- Conclusions:

- Executive summary:
Data available for the target chemicals was reviewed to determine the toxic nature of the test chemical Benzene-1,4-diammonium sulphate (16245-77-5). The studies are as mentioned below:
Two generation reproduction toxicity study of test chemical was performed on male and female Sprague Dawley Him:OFA rats according to OECD 416 Guideline. 0, 5, 15 and 45 mg/kg bw/d in deionised water, 50 μl 25 % ammonia per g test substance added and administered by oral gavage route to males for 70 days and to females for 14 days until mating. The animals were monogamously mated within the dose groups. Dams were further dosed until weaning of the pubs. Starting on day 21 after birth the F1 generation was dosed for approximately 80 d. After mating the F2 generation was kept until weaning. 24 male and 24 female were placed each dose level. The common parameters were evaluated (female sexual cycle, mating, insemination, gravidity, birth and litter data, postnatal weight and physiological development). Histopathology was performed for organs with obvious abnormalities, for parents without live offspring and for all parent animals of the control and the highest dose group. The reproduction organs (pituitary gland, mamma, vulva, vagina, cervix, uterus, tubes, ovaries, penis, testes, epididymides, ducti referentes, coagulation gland, prostate gland, vesicular gland) were examined microscopically. 4 animals (one of P- and 3 of F1-generation) died due to intubation-induced lesions. Body weight development, feed consumption and observation of the animals did not show substance treatment related differences. Observations and measurements in the pups of both generations until weaning did not show differences in the parameters evaluated. No detrimental effect on male and female fertility was found. Hence No Observed Adverse Effect Level (NOAEL) was considered to be 45 mg/kg/day, when male and female Sprague Dawley rats were treated with test chemical orally.
The reproductive and developmental toxicity study of test chemical was performed in female New Zealand White Rabbit. The test material dissolved in distilled water and administered in dose concentration 0, 10, 25, 50 mg/kg bw/d, by oral gavage route from day 6 to 18 of gestation while positive control Vitamin A in rape seed oil in dose concentration 6 mg/kg bw/d given by same route. The females were fertilised by natural mating. After coitus HCG was given i.v. to ensure ovulation. The animals were examined daily for mortality and clinical signs. The body weights were determined on days 0, 6, 18 and 28 of gestation. On day 28 of gestation the animals were sacrificed, the foetuses were dissected and examined for congenital abnormalities and macroscopic changes. The common section parameters were recorded. Half of the foetuses were examined for skeletal and the other half for visceral abnormalities. 1 female at 10 and 1 female at 25 mg/kg bw/d died, at 50 mg/kg 3 females died presumably because of the intubation procedure. No clinical signs were observed. Body weights of the females in the dose groups were similar to the controls. The changes in the incidences of intrauterine death observed were not dose-related. The number and sex of the foetuses as well as the foetal body weights were not influenced by substance treatment. The frequencies of external abnormalities, visceral malformations and variations as well as skeletal defects exhibited no substance-related changes. The positive control (Vitamin A) did not show teratogenicity and only slight embryotoxicity. Hence No Observed Adverse Effect Level (NOAEL) for maternal toxicity and embryotoxicity was considered to be 50 mg/kg/day. When female New Zealand White Rabbit were treated with test chemical orally from day 6 to 18 of gestation.
