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 conducted in support of a human-health risk assessment for the proposed Section 3 uses of metconazole on the pea and bean, dried shelled, except soybean, subgroup 6C and the sunflower subgroup 20B; expansion of the canola tolerance to the rapeseed subgroup 20A; and conversion of the established stone fruit and tree nut crop groups to the stone fruit group 12-12 and the tree nut group 14-12.  This memorandum was reviewed by two peer reviewers of the DESAC, per DESAC SOP 2012.1. 

Acute Dietary (Food and Drinking Water) Exposure Assessment

An unrefined acute dietary (food and drinking water) exposure assessment was conducted.  The residue levels used in the assessment were the established or recommended tolerance levels except for cereal grains and livestock commodities.  Since cereal grains and livestock commodities include metabolites as residues of concern in the risk assessment, maximum residue values for the metabolites from field trials were added to the metconazole tolerance levels.  DEEM default processing factors or empirical processing factors were used, as available.  It was assumed that 100% of the crops were treated.  

The estimated drinking water concentration (EDWC) used in the acute dietary assessment was provided by the Environmental Fate and Effects Division (EFED) and incorporated directly into the acute assessment.  The groundwater EDWC of 51.8 ug/L (ppb) generated by the PRZM-Ground Water (PRZM-GW) model was used in the acute dietary assessment.  The highest application rate, which was the application rate for turf, was modeled using the WI Central Sand Scenario in estimating metconazole EDWCs for groundwater.  

The acute dietary (food and drinking water) exposure to metconazole is below HED's level of concern for females 13-49 years old, the only population subgroup of concern.  For the general U.S. population, including infants and children, an appropriate dose/endpoint attributable to a single dose was not observed in the available oral toxicity studies.  The acute dietary exposure estimate at the 95[th] percentile is 4.6% of the aPAD for females 13-49 years old, the only population subgroup of concern.

Chronic Dietary (Food and Drinking Water) Exposure Assessment

An unrefined chronic dietary (food and drinking water) exposure assessment was conducted.  The residue levels used in the assessment were the established or recommended tolerance levels except for cereal grains and livestock commodities.  Since cereal grains and livestock commodities include metabolites as residues of concern in the risk assessment, maximum residue values for the metabolites from field trials were added to the metconazole tolerance levels.  DEEM default processing factors or empirical processing factors were used, as available.  It was assumed that 100% of the crops were treated.  

The EDWC used in the chronic dietary assessment was provided by EFED and incorporated directly into the chronic assessment.  The surface water EDWC of 43.9 ug/L (ppb) generated by the Surface Water Concentration Calculator (SWCC) model was used in the chronic dietary assessment.  The SWCC model was used to generate EDWCs for the Tier II aquatic exposure assessment based on the cranberry scenario.  The SWCC is a graphical user interface that runs the Pesticide Root Zone Model (PRZM, v 5, November 15, 2006) and the Variable Volume Water Body Model (VVWM, 3/6/2014) (USEPA, 2006b).  The default percent cropped area (PCA) factor of 1.0 was used.

The chronic dietary (food and drinking water) exposure to metconazole is below HED's level of concern for the general U.S. population and all population subgroups.  The chronic dietary exposure estimates are 6.6% of the cPAD for the general U.S. population and 14% of the cPAD for children 1-2 years old, the most highly exposed population subgroup.

Cancer Exposure Results and Characterization

Metconazole was classified as "not likely to be carcinogenic to humans;" therefore, a cancer dietary assessment was not performed. 

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 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," 6/21/2000, web link:  http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf; or see SOP 99.6 (8/20/1999).

The most recent dietary risk assessment for metconazole was conducted by Amelia Acierto (3/28/2011, D387504).
			
II.	Residue Information

Residues of Concern:  The residues of concern for the tolerance expression and risk assessment (DP# 348234, C. Olinger, 2/11/2008) are summarized in Table 1 below.
The triazole metabolites (1,2,4-triazole, triazolylalanine, and triazolylacetic acid) are also residues of concern, but they are addressed in a separate dietary exposure assessment document (DP# 414951, T. Morton, 10/24/13).

1  For all triazole-containing pesticides, 1,2,4-triazole, triazolylalanine (TA), and triazolylacetic acid (TAA) should also be included as residues of concern for risk assessment purposes only for plant and livestock commodities.  Since these metabolites are common to the entire class of triazole-derivative fungicides and because of differential toxicity between the metabolites and the various parent compounds, risks associated with exposure to 1,2,4-T and to TA/TAA are addressed in separate risk assessment documents.
2  M1 = 5-[(4-chlorophenyl)methyl]-2-methoxyl-2-methyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol;  M11 = 5-[(4-chlorophenyl)methoxyl]-2,2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol; M12 = 5-[(4-chlorophenyl)methyl]-2-carboxyl-2-methyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol; M31 = (1S*,3R*,5S*)-3-hydroxy-cis-metconazole; 1,2,4-T = 1H-1,2,4-triazole; TAA = 1H-1,2,4-triazol-1-yl acetic acid; TA = 2-amino-3-(1H-1,2,4-triazol-1-yl)propanoic acid.

Established Tolerances:  Tolerances are established under 40 CFR §180.617 for residues of metconazole, including its metabolites and degradates, on a variety of raw agricultural commodities.  Compliance with the tolerance levels is to be determined by measuring only metconazole as the sum of its cis- and trans-isomers.  Permanent tolerances have been established for a variety of raw agricultural and processed commodities.  Time-limited tolerances, set to expire on 12/31/14, have also been established on sugarcane cane and molasses.

Recommended Tolerances: In PP#4E8244 (as shown in Table 2 below), the Interregional Research Project No. 4 (IR-4), on behalf of the IR-4 Project and the Agricultural Experiment Stations of Montana, South Dakota, North Dakota, and Colorado (dry bean), Montana, South Dakota, Idaho, and North Dakota (dry pea), and Kansas, Montana, South Dakota and North Dakota (sunflower), requested the establishment of permanent tolerances and registration for use on the pea and bean, dried shelled, except soybean, subgroup 6C, and the sunflower subgroup 20B; expansion of the canola tolerance to the rapeseed subgroup 20A; and conversion of the established stone fruit crop group 12 and tree nut crop group 14 to the stone fruit crop group 12-12 and the tree nut crop group 14-12.

Residue Values Used in This Assessment:  The residue levels used in the assessment are the established or recommended tolerance levels except for cereal grains and livestock commodities.  Since cereal grains and livestock commodities include metabolites as residues of concern in the risk assessment, maximum residue values for the metabolites from field trials were added to the metconazole tolerance levels.  Residue values used for cereal grains and livestock commodities are shown in Table 3 below:

.  
Processing Factors:  DEEM default processing factors were used for apricot, dried (6.0x), banana/plantain, dried (3.9x), cherry juice (1.5x), corn, field, syrup (1.5x), cranberry juice (1.1x), peach, dried (7.0x), peanut butter (1.89x), and plum, prune, juice (1.4x).

Empirical processing factors, based on processing studies, were used for the bran of barley, oat, and wheat (2.0x), wheat flour (1x), wheat germ (1x), soybean oil (1x), sugarcane, sugar (1x) (all D348168, N. Dodd, 2/20/08; processing factors for barley, oat and wheat commodities include residues of parent and metabolite M11 from MRID 46902231); potato commodities (potato, chips; potato, dry) (1x) (D380990, A. Acierto, 3/24/11); rapeseed oil/sesame oil (1x) (D419223, N. Dodd, 11/4/14), and sunflower oil (1x) (D419223, N. Dodd, 11/4/14).  (The processing factor of 1x was used for processing factors which were <=1x.)  A separate tolerance was established for sugarcane molasses under a Section 18 (D341748, B. O'Keefe, 8/15/08); therefore, the processing factor was set to 1.  Separate tolerances were established for peanut oil and sugar beet molasses; therefore, the processing factors were set to 1 (D348168, N. Dodd, 2/20/08).  Although concentration was observed in dried prune (2.3x), it was determined that the tolerance for the raw agricultural commodity is adequate to cover the residues in the processed commodity (D348168, N. Dodd, 2/20/08); therefore, the processing factor for dried prune is set to 1.

The USDA Pesticide Data Program (PDP) monitored pesticide residues in catfish in 2008, 2009, and 2010; however, the samples were not analyzed for metconazole.  As a result, residues in fish were not included in the assessment.

III.	Percent Crop Treated
 
100% crop treated (100% CT) was assumed for all commodities.
 
IV.	Drinking Water Data

The drinking water residues used in the dietary risk assessment were provided by the Environmental Fate and Effects Division (EFED) in the following memorandum: "Drinking Water Exposure Assessment for the Section 3 New Use of Metconazole on Pea and Bean (Dried Shelled, Subgroup 6C), and Sunflower (Subgroup 20B)" (D418674, Faruque Khan, Ph.D., 9/30/14) and incorporated directly into this dietary assessment.  Water residues were incorporated in the DEEM-FCID into the food categories "water, direct, all sources" and "water, indirect, all sources."   

Metconazole parent is the only residue of concern considered in the drinking water assessment.  No degradates of metconazole were included based on the recommendation from the Residues of Concern Knowledgebase Subcommittee (ROCKS) of HED (USEPA, 2008, D348234). 

For surface water, the Surface Water Concentration Calculator (SWCC v 1.106) model was used to generate EDWCs for the Tier II aquatic exposure assessment based on cranberry use. The SWCC is a graphical user interface that runs the Pesticide Root Zone Model (PRZM, v 5, November 15, 2006) and the Variable Volume Water Body Model (VVWM, 3/6/2014) (USEPA, 2006b).  The default percent cropped area (PCA) factor of 1.0 was used.
For peak exposure and annual mean exposure, lower EDWCs for surface water were generated using the Tier II Pesticide Root Zone Model and Exposure Analysis Modeling System (PRZM-EXAMS), based on metconazole use on PA turf with a PCA factor of 1.  The use on turf reflected the highest application rate (i.e., five applications at 0.6 lb ai/A/application with a 14-day retreatment interval).  The modeled EDWCs for pea/bean (dried shelled) and sunflower did not exceed the concentrations from PA turf.  
For groundwater, the PRZM-Ground Water (PRZM-GW) model was used to estimate EDWCs.  The highest application rate, which was the application rate for turf, was modeled in estimating metconazole EDWCs for groundwater.  Since application rates for proposed uses are lower than turf, no additional PRZM-GW modeling was conducted. 

The EDWCs used in HED's human health dietary risk assessment are bolded in summary Table 4 below.   The groundwater EDWC of 51.8 ug/L (ppb) was used in the acute dietary assessment. The surface water EDWC of 43.9 ug/L (ppb) was used in the chronic dietary assessment.

V.  DEEM-FCID Program and Consumption Information

Metconazole 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 risk assessment team selected endpoints or confirmed endpoints that were selected previously.  The Cancer Assessment Review Committee (CARC) for metconazole met on November 2, 2005 (memo, Gregory Akerman, Ph.D., TXR# 0054211, 4/14/06).  The Metconazole Endpoint Selection meeting was held on December 21, 2005.  The Toxicity Advisory Clinic (TAC) met on 1/10/06 to discuss the acute hazard endpoint selection and the FQPA selection.   

The critical studies in which HED has high confidence suggest a low (or no) level of concern for pup susceptibility.  Other data in which HED has a lower level of confidence suggests some level of concern for pup susceptibility.   Taken together, there is low concern (and thus low uncertainty) that the young are more susceptible than adults to metconazole exposures.  Thus, the FQPA factor has been removed (i.e., reduced to 1X). 

A summary of toxicological endpoints for use in human health risk assessment is presented below in Table 5:

 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). 

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 analyses estimate the dietary exposure and risk of the U.S. population and various population subgroups.  The 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 50-99 years old.

Results of Acute Dietary (Food and Drinking Water) Exposure and Risk Analysis

The results of the acute dietary (food and drinking water) exposure and risk analysis at the 95[th] percentile of exposure are reported in Table 6, below.  The acute assessment was performed for females 13-49 years old only, since an acute endpoint was not identified for the general U.S. population.  The acute dietary (food and drinking water) exposure is 4.6% of the aPAD for females 13-49.
 
Results of Chronic Dietary (Food and Drinking Water) Exposure and Risk Analysis

The results of the chronic dietary (food and drinking water) exposure and risk analysis are reported in Table 6, below.  The chronic dietary (food and drinking water) exposure to metconazole is below HED's level of concern for the general U.S. population and all population subgroups.  The chronic dietary (food and drinking water) exposure estimates are 6.6% of the cPAD for the general U.S. population and 14% of the cPAD for children 1-2 years old, the most highly exposed population subgroup.

 VIII.  Characterization of Inputs/Outputs
 
Unrefined acute and chronic dietary exposure assessments were conducted.  Except for cereal grains and livestock commodities, the residue levels used in the assessment were the established or recommended tolerance levels.  For cereal grains and livestock commodities, maximum residue values for the metabolites from field trials were added to the metconazole tolerance levels.  It was assumed that 100% of the crops were treated.  Default and empirical processing factors were used, as available.  EDWCs based on modeling were provided by EFED and incorporated directly into the acute and chronic dietary assessments.  Although not needed at this time, HED could refine the exposure and risk estimates with the following information: 1) projected market share/percent crop treated data;  2) anticipated residue data; and 3) monitoring data.

IX.		Conclusions

Acute and chronic dietary (food and drinking water) exposure assessments were conducted for the proposed/established uses.  The acute dietary (food and drinking water) exposure to metconazole is below HED's level of concern for females 13-49 years old, the only population subgroup of concern.  The chronic dietary (food and drinking water) exposure to metconazole is below HED's level of concern for the general U.S. population and all population subgroups.
