Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Chronic endpoints are available for two sediment dwelling organisms, Hyalella Azteca and Chironomus tentans, representing different living and feeding conditions. Effect concentrations for sediment toxicity are expressed as manganese concentration of the overlaying water, and the lowest of these endpoints is a NOEC of 0.29 mg Mn/L.
Since effect concentrations for sediment toxicity are expressed as mangenese concentration of the overlaying water, the concentration is converted to sediment concentrations applying the equilibrium partitioning method (EPM) and the suspended matter-water partitioning coefficient Kp of 5960 L/kg. This results in a NOEC of 1729 mg Mn/kg dw.
Key value for chemical safety assessment
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.
