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).
