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).

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater fish:
18.9 µg/L
EC10, LC10 or NOEC for marine water fish:
229.6 µg/L

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).
