 abstract={Experiments were done on two freshwater species, Daphnia magna Straus and Dugesia tigrina Girard. The toxic effects on 3 toxic compounds, lead nitrate, lead chloride (mineral substances) and lead acetale (organic compound) were used in the studies of acute intoxication. The sensitivity of two methods, test with cut planarians and test with Daphnia magna were compared.},
 abstract={In the experiments with cut individuals, the tested chemical compounds influenced the regeneration process which lasted 10 days, this was the period of special sensitivity of planarians to the poisons. In two cases (mineral substances) the chemicalcompounds were more toxic to D. magna. Based on the classification of Liebmann (1962) the estimates were made of the degree of toxicity of poisons of the 3 tested chemical substances.},
 abstract={Two chemical compounds (lead nitrate and lead chloride) were classified within Group I of highly toxic compounds for D. magna. Lead acetate was classified within Group II of very potent poisons. In the studies with cut individuals of D. tigrina as test organism all of the tested chemical substances were classified within Group II of very potent poisons.},
