Description of key information

The high quality chronic database for lead contains freshwater toxicity data for two rotifer species (B. calyciflorus; P. rapida), three insects (B. tricaudus; C. tentans; C. riparius), three mollusc species (L. stagnalis; L. palustris; L. silliquoidea), five crustacean species (C. dubia; D. magna; H. azteca; D. birgei; A. rectangula). The chronic freshwater no-effect levels for these invertebrates were situated between 0.48 µg dissolved Pb/L (Lymnaea stagnalis; endpoint: reproduction) and 963 µg dissolved Pb/L (Chironomus riparius; endpoint: mortality).

Chronic marine NOEC/L(E)C10 values are available for three echinoderms (Strongylocentrotus purpuratus, Dendraster excentricus, Paracentrotus lividus), five bivalve molluscs (Mytilus galloprovincialis, Mytilus trossolus, Perna viridis, Crassostrea gigas, Ruditapes decussatus), one annelid (Neanthes arenaceodentata), two crustaceans (Americamysis bahia, Penaeus monodon), and one copepod (Tisbe battagliai). No-effect levels for dissolved lead for marine invertebrates were situated between 9.2 µg dissolved Pb/L (Mytilus trossolus; endpoint: development) and 1409.6 µg dissolved Pb/L (Mytilus galloprovincialis; endpoint: mortality).
