Scientists of the FEFU study the Far Eastern seas for pollution by toxins

A comprehensive study of the degree of pollution of the Far East seas by toxic substances is planned by FEFU scientists, the university press service reported. Experts plan to determine the concentrations of traditional and identify new toxins.

It is reported that studies will assess the risks from local seafood for the health of residents of the coastal regions of the Far Eastern region, including indigenous small peoples of the North. It is also planned to supplement the data on levels of pollutants in the World Ocean, to determine the environmental risk for marine organisms. "The concentration of organochlorine pesticides (CVD) in marine organisms, especially in fish, is especially dangerous, as these seafood are actively used by people. The accumulated effect of CVD and polychlorinated biphenyls (PCBs) is manifested in the form of a mutagenic effect, both in adults and in mother-to-child transmission in utero and when fed. The peculiarity of these substances is that they are contained in low concentration, but have high toxicity. Therefore, their study and monitoring is so important, "the words of Project Manager Olga Lukyanova are quoted in the message.

Earlier, FEFU scientists discovered pesticides in organisms of large marine inhabitants of the North Pacific and found that these harmful substances accumulate in organisms with a high fat content. HOP and PCBs enter the ocean as a result of human activities, present a particular danger.
