Description of key information
The substance was not readily biodegradable under the conditions of a modified MITI test according to OECD guideline 301 C (BASF, 09G0580/09G205, 2016).
Key value for chemical safety assessment
Additional information
For the determination of the aerobic biodegradability of the test substance in water a modified MITI test according to OECD guideline 301 C was conducted (BASF, 09G0580/09G205, 2016). Mixtures of the test substance, a defined mineral medium and non-adapted, aerobic sludge from several samples were incubated and aerated under static conditions in a respirometer for 28 days. The mean degree of biodegradation of the test substance was 4% BOD/ThOD after an exposure period of 28 days. The results derived from specific analysis show that the test substance had a dissipation degree at the end of exposure of 25% related to the test substance content in the blank control and 98.0% related to the test substance concent in the blank control at the start of exposure. Thus, the test substance is not readily biodegradable under the conditions of this test.
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.
