In the present study, we examine contamination with PCBs, HCB and PAHs in the seawater of Arctic fjords (Hornsund, Kongsfjorden and Adventfjorden) which differ in environmental conditions and are particularly sensitive to climate change. We also investigate how the melting glaciers and ocean currents may affect the distribution and fate of target compounds in the seawater column in the fjords. The ∑7 PCB, HCB and ∑12 PAH concentrations in seawater ranged from, respectively: 0.002 to 41.2 ng/L; from LOQ to 233 ng/L; and from 0.196 to 311 ng/L. The research indicates that the concentrations of contaminants detected in Arctic fjords depend on the physicochemical properties of these compounds, local human activity and occurrence of glacier meltwaters. Detected HCB and PAH concentrations in most of the seawater samples were at levels classified as harmless, however in 30 out of 80 analysed suspended particulate matter samples some compounds were present at toxic levels.

在本研究中，我们研究了北极峡湾（Hornsund，Kongsfjorden和Adventfjorden）海水中多氯联苯，六氯代苯和多环芳烃的污染，这些污染物的环境条件各异，并且对气候变化特别敏感。我们还研究了冰川融化和洋流如何影响峡湾海水柱中目标化合物的分布和命运。海水中Σ7PCB，HCB和Σ12PAH的浓度分别为0.002至41.2 ng / L；LOQ至233 ng / L 从0.196到311 ng / L。研究表明，在北极峡湾中检测到的污染物浓度取决于这些化合物的理化特性，人类的局部活动以及冰川融水的发生。
