| toxicity summary | IDENTIFICATION AND USE: Acetamide is a solid. It is used as a solvent and stabilizer, accelerator in the estimation of bilirubin, antidote against monofluoroacetamide poisoning, and humectant for paper. HUMAN EXPOSURE AND TOXICITY: There are no data available. ANIMAL STUDIES: When acetamide was administered at a concentration of 5% in the diet to 99 male rats, with 2 rats returned to a control diet each week, liver tumors were found after treatment for 14-40 weeks in 22/81 rats. Acetamide-treated rats developed neoplastic nodules and hepatocellular carcinomas. The incidence, speed of onset, and frequency of metastases were greater in males than in females. Acetamide had the least toxic effects in regards to teratogenicity and embryotoxicity, compared to its derivatives. Acetamide produced morphological transformation in Syrian hamster embryo cells without metabolic activation. ECOTOXICITY STUDIES: Acetamide exhibited a selective damaging action on Entosiphon sulcatum. |
