Acrylonitrile is degraded in the atmosphere, in water and in soil. The
EU RAR reports half-lives of 5 days, 150 days and 300 days respectively
for the troposphere, surface water and soil; however reported values of
2 -30 days for surface water and 6 days for soil are also noted.
Photolytic degradation in surface water has also been reported.
Acrylonitrile is hydrolytically stable.
Acrylonitrile does not meet the criteria for readily biodegradable, but
can be considered inherently biodegradable based on the results of
experimental studies. In practice, rapid biodegradation of acrylonitrile
is noted in acclimated WWTP. Biodegradation of acrylonitrile by soil
bacteria is also noted.
No data are available for bioaccumulation, however physicochemical
properties (water solubility, log Kow) of the substance and experimental
evidence suggest that acrylonitrile is unlikely to bioaccumulate in
Transport and distribution
Calculated Koc values, experimental data and the water solubility of the
substance indicate that there is little potential for the adsorption of
acrylonitrile to soil or sediments. Acrylonitrile can be regarded as a
moderately volatile compound, based on the calculated Henry's Law
constant of 9.6 Pa/m3/mol-1.
