Additional information
A reliable study of acute toxicity to aquatic invertebrates is available, using Daphnia magna. This study included supporting analysis and demonstrated that actual exposure levels were maintained close to nominal values. After 48h all Daphnia were observed to be immobilised at 82 mg/l while only 5% Daphnia were immobilised at 46 mg/l (mean measured concentrations). The EC50 value was determined to be 58 mg/l, based on mean measured concentrations of the active ingredient.
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.
