Additional information
The key study was chosen on the basis that it is a reliable, well reported study conducted in accordance with recognised OECD and EU guidelines and also to GLP standard. In addition, the purity of the test substance was 99.66% dimethyltin dichloride and the species used were Daphnia magna, the most typical species used to address this endpoint.
All of the supporting studies gave EC50 values in the range of 10 - 100 mg/L, which would lead to the same CLP classification as the key study, although most were only conducted for 24 hours.
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.
