Executive Summary

ion 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 analyses
were performed to support the proposed IR-4 tolerance petitions for the
use of cymoxanil on grapes, hops and caneberries.

The unrefined acute analysis (females 13-49 years old only) assumed that
cymoxanil residues are present in all registered food commodities at
tolerance levels and that 100% of all commodities are treated.  DEEM
version 7.81 default processing factors were used for all registered and
proposed commodities except for grape juice and raisins where the
default concentration factors were set to 1 (see memo S. Chun; DP Num:
248603; 02/SEPT/1998). For risk assessment purposes for lettuce and
hops, the metabolite IN-KQ960 was included, along with the parent, based
on the ratio of IN-KQ960 to the parent (3.5) in the lettuce metabolism
study (i.e., the recommended tolerance level was multiplied by 3.5 to
account for IN-KQ960).  

The partially refined chronic analysis was conducted for the general
U.S. population and all population subgroups using mean tolerance level
residues for all commodities except lettuce and residues for lettuce
field trials conducted at the highest application rate (1.3125 lb. ai/A)
(MRID 44946430, S. Levy, 20/NOV/2002). Exposure estimates were further
refined based on screening-level percent crop treated (% CT) data for
several registered commodities and projected % crop treated data for
grapes.  

Drinking water was incorporated directly into the dietary assessment
using the estimated drinking water concentrations (EDWC).  EDWCs were
generated using the FIRST (version 1.0) model for surface water.  For
the acute assessment, a concentration of 0.019 ppm was used; for the
chronic assessment, the value of 0.0001 ppm was used.

Acute Dietary Exposure Results

The unrefined acute dietary exposure assessment was performed for
females 13-49 years old only, since an acute endpoint of concern was not
identified for the general U.S. population.  Based on the assumptions
described above, acute dietary exposure of females 13-49 years old is
below ARIA’s level of concern at the 95th percentile of exposure. 
Combined dietary exposure from food and drinking water is estimated at
0.028791 mg/kg/day, equivalent to 72 % of the acute Population Adjusted
Dose (aPAD).

Chronic Dietary Exposure Results 

™ software, dietary exposure is estimated at 0.000414 mg/kg/day for
the general U.S. population (52% of the chronic Population Adjusted Dose
(cPAD)) and 0.000560 mg/kg/day (70% of the cPAD) for adults 20-49 years,
the population subgroup with the highest estimated chronic dietary
exposure to cymoxanil.  

I.	Introduction

Dietary risk assessment incorporates both exposure and toxicity of a
given pesticide.  For acute and 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 acute and non-cancer chronic exposures, HED is concerned when
estimated dietary risk exceeds 100% of the PAD.  References which
discuss the acute and chronic risk assessments in more detail are
available on the EPA/pesticides web site:  “Available Information on
Assessing Exposure from Pesticides, A User’s Guide,” 6/21/2000, web
link:      HYPERLINK
"http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf" 
http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf  ; or see
SOP 99.6 (8/20/99).

The most recent HED dietary risk assessment for cymoxanil (S. Levy, DP
Num: 276292, 04/DEC/2002) was conducted to support the FIFRA §3 food
uses on hops, lychee, fruiting vegetables, head lettuce and cucurbits.
The current assessment incorporates drinking water directly into the
dietary analyses using the EDWCs calculated for the proposed tolerances
on grapes, hops and caneberries. 

Food Residue Information

A. Tolerance Expression and Residues of Concern for the
Registered/Proposed Crops

An ad hoc MARC met on 21/JAN/1998 and decided that parent only is of
regulatory concern (G. Kramer, et. al., DP Num: 242321, 26/JAN/1998) in
tomatoes, potatoes, grapes, livestock, rotational crops and drinking
water. Subsequent to the initial MARC meeting, the petitioner submitted
a lettuce metabolism study (MRID 44944605). Metabolites IN-KQ960 and
IN-KP533 are present in the lettuce metabolism study which were not
present in the tomato, grape, potato or rat metabolism studies. The
lettuce metabolism results were presented to the HED MARC to assess the
toxicological significance of these metabolites and to determine which
additional residues, if any, to regulate in lettuce. 

The MARC concluded (S. Levy, DP Num: 276796, 30/AUG/2001) that for the
tolerance expression the residue of concern in/on hops is cymoxanil per
se. For risk assessment purposes for hops and lettuce, the metabolite
IN-KQ960 must be included, along with the parent, based on the ratio of
IN-KQ960 to the parent in the lettuce 14C metabolism study. For any
future petitions for tolerance on leafy vegetables, the petitioner was
instructed to include residue data for IN-KQ960. The final decision
concerning the tolerance expression in lettuce and other leafy
vegetables is deferred pending results of the residue studies. 

Tolerances are currently established under 40 CFR 180.503 for grape (0.1
ppm, imports only), hop, dried cones (1.0 ppm), lettuce, head (4.0 ppm),
lychee (1.0 ppm), potato, (0.05 ppm), vegetable, cucurbit, group 9 (0.05
ppm) and vegetable, fruiting, group 8 (0.2 ppm). IR-4 has proposed
adding caneberries (4 ppm) and increasing the grape tolerance to 1 ppm
and the dried hop tolerance to 5 ppm. The increased tolerance for grapes
is being requested to support domestic use of cymoxanil on grapes. The
increased tolerance for dried hop is being requested to support a
different formulation which results in higher field trials. ARIA has
reviewed the residue chemistry data associated with the current request.
These data do not support increasing the tolerance for grapes from 0.1
to 1.0 ppm.  The data indicate that the tolerance for hop should be
increased from 1.0 to 7.0 ppm. ARIA concludes that the following
tolerances for residues of cymoxanil are appropriate (D. Rate, DP Num:
324447)

Grape 			0.1 ppm

Hop, dried cones	7.0 ppm  

Caneberries		4.0 ppm          

B. Residue Data used in the Acute and Chronic Dietary Analyses

Acute:  Tolerance level residues and 100% CT were assumed for all plant
commodities. DEEM (ver.7.81) default processing factors were assumed for
all registered and proposed commodities except for grape juice and
raisins where the default concentration factors were set to 1 (see S.
Chun, DP Num: 248603, 02/SEPT/1998 for details). For risk assessment
purposes for lettuce and hops, the metabolite IN-KQ960 was included,
along with the parent, based on the ratio of IN-KQ960 to the parent
(3.5) in the lettuce metabolism study (i.e., the recommended tolerance
level was multiplied by 3.5 to account for IN-KQ960).

Chronic:

The partially refined chronic dietary exposure analysis incorporated
mean field trial residues of cymoxanil for lettuce (with wrapper leaves)
from trials conducted at the highest application rate (1.3125 lb. ai/A)
(MRID 44946430, S. Levy, 20/NOV/2002).  Tolerance level residues were
used for all other commodities. Exposure estimates were further refined
based on screening-level percent crop treated (% CT) data provided by
BEAD for cucumbers, lettuce, peppers, potatoes, pumpkins, squash,
tomatoes and watermelons [Cymoxanil Screening- level Usage Analysis
(SLUA),  J. Carter, 02/NOV/2006].  A conservative projected % crop
treated estimate of 10% was used for grapes. Cymoxanil is proposed for
use only on grapes grown east of the Rocky Mountains. USDA production
statistics for grapes indicate that in 2003, 2004 and 2005 more than 93%
of U.S. grapes were produced in two West Coast states (California and
Washington) [USDA NASS Non-Citrus Fruits and Nuts; 2005 Summary; FrNt
1-3 (06)].  Therefore, ARIA conservatively estimates that even if all of
the grapes grown east of the Rockies were treated with cymoxanil, less
than 10% of the grapes would be treated.

Caneberries: DW Assessment; D.Young and T. Steeger,  21/SEPT/2006, DP
Num: 331978

The Environmental Fate and Effects Division (EFED) calculated screening
level surface water and ground water estimates for cymoxanil using FIRST
(version 1.0) model and the SCI-GROW model, respectively. The drinking
water models and their descriptions are available at the EPA internet
site:   HYPERLINK "http://www.epa.gov/oppefed1/models/water/" 
http://www.epa.gov/oppefed1/models/water/ .  The newly proposed
application rate for caneberries is less than the rates evaluated for
the new use of cymoxanil on grapes and hops. Therefore no new drinking
water concentrations are needed for the proposed use. The newly proposed
application rates for use on grapes and hops are higher than the rates
evaluated in the previous Section 3 registration for the use of
cymoxanil on potatoes (DP Num: 233366) and for the initial IR-4
tolerance petition for use of cymoxanil (Curzate 60 DF) on hops (DP Num:
271572).  Therefore new drinking water concentrations were determined
for the proposed uses. Tier 1 drinking water concentrations (EDWCs)
based on the newly proposed application rate for grapes appear in Table
3 as follows:

Table #3.  Estimated drinking water concentrations for Cymoxanil1

	Acute  (ppm)	Chronic  (ppm)

Groundwater	0.000003	0.000003

Surface Water	0.019	0.0001

1 Concentrations determined from the grape application (0.25 lbs per
acre, 10 times), which was the highest application rate reported for the
new proposed uses.

For the purpose of these dietary assessments, ARIA used 0. 019 ppm for
the acute analysis and 0.0001 ppm for the chronic analysis.  For both
the acute and chronic analyses, the drinking water EDWC was incorporated
directly as a point estimate in the

IV.	DEEM-FCID™ Program and Consumption Information

Cymoxanil acute and chronic dietary exposure assessments were conducted
using the Dietary Exposure Evaluation Model software with the Food
Commodity Intake Database (DEEM-FCID™, Version 2.03), which
incorporates consumption data from USDA’s Continuing Surveys of Food
Intakes by Individuals (CSFII), 1994-1996 and 1998.  The 1994-96, 98
data are based on the reported consumption of more than 20,000
individuals over two non-consecutive survey days.  Foods “as
consumed” (e.g., apple pie) are linked to EPA-defined food commodities
(e.g. apples, peeled fruit - cooked; fresh or N/S; baked; or wheat flour
- cooked; fresh or N/S, baked) using publicly available recipe
translation files developed jointly by USDA/ARS and EPA.  For chronic
exposure assessment, consumption data are averaged for the entire U.S.
population and within population subgroups, but for acute exposure
assessment are retained as individual consumption events.  Based on
analysis of the 1994-96, 98 CSFII consumption data, which took into
account dietary patterns and survey respondents, HED concluded that it
is most appropriate to report risk for the following population
subgroups: the general U.S. population, all infants (<1 year old),
children 1-2, children 3-5, children 6-12, youth 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 food-form (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
population subgroup.

For acute exposure assessments, individual one-day food consumption data
are used on an individual-by-individual basis.  The reported consumption
amounts of each food item can be multiplied by a residue point estimate
and summed to obtain a total daily pesticide exposure for a
deterministic exposure assessment, or “matched” in multiple random
pairings with residue values and then summed in a probabilistic
assessment.  The resulting distribution of exposures is expressed as a
percentage of the aPAD on both a user (i.e., only those who reported
eating relevant commodities/food forms) and a per-capita (i.e., those
who reported eating the relevant commodities as well as those who did
not) basis.  In accordance with HED policy, per capita exposure and risk
are reported for all tiers of analysis.  However, for Tiers 1 and 2, any
significant differences in user vs. per capita exposure and risk are
specifically identified and noted in the risk assessment.

VI.	Results/Discussion 

As stated above, for acute and chronic assessments, ARIA is concerned
when dietary risk exceeds 100% of the PAD.  The DEEM-FCID™ analyses
estimate the dietary exposure of the U.S. population and various
population subgroups.  The acute exposure results are reported in Table
# 5 for females 13-49 only.  The chronic results reported in Table # 6
are for the general U.S. Population, all infants (<1 year old), children
1-2, children 3-5, children 6-12, youth 13-19, females 13-49, adults
20-49, and adults 50+ years.  

Results of Acute Dietary Exposure Analysis

The unrefined acute dietary (food + drinking water) exposure assessment
was performed for females 13-49 years old only, since an acute endpoint
of concern was not identified for the general population.  Based on the
assumptions described above in sections II and III, acute dietary
exposure of females 13-49 years old is below ARIA’s level of concern
(i.e., <100% of the aPAD of 0.04 mg/kg).  The combined dietary exposure
from food and drinking water is estimated at 0.028791 mg/kg/day (72% of
the aPAD), at the 95th percentile of exposure, the appropriate
regulatory statistic for Tier 1 dietary assessments.

U.S. population and each of the population subgroups.  Dietary exposure
was estimated at 0.000414 mg/kg/day for the U.S. population         (52%
of the cPAD) and 0.000560 mg/kg/day (70% of the cPAD) for the most
highly exposed population subgroup (adults 20-49 years).  The estimated
exposures/risks for food, drinking water and combined food and water are
summarized in Table # 6 for all populations.

(food + drinking water) exposure and risk is indicated by bold text.

VII.	Characterization of Inputs/Outputs

The acute dietary exposure and risk estimates are conservative since
they assume that 100% of crops are treated with cymoxanil and that
residues are present at tolerance levels.  In addition, drinking water
exposure estimates were based on screening level estimates generated by
the model.  Dietary exposure estimates could be refined through the use
of anticipated residues and percent crop treated data, as well as
refined estimated drinking water concentrations.  However, since
estimated exposures and risks using conservative assumptions are below
ARIA’s level of concern, such refinement is not warranted.

This chronic dietary exposure for cymoxanil is a partially refined
assessment which incorporates average field trial residues for lettuce,
a screening level % CT data for several registered commodities and
projected % CT for grapes.  Dietary exposure estimates could be further
refined through the use of additional anticipated residues as well as
refined EDWCs. As with the acute assessment, such refinements are not
warranted at this time. 

VIII.	Conclusions

The unrefined acute dietary exposure analysis using DEEM-FCID™
indicates that dietary exposures to cymoxanil from food and drinking
water are below ARIA’s level of concern for this pesticide.  The
estimated acute exposure of females 13-49 years old, the only population
subgroup of concern for acute exposure, represents 72% of the aPAD at
the 95th percentile of exposure.  

The partially refined chronic dietary exposure analysis using
DEEM-FCID™ indicates that dietary exposure to cymoxanil from food and
drinking water are below ARIA’s level of concern for this pesticide.
Estimated chronic dietary exposures are less than or equal to 70% of the
cPAD for the general U.S. population and all population subgroups.
