Description of key information

Tert-butyl methacrylate is not ready biodegradable, but ready biodegradable under enhanced conditions according to OECD criteria. For the risk assessment the substance was considered as inherently biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable

Additional information

The degree of biodegradation of tertiary butyl methacrylat in the Carbon Dioxide Headspace Test was not ready biodegradable, but ready biodegradable under enhanced conditions according to OECD criteria based on the quantitative determination of the formed total inorganic carbon (TIC) in comparison to the applied amount of total organic carbon (TOC). The required pass level of degree of enhanced ready biodegradation of 60 % TIC/TOC at the end of exposure was fulfilled. For the risk assessment the substance was considered as inherently biodegradable.
