Temporal patterns, fluxes and inventories of polychlorinated biphenyls (PCBs) were assessed in nine sediment cores collected from selected areas of Admiralty Bay off the Antarctic Peninsula. Concentrations of total PCBs were low, but slightly higher in comparison to low-impacted, remote environments in the world, ranging from below the detection limit to 11.9ngg in dry weight. PCB concentrations and inventories suggest a possible minor influence related to the nearby logistic activities, especially in the sediment core collected close to the Ferraz Station. Despite being the most remote and protected area on the planet, the Antarctic continent is no longer a pristine environment.
本研究评估了从南极半岛附近的 Admiralty 湾选定区域采集的 9 个沉积物岩心中的多氯联苯（PCBs）的时间模式、通量和存量。总 PCB 浓度较低，但略高于世界上受影响较小的偏远地区，范围从检测限以下到干重 11.9ngg。PCB 浓度和存量表明，附近物流活动可能有一定的轻微影响，特别是在靠近费拉兹站采集的沉积物岩心中。尽管南极洲是地球上最偏远和受保护的地区，但它已不再是原始环境。
