Heavy Metal Content in the Seagrass <i>Zostera marina</i> Linnaeus, 1753 in Voevoda Bay (Amur Bay, Sea of Japan)

Abstract

Concentrations of heavy metals in live and dead leaves, stems, rhizomes and roots of the seagrass Zostera marina Linnaeus, 1753 were analyzed in the study. On the basis of concentration, the metals were arranged in the following row: Fe Mn Zn Cu Pb Ni Cd. Differences in Fe, Pb, Ni, and Cd for live and dead leaves were revealed. The factor of sediment enrichment in heavy metals from dead leaves was calculated. The enrichment factor for the metals under study changed in the row Cu Pb Zn Ni Mn, and the value of solubility product [–lg(SP)] for sulfides of the above-listed metals changed in the same row.
