Description of key information

The high quality chronic freshwater database contains toxicity data towards lead for 6 freshwater fish species (Oncorhynchus mykiss, Salvelinus fontinalis, Pimephales promelas, Lepomis macrochirus, Salvelinus namaycush, Ictalurus punctatus, Salmo salar). No-effect levels for dissolved lead for 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 chronic toxicity database for marine fish contains toxicity data for 1 marine fish (Cyprinodon variegatus). The lowest selected no-effect levels for dissolved lead for this marine fish was 229.6 µg Pb/L (Cyprinodon variegatus; endpoint: dry weight). 

Key value for chemical safety assessment

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