Based on the lower live litter size on PND 0 for F2 pups, decreased postnatal survival, and lower mean body weights and body weight gains during the pre-weaning period for F1 and F2 pups at 400 mg/kg/day, the NOAEL for neonatal toxicity was considered to be 100 mg/kg/day. (europa.eu)
mice developed severe liver toxicity, which probably tio is less than 1, while in mouse liver the ratio is about contributed to the cause of death. (cdc.gov)
