Executive Summary

Difenoconazole acute and chronic dietary exposure and risk assessments
were conducted using the Dietary Exposure Evaluation Model software with
the Food Commodity Intake Database (DEEM-FCID) Version 3.16.  This
software uses 2003-2008 food consumption data from the U.S. Department
of Agriculture’s (USDA’s) National Health and Nutrition Examination
Survey, What We Eat in America, (NHANES/WWEIA).   The analyses were
performed to support the Section 3 registration on Pea and Bean, Dried
Shelled, Except Soybean, Subgroup 6C and Bushberry Subgroup 13-07B of
the fungicide difenoconazole [1-[2-[2-chloro-4-(4-chlorophenoxy)
phenyl]-4-methyl-1,3-dioxolan-2-ylmethyl]-1H-1,2,4-triazole].  In
addition, these analyses were performed to support the amended use of
difenoconazole for post-harvest use on pome fruit.  

This memorandum was reviewed by two peer reviewers of the DESAC, per
DESAC SOP 2012.1. 

The unrefined acute analysis assumed tolerance-level residues, 100% crop
treated (CT), and the available empirical or DEEM (ver. 7.81) default
processing factors.  The somewhat refined chronic analysis assumed
tolerance-level residues for some commodities, average field trial
residues and USDA Pesticide Data Program monitoring samples for the
remaining commodities, the available empirical or DEEM (ver. 7.81)
default processing factors, and 100% CT.  The EDWC of 20.0 μg/L (ppb)
was used for the acute dietary exposure analysis and an estimated
drinking water concentrations (EDWC) of 13.6 μg/L (ppb) was used for
the chronic dietary exposure analysis.

The resulting acute food plus water dietary exposure estimates were less
than HED’s level of concern (<100% of the acute population-adjusted
dose (aPAD)) at the 95th percentile of the exposure distribution for the
general U.S. population (15% aPAD) and all population sub-groups; the
most highly exposed population subgroup was children 1-2 years old with
49% aPAD.  The resulting chronic food plus water dietary exposure
estimates were less than HED’s level of concern (<100% of the chronic
population-adjusted dose (cPAD)) for the general U.S. population (26%
cPAD) and all population sub-groups; the most highly exposed population
subgroup was children 1 - 2 years old with 88% cPAD.  No cancer analysis
was performed since it was determined the chronic dietary exposure
assessment is protective of cancer effects. 

The dietary exposure analyses for the triazole metabolites were
previously updated (D414951, T. Morton, 24 Oct. 2013).

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 PAD.  The PAD is equivalent
to the point of departure (POD, NOAEL, LOAEL, e.g.) divided by the
required uncertainty or safety factors.

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,” 21-JUN-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 (20-AUG-1999).

The most recent dietary risk assessment for difenoconazole was conducted
by T. Morton (15-January-2015; DP#412812).

II.   Residue Information

Difenoconazole tolerances are published in 40 CFR§180.475.

Residues of Concern in Plants and Livestock:   

Residues of concern were determined based on recommendations from the
HED Residues of Concern Knowledgebase Sub-committee (ROCKS) (D391350,
9/19/11).  The residue of concern for plant commodities for tolerance
expression and risk assessment purposes is difenoconazole per se.  The
HED ROCKS has determined that the parent compound and the CGA-205375
metabolite are the residues of concern in livestock commodities for both
the tolerance expression and the risk assessment. In addition,
metabolite OH-CGA-169374, which comprised 15% of the TRR in goat milk
from the phenyl-labeled study, should be considered as a residue of
concern for the dietary risk assessment.  Based on available goat
metabolism data, total residues of concern in milk for dietary risk
assessments (parent, CGA-205375, and OH-CGA-169374), should be
calculated by multiplying the tolerance in milk by a factor of 1.5x. 
Table 1 summarizes tolerance expression and the residues of concern in
plant and livestock commodities.

Table 1.  Difenoconazole Residues of Concern in Plants and Ruminants.

Matrix	Residues of Concern

Livestock	Ruminant and Poultry	Parent and CGA 205375	Parent and CGA
205375

	Milk	Parent, CGA 205375, and OH-CGA-169374	Parent and CGA 205375

Drinking Water	Parent Only	NA

Note:  The triazole-containing metabolites 1,2,4-T, TA, and TAA should
be included in the residues of concern for risk assessment purposes only
for plant and livestock commodities.  Since these metabolites are common
to the entire class of traizole-derivative fungicides and because of
differential toxicity between metabolites and the various parent
compounds, risks associated with exposure to 1,2,4-T and to TA/TAA are
addressed separately.

Recommended Tolerances:  Based on the residue chemistry data submitted
with the previous petitions, HED recommended for establishment of the
new food tolerances (DP# 412810, B. Cropp-Kohlligian, 22-August-2013). 
The recommended, established, and revised tolerances are listed in Table
2 below.

The dietary exposure analyses for the triazole metabolites (D414951, T.
Morton, 24 Oct. 2013) was previously updated.  Addition of these uses
did not significantly change the dietary exposure for the triazole
metabolites.

Food Residues and processing factors used in the Acute and Chronic
Analysis:  The acute analysis assumed tolerance-level residues and 100%
CT for all the registered and proposed crops. Tolerance-level residues
were also assumed for all livestock tissues in this assessment.  The
chronic analysis assumed tolerance-level residues for some commodities,
average field trial residues and USDA PDP average residues for the
remaining commodities, and 100 % CT.  Those commodities where field
trial data were used are summarized below.  HED SOP 2000.1 Guidance for
Translation of Field Trial Data from Representative Commodities in the
Crop Group Regulation to Other Commodities in Each Crop Group/Subgroup
dated 9/12/2000 was used in translating to other commodities in the crop
group.  Experimental processing factors were used for apple juice
(0.04x), grape juice (0.2x), citrus juices (0.1x), potato chips (0.5x),
potato granules/flakes (0.5x), raisin (3.5x chronic only since the
raisin tolerance was used in acute), sugar beet molasses (0.6x), tomato
paste (1.6x), and tomato puree (0.5x); DEEM (ver. 7.81) default
processing factors were assumed for other processed commodities.

III.  Percent Crop Treated Information

The acute dietary exposure analyses assumed 100% crop treated (CT). 
Average %CT was used for the following crops:  almond 5%, cabbage 2.5%,
cucumbers 5%, garlic 5%, grape 5%, grapefruit 2.5%, onions 5%, orange
2.5%, pecan 2.5%, peach 1%, peppers 2.5%, pistachio 2.5%, pumpkin 2.5%,
squash 5%, strawberry 2.5%, sugar beets 15%, tangerine 2.5%, tomatoes
25%, walnut 2.5%, watermelon 5%, and wheat 10%.

IV.  Drinking Water Data

The drinking water estimates used in the dietary risk assessment were
provided by the Environmental Fate and Effects Division (EFED; Memo, F.
Khan, 13-November-2014; D421092).  The EDWCs for surface water for the
requested new uses did not supersede the previously recommended drinking
water concentrations.  For surface water, revised recommended EDWCs are
20.0 µg/L for peak, 13.6 µg/L for annual mean and 9.9µg/L for annual
average concentrations  Recommended EDWCs for human health are 20.0
μg/L (ppb) for the acute dietary (food plus water) exposure analysis
and the 1-in-10 year annual mean EDWC of 13.6 μg/L (ppb) for the
chronic dietary (food plus water) exposure analysis.

V.  DEEM-FCID Program and Consumption Information

Difenoconazole acute and chronic dietary exposure assessments were
conducted using the Dietary Exposure Evaluation Model software with the
Food Commodity Intake Database DEEM-FCID, Version 3.16, which
incorporates consumption data from USDA’s National Health and
Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). 
This dietary survey was conducted from 2003 to 2008.  The 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 2003-2008 WWEIA
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 50-99 years old.

For chronic dietary exposure assessment, 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.  The resulting residue
consumption estimate for each food/food form is summed with the residue
consumption 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., 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,
significant differences in user vs. per capita exposure and risk are
identified and noted in the risk assessment.

VI.  Toxicological Information

On 08-SEP-1998, HED’s Hazard Identification Assessment Review
Committee (HIARC) evaluated the toxicology database of difenoconazole
and re-assessed the RfD established in 1994, as well as the
toxicological endpoints for the dietary and occupational exposure risk
assessments that were selected in 1994.  At this meeting, the HIARC also
addressed the potential enhanced sensitivity of infants and children
from exposure to difenoconazole as required by the Food Quality
Protection Act (FQPA) of 1996 (HED Doc. No. 012873, 25-SEP-1998).  In
July, 2007, the RAB1 toxicologists and risk assessment team met to
reevaluate the endpoints selected by the HIARC since new studies were
submitted.  RAB1 toxicologists and risk assessment team also reevaluated
FQPA assessments.  The risk assessment team concluded that the default
10x FQPA Safety Factor (SF) should be reduced to 1x when assessing acute
and chronic dietary exposures (M.Sahafeyan, D333320, 09-AUG-07).  The
relevant endpoints are shown in Table 3.

In accordance with HED’s current policy and EPA’s 2005 Cancer
Guidelines, difenoconazole is classified as “Suggestive Evidence of
Carcinogenic Potential,” based on excessive toxicity observed at the
two highest doses, the absence of tumors at the lower doses and the
absence of genotoxic effects.   A margin-of-exposure (MOE) approach in
risk assessment was advocated by HED’s  CPRC in 1994.  Use of an MOE
approach was reviewed and reaffirmed in 2007 by the CPRC Chair (PV Shah,
3/1/07, HED Doc. No. 0054532).  Therefore, a separate cancer dietary
assessment is not being conducted for difenoconazole.

Table 3.  Summary of Toxicological Doses and Endpoints for
Difenoconazole for Use in Dietary Risk Assessments.  

Exposure Scenario	Point of Departure	Uncertainty/FQPA Safety Factors
RfD, PAD, for Risk Assessment	Study and Relevant Toxicological Effects

Acute Dietary (All populations)	NOAEL = 25

mg/kg	UFA = 10X

UFH = 10X

FQPA SF = 1X 	aRfD = aPAD = 0.25 mg/kg/day	Acute Neurotoxicity Study in
Rats

LOAEL= 200 mg/kg in males based on reduced fore-limb grip strength in
males on day 1.

Chronic Dietary (All populations)	NOAEL = 0.96

mg/kg/day	UFA = 10X

UFH = 10X

FQPA SF = 1X	cRfD = cPAD = 0.01mg/kg/day	Combined chronic
toxicity/carcinogenicity (rat; dietary) LOAEL = 24.1/32.8 mg/kg/day
(M/F) based on cumulative decreases in body-weight gains.

Cancer (oral, dermal, inhalation)	Difenoconazole is classified as a
Group C, possible human carcinogen with a non-linear (MOE) approach for
human risk characterization (CPRC Document, 7/27/94, Memo, P. V. Shah
dated March 3, 2007, HED Doc. No. 0054532). The chronic dietary exposure
assessment is protective of cancer effects.

Point of Departure (POD) = A data point or an estimated point that is
derived from observed dose-response data and  used to mark the beginning
of extrapolation to determine risk associated with lower environmentally
relevant human exposures.  NOAEL = no observed adverse effect level. 
LOAEL = lowest observed adverse effect level.  UF = uncertainty factor. 
UFA = extrapolation from animal to human (interspecies).  UFH =
potential variation in sensitivity among members of the human population
(intraspecies).  FQPA SF = FQPA Safety Factor.  PAD = population
adjusted dose (a = acute, c = chronic).  RfD = reference dose.   

VII.  Results/Discussion

As stated above, for acute and chronic assessments, HED is concerned
when dietary risk exceeds 100% of the aPAD or cPAD, respectively.  The
following paragraphs are summaries of the DEEM-FCID (ver. 2.03) acute
and chronic exposure analyses.

Acute and chronic aggregate (food + water) analyses were performed using
DEEM-FCID estimating the dietary exposure of the U.S. population and
various population subgroups.  The results are summarized in Tables 4
and 5 below for acute and chronic analyses respectively.  

The resulting acute food exposure estimates were less than HED’s level
of concern (<100% aPAD) at the 95th percentile of the exposure
distribution for general US population (15 % aPAD) and all population
sub-groups; the most highly exposed population subgroup was All Infants
<1 year old with 49 % aPAD.  The resulting chronic food exposure
estimates were less than HED’s level of concern (<100% cPAD) for the
general U.S. population (26 % cPAD) and all population sub-groups; the
most highly exposed population subgroup was children 1-2 years old with
88 % cPAD.   A separate cancer dietary assessment was not conducted for
difenoconazole because the cancer NOAEL is higher than the chronic RfD;
therefore, the chronic dietary risk estimate is considered protective of
all chronic effects including carcinogenicity.

VIII.  Characterization of Inputs/Outputs

The acute analysis assumed tolerance-level residues, 100% CT, and
empirical or DEEM default processing factors.  The chronic analysis
assumed tolerance-level residues for some commodities, average field
trial residues and USDA PDP monitoring data for the remaining
commodities, average % CT, and empirical or DEEM default processing
factors.  Therefore, these analyses are considered refined.  While they
could be further refined, further refinement is not warranted as
estimated risks are not of concern.  

IX.  Conclusions

An acute aggregate (food + water) dietary risk assessment was conducted
for difenoconazole using the DEEM-FCID Model and assumed tolerance-level
residues, 100% CT, and empirical or DEEM default processing factors. 
The chronic aggregate dietary risk assessment assumed tolerance-level
residues for some commodities, average field trial residues and USDA PDP
monitoring data for the remaining commodities, average % CT, and
empirical or DEEM default processing factors.  The resulting acute and
chronic aggregate exposure estimates were less than HED’s level of
concern.  For the general U.S. population, the aPAD and cPAD were 11 %
and 27 %, respectively.  The most highly-exposed population subgroup in
the acute (at the 95th percentile of the exposure distribution) was All
Infants <1 year old (49 % aPAD) and chronic analysis were children 1-2
years old (88 % cPAD), respectively.

Attachment 5:  Percent Crop Treated Memorandum

Difenoconazole (128847)

Screening Level Usage Analysis (SLUA)

Date: October 2, 2014 

What is a Screening Level Usage Analysis (SLUA)?

Available estimates of pesticide usage data for a particular active
ingredient that is used on agricultural crops in the United States.

Pesticide usage data obtained from various sources.  The data are then
merged, averaged, and rounded so that the presented information is not
proprietary, business confidential, or trade secret. 

What does it contain?

Pesticide usage data for a single active ingredient only.

Agricultural use sites (crops) that the pesticide is reported to be used
on. 

Available pesticide usage information from U.S. states that produce 80%
or more of a crop, in most cases, or less than 80%, in rare cases,
depending on the scope of the survey and available resources.

Annual percent of crop treated (average & maximum) for each agricultural
crop.

Average annual pounds of the pesticide applied for each agricultural
crop (i.e., for the states surveyed, not for the entire United States).

What assumptions can I make about the reported data?

Average pounds of active ingredient applied - Values are calculated by
merging pesticide usage data sources together; averaging across all
observations, then rounding.  Note:  If the estimated value is less than
500, then that value is labeled <500.  Estimated values between 500 &
<1,000,000 are rounded to 1 significant digit.  Estimated values of
1,000,000 or greater are rounded to 2 significant digits.)

Average percent of crop treated - Values are calculated by merging data
sources together; averaging by year, averaging across all years, &
rounding to the nearest multiple of 5.  Note:  If the estimated value is
less than 2.5, then the value is labeled <2.5.  If the estimated value
is less than 1, then the value is labeled <1.

Maximum percent of crop treated - Value is the single maximum value
reported across all data sources, across all years, & rounded up to the
nearest multiple of 5.  Note:  If the estimated value is less than 2.5,
then the value is labeled <2.5.

What are the data sources used?

USDA-NASS (United States Department of Agriculture’s National
Agricultural Statistics Service) – pesticide usage data from 2004 to
2012.

Private pesticide market research – pesticide usage data from 2004 to
2012.

California Department of Pesticide Regulation (DPR) Pesticide Use
Reporting (PUR) data for 2004 to 2011.

What are the limitations to the data?

Additional registered uses may exist but are not included because the
available surveys do not report usage (e.g., small acreage crops).

Lack of reported usage data for the pesticide on a crop does not imply
zero usage.

Usage data on a particular site may be noted in data sources, but not
quantified.  In these instances, the site would not be reported in the
SLUA.

Non-agricultural use sites (e.g., turf, post-harvest, mosquito control,
etc.) are not reported in the SLUA.  A separate request must be made to
receive these estimates.

Some sites show some use, even though they are not on the label.  This
usage could be due to various factors, including, but not limited to
Section 18 requests, existing stocks of the chemical, data collection
errors, and experimental use permits (EUPs).
