Description of key information

In a valid guideline study according to OECD 301 F (manometric respiratory test) 4-(Methacryloyloxy)benzophenone was exposed to microorganisms derived from activated sludge of a muncipal sewage treatment plant under aerobic static conditions. The biodegradability of 4-(Methacryloyloxy)benzophenone was determined to be 78 % after 28 days based on O2 consumption as compared to the theoretical O2 demand (ThOD). The positive control sodium benzoate reached 86% biodegradation after 14 days, confirming of suitability of inoculum and test conditions.

Since 4-(Methacryloyloxy)benzophenone reached 67 % of degradation at the end of the 10 -d window it reached the pass level of 60 % for ready biodegradability and is therefore classified as ready biodegradable in the Manometric Respiratory Test.
