Description of key information

Not readily biodegradable: 18% (ThCO2) in 28 days (OECD 301 B)

Key value for chemical safety assessment

Additional information

One study on the ready biodegradability of the substance carried out according to GLP and OECD guideline 301 B is available (Mead, 1999). The study used activated sludge from a sewage treatment plant treating predominantly domestic sewage and 25.4 mg/L of test material, corresponding to 10 mg TOC/L. The test substance reached 18% degradation within 28 days while the reference substance attained 74% and the toxicity control 75% degradation. Thus, the test substance can be classified as not readily biodegradable under OECD conditions.
