Biodegradation

Biodegradation in water: screening test

The ready biodegradability of the test substance was examined in a test (BASF SE, 2017) according to the OECD 301 B (CO2 evolution, modified Sturm test). After 28 days the test substance was biodegraded by an average of < 10 % CO2/ThCO2. Therefore, the required pass level for ready biodegradability within a ten day window was not reached and the test substance was found to be not readily-biodegradable under the test conditions.
