Biogeochemical Controls on PCB Accumulation in the East Siberian Arctic Shelf
Original language description
Climate change-induced increases in sea ice retreat and coastal erosion affect polar biogeochemical processes of persistent organic pollutants. This study investigated the distribution and fate of traditional and emerging Polychlorinated biphenyls (PCBs) in the sediments of the East Siberian Sea (ESS) and Chukchi Sea (CS). PCB 11 was the most dominant PCB congener detected in the sediments. PCB concentrations were higher in the open sea of the CS and along the ESS shelf break than in the ESS coastal region. Based on the correlation between PCB concentrations and total organic carbon (OC), as well as the result of the Positive Matrix Factorization model, the release of historical PCBs from eroded soils along the Siberian coast dominated in the ESS coastal region, whereas biogenic deposition of emerging PCBs prevailed in open sea areas. These findings highlight that the spatial heterogeneity of OC with varied origins determines the fates of PCBs in the high-latitude marginal seas.
