Essay

The thesis covers development of new principles of methodological approaches to analyse negative biological responses of environmental objects using microbial models. The factual data were received during investigation of natural waters and soils of steppe zone of south part of Odessa's region in the condition of moderate agriculture press. The main characteristics of environmental objects were determined by the microbial indices. It has established that forming genotoxic potential of natural waters depends on not only composition of pollutants and their quantities but also pH level and water hardness, and also ionic complexes of heavy metals. Genotoxic activities of ionic heavy metals combinations have been confirmed by laboratory experiments. On basis of the received results prediction model of changing microbiological indices against contributors has been developed.
