Heavy metals in sediments and waters in the Chukchi Plateau and adjacent waters were investigated in this study. The results showed that most metals (especially Ni, As and Co) have accumulated in sediments, and their levels followed the order of Zn > Ni > Co > Cr > Cu > As > Pb > Cd. Spatial variations of environmental variables and metal characteristics were revealed based on the transect research. Furthermore, heavy metal concentrations presented vertical variations in water column with the levels of Ni > As > Zn > Cu > Cr > Pb > Cd > Co, and they were inhomogeneous in different water masses. This paper will be helpful to the study of the pollution and distribution of the heavy metals in Arctic Ocean and its surrounding environment.
