The impact of Sumy TPP on the environment of surrounding area

Abstract

The purpose of the work is to determine the influence of thermal power plant on atmospheric air and soil and the study of heavy metals migration in environmental components.The estimation of the influence of Sumy TPP on the environment condition of the surrounding territories of Sumy during the income of pollutants with gas emissions and filtration from the zone of aeration and ash and slug dump is presented. For studies of the impact of the TPP on the adjacent territory was organized a network of observation points in the zone of influence the Sumy TPP. The assessment of atmospheric air pollution was carried out by studying the snow cover. Complex estimation of the pollution of adjacent territories to the thermal power plant was carried out using the total pollution indexSamples of snow cover, soil and vegetation were sampled, and tested for the content of heavy metals. An assessment was made of the pollution of snow cover and soils by the total pollution index and for the grass pollution by the coefficient of biogeochemical activity. Studies have shown that the level of snow cover pollution in the aeration zone of Sumy TPP is low. The level of soil contamination in the aeration zone of Sumy TPP is low, and the soils in the ash and slug dump zone: for the upper horizon are high, for the lower - medium, indicating the complex impact of atmospheric air pollution and the migration of substances from the body of the ash dip. The study of the most common types of grass Taracxacum officinale and Elytrigia repens showed the ways of migration of heavy metals and allowed to recommend these plants for bioindication of soil contamination by heavy metals. The assessment of the pollution of territories adjacent to the thermal power plant showed that the activity of Sumy TPP leads to increasing of heavy metals concentrations in environment.
