Content of the metals Fe, Mn, Ni, Pb, Zn, Cd, and Cu was determined in the water, suspended matter, plankton organisms and bivalves collected in the brackish-water lagoon lakes on the coast of the Japan Sea in July 2011-2012, August 2013, and July 2014. The lakes are located in the sparsely populated area of eastern Sikhote-Alin including the Sikhote-Alin biosphere nature reserve. The content of Fe, Mn, Ni, and Pb has a tendency to decrease along the trophic chain that is conditioned by prevalence of their suspended forms over dissolved ones in the water and decreasing of the surface : weight ratio with size of living organisms. On the contrary, the content of Cu, Zn and Cd is rather stable along the food chain because of prevalence of their dissolved forms and low content in the suspended organic matter.
