Federal Register / Vol. 69, No. 223 / Friday, November 19, 2004 / Notices 67735

animals were dosed with 121 ppm 

pinoxaden. Poultry transfer factors were 

derived from a hen metabolism study, 

where the animals were dosed with 97 

ppm pinoxaden.

The results were favorable in both 

acute and chronic assessment scenarios. 

Acute exposures at the (99.9th 

percentile) were 0.11% of the acute 

reference dose (0.3 mg/kg bw/day) for 

women 13–49 years of age, and less than 

0.05% for all other subpopulations. The 

chronic exposure values were negligible 

(<0.05% of the chronic reference dose of 

0.10 mg/kg bw/day for all 

subpopulations).

ii. Drinking water. The acute 

estimated environmental concentrations 

of pinoxaden (including the major 

degradates) in surface and ground water 

are 1.366 ppb (PRZM/EXAMS) and 

0.003234 ppb (SCI-GROW), respectively. 

The acute Population Adjusted Dose 

(aPAD) for pinoxaden (plus degradates) 

is 0.3 mg/kg bw/day for women 13–49 

years of age and 1.5 mg/kg bw/day for 

all other population subgroups. From 

the acute dietary exposure analysis, the 

highest acute food exposure from the 

uses of pinoxaden was 0.000509 mg/kg/

day at the 99.9th percentile for the 20–

49 years old subpopulation. Using this 

information, acute drinking water levels 

of comparison (DWLOC acute) were 

calculated for pinoxaden and the major 

degradates, ranging from 8,990 to 52,487 

ppb. Based on this analysis, pinoxaden 

(plus degradates) estimated 

environmental concentrations (EECs) do 

not exceed the calculated acute 

DWLOCs. The chronic estimated 

environmental concentration of 

pinoxaden (including the major 

degradates) in surface water is 0.21137 

ppb (annual average value from PRZM/

EXAMS). The chronic PAD for 

pinoxaden (plus degradates) is 0.10 mg/

kg bw/day. From the chronic dietary 

exposure analysis, the highest exposure 

estimate of 0.000047 mg/kg bw/day was 

determined for the children 1–2 years 

old subpopulation. Based on the EPA’s 

‘‘Interim Guidance for Conducting 

Drinking Water Exposure and Risk 

Assessments’’ document (62 FR 63662, 

December, 2, 1997), chronic DWLOC 

chronic were calculated for pinoxaden 

(plus degradates), ranging from 999.5 to 

2999.4 ppb. Based on this analysis, 

pinoxaden (plus degradates) EECs do 

not exceed the calculated chronic 

DWLOCs.

2. Non-dietary exposure. There are no 

sources ofnon-dietary exposure, as 

pinoxaden will be registered for 

agricultural uses only and will not be 

available for any residential or public 

uses.

D. Cumulative Effects

The potential for cumulative effects of 

pinoxaden and other substances that 

have a common mechanism of toxicity 

has also been considered. Pinoxaden, is 

a member of the new phenylpyrazolin 

class of herbicides. There is no reliable 

information to indicate that toxic effects 

produced by pinoxaden would be 

cumulative with those of any other 

chemical including another pesticide. 

Therefore, Syngenta believes it is 

appropriate toconsider only the 

potential risks of pinoxaden in an 

aggregate risk assessment.

E. Safety Determination

1. Infants and children. In assessing 

the potential for additional sensitivity of 

infants and children to residues of 

pinoxaden, data from developmental 

toxicity studies in the rat and rabbit and 

a two-generation reproduction study in 

the rat have been considered. In a multigeneration reproductive study, there 

were no indications of any differences 

in sensitivity to pinoxaden exposure 

between the different generations or 

between animals and offspring. The 

parental NOAEL for both sexes was 

considered to be 250 mg/kg/day. 

Offspring effects were not observed at 

dose levels that did not produce 

parental toxicity. Pinoxaden was not 

teratogenic and not directly toxic to the 

progeny in a developmental toxicity 

study in rats. The NOEL for both 

maternal and developmental toxicity 

was 30 mg/kg/day. Pinoxaden was not 

teratogenic in rabbits, and the maternal 

NOEL was 10 mg/kg/day. The NOEL for 

fetuses was 30 mg/kg/day. Since the 

NOEL for fetal effects was higher than 

the NOEL for maternal effects, there was 

no indication of a greater sensitivity of 

fetuses to pinoxaden administration. 

FFDCA section 408 provides that EPA 

may apply an additional safety factor for 

infants and children in the case of 

threshold effects to account for prenatal 

and postnatal toxicity and the 

completeness of the database. Based on 

the current toxicological requirements, 

the database for pinoxaden relative to 

prenatal and postnatal effects for 

children is complete. Further, the 

developmental studies showed no 

increased sensitivity in fetuses as 

compared to maternal animals following 

in utero exposures in rats and rabbits, 

and no increased sensitivity in pups as 

compared to the adults in the multigeneration reproductive toxicity study. 

Therefore, it is concluded that an 

additional uncertainty factor is not 

warranted to protect the health of 

infants and children and that RfDs of 0.3 

mg/kg/day (acute exposures to women 

13–50 yrs of age), 1.5 mg/kg/day (acute 

exposures to general population) and 

0.10 mg/kg/day (chronic expsoures) are 

appropriate for assessing aggregate risk 

to infants and children of pinoxaden. 

Chronic and acute aggregate exposures 

to all infants (<1 year old) is less than 

0.2% of the acute and chronic RfDs. 

Therefore, based on the completeness 

and reliability of the toxicity database, 

Syngenta concludes that there is 

reasonable certainty that no harm will 

result to infants and children from 

aggregate exposure to pinoxaden 

residues.

F. International Tolerances

There are no tolerances or maximum 

residue limits set for pinoxaden in any 

country at the time of this filing.
