Polycyclic Aromatic Hydrocarbons in Betula nаnа (Betulaceae, Magnoliópsida) under the Impact of a Thermal Power Plant

The content of polycyclic aromatic hydrocarbons (PAH) in Betula nаnа L. and soil organogenic horizons was studied at a control site and sites affected by a thermal power station (TPS) at distances of 0.5, 1.0, and 1.5 km from the source of pollution. The PAH distribution over the vegetative organs of dwarf birch was irregular. The qualitative composition of PAH in different organs of dwarf birch was similar. No significant changes in the PAH content in dwarf birch organs and at the surface of these organs at different distances from the TPS were revealed.
