Sedaxane (129223) Dietary Exposure and Risk Assessment 0423821 

Executive Summary 

Acute, chronic, and cancer aggregate dietary (food and drinking water) exposure and risk 

assessments were conducted using the Dietary Exposure Evaluation Model with the Food 

Commodity Intake Database (DEEM-FCID) Version 3.16. This software incorporates 2003-

2008 food consumption data from the U.S. Department of Agriculture's National Health and 

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

were performed to support a Section 3 registration request for seed treatment uses of sedaxane on 

cotton and sugar beet. This memo was reviewed by two members of the DESAC, per the current 

DESAC SOP. 

Acute Dietary (Food and Drinking Water) Exposure Results and Characterization 

A highly conservative acute dietary assessment was conducted using tolerance-level residues, 

100% crop treated assumptions, and screening-level estimated drinking water concentrations 

(EDWCs). At the 951

h percentile of exposure, the estimated risk is< 2% of the acute population 

adjusted dose (aPAD) for the U.S. population and all population subgroups. 

Chronic and Cancer Dietary (Food and Drinking Water) Exposure Results and Characterization 

Partially refined chronic and cancer dietary assessments were conducted using anticipated 

residue levels, percent crop treated data, and screening-level EDWCs. The estimated risk is 

:S 1% of the chronic population adjusted dose ( cP AD) for the U.S. population and all population 

subgroups. Sedaxane has been classified as "Likely to be Carcinogenic to Humans" (TXR No. 

0055854, J. Kidwell, 18-MA Y-11). A linear low-dose extrapolation model (Q,*) was used to 

estimate cancer risk, with a Q, * = 4.64 x 1 o-3 (mg/kg/dayy1

• The cancer risk estimate to the U.S. 

population is 2.0 X 1 o6. 

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) (e.g., no observed adverse effect level; NOAEL, lowest observed 

adverse effect level; LOAEL) divided by the required uncertainty or safety factors. 

For acute and 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: http://www.epa.gov/fedrgstr!EPAPEST/2000/July/Day-12/6061.pdf; or see SOP 99.6 (20-AUG-1999). 

The most recent dietary risk assessment for sedaxane was conducted by W. Donovan (D412218, 

12-JUN-2013).

II. Residue Information

Tolerances for sedaxane are established under 40 CFR §180.665. The residue of concern in 

plants consists of the cis- and trans-isomers of the parent compound. Residue levels in most 

food commodities were less than the limit of quantitation (LOQ) of 0.005 ppm for both isomers. 

Summing these residues resulted in the recommended tolerance level of 0.01 ppm, and this value 

was used in the acute dietary exposure analysis for all food RACs except potato, where the 

residue was 0.02 ppm. 

For the chronic dietary analysis, it was determined that anticipated residues should be used, as a 

screening approach resulted in cancer risk estimates that exceeded 1 x 10-6. Typically, 

anticipated residues for chronic dietary exposure estimates are determined as the average 

residues from field trials or monitoring data. For sedaxane, the anticipated residues were 

conservatively determined as 1⁄2 × tolerance, which was 1⁄2 × LOQ or 0.005 ppm for all food 

RACs except potato, where the anticipated residue was 0.01 ppm. 

In livestock, the residue of concern for risk assessment is parent plus metabolite CSCD658906

(D406945, E. Holman, 19-DEC-2012). However, all current and proposed uses of sedaxane

have been classified as 180.6 (a) (3), no reasonable expectation of finite residues in livestock 

commodities (D407472, W. Donovan, 12-MAR-2013). For the current petition, the 

recommended sedaxane tolerances are shown in Table 1.

The USDA Pesticide Data Program (PDP) monitored pesticide residues in catfish in 2008, 2009, 

and 2010; however, the samples were not analyzed for sedaxane. As a result, residues in fish 

were not included in the assessment.

III. Percent Crop Treated Information

The acute dietary exposure assessments assumed 100% crop treated for all registered and 

proposed crops.

For chronic and cancer dietary exposure assessment, 100% crop treated was assumed for all 

commodities except for soybeans (51%) and wheat (32%), which incorporated average percent 

crop treated estimates. Average percent crop treated estimates were also used for the proposed 

use on potato (67%).

IV. Drinking Water Data

EDWCs used in the dietary risk assessment were provided by the Environmental Fate and 

Effects Division (EFED): “Drinking Water Assessment for the Proposed New Use of Sedaxane

as a Seed Treatment on Corn, Sorghum, Dried Shelled Pea and Bean (Subgroup 6C; except 

soybean), Rapeseed (Subgroup 20A), and Potato” (D405391 & D407956, R. Bohaty & J. 

Hetrick, 18-MAR-2013). EFED confirmed that EDWCs based on the potato use pattern are 

protective of those based on cotton or sugar beet use patterns (D419976, R. Bohaty, 23-OCT2014). Water residues were incorporated in the DEEM-FCID into the food categories “water, 

direct, all sources” and “water, indirect, all sources.” 

The sedaxane residues of concern in drinking water include both isomers of parent sedaxane plus 

CSCD668094 and CSCD668095 (D406945, E. Holman, 19-DEC-2012). 

There are no monitoring data currently available for sedaxane or its residues of concern in 

drinking water. EDWCs were generated using computer modeling procedures. The screening 

model FIRST (FQPA Index Reservoir Screening Tool) was used to calculate the surface water 

EDWCs. Ground water estimates were provided from the ground water model PRZM-GW using 

the GW-GUI (Graphical User Interface, version 1.0, December 11, 2012). For dietary risk 

assessment purposes, the ground water EDWCs were selected as they were higher than the 

corresponding surface water EDWCs. Additional information concerning the water models is 

available at the EPA internet site:

http://www.epa.gov/pesticides/science/models_pg.htm#aquatic.

Maximum application rates for sedaxane as a high-end estimate of exposure in drinking water 

were modeled based on the proposed labels. Chemical specific and model input values were 

chosen in accordance with current EFED input parameter guidance (USEPA, 2009). No data are

available on the amount of sedaxane that may come off a treated seed once it is planted; 

therefore, in all model runs, 100% of sedaxane applied to the treated seed is assumed to be 

available for runoff and leaching in the form of sedaxane or total toxic sedaxane residues. The 

maximum surface and ground water EDWCs for use in the human-health risk assessment for 

sedaxane are shown in Table 2.

V. DEEM-FCID Program and Consumption Information

Sedaxane 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. This software incorporates 2003-2008 food 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 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 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 sedaxane risk assessment team in consultation with the ToxSAC (Toxicology Science 

Advisory Council) selected doses and endpoints for risk assessment. The toxicological doses 

and endpoints used for dietary risk assessment are summarized in Table 3 (D386415, W. 

Donovan et al., 16-FEB-2012).

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 (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. 

The Agency recommends that the 10X FQPA safety factor for the protection of infants and 

children, be reduced to 1X. The risk assessments conducted for sedaxane were based on the 

most sensitive endpoints in the toxicity database, and the NOAELs selected for risk assessment 

are considered protective of potential developmental, neurotoxic, and immunotoxic effects for 

infants and children. Highly conservative exposure estimates were incorporated into the risk 

assessment for sedaxane. There are no residual uncertainties with regard to pre- and/or postnatal toxicity, neurotoxicity, or exposure; therefore, reduction of the 10X FQPA safety factor to 

1X is appropriate.

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 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 50-99 years. Cancer risk is determined for the general 

U.S. population only.

Acute Dietary (Food and Drinking Water) Exposure Results and Characterization

A highly conservative acute dietary assessment was conducted using tolerance-level residues, 

100% crop treated assumptions, and screening-level EDWCs. At the 95th percentile of exposure, 

the estimated risk is < 1% of the acute population adjusted dose (aPAD) for the U.S. population 

and all population subgroups. Results are shown in Table 4.

Chronic and Cancer Dietary (Food and Drinking Water) Exposure Results and Characterization

Partially refined chronic and cancer dietary assessments were conducted using anticipated 

residue levels, percent crop treated data, and screening-level EDWCs. The estimated risk is <

2% of the chronic population adjusted dose (cPAD) for the U.S. population and all population 

subgroups. The estimated exposure of the general U.S. population to sedaxane is 0.000427

mg/kg/day. Multiplying the Q1* of 4.64 x 10-3(mg/kg/day)

-1

by the exposure value results in a 

cancer risk estimate of 2.0 x 10-6. Results are shown in Table 4.

To assess the contribution of just food to the dietary exposure of sedaxane, acute, chronic, and 

cancer analyses were run without modeled water estimates. The results are reported in Table 5, 

including 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 year population 

subgroups.

Results of Acute Dietary (Food Only) Exposure Analysis

A conservative acute dietary assessment was conducted using tolerance-level residues and 100% 

crop treated assumptions. At the 95th percentile of exposure, the estimated risk from food 

sources is < 1% of the aPAD for the U.S. population and all population subgroups. Results are 

shown in Table 5.

Chronic and Cancer Dietary (Food Only) Exposure Results and Characterization

Partially refined chronic and cancer dietary assessments were conducted using anticipated 

residue levels, and percent crop treated data. The estimated risk is < 1% of the cPAD for the 

U.S. population and all population subgroups. The estimated exposure of the general U.S. 

population to sedaxane is 0.000023 mg/kg/day. Multiplying the Q1* of 4.64 x 10-3(mg/kg/day)

-1

by the exposure value results in a food only cancer risk estimate of 1.1 x 10-7. Results are shown 

in Table 5.

VIII. Characterization of Inputs/Outputs
Sedaxane (129223) Dietary Exposure and Risk Assessment D423821

Page 9 of 18

HED has conducted highly conservative acute dietary risk assessments. These assessments 

could be refined using anticipated residue levels instead of tolerance level residues and/or 

percent crop treated data. However, since acute risks were not of concern, no refinements were 

conducted. A food-only exposure analysis demonstrated that food accounts for 13% of the total 

acute dietary exposure to sedaxane for the general U.S. population ([0.000165 mg/kg/day ÷ 

0.001286 mg/kg/day] * 100). 

For the chronic and cancer dietary risk estimates, partially refined dietary risk assessments were 

conducted. The refinements consisted of anticipated residue levels and average percent crop 

treated information. These refinements were included because unrefined cancer risk estimates 

exceeded 1 × 10-6. A food-only exposure analysis demonstrated that food accounts for 5% of the 

total chronic dietary exposure to sedaxane for the general U.S. population ([0.000023 mg/kg/day 

÷ 0.000427 mg/kg/day] * 100). 

IX. Conclusions

HED conducted acute dietary risk assessments which incorporated tolerance level residues, 

100% crop treated assumptions, default processing factors, and conservative, screening-level 

drinking water concentrations. Chronic and cancer dietary risk assessments made use of 

anticipated residues, percent crop treated information [for wheat, soybean, and potato], default 

processing factors, and screening-level drinking water concentrations. Acute and chronic dietary 

risks to all population subgroups were <2% of the aPAD and cPAD. Additionally, cancer risk to 

the US population was estimated at 2.0 x 10-6. HED is confident that these assessments do not 

underestimate risk to the general U.S. population or any population subgroup.
