Description of key information

C9 -11 Methacrylate was tested for ready biodegradability in the Carbon Dioxide Evolution Test (OECD 301B). The test concentration was 20 mg/L TOC nominal, equiv. to approx. 26 mg/L test substance. Activated sludge from a municipal sewage plant were used (municipal waste water treatment plant Mannheim, Germany). Based on the rate of biodegradation of 80-90 % CO2/ThCO2 at the end of exposure the test substance can be evaluated as readily biodegradable in this test.
