Description of key information

Biodegradation in water, screening tests: 24% CO2 evolution in 28d (OECD 301B), RL1

Key value for chemical safety assessment

Additional information

In a reliable test according to OECD guideline 301B and GLP, the validity criteria of the test guideline were met (Hydrotox, 2004). After correction of the mean BOD of the Innoculum controls after 28 days, a mean degradation rate of 24.7% was found. The test item can therefore not be considered ready biodegradable.
