Biowin prediction indicates ethylene is expected to be readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

As ethylene is a gas at standard temperature and pressure conducting a standard ready biodegradability test is technically difficult and based on exposure estimates the test may not be relevant. Therefore, the use of a QSAR to predict the biodegradability of ethylene is an appropriate technique to use as part of a weight of evidence approach. The use of Biowin (Howard et al. 1992) is appropriate for ethylene as this compound falls within the applicability domain of the model. The Biowin prediction indicates that ethylene is expected to be readily biodegradable.
