DISTRIBUTION OF HEAVY METALS ON THE DEPOSIT AREAS IN THE ZONE OF HEAT-POWER PLANTS IMPACT
The problem of chemical contamination of the environment with heavy metals in the areas adjacent to the stationary sources of pollutants emission is considered in the article. The priority stationary source of environment pollution in the city of Kumertau, Republic of Bashkortostan is Kumertau HPS (heat-power station). The examination of lignite fly-ash of the Kumertau HPS has shown that it contains heavy metals. Through the system of liquid slag disposal the ashes get into the dumps and then in the objects of environment of the adjoining territories, soil and plants including. The content of zinc, lead, copper and manganese ions in melt and rain water, soil and knotweed grass has been determined. The elemental analysis of the vegetative material collected on the territories, adjacent to the ash-dump of the heat-power plant, made it possible to reveal certain peculiarities of heavy metals accumulation in the above-ground part of knotweed.
