Description of key information
No-effect levels for dissolved lead for the freshwater fish were situated between 18.9 µg Pb/L (Oncorhynchus mykiss; endpoint: scoliosis) and 1558.6 µg Pb/L (Pimephales promelas; endpoint: dry weight). The lowest selected no-effect levels for dissolved lead for the marine fish was 229.6 µg Pb/L (Cyprinodon variegatus; endpoint: dry weight).

Additional information
Since lead is the toxic component and the anions do not contribute to toxicity, all data are grouped together in a read-across approach. No-effect levels for dissolved lead for the freshwater fish were situated between 18.9 µg Pb/L (Oncorhynchus mykiss; endpoint: scoliosis) and 1558.6 µg Pb/L (Pimephales promelas; endpoint: dry weight). The lowest selected no-effect levels for dissolved lead for the marine fish was 229.6 µg Pb/L (Cyprinodon variegatus; endpoint: dry weight).
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.
