Test for acute toxicity of copper, cadmium and mercury to five species of marine organisms

The acute toxicity of copper, cadmium and mercury to the marine invertebrates Gammarus aequicauda, Corophium insidiosum, Idotea baltica, Sphaeroma serratum, Mytilus galloprovincialis, were evaluated by static bioassays, calculating the LC50 (lethality concentration for 50%). Hg was more toxic to Gammarus aequicauda, Corophium insidiosum, Idotea baltica, Sphaeroma serratum, Mytilus galloprovincialis than Cu and Cd. Cu was the least toxic of the metals tested.
