Executive Summary

Chronic aggregate dietary (food and drinking water) exposure and risk
assessments were conducted using the Dietary Exposure Evaluation Model
(DEEM-FCID(, Version 2.03), which uses food consumption data from the
USDA’s Continuing Surveys of Food Intakes by Individuals (CSFII) from
1994-1996 and 1998.  In addition to residues in/on food items, the
assessment also addresses potential residues in drinking water.  In this
analysis the chronic dietary exposure and risk estimates resulting from
food and water intake were determined for the general U.S. population
and various population subgroups.  Flonicamid has no acute endpoint and
has been determined to be “not a carcinogen;” therefore only a
chronic analysis was performed to support a petition for tolerances in
conjunction with an IR-4 petition for a Section 3 registration for the
new uses of flonicamid in/on vegetable, root crop (except sugar beet,
subgroup 1B), radish, tops, tuberous and corm vegetable (subgroup 1C),
Brassica, leafy greens 

(subgroup 5B), turnip (greens), hop, dried cones, and okra.  Tolerances
have already been established under 40 CFR 180.613 on cotton, cucurbit
vegetables, fruiting vegetables, leafy vegetables (group 4 except
Brassica, except spinach), spinach, pome fruit (group 11), potato, stone
fruit (group 12), head and stem Brassica (subgroup 5A) and mustard
greens.

Chronic Dietary Exposure Results and Characterization

A chronic dietary (food and drinking water) exposure assessment was
conducted for the proposed commodities, registered commodities and
drinking water.  Except for water, a conservative unrefined assessment
was conducted.  The residue levels used in the assessment were the
tolerance levels recommended by HED for the new commodities, the
tolerance levels established under 40 CFR.§180.613 for registered crops
(head and stem Brassica, cotton, cucurbit vegetable, fruiting vegetable,
leafy vegetable, mustard greens, potato, pome fruit, spinach and stone
fruit),  and revised tolerance levels for livestock commodities.  

Estimated concentrations of 1.5 ppb (1.5 x 10-3 ppm) for the 1 in 10
year annual mean concentration of flonicamid in drinking water from the
proposed uses were provided by EFED and incorporated directly into the
chronic assessment.  A Tier II drinking water assessment for the
proposed uses was performed using PRZM/EXAMS modeling with index
reservoir (IR) scenarios and percent crop area (PCA) adjustment factors.

The chronic dietary (food and drinking water) exposure to flonicamid is
below HED’s level of concern for the general U.S. population and all
population subgroups.  The chronic dietary exposure estimates are 10%
cPAD for the general U.S. population, 15% cPAD for all infants (<1 year
old), and 23% cPAD for children 1-2 years old, the most highly exposed
population subgroup.

Acute Dietary Exposure Results and Characterization

An acute dietary risk assessment was not performed as flonicamid has no
acute toxicological endpoint.

Cancer Dietary Exposure Results and Characterization

A cancer dietary assessment was not conducted as flonicamid has been
determined to be “not a carcinogen.” 

 

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 point of departure (POD, NOAEL, LOAEL,
e.g.) divided by the required uncertainty or safety factors.

For non-cancer chronic exposures, HED is concerned when estimated
dietary risk exceeds 100% of the PAD.  HED is generally concerned when
estimated cancer risk exceeds one in one million. 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,

SOP 99.6 (20-AUG-1999).

The most recent dietary risk assessment for flonicamid was conducted by
Amelia Acierto 

(26-April-2005, DP Number 315611).

II.	Residue Information    

 

Flonicamid Use:

Flonicamid is a Group 9C insecticide (selective feeding blocker)
registered for the control of a variety of aphid pests and the
suppression of a variety of non-aphid pests.  Tolerances for registered
commodities can be found in 40 CFR.§180.613.  The tolerances that are
currently being recommended are listed in Table 1, below.    The residue
of concern for plants are parent flonicamid and its major metabolites
TFNA-AM, TFNA and TFNG; in ruminants are parent and its metabolites
TFNA-AM and TFNA. 

Residue Data used for Chronic Assessments:

The residue levels used in the chronic assessment were the established
tolerance levels for plant commodities established under 40 CFR
§180.613 and the tolerance levels based on the crop trials for the
proposed crops.  Most of the livestock commodity tolerances are being
increased because all regulated residues are going to be included in the
tolerances.  See Table 1, below for the increased livestock commodity
tolerances. 

Estimated concentrations of flonicamid in drinking water from the
proposed uses were provided by EFED and incorporated directly into the
chronic assessment.  

The assessments used 100% crop treated.

Processing Factors:

Separate tolerances were established for dried potatoes, tomato paste,
and tomato puree based on processing studies.  The adjustment factor #1
was set to 1.0 for these commodities; the DEEM default processing
factors were used for the other processed commodities for which default
processing factors are available. 

III.  Drinking Water

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  Assessment for  the IR-4 New
Uses of Flonicamid on Brassica, Hops, Tubulars, and Okra. Including The
Flonicamid Degradation Products (TFNG, TFNA, TFNA-OH, TFNA-AM and
TFNG-AM).”   Water residues were incorporated in the DEEM-FCID into
the food categories “water, direct, all sources” and “water,
indirect, all sources.” 

No monitoring data of flonicamid were available to the Environmental
Fate and Effects Division (EFED).  The estimated drinking water
concentrations from surface water sources were calculated using the Tier
II PRZM (Pesticide Root Zone Model) and EXAMS (Exposure Analysis
Modeling System).  PRIZM is used to simulate pesticide transport as a
result of runoff and erosion from an agricultural field and EXAMS
estimates environmental fate and transport of pesticides in surface
water.  The values generated by the models for drinking water were
multiplied by a national crop area factor (PCA), which accounts for the
fact that it is unlikely for any basin to be completely planted to
agricultural crops.  Ground water concentrations were estimated using
the Tier I SCI-GROW Model.  Flonicamid may be applied by aerial or
ground as per the labels for this product.   This memo only addresses
the estimations of parent flonicamid and its major metabolites, TFNG,
TFNA, TFNA-OH, TFNA-AM and TFNG-AM.  

Based on modeling results, the estimated drinking water (surface water)
concentrations of combined residues of flonicamid and its degradation
products (based on three aerial applications at the rate of 0.089 lb
ai/acre and the values adjusted with PCA factor of 0.87) are:

  

9.8 µg /L for the 1 in 10 year annual peak concentration (acute) - 
Based on the Florida carrot scenario.  

1.5 µg /L for the 1 in 10 year annual mean concentration (non-cancer
chronic)- Based on the California lettuce and Maine potato scenario.   

0.97µg /L for the 30 year annual mean concentration (cancer chronic) - 
Based on the Idaho potato scenario.   

Both the acute and chronic estimated concentrations for flonicamid in
ground water using the SCIGROW (version 2.3) Model are 1.32 x 10-3 µg/L
(ppb) for the combined residues. 

In general, the linked PRZM/EXAMS  Model produces estimated aquatic
concentrations that are expected to be exceeded once within a 10-year
period.

The model and its description are available at the EPA internet site:

IV.	DEEM-FCID™ Program and Consumption Information

Flonicamid chronic dietary exposure assessment wase 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

Toxicological Endpoints and Doses for Chronic Dietary Risk Assessment

The toxicity database for flonicamid was evaluated by HED's Registration
Action Branch III's Toxicology Team on 9/30/2004.  The Toxicology Team
at that meeting selected endpoints and evaluated for FQPA concerns the
potential hazard and exposure data for flonicamid and determined that
there was no need for an additional safety factor for the protection of
infants and children.  The Cancer Assessment Review Committee met on
1/5/2005.  The findings of those meetings, as related to dietary
exposure, are summarized in Table 2.  Flonicamid is classified to be
category “Suggestive Evidence of Carcinogenicity, but Not Sufficient
to Assess Human Carcinogenic Potential,” according to the EPA Draft
Guidelines for Carcinogen Risk Assessment dated July, 1999; therefore, a
cancer assessment is not necessary.

VI.	Results/Discussion

 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 3 below 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 (Food and Drinking Water) Exposure Analysis		
		

The results of the chronic dietary (food and drinking water) exposure
analysis are reported in Table 3 below.      

The chronic dietary (food and drinking water) exposure to flonicamid is
below HED’s level of concern for the general U.S. population and all
population subgroups.  The chronic dietary exposure estimates are 10%
cPAD for the general U.S. population and 15% cPAD for all infants (<1
year old), and 23% cPAD for children 1-2 years old, the most highly
exposed population subgroup.

VII.	Characterization of Inputs/Outputs

The chronic dietary exposure analysis is a conservative one.  As a
result, HED is confident that exposure is not underestimated to the U.S.
population or any population subgroup.  Further refinements could be
made; however, they are not necessary at the present time.

VIII.	 Conclusions

The chronic dietary exposure assessment was conducted for the proposed
uses on root vegetables (except sugar beet; subgroup 1B), tuberous and
corm vegetables (subgroup 1C), leafy Brassica greens (subgroup 5B),
turnip greens, hops, dried cones, and okra and drinking water.  A
conservative assessment was conducted.  Estimated concentrations of
flonicamid in drinking water from the proposed uses were provided by
EFED and incorporated directly into the chronic assessments.  

The chronic dietary (food and drinking water) exposure to flonicamid is
below HED’s level of concern for the general U.S. population and all
population subgroups.  The chronic dietary exposure estimates are 10%
cPAD for the general U.S. population and 15% cPAD for all infants (<1
year old), and 23% cPAD for children 1-2 years old, the most highly
exposed population subgroup.
