Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Not readily biodegradable according to OECD criteria. Moderately eliminated from water.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Several studies are available for the biodegradation assessment of the test substance.
In an OECD 301A study the substance was found to be not readily biodegradable based on a DOC removal of 0% in 28 days (Ciba-Geigy 1992).
Furthermore, two studies investigating the inherent biodegradability of the test item are available. The oxygen consumption in a study according to OECD 302C (Ciba-Geigy 1991) was measured to be 0% which substantiates the results of the OECD301A study. The second study on inherent biodegradability (OECD 302B) determined a biodegradation of 43.7% based on DOC removal after 28 days (Ciba-Geigy 1992). Hence, the test substance is moderately eliminated from water.
