New data on the occurrence of POPs, including polychlorinated biphenyls (PCBs) and legacy pesticides (LPs), along with current-use pesticides (CUPs) in the surface marine sediments of Kongsfjorden over five years (2018–2022) are presented. LPs examined were p,p’-dichlorodiphenyltrichloroethane (DDT), p,p’-l,l-dichloro-2,2-bis(chlorophenyl)ethylene (DDE), and hexachlorocyclohexane (HCH), while CUPs included chlorpyrifos (CPF), dacthal (DAC), and endosulfan (ENDO). LPs (0.12–0.59 ng/g) were in higher amounts than CUPs (0.01–0.15 ng/g). The first data on CPF (0.003–0.07 ng/g) and DAC (0.001–0.06 ng/g) in Arctic marine sediments were obtained. Σ34PCBs (0.25–0.62 ng/g) were found with a dominance of lower molecular weight congeners, probably transported via atmospheric currents.

斯瓦尔巴群岛 Kongsfjorden 北极峡湾海洋沉积物中的持久性有机污染物 (POP)
介绍了五年(2018-2022 年)Kongsfjorden 表层海洋沉积物中持久性有机污染物(包括多氯联苯 (PCB) 和传统杀虫剂 (LP)以及当前使用的杀虫剂 (CUP) 出现的新数据。检查的 LP 是对,对'-二氯二苯基三氯乙烷 (DDT)、对对'-l,l-二氯-2,2-双(氯苯基)乙烯 (DDE) 和六氯环己烷 (HCH),而 CUP 包括毒死蜱 (CPF)、指片 (DAC) 和硫丹 (ENDO)。LP (0.12–0.59 ng/g) 的含量高于 CUP (0.01–0.15 ng/g)。获得了北极海洋沉积物中 CPF (0.003-0.07 ng/g) 和 DAC (0.001-0.06 ng/g) 的第一个数据。发现 Σ34PCBs (0.25–0.62 ng/g) 以较低分子量同系物为主,可能通过大气流传输。
