BODY WEIGHT AND WEIGHT GAIN (PARENTAL ANIMALS): Body weights in male rats were decreased in a dose-dependent manner. Terminal body weights were approximately 545 grams, 520 grams, 475 grams, and 315 grams in the control, 750, 1500, and 3000 mg/kg/day, respectively (results were approximated from a figure). In females, body weight was only significantly reduced in the high-dose group, but the differences were not significant at terminal sacrifice. The body weight in females at 20 weeks (1 week before sacrifice) was approximately 400 grams, 385 grams, 382 grams, and 335 grams in the control, 375, 750, and 1500 mg/kg/day, respectively.
HAEMATOLOGY (PARENTAL ANIMALS): Haematology was not measured in the males and no effects were noted in the females.
CLINICAL CHEMISTRY (PARENTAL ANIMALS): Clinical chemistry was not measured in the males and no effects were noted in the females.
URINALYSIS (PARENTAL ANIMALS): Urinalysis was not measured in the males and no effects were noted in the females.
ORGAN WEIGHTS (PARENTAL ANIMALS): Absolute and relative liver weights were increased in mid- and high-dose females (Table 5), but were not accompanied by any histological findings.

Any other information on results incl. tables
The decreased body weight in males was probably related to nephropathy that is typically produced in male rats exposed to hydrocarbon fuels. Although there were changes in liver weight in the females, this was not accompanied by any changes in clinical chemistry or liver histopathology so is likely not of biological significance. | ||||

Applicant's summary and conclusion
- Conclusions:
- The study LOAEL for systemic effects is 1500 mg/kg/day and the NOAEL for systemic effects is 750 mg/kg/day, based on reduced body weight in dams and in pups. The LOAEL for adult males rats exposed to JP-8 orally was 750 mg/kg/day due to changes in clinical pathology, body weight, organ weights and the same irritation seen in female rats. The reproduction NOAEL was 3000 and 1500 mg/kg/day in males and females, respectively.
- Executive summary:
This was a reproductive study performed in two parts. In the first part, males were treated for 70 to 90 days with 0 (1mL of distilled water), 750, 1500, or 3000 mg/kg/day of undiluted JP-8 jet fuel, then mated to untreated females (one female at a time). Males were gavaged throughout the cohabitation period and were returned to their individual cage after successful mating. In the second part of the study, female rats were administered the test compound at doses of 0 (1mL of distilled water), 375, 750, or 1500 mg/kg/day undiluted JP-8 jet fuel for 90 -day prior to mating, through mating, gestation, delivery, and lactation for a total of 21 week. During mating, they were housed with untreated males. Litters were standardized to 4 male pups and 4 female pups on postnatal day 5. Although those pups were used for neurobehavioral tests, the data was not provided in the study report.
There were no effects on clinical signs or mortality in either sex. Haematology, clinical chemistry, and urinalysis were measured only in females without any effects noted. Body weights in male rats were decreased in a dose-dependent manner and was likely related to nephropathy that is specific in male rats treated with hydrocarbons. In females, body weight was only significantly reduced in the high-dose group. Absolute and relative liver weights were increased in mid- and high-dose females, but were not likely biologically significant due to the lack of changes in clinical chemistry or histopathology in the liver. The test compound caused perianal dermatitis (high-dose only) and stomach hyperplasia (mid- and high-dose) in the female rats (histopathology was not conducted on the males for this study because previous studies have indicated nephropathy). There were no treatment-related effects on reproduction or sperm parameters in males. There were no effects on reproduction, gestation, or litter size in females. There was a dose-related decrease in pup weight that was significant in the 750 mg/kg/day group on postnatal day 4 only and in the 1500 mg/kg/day group from postnatal day 4 through postnatal day 21 but had recovered by postnatal day 90.
The study LOAEL for systemic effects is 1500 mg/kg/day and the NOAEL for systemic effects is 750 mg/kg/day, based on reduced body weight in dams and in pups. The LOAEL for adult males rats exposed to JP-8 orally was 750 mg/kg/day due to changes in clinical pathology, body weight, organ weights and the same irritation seen in female rats.Changes in male rats may be complicated by the male rat-specific nephropathy produced after exposure to hydrocarbon fuels such as JP-4 and JP-8. The reproduction NOAEL was 3000 and 1500 mg/kg/day in males and females, respectively.
This study received a Klimisch score of 1 and is classified as reliable without restrictions because it is an acceptable and well-documented study report.
