Description of key information

No simulation tests on the biodegradation of the test substance in water and sediments are available.

Key value for chemical safety assessment

Additional information

No data on the biodegradation of the test item in water and sediments are available. However, further biotic degradation testing shall be proposed if the chemical safety assessment according to Annex I indicates the need to investigate further degradation of the substance and its degradation products. The test substance was found to be non-biodegradable in a GLP guideline study according to the EU method C.4 (CO2 evolution test). Due to the results of these tests it is assumed that the results of simulation studies would not reveal any different findings. Therefore, simulation studies in surface water and sediment are not performed.
