Determination of chronic toxicity of waters of surface sources of water service on Daphnia magna Straus and Тradescantia fluminensis Vellozо

Abstract

Determination of chronic toxicity of waters of surface sources of water service on Daphnia magna Straus and Тradescantia fluminensis Vellozо The purpose. To raise selfdescriptiveness of biotesting of waters of surface sources of water service due to use of test-kit from Daphnia magna Straus and Tradescantia fluminensis Vellozo. Methods. Biotesting of quality of water according to standard and own procedures. Results. In researches on the test-reactions of fixation of daphnes and root-creation of spiderwort the ill effect on living organisms of waters of water reservoirs of river Teterev is specified. Conclusions. For biotesting of quality of waters of surface sources of water service it is offered to use test-kit from D. magna and T. fluminensis. On the basis of responses of test-objects the indexes of toxicity are calculated. Specificity is revealed of responsivity of spiderwort (on 8th day) and daphnes (on 15th day) to toxic chronic influence of these waters.
