Description of key information

The high quality chronic freshwater sediment database contains toxicity data towards lead for 7 different sediment dwelling species (Tubifex tubifex, Ephoron virgo, Hyalella azteca, Gammarus pulex, Lumbriculus variegatus, Hexagenia limbata, Chironomus tentans). Selected EC10/NOEC levels for lead were situated between 573 mg Pb/kg (Tubifex tubifex; endpoint: reproduction) and 3390 mg Pb/kg (Chironomus dilutus; endpoint: survival).


The chronic toxicity database for marine sediment dwelling organisms contains toxicity data for 2 marine species (Neanthes arenaceodentata and Leptocheirus plumulosus). Selected no-effect levels for lead were situated between 680 mg Pb/kg (Neanthes arenaceodentata; endpoint: growth) and 1291 mg Pb/kg (Leptocheirus plumulosus; endpoint: growth).
