Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

No data are available: a waiver is proposed for this endpoint. Physicochemical considerations and experimental evidence suggest that acrylonitrile is unlikely to bioaccumulate in exposed biota, and toxicity studies in mammalian species provide little evidence of cumulative toxicity in a range of species. Concentrations of acrylonitrile in biota are expected to be very low, and it is therefore concluded that the potential for secondary poisoning is very small. Bioaccumulation of acrylonitrile is not anticipated, given experimentally-derived values of 0-0.3 for the log Kow, and a bioconcentration factor (BCF) of 1.0 has been calculated from the known water solubility of acrylonitrile.
