Description of key information

Biodegradation: Key study. Test method according to OECD 301 B (modified Sturm test). GLP study. The test item is not readily biodegradable.

Additional information

Biodegradation: A screening test for biodegradation in water was conducted in accordance to OECD 301 B - CO2 evolution (Modified Sturm test) under GLP conditions with the test item. The test included 2 replicate of blank controls, 2 replicates of the test suspension, a positive control (sodium acetate) and a toxicity control. The relative degradation calculated from cumulative measurements performed until day 29 of the test revealed 14 and 34 % degradation of the test substance in the replicates. The substance cannot be regarded as ready biodegradable.However, the average of degradation (24 %) could be regarded as evidence of inherent primary biodegradability.
