| Popis: | Power facilities significantly affect the environment. Moreover, this effect is characterized by constant and growing intensity, variety, diversity and scale. Therefore, the purpose of the research is to study the impact of Dobrotvir thermal power plant on the accumulation and migration of heavy metals (HM) in soils of surrounding areas. The results of our studies found increased content concealed in the soil samples taken at a distance of 1.5‑2.5 km from Dobrotvir thermal power plant (DTPP). The authors have revealed the tendency to reduction of the HM at some distant areas of DTPP. The accumulation of such heavy metals as nickel compounds, lead, and zinc was found on all distant monitoringplots. The research has also defined interdependence and correlation between the contents of the HM and pH soils, and some agrochemical indicators of studied soils. The authors have found a significant excess in the soil samples when studying the contents of the HM as of lead, copper, iron, manganese and nickel in comparison with the control point. Moreover, we have detected some decrease of humus content in the soil and increasing the pH to sodpodzolic soil. Thus, the authors recommend source control of polluting emissions and comply with relevant environmental legislation. The greatest negative impact on the environment is caused by thermal power plants. This is mainly due to the environmental aspects of fossil fuels. The coal ash is a kind of concentrate compounds of several elements. It has long been important to ore and therefore dust falling from year to year on the same territory, sooner or later, will increase the content of toxic heavy elements in the components of the environment far beyond the safe mark. |
