Ecological Systems and Devices Annotation << Back PROCESSES OF TECHNOGENIC CHANGE OF WATER COMMUNITIES IN THE ZONE OF INFLUENCE OF THE ENTERPRISES OF LOOSE METALPRODUCTION Yu.P. Galchenko, V.I. Lebukhov Made analytical overview of the processes of technological change in aquatic communities in the zone of infl uence of companies and alluvial metallodobychi built systematization technological factors determining zarakter digressive and depth processes of aquatic ecosystems. It is shown that the performance of various types of drainage works at construction company radically changes the conditions of reproduction as a resident and anadromous ihtnofauny. Man-made changes in water balance watercourses violates their temperature and dramatically reduces the return anadromous desiccation and freezing due to channels in the headwaters of rivers and streams. Water pollution mineral suspension violates the terms of the development of algal fl ora and has a direct negative impact on the embryos and juveniles of almost all tuvodnyh and anadromous species. And fi nally, when the inevitable development of mass placers saturation oligotrophic waters watercourses heavy metal salts dramatically reduces the quantity and quality of benthic lead to local Animal Health and promotes the growth of the number of individuals with various pathologies. It is shown that the combined effects of the groups considered anthropogenic factors can lead to an almost complete destruction of fi sh stocks in some rivers and drastically reduce fi shery value pools.
