Критические параметры негативного воздействия на экосистему озера Байкал и основные направления улучшения его экологического состояния

Negative impact limits on the ecosystem of the Lake Baikal identified based on an algorithm developed by the authors for determining hazardous substances to this ecosystem have been studied. The current standards of maximum permissible impacts on the unique ecological system of the Lake Baikal have been studied, this analytical review and methods of their determination has allowed to identify the necessity of their improvement. As the result of wastewater composition and properties analysis, pollutants have been established which are represented by chemical substances and microorganisms, subject to be taken into account for ecological rationing. Based on the proposed algorithm, ration limits of hazardous substances in wastewater are determined for discharging into the Lake Baikal, limits of hazardous substances in wastewater run-off whitin water bodies of the central and buffer ecological zones of the Lake Baikal territory, the permissible substances mass discharged into the depressions of the Lake Baikal. As a result of the studies, recommendations were elaborated for regulating the negative impact on the water bodies of the Lake Baikal territory and for improving the ecological situation of the Lake Baikal.
