Bulk Quote| hazards summary | Acetonitrile has many uses, including as a solvent, for spinning fibers, and in lithium batteries. It is primarily found in air from automobile exhaust and manufacturing facilities. Acute (short-term) inhalation exposure results in irritation of mucous membranes. Chronic (long-term) exposure results in central nervous system effects, such as headaches, numbness, and tremors. No data are available on its carcinogenic effects in humans. EPA has classified it as a Group D, not classifiable as to human carcinogenicity.In subchronic animal studies, histopathological liver effects occur. In a human inhalation study, all five subjects detected the odor at 40 ppm, the initial concentration of the experiment. After two or three hours, some olfactory fatigue was observed. A fatality was reported in a worker who painted for 2 days in a confined space with a resin containing 30-40% acetonitrile. Cases have been reported of children developing symptoms of cyanide poisoning within hours of drinking acetonitrile-based artificial nail remover. In reproductive studies of experimental animals, acetonitrile causes fetal skeletal abnormalities. See NITRILES. |
