Abstract
The levels of six chemical elements (mercury, arsenic, lead, cadmium, zinc and copper) were examined in two species of Pacific salmon, genus Oncorhynchus, pink salmon (Oncorhynchus gorbuscha), and chum salmon (Oncorhynchus keta) that were caught in the Kuril waters in July 2013. Concentrations of toxic elements (Hg, As, Pb, Cd) in both species were shown to be below the maximum concentration limits of these trace elements for seafood. The concentrations of these elements were compared between wild salmons and hatchery-grown salmons of the Pacific and Atlantic oceans.
