The draft Toxicological Review of Acrylonitrile provides scientific support and rationale for the hazard and dose-response assessment pertaining to chronic exposure to acrylonitrile. Acrylonitrile is widely used in the production of acrylic fibers, plastics (acrylonitrile butadiene styrene and acrylonitrile-styrene resins), and nitrile rubbers, and as an intermediate in the production of other chemicals. Exposures most relevant to the public are inhalation of emitted acrylonitrile in the vicinity of industrial sources, and ingestion of acrylonitrile monomer migrated from plastic containers into food and drink.
