Description of key information

Acrylonitrile is labile in the atmosphere, due to rapid photodegradation. The EU RAR reports a rate constant of 3.2 x 10e-12 for the reaction of acrylonitrile with hydroxyl radicals, giving an estimated half life of 5 days in the troposphere. Theoretical assessment gives similar results and a predicted half life of 4 days.
