Heavy metal concentrations in deep-sea sediments collected from Kuril Basin (Sea of Okhotsk) and Kuril-Kamchatka Trench area were analyzed. For the Kuril Basin, a geochemical natural background of these elements was identified based on a dated core. The results showed enrichment by heavy metals due to natural factors in the study area. All heavy metals showed a low ecological risk; thus, the potential ecological risk of the study area was also low.
