Mercury (Hg) is an important environmental indicator of anthropogenic pollution. In this study, the Hg content in the bottom sediments of the East Siberian Sea was observed to range from 13 to 92 ppb, with an average of 36 ppb. Facies dependence was also observed and expressed as an increase in the Hg concentration in fine-sized sediments on the shelf edge and continental slope, compared to that in the sandy silts and sands of the inner shelf. The Hg accumulation in bottom sediments of the eastern part has increased over the past 150 years due to an increase in global emissions of anthropogenic Hg, which is caused by the transboundary transport of Hg to the Arctic. Moreover, changes in the Hg value, which occur due to the plankton arriving at the bottom sediments because of changes in hydrology and primary production, are thought to be associated with global warming.

汞（Hg）是人为污染的重要环境指标。在这项研究中，观察到东西伯利亚海底沉积物中的汞含量为13到92 ppb，平均为36 ppb。还观察到相依存性，并表示为与内层架的沙质粉砂和沙层相比，层架边缘和大陆坡上的细颗粒沉积物中的汞浓度增加。在过去的150年中，由于人为汞的全球排放增加，这是由于汞跨界运输到北极所致，东部底部沉积物中的Hg积累有所增加。此外，由于水文学和初级生产的变化，浮游生物到达底部沉积物而引起的汞值变化，
