Executive Summary 

Acute and chronic dietary risk assessments was conducted for cyromazine using the Dietary 

Exposure Evaluation Model software with the Food Commodity Intake Database (DEEMFCIDTM), Version 3.16, which incorporates consumption data from USDA's National Health and 

Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA).The analysis was 

performed to support a Registration Review of Cyromazine. 

This memorandum was reviewed by two peer reviewers ofthe DESAC, per DESAC SOP 

2012. 1. 

Acute Dietary Exposure Analysis Results and Characterization 

A conservative acute dietary exposure analysis was performed for the general U.S. population 

and various population subgroups. Tolerance level residues and 100% percent crop treated 

assumptions were used. DEEM default and empirical processing factors were used to modify the 

tolerance values. The acute analysis incorporated the peak groundwater estimate from 

application of cyromazine to succulent beans using the PRZM-GW model. Acute dietary risk 

estimates are not of concern for general population or other population subgroups. The subgroup 

with the highest risk estimate was children 1-2 years old with a aPAD of 18%. The aP AD for the 

general U.S. population was 7.6%. 

Chronic Dietary Exposure Analysis Results and Characterization 

A conservative chronic dietary exposure analysis was performed for the general U.S. population 

and various population subgroups. Tolerance level residues and 100% percent crop treated 

assumptions were used. DEEM default and empirical processing factors were used to modify the 

tolerance values. The chronic analysis incorporated the 10 year average surface drinking water 

estimate from the PRZM-GW model. Chronic dietary risk estimates are not of concern for 

general population or other population subgroups. The subgroup with the highest risk estimate 

was children 1-2 years old with a cPAD of8.3%. The cPAD for the general U.S. population was 

3.8%. 

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 (RID) divided by the FQPA Safety Factor. 

For acute and non-cancer chronic exposures, HED is concerned when estimated dietary risk 

exceeds 100% of the PAD. References that discuss the acute and chronic risk assessments in 

more detail are available on the EPA/pesticides web site: "Available Information on Assessing

(8/20/99).

The most recent dietary assessment was conducted in support of registration review of 

cyromazine (B. Daiss & T. Morton, D398366, 01/30/13).

II. Residue Information

Residues of Concern 

The metabolism of cyromazine has been studied in celery, head lettuce, and tomatoes. The 

residue of concern is the parent compound cyromazine as determined by the HED Metabolism 

Assessment Review Committee (MARC) (D245214, 11/4/97). The metabolism of cyromazine 

in plants is adequately understood and additional plant metabolism data are not required for this 

proposed use on bean, succulent. Data concerning the metabolism of cyromazine in lactating 

goats and laying hens have been previously submitted. The MARC determined that the residue 

of concern in livestock commodities is the parent compound, cyromazine (D245214, J.B. Stokes, 

4/15/98).

Established Tolerances

Tolerances are established (40 CFR §180.414) for residues of cyromazine in or on a variety of 

commodities ranging from 0.05 ppm (livestock commodities) to 10.0 ppm (brassica vegetables). 

Residues Used in the Acute and Chronic Analysis

For the acute and chronic dietary analysis, tolerance level residues and 100 percent crop treated 

assumptions were used for all treated commodities. Default processing factors were used for all 

processed commodities except potato and tomato commodities for which empirical processing 

factors were used. Residues used in the chronic dietary analysis are provided in Table 2. 

Processing factors for potato and tomato commodities are provided in Table 4.

III. Water Data

Drinking water residues were incorporated directly into the acute and chronic dietary analyses 

(“water, direct, all sources” and “water, indirect, all sources”) and were provided by the 

Environmental Fate and Effects Division (EFED; D398026, T. Dowen, 2/10/12). Because 

PRZM-GW was not available as a screening level model at the time of the cyromazine DWA and 

the PRZM-GW model is being used in FQPA drinking water assessments to estimate pesticide 

concentrations in ground water sourced drinking water, PRZM-GW modeling for cyromazine 

was conducted to update the DWA to adhere to current Agency policy. The estimated 

concentrations in drinking water (EDWC) of cyromazine are not expected to exceed 75.5 μg/L 

for a daily peak concentration in ground water (acute) and 60.9 μg/L for the average 

breakthrough concentration in ground water (chronic) (Table 5). Cyromazine is expected to 

breakthrough into ground water between 3 to 7 years. 

PRZM-GW modeling was conducted using PRZM-GW (version 1.0). Application rate, number, 

and interval are representative of the current maximum label rate for beans. The first pesticide 

application date was May 1 for all the PRZM-GW scenarios. The ground water modeling was 

conducted using a different hydrolysis half-life (stable) and aerobic soil metabolism half-life 

(450 days) than used in the DWA (DP 398026, 2/10/12). As per input parameter guidance, the 

upper 90th percent CL of mean aerobic soil metabolism half-life (147.3 days) was used because 

there are three aerobic soil metabolism half-lives for cyromazine. A hydrolysis half-life of 400 

days was estimated from abiotic hydrolysis data.

IV. DEEM-FCIDTM Program and Consumption Information

Cyromazine acute and chronic dietary exposure assessments were conducted using the Dietary 

Exposure Evaluation Model software with the Food Commodity Intake Database DEEMFCIDTM, 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 
Cyromazine (PC Code 121301) Dietary Exposure and Risk Assessment DP #: 414945

Page 6 of 23

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 foodform (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.

V. Toxicological Information

HED evaluated the toxicology data base for cyromazine and selected doses and endpoints for 

chronic dietary and drinking water risk assessments provided in Table 6.

VI. Results

As stated above, for chronic assessments, HED is concerned when dietary risk exceeds 100% of 

the PAD. The DEEM-FCIDTM analyses estimate the dietary exposure of the U.S. population and 

various population subgroups. The results reported in Tables 7 and 8 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.
