Description of key information

A study was performed to assess the ready biodegradability of the test item in an aerobic aqueous medium. The method followed was designed to be compatible with the OECD Guidelines for Testing of Chemicals (1992) No. 301B, "Ready Biodegradability; CO2Evolution 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)).

The test item attained 1% biodegradation after 28 days and therefore cannot be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No. 301B.

Care should be taken in the interpretation of the results due to the inhibitory nature of the test item to the activated sewage sludge micro-organisms used in the study. It should also be noted that the test substance is a UVCB containing multiple carbon chain components and as a consequence current biodegradation tests may not be appropriate.
