Acrylonitrile is a fumigant insecticide and is now considered obsolete. It is highly soluble in water and miscible with most organic solvents. It has a high potential for leaching to groundwater. It is not expected to be persistent in soil systems. Acrylonitrile has a high mammalian toxicity and is carcinogenic. It is also a mutagen which may also cause adverse reproduction &/or development effects. Little is known about its ecotoxicology but it is moderately toxic to fish and aquatic invertebrates.
Data alerts
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
