Abstract

The paper presents the results of the study of the content of polychlorinated biphenyls in soil and sediment samples taken from the high-power transformer station in the city of Ciadâr-Lunga, as well as the impact of these contaminants on different organisms. Chromatographic analysis established the presence of polychlorinated biphenyls in all analyzed samples, ΣBPC ranging from 143.6 mg/kg to 1671.3 mg/kg. Polychlorinated biphenyls showed various side effects on the tested organisms: from unobservable (species Eisenia fetida and Helix pomatia) to lethal (species: Daphnia magna and Phyllobius urticae).
