Executive Summary

D™, Version 2.03) which uses food consumption data from the U.S.
Department of Agriculture’s Continuing Surveys of Food Intakes by
Individuals (CSFII) from 1994-1996 and 1998.  

No toxic effects attributable to a single (i.e., acute) exposure to
spiromesifen have been identified; therefore, an acute reference dose
(aRfD) has not been established for spiromesifen and an acute dietary
exposure assessment has not been conducted.  Also, since there is no
evidence that spiromesifen is carcinogenic to humans; therefore, a
dietary cancer assessment is not required. 

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

A chronic dietary assessment was performed assuming tolerance-level
residues for all commodities with existing and proposed tolerances
except for the leafy-green and leafy-Brassica vegetable subgroups (4A
and 5B) (see residue chemistry discussion, Section II below).  Based on
the dietary exposure levels and the residue data from an available
ruminant feeding study, data indicate that tolerances are now
recommended in milk, whole; milk, fat; in the meat of cattle, goats,
horses, and sheep; in meat, byproducts, of cattle, goats, horses, and
sheep; and in the fat of cattle, goats, horses, and sheep.  For all
commodities, 100 percent crop treated (%CT) as well as DEEM™ Version
7.81 default processing factors were used.  The highest drinking water
estimate of 28 ppb, previously provided by the Environmental Fate and
Effects Division (EFED), was directly incorporated into the chronic
assessment.  The chronic dietary risk assessment shows that for all
included commodities, the chronic dietary risk estimates are below
ARIA’s level of concern (i.e. <100% chronic population adjusted doses
(cPAD).  For the U.S. population the exposure for food and water
utilized 32% of the cPAD.  The chronic dietary risk estimate for the
highest reported exposed population subgroup, children 3-5 years old, is
43% of the cPAD.

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 ARIA 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 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”, 21/06/2000, 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 spiromesifen was conducted
by G. Kramer (DP#s: 329711 and 329859, 8/4/2006) for its use on
greenhouse-grown tomatoes and oats.

II.	Residue Information

Spiromesifen Use:

In this analysis the chronic dietary exposure and risk estimate
resulting from food intake were determined for the general U.S.
population and various population subgroups resulting from the addition
of beans to the existing food uses for spiromesifen.

Residues of Concern in Plants:  Spiromesifen and BSN 2060-enol are the
predominant residues in crops.  The toxicity of BSN 2060-enol is
expected to be comparable to the parent compound.  BSN
2060-4-hydroxymethyl (free and conjugated) is a residue of concern in
leafy vegetables and rotational crops.

Residues of Concern in Livestock:  Spiromesifen and BSN 2060-enol are
the predominant residues in ruminants Additionally, BSN
2060-4-hydroxymethyl (free and conjugated) is a residue of concern in
ruminant commodities.

Tolerances:  Tolerances have been established under 40 CFR
§180.607(a)(1) for the combined residues of spiromesifen and its enol
metabolite, calculated as the parent compound equivalents, in/on primary
crop commodities including field corn, cotton, strawberry, and various
vegetable commodities.  The established tolerances for primary crop
commodities range from 0.02 ppm (field corn grain and tuberous and corm
vegetables, subgroup 1C) to 15 ppm (cotton gin byproducts).

Tolerances have been established under 40 CFR §180.607(a)(2) for the
combined residues of spiromesifen and its metabolites containing the
enol and 4-hydroxymethyl
(4-hydroxy-3-[4-(hydroxymethyl)-2,6-dimethylphenyl]-1-oxaspiro[4.4]non-3
-en-2-one) moieties, expressed as parent equivalents, at 0.05 ppm for
the fat and meat byproducts of cattle, goat, horse, and sheep, and at
0.10 ppm for milk fat.

Under 40 CFR §180.607(d), tolerances for the inadvertent or indirect
combined residues of spiromesifen, its enol metabolite, and its
metabolites containing the 4-hydroxymethyl moiety, calculated as the
parent compound equivalents, have been established for rotational crops
alfalfa, barley, sugar beet, oat, and wheat commodities at 0.03-3.0 ppm.

Residue Data Used for Chronic Assessment:  The chronic assessment was
based on the assumption of tolerance-level residues for all commodities
with existing and proposed tolerances except for the leafy-green and
leafy-Brassica vegetable subgroups (4A and 5B).  An additional
metabolite, BSN 2060-4-hydroxymethyl, was observed in the metabolism
studies of lettuce only, comprising 21% of the total radioactive
residues.  Since this metabolite’s toxicity is expected to be
comparable to the parent compound, it was included in the risk
assessment for leafy crops (subgroups 4A and 5B), but not in the
tolerance expression.  To account for this additional toxicity exposure,
the recommended tolerance level was multiplied by a correction factor of
1.3x, where 1.3 = (Metabolite in Risk Assessment)/(Metabolite in
Tolerance Expression).

Recommended tolerances for bean, edible podded and cowpea forage were
calculated using the maximum residue limit (MRL)/maximum likelihood
estimation (MLE) tolerance spreadsheets.  The calculated tolerances for
bean, edible podded and cowpea, forage are 0.80 ppm and 30 ppm,
respectively.  For the purpose of this petition, ARIA recommends a
temporary tolerance of 86 ppm for cowpea hay which was calculated from
the recommended tolerance for cowpea forage (30 ppm) multiplied by the
conversion factor (2.9x) derived when percentages of dry matter (86% for
cowpea hay and 30% for cowpea forage) are taken into consideration.  No
residue data were submitted for cowpea hay.

DEEM™ 7.81 default processing factors were assumed.  The recommended
tolerances for the current petition were provided by ARIA (DP#: 345985,
D. Rate, 12/5/2007).

As part of the current petition, ARIA recommends establishing the
permanent tolerances listed in Table 1, below.

multiplied by the conversion factor (2.9x) derived when percentages of
dry matter (86% for cowpea hay and 30% for cowpea forage) are taken into
consideration.

III.	Drinking Water Data

The drinking water residues used in the dietary risk assessment were
provided by EFED (DP#: 300469, K. Martin, et. al., 2/17/2005) 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.” 

Because monitoring data are unavailable, estimates for spiromesifen
concentrations were made only with mathematical models.  The models
Pesticide Root Zone Model (PRZM) (version 3.12 beta) and Exposure
Analysis Modeling System (EXAMS) (version 2.98.04) were used to conduct
surface water exposure assessments.  Screening Concentration in Ground
Water (SCIGROW) (version 2.3) was used for groundwater.  Estimated
drinking water concentrations (EDWCs) were generated for the total toxic
residue which includes spiromesifen, the -enol and -carboxy metabolites,
and unextracted material.  The highest estimated surface water
concentrations occurred with the NC sweet potato scenario.  For chronic
assessments the EDWC is 11 ppb.  The groundwater estimate from SCIGROW
is 28 ppb; this was the value used in this assessment.

.	DEEM-FCID™ Program and Consumption Information

A spiromesifen chronic dietary exposure assessment was conducted using
the Dietary Exposure Evaluation Model software with the Food Commodity
Intake Database (DEEM-FCID™, Version 2.03), which incorporates
consumption data from USDA’s Continuing Surveys of Food Intakes by
Individuals (CSFII), 1994-1996 and 1998.  The 1994-96, 98 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 1994-96, 98
CSFII 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+
years old.

For 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.

V.	Toxicological Information

Spiromesifen shows no significant developmental or reproductive effects,
is not likely to be carcinogenic based on bioassays in rat and mouse,
and lacks in vivo and in vitro mutagenic effects.  Based on the
chemical’s mode of action and the available data from multiple
studies, the chemical is not considered a neurotoxin.  There are no
residual uncertainties that indicate the need for a safety factor.  The
FQPA safety factor has been reduced to 1X.

Acute dietary exposure limits for all populations, including infants and
children, were not established since an endpoint of concern attributable
to a single dose was not identified.  In addition, there are no
developmental concerns based on rat and/or rabbit developmental toxicity
studies.  

The chronic RfD (and cPAD) for spiromesifen is 0.022 mg/kg/day based on
the NOAEL (2.2 mg/kg/day).  The uncertainty factor used in determining
cRfD was 100:  10X for interspecies extrapolation; and 10X for
intraspecies variations.

VI.	Results/Discussion 

is concerned when dietary risk exceeds 100% of the cPAD.  The
DEEM-FCID™ analyses estimate the dietary exposure of the U.S.
population and various population subgroups.  The results reported in
Table 3 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.  

Results of Chronic Dietary Exposure Analysis

Spiromesifen chronic dietary (food + water) exposure estimates using the
DEEM-FCID™ software are below ARIA’s level of concern for the U.S.
population and each of the population subgroups, Table 3.  Chronic
dietary exposure utilized 32% of the cPAD for the U.S. population.  The
chronic dietary exposure for the highest reported exposed population
subgroup, children 3-5 years old, was 43% of the cPAD.

The results of the chronic dietary exposure analysis are reported in the
Summary Table (Table 3, below).

The chronic dietary exposure and risk estimates are conservative as they
assumed 100% CT and ARIA recommended/established tolerance-level
residues for all commodities except leafy vegetables.  A 1.3x correction
factor was applied to leafy vegetables to account for the additional
metabolite.  Conservative DEEM-FCIDTM default processing factors were
applied to all processed commodities in the analyses.  The chronic
analysis could be further refined through the use of average residues
based on field trial data, percent crop treated data and/or
preparation/cooking factors.  Since risk estimates are below ARIA’s
level of concern, a more highly refined analysis is not needed at this
time.

VII.	Conclusions

The chronic dietary (food + drinking water) exposure to spiromesifen is
below ARIA’s level of concern for the general U.S. population and all
population subgroups.  The chronic dietary exposure utilized 32% of the
cPAD for the general U.S. population and 43% of the cPAD for children
3-5 years old, the most highly exposed population subgroup.
