[Interest of some biological criteria in studying daphnids contaminated by cadmium nitrate (author's transl)].
Three biological criteria were studied on daphnids after 28 days of contamination with three different concentrations of cadmium (5, 10, 15 micrograms/l), such as mortality, dry weight and reproduction rate relative to general metabolic state of the crustacea. The value of Cl50-28 exceed 15 micrograms/l for dry weight and mortality determinations, on the other hand it is only 10 micrograms/l for reproduction rate. The latter appears as the most sensible criteria.
