Use Pattern and Formulations

Fenazaquin belongs to the quinazoline class of chemicals and is a pesticide intended to
control mites and insects (especially whiteflies).  Its route of exposure is ingestion and
dermal, and its mode of action is the disruption of the biochemistry of insect
mitochondria.
In 2005 countries throughout Europe, North Africa, the Middle-East, Asia, and in Latin
America had approved its use on pome and citrus fruits. The majority of usage (>80%) is
in Europe. Table 1 provides a general summary of the use directions for apples, pears
and citrus fruits.  The Agency also received a label  for a 200 g/L F1C formulation from
the U.K., with use directions for apples.  This U.K.  label specifies a maximum use rate of
150 g ai/ha on apples with a 30-day PHI.

Irrespective of dose, most of an orally
administered radiolabeled fenazaquin
was in rat excreta (89.5-107.7%) at
168 hours with approximately 20%
of the radiolabel in urine. After
initial uniform distribution, about
0.5-1.6% of the dose was in the
carcass and below 0.04% of the dose
in each tissue. There was no
radiolabel in the expired air and no
evidence for bioaccumulation. Based
on excretion and tissue residue data,
bioavailability is conservatively
estimated at about 20% of an
administered dose.
Non-metabolized fenazaquin was
higher in feces (1.0-15.0% of
administered dose) than in urine
(below 0.5% of dose) and some of
the major metabolites were identified
including AN-1 (urine) in addition to
the fecal metabolites F-l, F-2 and F3.
The metabolic pathway of fenazaquin
involved cleavage of the ether bond,
resulting in the formation of the
respective alcohol (4-OH quinazoline
metabolite) and carboxyl acid (AN-1)
derivatives. Other biotransformation
reactions included oxidation of one of
the methyl groups on the alkyl side
chain to produce either an alcohol (F-
1) or carboxylic acid (F-2)
metabolites. Finally, hydroxylation at
the O-ether alkyl moiety of F-l or the
2-position of the quinazoline ring of
F-2 resulted in F-l A and F-3
metabolites, respectively.

Acceptable/non-guideline
Fenazaquin and several of its analogs
(with varying susceptibilities to
metabolism of the ether bond or the
alkylbenzene substituents) were
assessed for their ability to increase
liver peroxisomal fatty acyl-CoA
oxidase (FAO, a marker of
peroxisomal proliferation) and
relative liver weight in groups of five
CD-I female mice. The FAO
peroxisomal activity data indicate
that oxidation of the t-butyl
substituent on the alkylbenzene
moiety (to the corresponding
carboxylic acid) of fenazaquin and
related compounds appears to be the
critical step for heptatocellular
peroxisome proliferation.
4. Hazard Characterizations
a. Acute Exposure

Fenazaquin is acutely toxic when administered orally in rats (LD50 = 134/138 mg/kg in
males/females). No data were made available on acute toxicity by other routes of
exposure.

b. Repeated Exposure

The major findings following repeated oral administration in rats, hamsters and dogs
were decreases in body weight, body weight gain, food intake, and food efficiency.
With one exception, these findings occurred at the highest tested dose (< 35 mg/kg/day)
in each of the  subchronic or chronic toxicity studies.

In the 90-day hamster study which used doses up to 150 (males) and 100 (females)
mg/kg/day, the magnitude of the decrease was dose-dependent for body weight (8-23%
and 19-28% in males and females, respectively)  and body weight gain (16-74% and 39-
61% in males  and females, respectively); however, due to food spillage problems, food
consumption and efficiency data were not presented. In the same study, testicular
atrophy (dose-dependent decreased weight and hypospermatogenesis) and decreased
prostate weight/relative weight were also evident at 75 and 150 mg/kg/day.

At the doses used (< 35 mg/kg/day) in all remaining subchronic and chronic toxicity
studies, there were no organ specific toxicity findings.

Similar effects on body weight/weight gain and food intake/efficiency were also
identified in parental animals of the rat developmental  and reproduction studies and
in the offspring of the reproduction rat  study. There were no developmental findings
in the rat study (up to 40 mg/kg) and no parental or developmental findings of any kind

-------
up to 60 mg/kg/day in the rabbit developmental study.

There are no specific neurotoxicity studies, including acute-, subchronic-, or
developmental.  There is no clear evidence of consistent neurotoxicity findings in the
available toxicity studies. Findings of excessive salivation in the rat reproduction toxicity
study are unlikely to be a sign of neurotoxicity since the chemical is not known to have a
neurotoxic mode of action and no similar clinical findings were reported in the 90-day or
chronic/carcinogenicity studies.

Fenazaquin appears to increase peroxisomal proliferation in rats and mice but hamsters
were resistant since peroxisomal beta oxidation was not increased in the 90-day hamster
study.

A supplementary report (MRID 44742910) was provided as justification for using the
hamster as an appropriate animal model for fenazaquin. Based on the report,  the NOAEL
in a three-month feeding study in mice was 150 mg/kg/day in males and > 600 mg/kg/day
in females and the only  effect observed was a decrease in body weight gain. (The actual
90-day mouse study was not made available to EPA.) In the similar rat and hamster
toxicity studies, the NOAEL was 10 and 25 mg/kg/day, respectively, based on decreased
body weight gain (in addition to hamster testicular atrophy) thus showing that the rat and
hamster were more sensitive to the effects of fenazaquin than mice.  Additionally, a
comparative pharmacokinetic analysis showed that peak plasma levels were not
proportional to dose in both male and female mice, but area under the curve (AUC) was
well correlated to dose.  Peak plasma levels were observed between 0.5-4 hours post
dosing.  Plasma elimination rate of fenazaquin was dose dependent and became slower at
doses >300 mg/kg.  Conversely, rat peak plasma level was reached  in 8 hours and AUC
was proportional to dose while elimination was independent of dose.  Results from  the
pharmacokinetics study indicated similar pharmacokinetics of radiolabeled fenazaquin in
the hamster at doses between 5 and 125 mg/kg with peak plasma levels being reached in
2 hours.

The hamster was chosen over the mouse for a second carcinogenicity study based on
findings in the hamster of slower elimination kinetics and greater systemic toxicity.
Because of the high tolerance of the mouse in regard to effect on body weight gain, the
laboratory chose to use  Syrian golden hamsters as a secondary rodent model,  along with
rats.

5. Food Quality Protection Act Considerations

Based on the hazard and exposure data, the fenazaquin risk assessment team has
recommended that the FQPA Safety Factor be reduced to IX because:

   a.   there is an adequate toxicity database for the food import tolerance on fenazaquin;
   b.   the exposure data are  complete or are estimated based on data that reasonably
       account for potential exposures;
   c.   there is no evidence of susceptibility following in utero and/or postnatal exposure
       in the developmental toxicity studies in rats or rabbits, and in the two-generation
                                       10

-------
       rat reproduction study;
   d.  there are no residual uncertainties concerning pre- and postnatal toxicity;
   e.  the dietary food exposure assessment utilizes proposed tolerance level or higher
       residues and 100% CT information for all commodities and, therefore, will not be
       underestimated;
   f.  there is no potential for dietary drinking water exposure;  and
   g.  there are no residential uses.

6. Classification of Carcinogenic Potential

EPA reviewed the carcinogenicity study in hamsters, as well as the carcinogenicity study
conducted in rats, the mutagenicity studies, and discussed the possible carcinogenic mode
of action of fenazaquin.  Based on the weight of evidence of these studies, and in
accordance with the 2005 Guidelines for Carcinogen Risk Assessment, the members
concluded that the negative hamster findings along with the negative tumor findings in
the 24-month rat study and negative mutagenicity findings support a cancer classification
of "Not likely to Be Carcinogenic to Humans" for fenazaquin.  EPA concluded that
the carcinogenicity study in hamsters is "Acceptable/Guideline"  and satisfies the
guideline requirement for a carcinogenicity study [OPPTS 870.4200; OECD 451] in
hamsters. Despite the enteritis and administration of antibiotics, the study is considered
acceptable based on the adequacy of dosing based on evidence of systemic toxicity,
acceptable survival rate at  17 months, and lack of evidence for tumorigenicity in two
species, hamsters and rats.

8. Dietary Exposure and Risk

Acute and chronic dietary risk analyses were made with the DEEM-FCID™ model to
form a conservative evaluation of exposure for fenazaquin. The acute dietary analysis
made at the 95th percentile indicate risk estimates are reasonably below the 100% of the
aPAD threshold level of concern for each population subgroup.  For the most highly
exposed population subgroup, children 1-2 years of age, acute dietary risk was estimated
to be 48% of the aPAD with an exposure of 0.047574 mg/kg/day.  In conjunction,
chronic analysis yielded risk estimates well below the 100% of the cPAD threshold level
                                          12

-------
of concern for each population subgroup. Likewise, for children 1-2 years of age,
chronic dietary risk proved to be 25% of the cPAD with an exposure of 0.012690
mg/kg/day. Table 6 summarizes the results of the acute and chronic dietary assessments.

9. Anticipated Residue and Percent Crop Treated (%CT) Information

EPA assumes that fenazaquin residues are in/on all registered food commodities at
tolerance levels and that 100% of all PsACs are treated.

10. Aggregate Risk Assessments and Risk Characterization

There are no proposed or existing residential uses for fenazaquin. The proposed use is
limited to apples,  pears and citrus fruits exported to the U.S. only.  The exposure/risk
assessment is limited to dietary food only (no aggregate).

11. Occupational Exposure and Risk

As this assessment is for an import tolerance, the anticipated exposure route for the US
population is via the diet (food only). Thus, occupational exposure risk assessments for
incidental oral, dermal, and inhalation routes of exposure are not required.
                                        13

12. Proposed and Established Tolerances

Table 7 lists the proposed and established tolerance for Fenazaquin.  EPA established no
tolerances for livestock commodities as EPA does not expect any residues in those
commodities.

unlikely to be imported.
13.  Data Gaps

   A.  Current Import Tolerances

       1.  Additional storage stability data are required on apples to support the sample
          storage intervals from the tests conducted on pears and apples in Argentina
          during 1993/94 and on apples in Chile during 1995.  Gowan must submit data
          demonstrating the stability of fenazaquin in frozen apples for intervals up to
          25 months.

       2.  Gowan must submit a reference standard for fenazaquin to the National
          Pesticide Standards Repository.

   B.  Future Tolerances

       1.  Radio validation data demonstrating the extraction efficiency of the proposed
          single analyte enforcement methods were not submitted. However, the
          available data indicate fenazaquin tolerances may be enforced using the
          existing FDA Multiresidue Methods in PAM, Vol I.  Testing of fenazaquin
          through the multiresidue methods indicated that fenazaquin was adequately
          recovered from whole oranges and from orange oil. Radiovalidation data for
          the single analyte methods should be submitted with future petitions.
                                       14

-------
       2.  For future petitions, the following information is needed for each of the ILV
          studies: (i) a description of the number of trials required to obtain the reported
          recovery values; (ii) a description of any problems encountered and a written
          description of any changes or modifications that were made to the method
          during the ILV; (iii) discussion of any steps considered critical; (iv) time
          required for analysis of one set of samples; and (v) details of communications
          between the independent laboratory and the method developers or others
          familiar with the method.

       3.  Gowan must develop and validate (ILV and radiovalidation) an analytical
          enforcement method capable of quantitating parent fenazaquin and its dimer
          prior to conducting crop field trial studies to support any new uses.

14. Labeling Deficiencies

       Although a general summary of the use directions on apples,  pears and citrus
       fruits was provided, additional information is required detailing the maximum
       allowed use rates and minimum PHIs allowed for apples, pears and citrus fruits in
       each country in which these uses are allowed.  Representative labels (and
       translations) should be submitted for each crop from the major growing regions
       (Europe, South America, and Asia).
