Endpoint summary
Administrative data
Description of key information
Overall, the data available include 13 chronic endpoints, from 11 species, which cover at least 8 taxonomic groups. Based on these long-terms NOECs (using the geometric means for endpoints from the same species) the HC5 is 0.064 mg Mn/L (with 50% confidence limits of 0.031 and 0.131 mg Mn/L).
Short-term toxicity
For acute toxicity to fish, seven reliable studies are available. The lowest 96-h LC50 of 3.17 mg Mn/L was evaluated for rainbow trout (Oncorrhynchus mykis), as measured by mortality.
For acute toxicity of manganese to aquatic invertebrates four reliable studies were identified. The lowest of which is an LC50 of 3.0 mg Mn/L from a study on Hyalella azteca.
Two reliable studies for acute toxicity on algae are available. The lowest 72 -h EC50 for algal growth rate was > 7.8 mg Mn/L.
Long-term toxicity
For chronic toxicity to fish, six reliable studies are available. The lowest NOEC/EC10 of 0.6 mg Mn/L was evaluated for rainbow trout (Oncorrhynchus mykis) in a 4 months study.
For chronic toxicity to aquatic invertebrates three reliable freshwater studies were identified. The lowest of which resulted in a 60-d NOEC of 0.01 mg Mn/L from a study on Giant river prawns (Macrobrachium rosenbergii).
Two reliable studies for chronic toxicity on algae are available. The lowest 72 -h NOEC for algal growth rate was 1 mg test substance/L, corresponding to 0.325 mg Mn/L.
Additional information
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.
