Description of key information
Additional information
A field study has been carried out, to monitor the impact of cloquintocet-mexyl and its relevant metabolites on shallow groundwaters and adjacent surface waters. The study was GLP-compliant and is considered to be acceptable with restrictions (2) as a field study is specific to the sites studied and weather conditions experienced during the study period.
The concentrations of Cloquintocet-mexyl (CGA 185072) and its metabolite CGA 153433 were monitored in soil and water samples in a field study at a sandy and clay site. A single application was made in December 1997 at each site and samples were taken at predetermined times or when triggered by rainfall events. Neither cloquintocet-mexyl nor its metabolite were detected above the limit of detection in any water sample taken during the field trial. Both compounds were detected in the soil samples, but only in the samples from 0 - 5 cm depth. Concentrations had fallen to below the limit of detection after 1 month in the clay soil, and after 14 days and 6 months for the parent and metabolite respectively in the sand soil.
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.
