Additional information
Three studies (one with a freshwater and two with a saltwater species) are available for this endpoint. All are considered to be relevant, reliable, adequate for risk assessment, and adequate for classification purposes. The two saltwater species belong to differt taxonomic groups (mysid: phylum arthropoda - subphylum crustacea, eastern oyster: phylum mollusca). The EC50/LC50 results are carried forward for risk assessment purposes.
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.
