Executive Summary

Acute and chronic aggregate dietary (food and drinking water) 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 request for use on ginseng, succulent beans bulb onion (Subgroup 3-07A), and green onion (Subgroup 3-07B). 

Acute Dietary Exposure Assessment

 A slightly unrefined acute dietary risk assessment was conducted which used maximum field trial residue values, assumed 100 percent crop treated (% CT) for all commodities, incorporated DEEM(TM) default processing factors and empirical factors were used for processed commodities and included modeled drinking water estimates.  The estimated exposure (food and water) to the U.S. population from the existing and proposed new uses of fenamidone resulted in an estimated risk equivalent to 3% of the acute population adjusted dose (aPAD) at the 95[th] percentile.  The most highly exposed subpopulation was children 1 - 2 years with an estimated exposure equivalent to 5% of the aPAD at the 95[th] percentile.

Chronic Dietary Exposure Assessment

 A chronic dietary risk assessment was conducted which used maximum field trial residue values, assumed 100 % CT for all commodities, incorporated DEEM(TM) default processing factors for many processed commodities and included modeled drinking water estimates.  The estimated exposure (food and water) to the U.S. population from the existing and proposed new uses of fenamidone resulted in an estimated risk equivalent to 53% of the chronic population adjusted dose (cPAD).  The most highly exposed subpopulation was children 1  -  2 years with an estimated exposure equivalent to 89% of the cPAD.

Cancer Dietary Exposure Assessment 

Fenamidone is not likely to be a human carcinogen; therefore a cancer dietary risk assessment is not required for this chemical.  

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 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 In Food, A User's Guide," 5-NOV-2013, web link:  http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf ; or see SOP 99.6 (29-OCT-2013).

The most recent dietary risk assessment for fenamidone was conducted by Alexandra LaMay (D391040, 07/7/11).

II.  Residue Information

Tolerances are currently established for residues of fenamidone under 40 CFR 180.579 (a)(1)  for a variety of primary crops including bulb vegetables, cucurbit vegetables, tuberous and corm vegetables, brassica vegetables, leafy vegetables, fruiting vegetables, cotton, non bell pepper, sunflower, and tomato ranging from 0.02 ppm to 60 ppm.  Livestock commodity tolerances are established for residues of fenamidone and RPA 717879 (DADK-Fen) in milk, fat, meat and meat byproducts under 180.579(a)(2).  Rotational crop tolerances are established for residues of fenamidone and RPA 717870 (DADK-Fen) in wheat, corn and soybean commodities and strawberries ranging from 0.02 ppm to 0.50 ppm under 40CFR 180.579(d).

The residues of concern for tolerance setting and risk assessment purposes are summarized in the table below.

The tolerances are presented in the most recent residue chemistry document (K. Milians, D409835). 

The new residues were included in the acute and chronic dietary risk assessment and a description of how they were calculated are shown in Table 2.

Ginseng

                                     1.19

The field rotational crop studies monitored for residues of fenamidone and metabolites (RPA 717879, RPA 408056 and RPA 405862) in ginseng.  RPA 413255 is included as a residue of concern for ginseng since it is in the same crop group as carrot, however, this analyte was not determined in the field trials for ginseng. Data from carrot was used to estimate a factor to account for RPA 413255.  The carrot metabolism study (469291101.der.doc) indicated that residues of RPA 413255 were 0.6x that of fenamidone (D314318, T. Bloem, 7-Jun-2007). The ginseng field trials showed that residues of parent fenamidone were 0.35 ppm, conjugated RPA 408056 were 0.024 ppm, RPA 717879  were <0.02 and RPA 405862 were 0.022 for combined residues of 0.98 ppm (D409835, K. Milians).  Using the 0.6x factor to account for RPA 413255 the combined residue level would be 1.19 ppm (0.98 ppm + 0.35 ppm x 0.21ppm).
Snap Beans
                                     0.52
The field crop studies monitored for residues of fenamidone and metabolites (RPA 717879, RPA 408056 and RPA 405862) in snap beans.  Residues of fenamidone, RPA 405862, RPA 717879, RPA 408056 in snap beans were 0.46, 0.02, 0.02 and 0.02 ppm, respectively, for a total residue of 0.52 ppm (MRID 49052103; D409835, K. Milians).

DEEM (ver. 7.81) default processing factors were maintained for all commodities excluding grape juice, dried potato, tomato paste, tomato puree, field corn processed commodities and soybean processed commodities.  For these commodities, the DEEM (ver. 7.81) default processing factors were reduced to 1 based on processing data (grape), were reduced to 1 based on the application of empirical processing factors to the RAC residue (tomato paste, tomato puree, and dried potato; D277818, T. Bloem, 4/22/04), or were reduced to 1 based on lack of residues at exaggerated rates in the RAC (field corn processed commodities and soybean processed commodities; D357372, A. LaMay, 2/24/09).

III.  Percent Crop Treated Information

For all commodities 100 percent crop treated was assumed. 

IV. Drinking Water Data

The drinking water residues used in the dietary risk assessment were provided by the Environmental Fate and Effects Division (EFED, J. K. Wolf, D409837, 09/18/13) and were incorporated directly into the acute and chronic dietary assessments.  Water residues were incorporated in the DEEM-FCID into the food categories "water, direct, all sources" and "water, indirect, all sources."

Monitoring data are not available for residues of fenamidone and its metabolites in water; therefore EFED has provided modeled values for ground and surface water.  The modeled EDWCs (estimated drinking water concentrations) are reported for parent and its degradation products, RPA-412636, RPA-412108, RPA-411639, RPA-413255, RPA-409446, and RPA- 410995.  These are the residues of concern in drinking water, as determined by the Metabolite Assessment Committee (MARC, 05/25/04).  Surface water EDWCs were calculated using a Tier II model for surface water PRZM (Pesticide Root Zone Model, Version 3.122) and EXAMS (Version 2.98.04) using the PE5 platform.  The EDWC in ground water were estimated using the Screening Concentration In Ground Water model (SCI-GROW, Version 2.3) and PRZM-GW (Pesticide Root Zone Model for Groundwater, version 1.0, August 31, 2012). EDWCs in surface source water were corrected using the default percent crop area factor (0.91).  The default PCA was applied because fenamidone can be used on numerous crops.  No water treatment effects were considered in this assessment.  These models and their descriptions are available at the EPA internet site: http://www.epa.gov/oppefed1/models/water/.

The drinking water EDWCs recommended for use in the human health dietary risk assessment are those estimated for groundwater.  The highest daily total fenamidone residue concentration in shallow groundwater estimated by PRZM-GW is 207ug/L and the average concentration after breakthrough was 139 ug/L for the Central Sands Region of Wisconsin from 30 years of continuous use.  These estimates represent potential exposure to private drinking water well in a highly vulnerable pesticide use area where numerous pesticide residues have been detected in groundwater.

For both the acute and chronic dietary analysis, HED will use the maximum ground water EDWC of 207 μg/L (0.207 ppm), since it is the highest EDWC reported for fenamidone.

V.  DEEM-FCID Program and Consumption Information

Fenamidone acute and chronic dietary exposure assessments were conducted using the DEEM-FCID, Version 3.16, which incorporates 2003-2008 consumption data from USDA's NHANES/WWEIA.  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.  However, for acute exposure assessment, consumption data 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 a 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 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 an acute exposure assessment, 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 analyses performed at all levels of refinement.  However, for deterministic assessments, any significant differences in user vs. per capita exposure and risk are specifically identified and noted in the risk assessment.

VI.  Toxicological Information

The HED Hazard Identification and Assessment Review Committee (HIARC) met on 18-March-2003 to evaluate the toxicological database for fenamidone (TXR No. 0052379).  At that meeting the lack of a developmental neurotoxicity study was indentified and a 10X database uncertainty factor was applied.  Subsequent to that finding, the registrant has addressed the data gap, and HED has determined that the database UF is no longer required.  Based on toxicological considerations and the residue assumptions used in the dietary analyses, HED concludes that the FQPA Safety Factor can be reduced to 1x when assessing acute and chronic dietary exposures.  Table 3 summarizes the points of departure used for dietary risk assessment.

NOAEL = no observed adverse effect level.  LOAEL = lowest observed adverse effect level.  UF = uncertainty factor.  UFA = extrapolation from animal to human (intraspecies).  UFH = potential variation in sensitivity among members of the human population (interspecies).    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 PAD.  The DEEM-FCID(TM) analyses estimate the dietary exposure of the U.S. population and various population subgroups.  The results reported in Table 4 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.

The estimated exposure (food and water) to the U.S. population from the existing and proposed new uses of fenamidone resulted in an estimated risk equivalent to 3% of the aPAD at the 95[th] percentile.  The most highly exposed subpopulation was children 1  -  2 years with an estimated exposure equivalent to 5% of the aPAD at the 95[th] percentile.

The estimated exposure (food and water) to the U.S. population from the existing and proposed new uses of fenamidone resulted in an estimated risk equivalent to 53% of the cPAD.  The most highly exposed subpopulation was children 1  -  2 years with an estimated exposure equivalent to 89 % of the cPAD.

 The results of the acute and chronic dietary exposure analysis are reported in the summary table below (Table 4).  

Fenamidone is not likely to be a human carcinogen; therefore a cancer dietary risk assessment is not required for this chemical.

N/A is "not applicable".  Populations with highest exposure are shown in bold. 
* PAD = population adjusted dose.
 
 VIII. Characterization of Inputs/Outputs
 
 The acute and chronic dietary assessments are considered to be conservative, using field trial data conducted at maximum application rate and minimum PHI and assuming 100% CT for all commodities, as well as using default drying concentration factors and empirical factors.  The results of the acute and chronic dietary risk assessments are unlikely to underestimate risk.  
 
 IX.  Conclusions
 
 Slightly refined  acute and chronic dietary risk assessments were conducted which used maximum field trial residue values, assumed 100 % CT for all commodities and incorporated DEEM(TM) default processing factors as well as empirical factors were used for processed commodities.  
 
The estimated exposure (food and water) to the U.S. population from the existing and proposed new uses of fenamidone resulted in an estimated risk equivalent to 3.4% of the aPAD at the 95[th] percentile.  The most highly exposed subpopulation was children 1  -  2 years with an estimated exposure equivalent to 5% of the aPAD at the 95[th] percentile.
 
The estimated exposure (food and water) to the U.S. population from the existing and proposed new uses of fenamidone resulted in an estimated risk equivalent to 53% of the cPAD.  The most highly exposed subpopulation was children 1  -  2 years with an estimated exposure equivalent to 89% of the cPAD.
 
 Acute and chronic dietary risks from the existing and newly proposed used of fenamidone are not of concern.
