Additional information
Long-term toxicity to aquatic invertebrates is not a standard information requirement in Annex VIII of Regulation (EC) No 1907/2006. However, for Mn-EDTA (MnEDTANa2, CAS 15375-84-5), one of the two main components of the UVCB, a long-term toxicity study on the reproduction of the water flea Daphnia magna is available [Akzo Nobel, 2010]. The study was conducted according to OECD guideline 211 under GLP conditions. In this test, parental weight was found to be the most sensitive endpoint based on the EC10 values. An EC10 and EC50 for parental weight were determined at 91.9 mg/L and 397 mg/L, respectively. The EC10 and EC50 for reproduction were 198 mg/L and 365 mg/L, respectively.
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.
