Ebook: Heavy metal contents in the pink salmon Oncorhynchus gorbuscha Walbaum, 1792 from Kuril oceanic waters during anadromous migration

Статья. Опубликована в Russian Journal of Marine Biology — 2015. — Т. 41. — №6. — С. 479–484. — DOI 10.1134/S1063074015060085.The contents of trace elements, viz., Hg, As, Pb, Cd, Zn, and Cu, in a common species of Pacific salmon, viz., the pink salmon, which were caught in early July 2012 and 2013 in the vicinity of Kuril Islands, were examined. It was found that the contents of toxic elements, Cd, Pb, As, and Hg, in the salmon meet human health consumption guidelines for seafood by the sanitary standards and regulations of the Russian Federation. The contents of all of the metals (except zinc) in pink salmon from the geochemically extreme Kuril area were higher than that in pink salmon from the Sea of Japan. The greatest difference was recorded for lead, whose concentrations in organs and tissues (liver, gonads, and muscle) of fish from Kuril oceanic waters was one and a half order of magnitude higher than that of pink salmon from the Sea of Japan.
