Description of key information
The biodegradability of Glycerolformal methacrylate exposed to microorganisms derived from activated sludge of a municipal sewage treatment plant was investigated under aerobic static exposure conditions using the Manometric
Respirometry Test OECD 301F.
Biodegradation of Glycerolformal methacrylate based on O2 consumption was calculated to be 40% after 28 days, as compared to the theoretical oxygen demand (ThOD).
The biodegradation of Glycerolformal methacrylate reached 32% at the end of the 10-d window. Biodegradation of the test item was observed after a lag phase of about 1 day.
The procedure control sodium benzoate reached 77% biodegradation after 14 days, thus confirming the suitability of the inoculum and of the test conditions.
The calculated biodegradation based on DOC measurement reached 37% for Glycerolformal methacrylate and 100% for sodium benzoate. The data essentially confirm the limited biodegradability of the test item.
Glycerolformal methacrylate did not reach the pass level of 60% for ready biodegradability in the Manometric Respirometry Test, neither within the 10-d window nor after 28 days of incubation and, therefore, cannot be termed as readily biodegradable.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
