Abstract

The distribution of different homological groups of polychlorinated biphenyls (PCBs) in the urbanozem profile of the arboretum in the Botanical Garden of Moscow State University has been considered. The levels of their content, the composition of a congener spectrum, potential sources, and the ecotoxicological impact of soil pollution are assessed. The maximal concentrations of di-, tri-, and tetrachlorbiphenyls are observed in the technogenic layer of soil at a depth of 20–40 cm (0.30, 0.44, and 24.25 μg/kg, respectively), and penta- and hexachlorbiphenyls in the surface humus layer (42.33 and 17.89 μg/kg, respectively). The content of hepta- and oñtachlorbiphenyls varies insignificantly with increasing the depth (0.67–1.25 and 0.15–0.41 μg/kg, respectively). Penta- and hexachlorbiphenyls contribute most to the spectrum of PCBs in urbanozem.
