Description of key information
In a biodegradation screening study (OECD TG 301D), after 28 days exposure of secondary activated sludge to 2 mg/L of the substance, 0% biodegradation was observed. Prolongation of this study to 60 days resulted in 7% degradation. Based on these findings the substance is considered to be not readily biodegradable. In a follow-up study, the biodegradation of the substance was tested using an enhanced Closed Bottle Test (OECD TG 301D) in which the inoculum was acclimatised using a semi-continuous activated sludge (SCAS) unit (according to OECD TG 302A). In this study biodegradation did not exceed 20% after 42 days exposure to adapted activated sludge. These findings confirm the non-ready biodegradability of the substance.
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.
