Description of key information

The high quality chronic database contains freshwater toxicity data for 2 rotifer species (Philodina rapida; Brachionus calyciflorus), 1 insect (Chironomus tentans), 2 mollusc species (Lymnaea palustris; Lymnaea stagnalis) and 5 crustacean species (Hyalella azteca, Daphnia magna, Ceriodaphnia dubia, Diaphanosoma birgei, Alona rectangula). Chronic freshwater no-effect levels for dissolved lead for invertebrates were situated between 1.7 µg Pb/L (Lymnaea stagnalis; endpoint: growth) and 495.7 µg Pb/L (Ceriodaphnia dubia; endpoint: mortality). Chronic marine NOEC/L(E)C10 values are available for 2 echinoderms (Strongylocentrotus purpuratus, Dendraster excentricus), 3 bivalve molluscs (Mytilus galloprovincialis, Mytilus trossolus, Crassostrea gigas) and 1 annelid (Neanthes arenaceodentata). No-effect levels for dissolved lead for marine invertebrates were situated between 9.2 µg Pb/L (Mytilus trossolus; endpoint: abnormalities) and 1409.6 µg Pb/L (Mytilus galloprovincialis; endpoint: mortality).
