
concerned
when
estimated
dietary
risk
exceeds
100%
of
the
cPAD.

the

assessment

The

assessment
for
quinoxyfen
was
conducted
by
Jennifer
Tyler
(
03/

2003,
DP285313)
to
support
the
first
food
uses
of
quinoxyfen
(
cherries,
grapes
and
hops).
A
subsequent
assessment
to
support
the
FIFRA
§

uses
on
melons,
pumpkins
and
winter
squash
was
conducted
by
the

Food
Residue
Information
Residues
of
Concern:
Based
on
the
previously
submitted
cucumber,
grape,
sugar
beet
and
tomato
metabolism
studies,
the
nature
of
the
residue
in
plants
is
adequately
understood.
The
residue
of
concern
for
tolerance
and
risk
assessment
purposes
is
quinoxyfen,
per
se.

Tolerances:
Permanent
tolerances
have
been
established
under
40
CFR
§
180.588(
a)
for
residues
of
quinoxyfen,
5,7­
dichloro­
4­(
4­
fluorophenoxy)
quinoline,
in
or
on
cherry
(
sweet
and
tart)
at
0.3
ppm,
dried
hop
cones
at
3.0
ppm
and
grape
at
0.6
ppm.
Time­
limited
tolerances
for
residues
of
quinoxyfen
have
been
established
on
pumpkin,
winter
squash
and
melons
(
cucurbit
vegetable
subgroup
9A)
at
0.3
ppm
in
connection
with
FIFRA
§
18
emergency
exemptions.
These
timelimited
tolerances
expire
on
12/
31/
2007.

IR­

has
proposed
new
tolerances
for
residues
of
quinoxyfen
in
or
on
the
following
commodities:
pepper,
bell;
pepper,
non­
bell;
eggplant;
sub­

(
melon);
lettuce,
leaf;
lettuce,

and
strawberry.
HED
has
reviewed
residue
data
submitted
to
support
these
tolerances
and
concluded
that
the
following
tolerances
are
appropriate
[

used

The

assumed
that
quinoxyfen
residues
are
present
in
all
commodities
at
established
or,
for
the

tolerance
levels
and
that
100%

default
processing
factors
were
used
to
estimate
residues
in
cherry
juice,
grape
juice
and
raisins.

The
recommended
permanent
tolerance
for
melons
of
0.08
ppm
was
used
instead
of
the
higher,
time­
limited
tolerance
of
0.3
ppm,
since
HED
is
recommending
that
the
time­
limited
tolerance
be
revoked
concurrent
with
the
establishment
of
the
permanent
tolerance
for
melons.

The
proposed
use
of
quinoxyfen
on
eggplant
was
not
considered
in
this
assessment,
since
additional
data
are
required
and
HED
is
not
recommending
that
a
tolerance
be
established
at
this
time.

was
completed
in
August

In

Information
A
quinoxyfen

was
conducted
using
the
Dietary

Model
software
with
the
Food
Commodity
Intake
Database
(
DEEM­
FCID
 
,
Version
2.03),
which
incorporates

data
from
USDA's
Continuing
Surveys
of
Food
Intakes
by
Individuals
(
CSFII),
1994­
1996
and
1998.
The
1994­
96,

data
are
based
on
the
reported
consumption
of
more
than
20,000
individuals
over
two
non­

survey
days.
Foods

For

into

and

respondents,
HED
concluded
that
it
is
most
appropriate
to
report
risk
for
the
following
population
subgroups:
the
general
U.
S.
population,
all
infants
(<
1

children

13­
19,
adults
20­
49,
females
13­
49,
and
adults
50+
years
old.

For
chronic
dietary
exposure
assessments,
an
estimate
of
the
residue
level
in
each
food
or
foodform
(
e.
g.,
orange
or
orange
juice)
on
the
food
commodity
residue
list
is
multiplied
by
the
average
daily
consumption
estimate
for
that
food/
food
form
to
produce
a
residue
intake
estimate.
The
resulting
residue
intake
estimate
for
each
food/
food
form
is
summed
with
the
residue
intake
estimates
for
all
other
food/
food
forms
on
the
commodity
residue
list
to
arrive
at
the
total
average
estimated
exposure.
Exposure
is
expressed
in
mg/
kg
body
weight/
day
and
as
a
percent
of
the
cPAD.
This
procedure
is
performed
for
each

Results/
Discussion
As
stated
above,
for
chronic
assessments,
HED
is
concerned
when
dietary
risk
exceeds
100%
of
the
cPAD.
The
DEEM­
FCID
 
analyses
estimate
the
dietary
exposure
of
the
U.
S.
population
and
various
population
subgroups.
The
results
reported
in
Table

are
for
the
general
U.

Population,
all

Quinoxyfen
chronic
dietary
(

exposure
estimates
using
the
DEEM­

software
are
well
below
HED's
level
of
concern
for
the
U.
S.
population
and
each
of
the
population
subgroups.
Dietary
exposure
was
estimated
at
0.002596
mg/

day
for
the
U.

population
(
1.3%

and

(
2.0%
of
the
cPAD)
for
the
most
highly
exposed
population
subgroup
(
children,
1­

The
estimated
exposures/

for

and

are
summarized
in

1The
population
subgroup
with
the
highest
estimated
chronic
dietary
(
food
+
drinking
water)
exposure
and
risk
is
indicated
by
bold
text.

VII.
Characterization
of
Inputs/
Outputs
These
chronic
dietary
exposure
and
risk
estimates
are
conservative
since
they
assume
that
100%
of
crops
are
treated
with
quinoxyfen
and
that
residues
are
present
at
tolerance
levels.
In
addition,
drinking
water
exposure
estimates
were
based
on
screening
level
estimates
generated
by
the
PRZM­
EXAMS
model.
Dietary
exposure
estimates
could
be
refined
through
the
use
of
anticipated
residues
and
percent
crop
treated
data,
as
well
as
refined
estimated

water

concentrations.
However,
since
estimated
exposures
and
risks
using
conservative
assumptions
are
well
below
HED's
level
of
concern,
such
refinement
is
not
warranted.

VIII.
Conclusions
This
Tier
1
chronic
dietary
exposure
analysis
using
DEEM­
FCID
 
indicates
that
chronic
dietary
exposure
to
quinoxyfen
from
food
and
drinking
water
is
well
below
HED's
level
of
concern
for
this
pesticide.
Estimated
chronic
dietary
exposures
are
less
than
or
equal
to
2%
of
the
cPAD
for
the
general
U.
S.
population
and
all
population
subgroups.
