Organic contamination in freshwater samples has never been investigated at the western shore of Admiralty Bay. Therefore, the presence of polycyclic aromatic hydrocarbons (PAHs) in five different sites distributed along a shore running from the Arctowski Station to the Baranowski Glacier was studied. Moreover, organic compounds such as n-alkanes, toluene and ethylbenzene were also noted. Increased ΣPAHs in late Austral summer 2016 are the result of long-range atmospheric transport of air masses from South America, confirmed by 10-day backward air mass trajectories analysis. The presence of n-alkanes and other hydrocarbons, as well as the evaluation of PAH indices (e.g. ΣLMW/ΣHMW* > 1), shows the use of fuel and indicate local human activity. As a final conclusion, our analysis indicates a mixed origin of PAHs (global and local). The presence of PAHs and other hydrocarbons in the water environment may constitute a potentially negative effect on the Antarctic ecosystem and it should be investigated in detail during further research (//*ΣLMW-sum of low molecular weight PAHs (two- and three-ring PAHs); ΣHMW-sum of high molecular weight PAHs (four- and five-ring PAHs)//).

在阿德默勒尔蒂湾的西岸，从未对淡水样本中的有机污染物进行过调查。因此，研究了分布在从阿图什站到巴拉诺夫斯基冰川的一条海岸的五个不同地点的多环芳烃 (PAHs) 的存在情况。此外，还注意到了正构烷烃、甲苯和乙苯等有机化合物。2016 年晚秋 ΣPAHs 的增加是由来自南美洲的长距离大气传输的空气团造成的，这一点通过 10 天的向后气团轨迹分析得到了证实。正构烷烃和其他碳氢化合物的存在，以及 PAH 指数的评估（例如 ΣLMW/ΣHMW* > 1），表明使用了燃料并指示了当地的人类活动。作为最终结论，我们的分析表明 PAHs 具有混合来源（全球性和局部性）。PAHs 和其他碳氢化合物在水环境中的存在可能对南极生态系统构成潜在的负面影响，在进一步的研究中应详细调查（//*ΣLMW-低分子量 PAHs（二和三环 PAHs）的总和；ΣHMW-高分子量 PAHs（四和五环 PAHs）的总和//）。图表摘要。
