Description of key information
Biodegradation screening test, OECD 301B, aerobic, activated sludge: 4% degradation (CO2 evolution) after 28 days, not readily biodegradable
Additional information
Biodegradation in water. screening tests
A 28 day study key study (Bayliss, 2016) was performed to assess the ready bioavailability of the test substance in an aerobic aquaeous medium. The method followed the OECD Guidelines for Testing of Chemicals (1992) No. 301B, "Ready Biodegradability; CO2 Evolution Test" referenced as Method C.4-C of Commission Regulation (EC) No. 440/2008 and US EPA Fate, Transport, and Transformation Test Guidelines OCSPP 835.3110 (Paragraph (m)) and was conducted in compliance with GLP criteria.
The test substance attained 4% biodegradation after 28 days. The results obtained from the mineral oil vessels showed 37% degradation over the test period. Correction of the biodegradation rate of the test substance for mineral oil degradation showed that the test substance achieved 0% biodegradation after 28 days. The test substance therefore cannot be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No. 301B.
Biodegradation in water and sediment: simulation test
No information available. In accordance with REACH Regulation (EC) 1907/2006, no data about biodegradation in water and sediment (simulation tests) is required.
Biodegradation in soil
No information available. In accordance with REACH Regulation (EC) 1907/2006, no data about biodegradation in soil is required.
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.
