Description of key information

Summarizing all available information the substance has been considered as non-biodegradable in freshwater and marine environment at the moment. 

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Based on all available information it has to be assumed that Benzotriazole is not readily biodegradable in freshwater and marine environement at least. Due to the incomplete report and the unclear status of the adaptation of the sludge in the OECD 302B test from Kanne no final conclusion on the biodegradability has been possible. The results of the study have indicated a relevant potential on inherent biodegradation.

With respect to all available information indicating no or minimal biodegradabilty 1H-Benzotriazole has been considered as non-biodegradable in aquatic compartment until the results of the proposed testing are available.
