Biotesting chronic toxicity of waters of surface sources of water service as to presence of Сeriodaphnia affinis Lilljeborg and Аllium cepa L.

Abstract

The purpose. To raise selfdescriptiveness of biotesting waters of surface sources of water service due to use of test-kit made of Ceriodaphnia affinis Lilljeborg and Allium cepa L. Methods. Biotesting the quality of waters using standard and own procedures. Results. Test-reactions on fixation of Ceriodaphnia affinis and leaf-creation of Allium cepa proved damage effect of waters of water reservoirs of river Teteriv on living organisms. Conclusions. For testing quality of waters of surface sources of water service it is offered to use test-kit made of C. affinis and A. Sulfur. On the basis of responses of test-objects indexes of toxicity are calculated which reveal specificity of responsivity of Ceriodaphnia affinis and Allium cepa on 8th and 15th day to toxic chronic effect of these waters.
