[Comparative study of the toxicity of metal chlorides and a synthetic organic molluscacide, N-tritylmorpholine, in 2 fresh-water amphipods, Gammarus pulex and Echinogammarus berilloni].
The effects of three metal salts (BaCl2, CuCl2, ZnCl2) and of N-trityl-morpholine (Triphenmorph) were studied on two aquatic amphipod species, Gammarus pulex and Echinogammarus berilloni. Experiments were made up in eucalcic and oligocalcic waters for determining the LC50 at different exposure times. The order of toxicity was the same in eucalcic water with the two species: Triphenmorph greater than Cu2+ greater than Zn2+ greater than Ba2+. This order was the same in oligocalcic water with Echinogammarus berilloni; with Gammarus pulex, CuCl2 was more toxic than Triphenmorph.
