Main factors in polycyclic aromatic hydrocarbons accumulations in the long-term technogenic contaminated soil

The PAHs transformation in the soils of coal mining enterprises impact zones and thermal power plants remains poorly studied. In turn, can be considered as a primary cycle production electricity. One main sources negative environmental is industry located on territory upland south East European Plain. features accumulation fuel energy have been studied example mines with different service life current coal-fired plant. It was established that, regardless period intensity emission source, well its status, polycyclic aromatic hydrocarbons (PAHs) content significantly higher than background territory. low molecular high weight differed depending land use type, an industrial effect type. pollutants all exceeded values according to soils, they formed following decreasing series: Mayskiy ≥ Ayutinsky > Novoshahtinsk Power station Background. According content, series changed to: >Mayskiy Soil pollution markers for complex were identified pyrene chrysene, which are part coal, from hydrocarbon sources. influence plant accompanied by benzo(g,h,i)perylene concentration increase.
