Abstract
In the review information about the main organochlorine pesticides (OCPs), which were widely used in world agriculture in 1940-60 and continue to be used in some developing countries, are presented. The patterns of their distribution in the environment, toxicity, metabolism and degradation are described. The distribution in ecosystem components of different regions of the World Ocean and, specifically, in the Far Eastern seas of Russia (the Sea of Japan, the Sea of Okhotsk and the Bering Sea) in the period 2000-2016 is shown. In the Sea of Okhotsk and the Bering Sea, the content of OCPs in marine organisms is lower than in other regions of the world ocean, and, in particular, in the Sea of Japan. The results show that a background of pesticides has formed on the planet. OCP concentrations in the Sea of Okhotsk and the Bering Sea can be considered background, while the Sea of Japan is affected by countries using these substances in agriculture.
