IV. HUMAN HEALTH RISK ASSESSMENT

   A.  Toxicity

       1.  Acute Toxicity: Metconazole has low or minimal acute toxicity via the oral
          (Category III-IV), dermal (Category III), and inhalation routes of exposure (Category
          IV).  It is moderately irritating to the eye (Category III), and minimally irritating to
          the skin (Category IV); it is not a skin sensitizer.

2.  Subchronic Toxicity: A 28-day oral toxicity study in rats showed decreased body
   weight gain and food consumption at 1000 and 3000 ppm, as well as effects on blood
   cells, increased liver enzyme levels, decreased glucose and decreased cholesterol
   levels at 3000 ppm. Increased liver, spleen, and kidney weights were observed at
   1000 and 3000 ppm. Increased fatty vacuolation and hepatocellular hypertrophy at
   1000 and 3000 ppm were also observed, indicating that the liver is the primary target
   organ for metconazole toxicity. 90-day oral toxicity studies in rat and mouse showed
   similar effects, with hisotpathological changes again demonstrating that the liver is
   the primary target organ for metconazole. A 90-day oral toxicity study in dogs
   showed a decrease in food consumption at 600 ppm in females, and at 6000 ppm in
   males, with a corresponding decrease in body weight gain. All dogs at the high (6000
   ppm) dose  had cataracts by the end of the study.  Effects on blood cells were
   observed in males at 600 ppm, and in both sexes  at 6000 ppm. High dose animals also
   showed histopathological changes in the liver, kidney, and spleen.  Subchronic dermal
   exposure in rats (21 days) did not result in effects on body weight gain, food
   consumption, eyes, hematology, or blood chemistry.  Liver weights were increased in
   females at  500 ppm, and in both sexes at 1000 ppm, as well as decreased thymus
   weights in  males at 500 and 1000 ppm, but these were not considered adverse since
   the histopathology of these organs was normal.

3. Chronic Toxicity:  A chronic toxicity study in rats showed increased liver weights
   in males at 12 months and in females at 24 months, as well as an increase in females'
   spleen weights at 24 months at doses of 13.1 mg/kg/day in males and 53.8 mg/kg/day
   in females. Increased hepatocellular lipid vacuolation and centrilobular hypertrophy
   in both males and females at these doses.  A chronic toxicity study in dogs showed a
   decrease in body weight gain during the first 13 weeks in males, increased incidence
   of Kupffer cell pigmentation in females, and increased alkaling phosphatase activity
   in both sexes at 38.5 and 36.8 mg/kg/day in males and females, respectively.

4. Carcinogenicity: There were no treatment-related increases in tumors in rat and
   mouse carcinogenicity studies after exposure to metconazole.

5. Developmental Toxicity/Developmental Neurotoxicity: A pre-natal  development
   study in rats showed reduced maternal food consumption at 30 and 75 mg/kg/day,
   correlating with poor weight gain, but no increase in pre-implantation loss. Post-
   implantation loss was  significantly increased at 75 mg/kg/day, and an increase in fetal
   visceral abnormalities was also seen at this level. An increase in skeletal
   abnormalities, including extra lumbar ribs, cervical ribs and extra pre-sacral
   vertebrae, was observed at 30 and 75 mg/kg/day. A pre-natal development study in
   rabbits showed a reduction in maternal body weight gain at 40 mg/kg/day, again
   corresponding to a decrease in food consumption. An increase in maternal liver
   weight was also seen at that dose, along with decreased red blood cell parameters and
   increased alkaline phosphatase levels. The 40 mg/kg/day dose also showed increased
   fetal resorptions and a slight decrease in fetal body weight.

   There was  no evidence of neurotoxicity observed in the toxicology database.

-------
      6. Reproductive Toxicity: An acceptable new two-generation reproduction study in
         rats (MRID 46808447) using cis/trans metconazole was submitted and reviewed by
         HED.  This study replaces the two-generation reproduction study with cis-only
         metconazole (MRID 44721608) that was used in the human health risk assessment for
         proposed tolerance on imported bananas (Memo Date: 7/06/06). In the new study,
         parental systemic toxicity was evident at 750 ppm, and included decreased body
         weight and decreased weight gain in male and female parental animals, increased
         incidence of fatty hepatocyte change in male parental animals, and increased
         incidence of spleen congestion in FI parental females.  Offspring toxicity was also
         evident at 750 ppm as decreased viability index on lactation day 0 and reduced body
         weight in F2 offspring.  Reproductive toxicity was evident at 750 ppm as prolonged
         duration of gestation and decreased gestation index driven by dystocia (maternal
         deaths during delivery).

         Available evidence (two developmental toxicity studies and one two-generation
         reproductive toxicity study) suggest there is no concern for pre- and/or post-natal
         toxicity resulting from exposure to metconazole, because the pre and postnatal effects
         observed in rats and rabbits occurred only at maternally toxic dose levels.

      7. Metabolism: Metabolism studies  in rats indicated that metconazole is excreted
         primarily in the feces with greater than 90% of the administered dose excreted by
         three days post-dosing. Biliary excretion is the major route of elimination. Plasma
         kinetic studies show a low potential for bioaccumulation following single or multiple
         dosing regimens and the plasma half-life of low- and high-dose rats was slightly
         shorter in males than females. In an experiment in which the triazole ring was labeled,
         a single high (200 mg/kg) dose of metconazole showed approximately 5% of the
         parent compound was excreted as  free triazole.

       8. Mutagenicity: There is no mutagenicity concern for metconazole. When the
          genotoxic potential of metconazole was tested in several in vitro and in vivo
          mutagenicity assays, all tests were negative with the exception of the chromosomal
          aberration assay (in the presence  of S-9 mix (metabolic activation)).  Overall,
          metconazole is considered to be non-genotoxic.

      9. Toxicology Profile:  The toxicological  profile for metconazole is discussed in Table

10. FQPA Hazard Considerations:  The toxicology risk assessment team addressed the
potential enhanced sensitivity to infants and children as required by FQPA, in accordance with
the 2002 OPP lOx Guidance document, and recommended reducing the 10X FQPA Safety
Factor to IX for the dietary and residential risk  assessments. The recommendation is based on
the following:

      There is no evidence of susceptibility following in utero exposure in the rat and rabbit
       developmental toxicity studies and following both in utero and post-natal exposure in the
       two-generation rat reproduction study.

      There is no evidence of increased susceptibility in the offspring based on the result of the
       two-generation reproduction study.

      The residue levels used in the dietary assessment were the established tolerance levels for
       banana,  soybean commodities, and livestock commodities, and assumed 100% crop
       treated (actions completed previously). Therefore, the acute and chronic dietary, food
       only, exposure is considered an upper bound conservative estimate. The contribution
       from drinking water is minimal. The Agency concludes that the acute and chronic
       exposure estimates in this analysis are unlikely to underestimate actual exposure.

      The drinking water component of the dietary assessment utilizes water concentration
       values generated by model and associated modeling parameters which are designed to
       provide  conservative, health protective, high-end estimates of water concentrations which
       will not  likely be exceeded.

      While there is potential for postapplication residential exposure, the best data and
       approaches currently available were used in the metconazole residential assessment.  The
       Agency  used the current conservative approaches for residential assessment. The Agency
       believes that the calculated risks represent conservative estimates of exposure because
       maximum application rates are used to define residue levels upon which the calculations
       are based.  Exposures are unlikely to be under estimated because the assessment was a

   the relevant exposure scenarios for dietary and occupational human health risk assessments is
   provided in  the table below.  The conventional interspecies extrapolation (10X) and
   intraspecies variation (10X) uncertainty factors were applied for all exposure scenarios. As
   stated above, the FQPA SF for increased susceptibility was reduced to IX for all exposures
   scenarios. A summary of the toxicological endpoints are shown below in Table 4:

           B. Dietary Exposure and Risk

              1. Dietary Exposure from Food and Drinking Water: Acute and chronic dietary
                  (food and drinking water) exposure assessments were conducted for the proposed
                  uses on turf and ornamentals, and all registered food uses (imported bananas, and
                  Section 18 on soybeans), and drinking water.  The residue levels used in the
                  assessment were the established tolerance levels for banana, soybean commodities,
                  and livestock commodities, and assumed 100% crop treated. Therefore, the dietary,
                  food only, exposure is considered an upper bound conservative estimate.

                  Estimated concentrations of metconazole in drinking water  from the proposed uses on
                  turf and ornamentals were provided by EFED and incorporated directly into the acute
                  and chronic assessments.

                  A Tier II drinking water assessment for the proposed uses on turf and ornamentals
                  was performed using PRZM/EXAMS modeling with index  reservoir (IR) scenarios
                  and percent cropped area (PCA) adjustment factors. For the acute assessment the 1 in
                  10 year annual peak concentration of metconazole in drinking water was  used, and is
                  not expected to exceed 45.48 ug /L.  For the chronic assessment, the  1 in 10 year
                  annual average concentration of metconazole in drinking water was used, and is not
                  expected to exceed 31.25 ug /L.

              2.  Aggregate Risk Exposures: Based on the proposed uses  on turfgrass, and that fact
                 that common toxicity endpoints exist for the  incidental oral,  and acute and chronic
                 dietary routes of exposure, then acute, chronic, and short-term aggregate exposure and
                 risk assessments are required.

              3.  Acute Aggregate Risk:  Acute aggregate exposures include food plus drinking water
                 exposures.  The acute dietary exposure estimate at the 95th percentile is 2% aPAD for
                                                                                                   18

-------
   females 13-49 years old, the only population subgroup of concern, which is below the
   Agency's level of concern.

4.  Chronic Aggregate Risk:  Chronic aggregate exposures include food plus drinking
   water exposures.  The chronic dietary (food and drinking water) exposure to
   metconazole is below the Agency's level of concern for the general U.S. population
   and all population subgroups. The chronic dietary exposure estimates are 4% cPAD
   for the general U.S. population and 10% cPAD for all infants (<1 year old), the most
   highly exposed population subgroup.

5.  Short- and Intermediate Term Aggregate Risk: Dietary, incidental oral and
   inhalation routes of exposure have the same toxicity endpoints, and therefore, can be
   aggregated. The short- and intermediate-term aggregate risk assessments take into
   account average (chronic) exposure estimates from dietary consumption of
   metconazole (food and drinking water) and non-occupational/residential use on turf
   (dermal for adults, and dermal plus incidental oral for children). Postapplication
   exposures from the use on turf are considered predominantly short-term (1-30 days).
   Although exposures are expected via the dermal route, quantification of dermal risk is
   not required, since a dermal endpoint was not identified for short-, or intermediate-
   term exposures. Therefore, short- and intermediate-term postapplication aggregate
   risk assessments were conducted only for  average dietary and incidental oral
   exposures to toddlers.

   The short-and intermediate-term aggregate MOEs from dietary exposure (food +
   drinking water) and non-occupational/residential handler exposure (inhalation) for
   adults are 3,000 and 2,900, respectively; which are not of concern, since they are
   greater than the level of concern MOE of  100. The short-and intermediate-term
   aggregate MOEs from dietary exposure (food + drinking water) and non-
   occupational/residential exposure  (incidental oral) for children 1-2 years old are 470
   and 520, respectively; which are not of concern, since it is greater than the level of
   concern MOE of 100.

   These aggregate exposure assessments are considered conservative estimates, that
   should not underestimate risks, because of the following inputs: 1) dietary inputs used
   crop specific (turf) screening level drinking water modeling data (i.e., Tier II surface
   water model); 2) maximum application rates and minimum application intervals were
   used; and 3) conservative SOPs and upper level estimates of exposure were employed.

   6. Cancer Aggregate Risk:  There were no treatment-related tumors observed in
   carcinogenicity studies in rats and mice. As a result, a cancer assessment was not
   conducted.

   7. Cumulative Risk:  Section 408(b)(2)(D)(v) of the FFDCA requires that, when
   considering whether to establish, modify,  or revoke a tolerance, the Agency consider
   "available information concerning the cumulative effects" of a particular pesticide's
   residues  and "other substances that have a common mechanism of toxicity."  Unlike
                                                                                19

-------
      other pesticides for which EPA has followed a cumulative risk approach based on a
      common mechanism of toxicity, EPA has not made a common mechanism of toxicity
      finding as to metconazole and any other substances.  For the purposes of this action,
      therefore, EPA has not assumed that metconazole has a common mechanism of
      toxicity with other substances.  For information regarding EPA's efforts to determine
      which chemicals have a common mechanism of toxicity and to evaluate the
      cumulative effects of such chemicals, see the policy statements released by EPA's
      Office of Pesticide Programs concerning common mechanism determinations and
      procedures for cumulating effects from substances found to have a common
      mechanism on EPA's website at http://www.epa.gov/pesticides/cumulative/.
B. Handler and Worker Risk Assessments

   1. Occupational:  Short- (1 - 30 days) and intermediate-term (1-6 months) exposures
   are possible for occupational metconazole handlers. Only inhalation toxicity endpoints
   were identified for these anticipated exposure durations. A Margin of Exposure (MOE)
   > 100 is adequate to protect occupational pesticide handlers.  All metconazole
   occupational handler MOEs are estimated to be > 100 for the proposed uses, and
   therefore, do not cause concern for FED.

   There is the possibility for agricultural workers to have postapplication exposure to
   metconazole following its use on commercially grown ornamentals in nurseries and
   greenhouses, as well as golf course turf. However, because dermal toxicity endpoints for
   the appropriate durations of exposure were not identified, and because inhalation
   exposure is considered to be insignificant for postapplication exposures, no occupational
   postapplication exposure assessment was conducted.

   2. Residential:  There is potential adult short-term dermal and inhalation exposure to
   metconazole from its proposed use on turf and ornamentals. However, because dermal
   toxicity endpoints for the appropriate duration of exposure were not identified, only
   residential handler inhalation exposures/risks have been assessed.

   An MOE > 100 is adequate to protect residential pesticide handlers. All metconazole
   residential handler MOEs are estimated to be > 100 for the proposed uses, and therefore,
   do not cause concern.

   Adults, adolescents and toddlers may be exposed to metconazole from its proposed
   residential uses.  Adults and adolescents may experience short- and intermediate-term
   dermal exposure from golfing and other activities on treated turf, as well  as from tending
   treated ornamentals. Toddlers may experience short- and intermediate-term dermal and
   incidental oral exposure from activities on treated turf.  Because dermal toxicity
   endpoints for the appropriate durations of exposure were not identified, and because
   inhalation exposure is considered to be insignificant for postapplication exposures, only
   toddler incidental oral postapplication exposures have been assessed.  Chemical-specific
   turf transferable residue studies were submitted for use in estimating postapplication
                                                                                  20

-------
       exposures.

       Postapplication risks to toddlers following the application of metconazole to home lawns
       were calculated for short- and intermediate-term exposures. All MOEs for the toddler
       lawn exposure scenarios were >100, and therefore, are not of concern. In addition the
       total MOE for combined toddler exposures (i.e., hand-to-mouth, object-to-mouth, and
       incidental ingestion of soil) is >100, and therefore, is not of concern.
III. ENVIRONMENTAL RISK ASSESSMENT

   A.  Environmental Fate Characterization:  Metconazole is stable to hydrolysis under
       environmental conditions. It is moderately to slightly degradable by direct photolysis in
       water. However, photodegradation in water is not expected to be a major route of
       dissipation in aquatic systems as metconazole has been shown to partition rapidly to the
       sediment (DT50 in water ranged from 1-15 days) and slowly degrade while in sediment
       (DT50 for total system ranged from 116-814 days). Aerobic soil metabolism is the only
       significant route of degradation of metconazole. Based on three aerobic soil metabolism
       studies, the half-life values are in the range of 192.5 days to 660 days. In a soil photolysis
       study, metconazole degraded with an estimated half-life of 72 days.  Field dissipation
       studies indicate that metconazole dissipated with a DT50 ranging from 33 to 138 days.
       Adsorption/desorption studies of metconazole in four soils (pH 5.8-7.6, 0.74-2.29 % OC)
       produced Koc values ranging between 1026 and 2723 ml/g. This Koc range suggests the
       chemical is slightly mobile (FAO Classes). The ranges of BCFs for edible tissue,
       nonedible tissue, and whole  fish indicate a low potential for bioconcentration in fish.
       Also, given the relative short depuration time, it is considered that the risk for
       bioaccumulation of metconazole in fish is low.

   B.  Exposure Characterization: Metconazole has potential to reach surface water via run-
       off and spray drift and to reach ground water via leaching. However, the submitted
       terrestrial field dissipation studies show no significant leaching of metconazole, and
       ground water modeling estimate a concentration of less than  1 ppb.
       Estimated  environmental concentrations (EECs) in surface water were calculated for
       metconazole  using the Tier  II PRZM/EXAMS  models  and   employing  maximum
       application rates for metconazole usage on turf, small grains,  soybeans,  sugar beets,
       peanuts, stone fruits, and tree nuts.  The peak (l-in-10 year) surface  water EECs were
       between 2.89 and 88.19 |ig/L (dependent on scenario and application method). For the
       terrestrial assessment, EECs for metconazole were calculated using the terrestrial Tier I
       model T-REX using the maximum application rate for the evaluated uses. Upper bound
       dietary EECs ranged from approximately 1.53  ppm  for metconazole residues on fruits,
       pods, seeds,  and large insects for soybean application to 446 ppm on short grass for turf
       application.
   C.  Effects Characterization:    Results  of acute  toxicity  studies  in freshwater  and
       estuarine/marine fish indicate that metconazole is moderately toxic on an acute basis.
                                                                                     21

-------
The LC50 = 1.71 mg ai/L for freshwater fish (28-day study, OECD204) and the LC50 =
6.3 mg ai/L for estuarine/marine fish.  The NOAEC for freshwater fish was 0.00291 mg
ai/L based on dry and wet weights and length. For the eastern oyster, the ECso = 2.0 mg
ai/L based on shell growth. Acceptable or supplemental toxicity data for estuarine/marine
fish (chronic) and for invertebrates (freshwater and estuarine/marine, acute and chronic)
were not provided to the Agency.  In lieu of these data, toxicity data from other conazole
pesticides were use to characterize the  risks,  assuming that  metconazole toxicity was
similar to the other conazoles.
Metconazole is classified as  slightly toxic  to birds based on gavage (LDso  = 777 mg
ai/kg-bwt)  and  dietary (LC50 1078  mg  ai/kg-diet) studies in bobwhite  quail. Adverse
effects were observed in a reproduction study using bobwhite quail (reduction in live 3-
week embryos,  hatching success,  chick survival, chick body weights, and adult female
body weight gain), resulting in a NOAEC of 58 mg ai/kg-diet. the acute toxicity tests for
mammals produced definitive LD50s (combined for males and females) of 566, 660, and
1459  mg ai/kg-bwt  as well  as one non-definitive LDso of  >5000 mg  ai/kg-bwt (no
mortalities). The parental, offspring, and reproductive NOAEC for the 2-generation  rat
study  was  150  mg ai/kg-diet.  Significant  effects  were  categorized as parental,
reproductive, and  offspring.   Parental  effects  include decreased body weight and
decreased weight gain in male and female parental animals, increased incidence of fatty
hepatocyte change in male parental animals, and increased incidence of spleen  congestion
in Fl parental  females. Reproductive effects  included  increased gestation length and
decreased gestation  index  driven by dystocia.  Offspring  effects included  decreased
viability  on lactation day 0  and decreased body weight in F2 offspring.  Results of
available toxicity studies indicate that metconazole is practically non-toxic to honey bees
on an acute contact basis.
Seedling emergence studies and vegetative vigor studies were conducted for ten species
using two different end-use products (Caramba and Metconazole 50 WDG). The studies
with Caramba did not provide any definitive EC25S (all were > 0.097 Ibs ai/acre, the
highest concentration tested). For the seedling emergence study conducted with
Metconazole 50 WDG, the most sensitive monocot was ryegrass (EC25 = 0.78 Ibs ai/acre
and NOAEC = 0.30 Ibs ai/acre), and  the most sensitive dicot was the radish (EC25 = 0.15
Ibs ai/acre and NOAEC = 0.075 Ibs ai/acre). For the vegetative vigor study conducted
with Metconazole 50 WDG, there were no reductions in growth parameters based on the
EC25 (> 0.60 Ibs ai/acre) and NOAEC (0.60 Ibs ai/acre) in the four tested monocots, and
the most  sensitive dicot was radish (EC25 = 0.44 Ibs ai/acre, NOAEC < 0.038 Ibs ai/acre,
and EC05 = 0.0036 Ibs ai/acre).

Contact toxicity studies on the effects of metconazole to honey bees indicate that there
are no effects at concentrations less than 95.3 jig ai/bee.

The most sensitive ECso values for  aquatic vascular plants  and non-vascular plants are
0.022 and 0.081 mg ai/L, respectively. The respective NOAECs are 0.00051 and 0.031
mg ai/L.
                                                                               22

D. Potential Risks to Non-Target Organisms:

   1. Aquatic:  Based on this analysis, direct toxic exposure is expected for
       estuarine/marine fish (chronic), and freshwater and estuarine/marine invertebrates
       (acute and chronic). Available toxicity data for aquatic plants coupled with the results
       of this screening-level assessment show that use of metconazole is likely to result in
       direct toxic exposure to vascular aquatic plants (proposed application to turf and
       ornamentals only) and to non-vascular aquatic plants (proposed application to
       ornamentals only). Labeling restrictions limiting number of applications and requiring
       a buffer zone will reduce these risks.  The specific labeling language addressing these
       concerns is provided below.

   2.  Terrestrial: Results of this screening-level assessment using available toxicity data
       suggest that use of metconazole is likely to result in toxic  exposure  to birds and
       mammals on  an acute basis and  to mammals on  a chronic basis.  ). Labeling
       restrictions limiting number of applications will reduce these  risks.   The specific
       labeling language addressing these concerns is provided below.  The Tier I terrestrial
       plant model, TERRPLANT, was used to assess  risks to terrestrial and semi-aquatic
       plants.  Results of this screening-level assessment suggest that use of metconazole is
       likely to result in toxic  exposure  to semi-aquatic  dicots.  ). Labeling  restrictions
       limiting number of applications  and requiring a buffer zone  will help  reduce these
       risks.  The specific labeling language addressing these concerns is provided below.
       The results of this risk assessment suggest that the patterns of  metconazole use are
       such that they  coincide  in  time  and space to  areas  frequented  by  avian and
       mammalian wildlife.  These areas  have  been of demonstrated use by  wildlife as
       sources of food and cover. The potentially problematic wildlife food items suggested
       by this risk assessment are likely to be present in and around the treated areas. In
       addition,  there is potential for indirect effects to all taxonomic groups due to changes
       in habitat caused by vegetation changes.
       A considerable uncertainty in this assessment comes from the fact that metconazole
       (94% purity used in formulation) comprises two geometric isomers; cis andirons,
       with a typical ratio of 85:15 cis:trans.  The technical grade material is 94 % pure with
       a minimum of 80 % cis isomer.  The submitted data do not provide information on
       the differences in degradation rates between the two geometric isomers or the relative
       contribution of each isomer to the total amount of residues identified in each of the
       environmental fate studies. Therefore, the environmental concentrations presented in
       this risk assessment assume fate properties and degradation rates  are the same for
       both isomers.

       Estimated levels of metconazole in the environment, when compared with minimum
       toxicity values, are likely to result in direct risks to Federally Listed Threatened and
       Endangered ("listed") and non-listed species from several different taxa.  Indirect
       risks are also identified for listed and non-listed species. Labeling restrictions
       limiting number of applications and requiring will reduce these risks. The  specific
       labeling language addressing these concerns is provided below.
                                                                                   23

IV. PROPOSED REGULATORY DECISION

   A.  Unconditional Registration: We recommended registration of metconazole for control
       of diseases in turfgrass and ornamentals.

       1.  Conditional Data:
          850.1075/72-la,c: Freshwater fish LCso,  both cold and warm water fish
          850.1010/72-2a:  Freshwater invertebrate LC50
          850.1055/72-3c:  Estuarine/marine invertebrate LCso
          850.1300/72-4a:  Fish early life stage (estuarine/marine)
          850.1400/72-4b:  Aquatic invertebrate Life cycle Freshwater and Estuarine/marine
          850.1735: Whole Sediment Acute Toxicity invertebrates, freshwater
   B.  Tolerances:  No tolerances are required for the proposed non-food uses of metconazole
       on turf and ornamentals.

   C.  Required Label Statements: End use products containing metconazole as an active
       ingredient will be required to add the following protective language on the product
       labeling:

       1. Environmental Hazards: "Do not apply directly to water, or to areas where surface
          water is present, or to intertidal areas below the mean high water mark. Do not
          contaminate water when disposing of equipment washwater or rinsate. Drift and
          runoff may be hazardous to aquatic organisms in water adjacent to treated areas. "

       2. Directions for Use:

          - "Do not make more than three applications per year (2 Ibs active ingredient/year)."
                                                                                     24
