T1 Methodic Approaches to Identification of the Toxic Compounds Class in the Bottom Sediments of the Fresh Water Bodies JF Hydrobiological Journal JO HYD YR 2018 FD 2018-11-14 VO 54 IS 6 SP 94 OP 103 K1 identification of pollutant's class K1 toxicity K1 bottom sediments K1 Chironomus riparius K1 Daphnia magna AB Paper describes experience of application of the method of identification of contaminants' class, which cause the bottom sediments toxicity for the benthic and planktonic invertebrates owing to the secondary water pollution. The method consists in study of the test-organisms responses to adding of the substances capable of binding of contaminants of the certain chemical class. This enables identification of the contaminants' class in a series of experiments. Possibility to use Chironomus riparius larvae and Daphnia magna juveniles for identification the freshwater sediments toxicity was substantiated.
