title: [Sensitivity of the prosobranch mollusk Potamopyrgus jenkinsi Smith to the action of metallic chlorides (ZnCl2, BaCl2, CuCl2) and to the synthetic molluscacide N-tritylmorpholine].
abstract: The toxicity of 3 metal chlorides (ZnCl2, BaCl2, CuCl2), and of N-trityl-morpholine (Triphenmorph or frescon) has been studied on the gastropod mollusc Potamopyrgus jenkinsi, in eucalcic and oligocalcic waters. The results showed the following order in the efficiency of the toxic compounds: triphenmorph greater than copper greater than barium greater than zinc. In eucalcic water, the toxicity of barium and decreased whereas the efficiency of triphenmorph and increased. The toxicity of the substances, at middle term, rose in relation to the time of the experiment. An exposure of 2 h to the toxic agents was sufficient to induce high mortality in P jenkinsi. In oligocalcic water, the juvenile snails were more sensitive than the adults to the action of metal chlorides, but they showed higher tolerance to Triphenmorph; in addition, the winter generation was more resistant than the summer one, except for barium.
