Description of key information
Biodegradation of cloquintocet-mexyl has been investigated in water, water/sediment systems and soil.
Biodegradation of cloquintocet-mexyl was observed in a screening test, but the substance was rated as “not readily biodegradable”. Cloquintocet-mexyl rapidly degraded in aerobic and anaerobic water/sediment systems, but slowly degraded in sterile condition. The half-lives of cloquintocet-mexyl in the water and the sediment phase were found to be 0.2 and 0.7 days, respectively.
Biodegradation in soil under aerobic conditions was very fast (DT50 from 0.2 to 2.4 days, depending on soil types and experimental conditions), while cloquintocet-mexyl persisted in anaerobic/sterile conditions.
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.
