Inst. Occup. Safety Health, ). Acrylonitrile (CH ₂ =CHCN) is a toxic, colorless to pale-yellow liquid, harmful to the eyes, skin, lungs, and nervous system. It may cause cancer. Workers may be harmed from exposure to acrylonitrile. The level of exposure depends upon the dose, duration, and work being done.

Acrylonitrile is. Acrylonitrile is used as feedstock for the production of products such as acrylamide, acrylic fibers, adiponitrile, ABS and SAN resins, nitrile rubber.

INDIAN SCENARIO. Reliance Industries Ltd., is the only producer of acrylonitrile in India. Installed capacity: 41, metric tonne per annum.

Generally, if people are exposed to acrylonitrile it is through air, and in general, its levels in outdoor air are so low that they are below the detection limit. Environmental exposure to acrylonitrile in air is expected to be greatest near industrial point sources.

Tobacco smoke is known to be a source of acrylonitrile to indoor air. The major use of acrylonitrile is the manufacture of copolymers for the production of acrylic and modacryclic fibers by copoly- merization with methyl acrylate, methyl methacrylate, vinyl acetate, vinyl chloride, or vinylidene chloride [National Institute for Occupational Safety and Health (NIOSH), ].
