Description of key information

In accordance with section 1 of REACH Annex XI, the study on long-term toxicity to fish for iron oxides does not need to be conducted. Natural baseline iron concentrations in the aquatic environment are already much higher than the reported saturation concentrations of iron oxides in the environment (Arche 2010). As such it is unlikely that iron ions released from iron oxides would inhibit growth and proliferation of aquatic plants, animals or microorganisms. Additionally, studies are presented with read across from soluble iron substances. For LEAD: 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).
