Environmental Impact Methylacrylonitrile can be released to the environment in gaseous and wastewater effluents at sites of its commercial production. If released to water, methylacrylonitrile can be physically removed via volatilization. If released to soil, methylacrylonitrile may leach readily based upon an estimated Koc value of 18.3.
Insufficient data are available to predict the importance of microbial degradation in soil or water.
Occupational exposure to methylacrylonitrile can occur through inhalation, dermal exposure, or ingestion. Inhalation is expected to be the major route of occupational exposure. Very little is known about the fate of methylacrylonitrile in soil. It has a relatively high vapor pressure of 71.2 mm Hg at 25 deg C which indicates that evaporation from terrestrial surfaces is likely to occur. Insufficient data are available to predict the importance of abiotic or microbial degradation in soil.
