### 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 Agricu lt ure'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 sedaxa ne on potato. This memo was reviewed by two members of the DESAC, per the current DESAC SOP.

Acute D i etary (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 sc reenin g -l evel estima t ed drink in g water concentrations (EDWCs). At the 95th percentile of exposure, the estimated risk is < I % 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 cance r dietary assessments were conducted using anticipated

res idue levels, percent crop treated data, and screening-level EDWCs. The estimated risk i s <1% of the chronic population adjusted dose ( cPAD) for the U.S. population and all population subgroups

### 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). Th is dose is referred to as the population adjusted dose (PAD). The PAD is equ i valent to the point of departure (PoD) (e.g., no observed adverse effect level; NOAEL, l owest obse r ved adverse effec t 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/pest ici des web site : "Avai l able Information on Assessing Exposure from Pesticides, A User's Guide," 21-JUN-2000, web l ink: http: // www

The most recent dietary risk assessment for sedaxane was conducted by W. Donovan (D408793, 20 -F EB

- 2013).

### Page 3 of 15 II. Residue Information

T olerance s for sedaxane are established under 40 CFR § 180. 665. The residue of concern in plants , both primary and rotational crops, 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 anticipate d 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 0.0 1 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, t he 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.

### 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%).Sedaxane (129223 ) Dietary Exposure and Risk Assessm ent D412218



### Page 4 of 15 IV. Drinking Water Data

EDWCs used in the dietary risk assessment were provided by the Environmental Fat e and Effects Division (EFED) : “Drinking Water Assessment for the Proposed New Use of Sedaxane as a Seed Treatment on Corn, Sorgh um, Dried Shelled Pea and Bean (Subgroup 6C; except soybean), Rapeseed (Subgroup 20A), and Potato ” (D405391 & D407956

, R. Bohaty & J. Hetrick

, 18

- MAR

- 20 13 )

. Water residues were incorporated in the DEEM

- FCID into the food categories “water, direct, all sou rces” and “water, indirect, all sources.”

The sedaxane residues of concern in drinking water include b oth isomers of parent sedaxane plus CSCD668094 and CSCD668095 ( D406945, E. Holman, 19

- DEC

- 2012 )

.

T here are no monitoring data currently available for sedaxane or its residues of concern in drinking water

. EDWCs were generated using computer modeling procedures . T he screening model FIRST (FQPA I ndex Reservoir Screening Tool ) was used to calculate the surface water EDWCs. G round water estimates we re provided from the ground water model PRZM

. C hemical specific and model input values were chosen in accordance with current EFED input pa rameter guidance (USEPA, 2009). T wo degradates of sedaxane ( CDCD668094 and CDCD668095 ) were included in the water modeling, and are referred to as total toxic sedaxane residues. 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 as sumed to be available for runoff and leaching in the form of sedaxane or total toxic sedaxane residues. The maximum surface and ground w ater EDWCs for use in the human

### Page 5 of 15 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 NHAN ES/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 po pulation 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 co ncluded 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

- 4 9, females 13

- 49, and adults 50

- 99
years o ld.

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. Ex posure 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

a nd 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 dif ferences in user vs. per capita exposure and risk are specifically identified and noted in the risk assessment.

VI. Toxicological Information

The s edaxane risk assessment team in consultation with the ToxSAC (Toxicology Science Advisory Co uncil ) selec ted doses and endpoints for risk assessment. The toxicological doses and endpoints used for dietary risk as sessment are summarized in T able 3 ( D 386415, W. Donovan et al.

UF H = potential variation in sensitivity among members of the human population (interspecies). FQPA SF = FQPA Safety Factor. PAD = population adjusted dose (a = acute, c = chro nic). RfD = reference dose.


### The Agency recommends that the 10X FQPA safety factor for the protection of infants and children, be reduce d to 1X. T he risk assessments conducted for sedaxane were based on the most sensitive endpoints in the toxicity data base, 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 sed axane

. T here are no residual uncertainties with regard to pre

- and/or post

natal toxicity

, neurotoxicity , or exposure; therefore, reduction of the 10X FQPA safety factor to 1X is appropriate.Sedaxane (129223 ) Dietary Exposure and Risk Assessm ent D412218



### Page 7 of 15 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. Popula tion, all infants (<1 year old), children 1

- 2, children 3

- 5, children 6

- 12, youth 13

- 19, females 13

- 49, adults 20

- 49, and adul ts 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 95 th 

### 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 a ssessments were conducted using anticipated residue levels, percent crop treated data, and screening

- level EDWCs. The estimated risk is <1% 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 0.000293 mg/kg/day. Multiplying the Q 1 

### * of 4.64 x 10 - 3 

### (mg/kg/day ) - 1 

### by the exposure value results in a cancer risk estimate of 1.4 x 10 - 6

### Page 8 of 15 VIII. Characterization of Inputs/Outputs

The 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.

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

con ducted. 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 water

- only exposure analysis demonstrate d tha t wat er exposure accounts for 93 % of the total chronic dietary exposure to sedaxane for the general U.S. population ([0.000272 mg/kg/day ÷ 0.000293 mg/kg/day] * 100)

.

IX. Conclusions

The HED conducted acute dietary risk assessments which incorporated toler ance 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 facto rs, and screening

- level drinking water concentrations

. Acute and chronic dietary risks to all population subgroups were <1% of the aPAD and cPAD. Additionally, cancer risk to the US population was estimated at 1 .4 x 10 - 6



### . HED is confident that the se assessment s do not underestimate risk to the general U.S. population or any population subgroup.
