Evaluation of Pollution Level in Zolotoy Rog Bay (Peter the Great Gulf, the Sea of Japan)

[摘要] The results of the hydrochemical research of water and bottom sediments of the Zolotoy Rog Bay in July 2015 are presented below. It is shown that, as a result of a large amount of polluted sewage entering The Zolotoy Rog Bay, the concentrations of organic substances (BOD5) and petroleum hydrocarbons in the water exceed the MPC. The concentrations of heavy metals in soils exceed both the background level and the level of permissible values. As a result of the calculation of the bottom accumulation (CBA) coefficient for oil hydrocarbons, the situation in the Zolotoy Rog Bay can be classified as an ecological disaster. According to the total pollution index (Zc) of heavy metals, the bottom sediments of the Zolotoy Rog Bay are characterized as strongly and very strongly polluted.
