Description of key information
The inherent biodegradability of the test item was determined in the Modified MITI Test (II) with non adapted activated sludge for a period of 28 days. The study was conducted according to OECD Guideline 302 C and compliant to GLP. The test item concentration selected as appropriate was 40 mg/L, corresponding to a ThOD of 54 mgO2/L. The oxygen was depleted by respiration of bacteria and the degradation was followed by measuring the oxygen concentration. The biodegradation is therefore expressed as the percentage BOD depletion and was calculated for each study day
Two test item replicates did not reach the 10 % level (beginning of biodegradation) within the test duration of 28 days. The 3rd test item replicate reached the 10 % level after 16 days. The pass level > 70 % for evidence of inherent, ultimate biodegradability was not reached within 28 days. After 28 days the mean biodegradation rate was 5 %.
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.
