EFFECT OF COAL MINES WASTEWATERS ON THE QUALITY OF WATER OF THE OLKHOVAYA RIVER
A study was made of a separate section of the Olkhovaya river channel, which was subjected to intensive pollution by sludge and mine runoff. As part of the study analyzed the physicochemical composition of water samples and analyzed the state of phytoplankton based on the analysis of chlorophyll fluorescence induction curves using the method of fluorimetry. The negative effect of sludge wastes on the biomass of phytoplankton of the Olkhovaya river, as well as the photosynthesis rate of microalgae is shown. A number of test functions that most effectively reflect the degree of pollution effect on biota are selected.
