Additional information
Two studies on short-term toxicity to aquatic invertebrates are available. The study performed in 1994 was conducted according to the OECD Guideline 202 and reports a 48h-EC50 to Daphnia of 16 mg/L (based on nominal concentrations). However, the test material identification was not sufficiently detailed to assess the study as reliable without restrictions and can allow misleading interpretation. Therefore, the short-term toxicity to aquatic invertebrates was repeated in 2010. The new study (2010) reports a 48h-EC50 of 47 mg/L expressed as active content and a 48h-EC50 of 71 mg/L as test material (both based on nominal concentrations). This study is considered to have a reliability of (1).
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.
