Executive Summary

Acute, chronic, and cancer dietary risk assessments were conducted using
the Dietary Exposure Evaluation Model (DEEM-FCID™, 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.  The analyses were performed to support
a request for regional registration of lactofen on fruiting vegetables
and okra.

All of the assessments assumed tolerance level residues of lactofen in
all commodities and that all commodities consumed were treated.  The
dietary exposures for food alone and food and drinking water are well
below the level of concern for all populations for acute and chronic
exposures.  This is a highly conservative assessment and actual exposure
is likely to be lower.

Acifluorfen, a registered herbicide, is an environmental degradate of
lactofen and may be found in drinking water as a result of lactofen
applications.  Therefore, aggregate acute and chronic assessments were
conducted assuming tolerance level residues of acifluorfen and modeled
estimates of acifluorfen in drinking water as a result of application of
lactofen.  All of the exposure estimates were below the level of concern
for all populations.

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 (RfD) divided by the
Food Quality Protection Act (FQPA) Safety Factor.

For acute and 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 (i.e.,
the risk exceeds 1 x 10-6).  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,” 6/21/2000, web link:     
HYPERLINK
"http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf" 
http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf  ; or see
SOP 99.6 (8/20/99).  The most recent dietary risk assessment for
lactofen was conducted by Felecia Fort (10/30/02, DP 269311).

II.	Residue Information

Lactofen is an early season herbicide currently registered for use on
cottonseed, peanuts, snap beans and soybeans.  The tolerances are listed
in 40 CFR 180.432 and were reassessed in 2003.  On April 4, 2000, the
Metabolism Assessment Review Committee (MARC) determined that the
dietary analysis should be based on the parent, lactofen only.  

Residue Data used for Acute, Chronic, and/or Cancer Assessments:

Tolerance levels were used in the acute, chronic, and cancer assessments
for lactofen and are listed in Table 1 below.

Table 1.  Tolerance Levels Used in Lactofen Dietary Assessment

Crop	Tolerance Level, ppm

Existing Tolerances

   Beans, Snap	0.01

   Cotton, Gin Byproducts	0.02

   Cotton, undelinted seed	0.01

   Peanut	0.01

   Soybean, seed	0.01

Proposed Tolerances

   Fruiting Vegetables	0.02                    

   Okra	0.02



An aggregate assessment for acifluorfen was also conducted because
acifluorfen is an environmental degradate of lactofen.  Tolerance values
for acifluorfen (40 CFR § 180.383) were used and may be found in Table
2.

Table 2.  Tolerance Levels Used in Acifluorfen Dietary Assessment

Crop	Tolerance Level, ppm

Peanut	0.1

Rice, grain	0.1

Soybean	0.1

Strawberry	0.05



No concentration, reduction, or processing factors were used in this
assessment, as concentration of residues was not observed in processing
studies.  Although a tomato processing study was not submitted for
lactofen, no residues were detected in exaggerated rate field trials. 
Therefore, residues exceeding the proposed tolerance would not be
expected in tomato processed commodities.  

 Drinking Water Data

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 and aquatic exposure water
assessments for IR4 Tolerance petition for the new use (R17) of lactofen
on the fruiting vegetable group and okra.” (J. Wolf, D319594,
10/13/06) and incorporated directly into this dietary assessment. 
Acifluorfen is an environmental degradate of lactofen that could
potentially be found in drinking water, and is also an environmental
degradate of another registered herbicide, sodium acifluorfen. 
Therefore, EFED estimated drinking water concentrations for both
lactofen and acifluorfen from lactofen applications, and acifluorfen
from sodium acifluorfen applications.  However, only the contribution
from lactofen applications was incorporated into the acifluorfen
aggregate assessment as lactofen and sodium acifluorfen are not likely
to be used in the same area and the estimated concentrations from the
proposed new uses of lactofen were higher than the sodium acifluorfen
estimates.  Water residues were incorporated in the DEEM-FCID into the
food categories “water, direct, all sources” and “water, indirect,
all sources.”   

The Tier 2 surface water estimated drinking water concentrations (EDWCs)
for lactofen and acifluorfen (a degradate of lactofen) were generated
with standard Florida pepper and Florida tomato cropping scenarios using
PRZM3 and EXAMS, and may be found in Table 3.  PRZM simulates pesticide
fate and transport as a result of leaching, direct spray drift, runoff
and erosion from an agricultural field and EXAMS estimates environmental
fate and transport of pesticides in a surface water body for a 30-year
period (1961-1990).  PRZM and EXAMS were linked by the program PE4-PL
(version 01).  The EDWC assessment for surface water uses single or
multiple sites which typically represent a high-end exposure scenario
from pesticide use on a particular cropped or non-cropped site. 
Ground-water concentrations were estimated using the Tier 1 screening
model SCI-GROW and may be found in Table 4.  The model and its
description are available at the EPA internet site:   HYPERLINK
"http://www.epa.gov/oppefed1/models/water/"

.	DEEM-FCID™ Program and Consumption Information

Lactofen and acifluorfen acute, chronic, and cancer dietary exposure
assessments were 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.

For acute exposure assessments, 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 all tiers of analysis.  However, for tiers 1 and 2, any
significant differences in user vs. per capita exposure and risk are
specifically identified and noted in the risk assessment.

V.	Toxicological Information

On February 22, 2000 the Health Effects Division (HED) Hazard
Identification Assessment Review Committee (HIARC) evaluated the
toxicology database for lactofen, re-assessed the existing reference
dose, and selected the doses and toxicological endpoints for dietary and
non-dietary exposure risk assessments (C. Olinger, D269621, 10/12/00). 
A summary of the doses and toxicity endpoints selected for use in the
various human health risk assessments for lactofen is presented in Table
5.

In response to the preliminary risk assessment for the Tolerance
Reassessment Decision, the registrant submitted a proposed mechanism of
toxicity for the carcinogenicity observed in the chronic rodent studies.
 The Mechanism of Toxicity Assessment Review Committee (MTARC)
determined that the carcinogenicity should be assessed using a margin of
exposure approach (Robert F. Fricke, 3/12/2001, DP Barcode:  D267472). 
The Cancer Assessment Review Committee (CARC) concurred with the
MTARC’s conclusion and classified lactofen as likely to be
carcinogenic to humans at high enough doses to cause the biochemical and
histopathological changes in the liver of rodents, but unlikely to be
carcinogenic to humans below doses causing these changes.

that do not cause the biochemical and histopathological changes in the
liver of rodents.  The chronic endpoint is protective of the
carcinogenic effects so a separate cancer assessment is not needed.



The toxicological endpoints for acute and chronic dietary exposures are
discussed in detail in the revised Health Effects chapter to the Sodium
Acifluorfen RED (K. Farwell, 1/15/2002, DP Barcode D279497) and are
found in Table 6.  Like lactofen, the cancer classification for
acifluorfen was changed as a result of the submission of mechanistic
studies and is now assessed using an MOE approach (K. Farwell,
7/13/2003, DP Barcode D291742)

VI.	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(s) 7, 8, and 9 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 Acute Dietary Exposure Analysis

No endpoints were identified for the general population so the only
assessment was conducted for Females ages 13-49.  The results of the
acute dietary exposure analyses for lactofen are reported in Tables 7
for food alone and Table 8 for food and drinking water.  The results of
the acute dietary exposure analyses for acifluorfen are reported in
Table 9 for food (from acifluorfen applications and drinking water (as
an environmental degradate of lactofen).   All exposures are below the
level of concern, with the lactofen assessments at less than 1% of the
aPAD and the acifluorfen assessment at 6% of the aPAD.

Results of Chronic Dietary Exposure Analysis

The results of the chronic dietary exposure analyses for lactofen are
reported in Tables 7 for food alone and Table 8 for food and drinking
water.  The results of the chronic dietary exposure analyses for
acifluorfen are reported in Table 9 for food (from acifluorfen
applications and drinking water (as an environmental degradate of
lactofen).   All exposures are below the level of concern, with the
lactofen assessments at less than 1% of the aPAD.  The most highly
exposed subgroup in the acifluorfen assessment at 37% of the cPAD was
infants, less than one year old.

VII.	Characterization of Inputs/Outputs

The acute, chronic, and cancer dietary exposure assessments can be
considered highly conservative assessments because they assume all food
consumed bears residues at the tolerance level and all water consumed
has lactofen and acifluorfen in it at levels comparable to an
agricultural area.  Actual exposure to lactofen and acifluorfen is
likely to be much lower.

VIII.	Conclusions

Acute, chronic, and cancer dietary exposure assessments were conducted
for lactofen and acifluorfen, an environmental degradate of lactofen,
including existing uses and proposed uses of lactofen on fruiting
vegetables and okra.  All assessments for food alone, and food plus
modeled estimates of drinking water concentrations were below the level
of concern.  The assessments can be considered highly conservative as
they assumed all the subject crops are treated and bear residues at the
tolerance level.  Actual exposure is likely to be much lower.
