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).   This dietary survey was conducted from 2003 to 2008.  The analyses were performed to support the Section 3 registration on Rapeseed Crop Subgroup 20A of the fungicide difenoconazole [1-[2-[2-chloro-4-(4-chlorophenoxy)phenyl]-4-methyl-1,3-dioxolan-2-ylmethyl]-1H-1,2,4-triazole] and the use of difenoconazole on imported dragonfruit.

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 for the majority of 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 exposure estimates were less than HED's level of concern ( - <100% of the acute population-adjusted dose (aPAD)) at the 95[th] percentile of the exposure distribution for the general U.S. population (12 % aPAD) and all population sub-groups; the most highly exposed population subgroup was children1-2 years old with 27 % aPAD.  The resulting chronic food plus water exposure estimates were less than HED's level of concern ( - <100% of the chronic population-adjusted dose (cPAD)) for the general U.S. population (30 % cPAD) and all population sub-groups; the most highly exposed population subgroup was children 1 - 2 years old with 75 % 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 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.  HED is generally concerned when estimated cancer risk exceeds one in one million.  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:  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 (30-May-2012; DP#397664).

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.

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 updated.

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 for the majority of 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.

Almond: Field trial residues were used from MRID 47586101.

Apple: Field trial residues were used from MRID 46950233.

Broccoli: Field trial residues were used from MRID 47586102.  Residues from 1-7 day PHI were used since registered labels allow from 1-7 day PHIs.

Cabbage:  Field trial residues were used from 47586102.  Residues from 1-7 day PHI were used since registered labels allow from 1-7 day PHIs.  To refine the dietary exposure data from only cabbage samples without wrapper leaves were used.

Cantaloupe: Field trial residues were used from MRID 47586103.  Residues from 0-1 day PHI were used since registered labels allow from 0-1 day PHI.

Carrot: Field trial residues were used from MRID 47929804.

Chickpea: Field trial residues were used from MRID 47929805.

Cucumber: Field trial residues were used from MRID 47586103.  Residues from 0-1 day PHI were used since registered labels allow from 0-1 day PHI.

III.  Percent Crop Treated Information

The acute and chronic dietary exposure analyses assumed 100% crop treated (CT).

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, 14-August-2013; D412614).  For surface water, the EDWCs for canola/ oilseed subgroup 20A did not exceed the peak (acute) concentration of 17.4 ug/L, annual mean (non-cancer chronic) concentration of 11.8 ug/L and the 30 year annual average concentration (cancer chronic) of 8.6 ug/L for use on grape reported in the previous drinking water assessment (US EPA, 2012b; DP 398836 ). Therefore, the EDWCs for surface water for canola/ oilseed subgroup 20A (Table 1) did not supersede the previously recommended drinking water concentrations.  However, the previously recommended EDWCs were based on 0.87 PCA (Percent Cropped Area) factor. Recently, EFED implemented a revised guidance for PCA (USEPA 2012a). Since difenoconazole can be used in both non-agricultural (turf) and various agricultural crops, a PCA of 1.0 factor was used to revise previously recommended EDWCs for grape. For surface water, revised recommended EDWCs are 20.0 ug/L for peak, 13.6 ug/L for annual mean and 9.9ug/L for annual average concentrations
Estimated PZRM-GW ground water acute concentration of 2.24 ug/L and chronic concentration of 0.82 ug/L are higher than the previously recommended concentration of 1.30x 10[-2] ug/L for citrus (US EPA, 2011; D395784). Therefore, the current EDWCs superseded the previously recommended EDWCs for groundwater.  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(TM), 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.

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 95[th] percentile of the exposure distribution for general US population (11 % aPAD) and all population sub-groups; the most highly exposed population subgroup was Children 1-2 years old with 29 % aPAD.  The resulting chronic food exposure estimates were less than HED's level of concern ( - <100% cPAD) for the general U.S. population (27 % cPAD) and all population sub-groups; the most highly exposed population subgroup was children 1-2 years old with 78 % 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 for the majority of commodities, 100 % CT, and empirical or DEEM default processing factors.  Therefore, these analyses are considered conservative.  While they could be significantly 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 (ver. 2.03) 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 for the majority of commodities, 100 % 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 subgroups in the acute (at the 95[th] percentile of the exposure distribution) and chronic analyses were Children 1-2 years old (29 % aPAD) and children 1-2 years old (78 % cPAD), respectively.
