| Abstract: | The results of the comparative analysis of data of annual observations conducted in the framework of the program for the state monitoring of hydrochemical conditions and pollution of coastal sea waters in the Primorsky krai, Sakhalin, and Kamchatka are presented. Among the numerous pollutants coming to the marine environment, the priority ingredients for these water areas were selected. They characterize the marine environmental conditions in terms of the frequency of high concentrations exceeding the maximum permissible concentration (MPC) and in terms of toxicity: oil hydrocarbons, phenols, synthetic surfactants, and heavy metals. Specific features of interannual dynamics of average annual and maximum concentrations of pollutants for the certain periods are considered as well as the main trends in the composition and quality of water resulting from the anthropogenic impact in 1975–2015. |
