Statistics:

2. To determine effects on maternal body weight, the mean and standard error were calculated for each experimental group, and values of t_ were obtained for test and control group differences in means. Fetal values were analysed with the litter as the basic unit. The proportion (p_) of litter having a particular attribute was calculated and transformed to a normally distributed variable arc sin/p_ value . The mean and standard error of these values for various.test groups were then derived . The t_ test was used for comparison of test and the respective control values.

Executive summary:

Various studies have been reviewed to determine the reproductive toxicity potential of the test chemical. These include in vivo experimental studies performed on rats for the test chemicals. The results are mentioned below:

Teratogenicity studies were conducted in rats treated orally from days 6-15 of gestation with single daily doses of the test chemical. Pregnant female Wistar rats (20 per group) received the following test doses of the test chemical suspended in com oil once per day by esophageal intubation: 0, 125, 250, or 500 mg/kg from day 6 to 15 of gestation. On the 22nd day of gestation, dams were killed and uterine contents were removed and analyzed . Females were weighed at frequent intervals during gestation. On the 22nd day of gestation, each dam was killed, its uterine contents removed, its number of corpora lutea determined, and was then necropsied. The fetuses were weighed and examined for viability nd external malformations. Early resorptions or implantation sites and fetuses dying at a late stage in their development, were recorded. Two-thirds of the live fetuses from each litter were examined for skeletal development after alizarin red staining. The remainder, fixed in Bouin's fluid, were dissected to study visceral anomalies. No signs of toxicity or any adverse effects were seen in the dams . Resorption of fetuses at 125 mg/kg was increased, although not significantly. The incidence of anomalous fetuses in the 250 mg/kg group was borderline significant (p--0 .05). It was noted that this was most likely not significant in relation to the absence of significant findings in the 500 mg/kg dose group. Hence, the NOAEL can be considered to be 500 mg/kg/day for maternal rats and fetus.

This result is supported by a multi-generational study performed to determine the toxicity potential of the test chemical.Groups of Wistar (Chbb=Thom (SPF)) rats (24 of each sex per group) received diets containing the test chemical at 0, 1000, 4000 or 12 000 ppm. Achieved intakes were reported to be approximately 0, 96, 381 and 1180 mg/kg bw per day at 0, 1000, 4000 and 12 000 ppm, respectively. There were two litters in the first generation and one in the second. Parents were mated 1:1 after approximately 10 weeks of exposure to the test chemical for the F1a and F2a litters. For the F1b mating, parents were paired 10 days after weaning of the F1a pups. Litters were not culled on day 4 postpartum. Clinical signs, body weights, feed consumption, mating parameters, gestation and delivery parameters, pup survival, and physical and behavioural development (ear and eye opening, grip strength and pupillary reflex) were recorded. No evaluation of date of sexual maturation was included in the protocol. A gross necropsy examination was performed on all pups not selected for mating. Further examinations were performed on any pups found dead or dying or showing macroscopic changes. All parental animals were necropsied after weaning of their offspring and subjected to pathological examination.There was no effect on mating, fertility, pregnancy outcome, litter size or pup survival. Significant reductions in maternal body weight gain were seen in males and in females during pregnancy and lactation at 12 000 ppm in the F1 matings. Pup body weights were similar to control values at birth, but were significantly lower by day 21 at 12 000 ppm in all generations. Examinations of pups and parental animals did not identify any adverse effects of the test chemical administration. Attainment of physical developmental markers and behavioural results were similar in all groups of pups. Top-dose female, but not male, parents had an increased incidence of nephritis in both generations, but a reduction in calcification in F1 parents. There were no adverse findings in the reproductive organs. The NOAEL for reproductive toxicity was 12 000 ppm (equivalent to 1180 mg/kg bw per day), the highest dose tested.

Based on the available results and applying the weight of evidence approach, the NOAEL for maternal animals and fetus can be considered to be 1180 mg/kg/day. Hence, the test chemical can be considered to non-reprotoxic and classified under the category “Not Classified” as per CLP Regulation.
