Accumulation of Polycyclic Aromatic Hydrocarbons Betula nana under the Conditions of Technogenesis
https://doi.org/10.18412/1816-0395-2019-1-32-37
Abstract
The content of polycyclic aromatic hydrocarbons (PAHs) in Betula nana L. was studied in the background area and at different distances from the coal mining enterprise. A close correlation was found between the content of polyarenes in coal, snow cover and plants. It was established that the content of PAHs in plants in polluted areas exceeds background values by 2 times and slightly decreases with distance from the mine. The largest multiples of exceedances are noted for heavy polyarenes. The contribution of surface contamination to the total PAH content in the plant was about 20 %. The distribution of PAHs in the organs of Betula nаna is uneven: light PAHs actively penetrated the leaves and branches of Betula nаna in the range of up to 1 km from the mine; In the stems of birch PAH penetrated in small quantities. Betula nana can be used as an indicator species characterizing the degree of pollution of the territory of the PAH coal industry enterprises. When assessing short-term contamination, plant leaves can be used, for analysis of long-term exposure – the bark of Betula nana.
