This study investigated the impact of local anthropogenic activity on the marine environment around the remote harbor of Qeqertarsuaq, West Greenland. Blue mussels (Mytilus sp.) were used as a bioindicator, and their physiological condition was found to decrease with increasing proximity to the harbor. Subsequently, the distribution of 19 polycyclic aromatic hydrocarbons (PAHs) and 9 groups of alkylated PAHs were measured in mussel and sediment samples. The highest values were found in a rocky collection area 15 m from a wooden pier frequented by small boats. A PAH source investigation, indicated a mixed source from light fuel oils and creosote used as boat coating. Finally, correlations between the mussels morphological condition and the PAH pollution were found to be significant for 4-, 5-, and 6-ring PAHs. In conclusion, the results indicate that pollution sources in harbors have significant effects on the local environment and should be considered in arctic conservation research.

本研究调查了当地人为活动对西格陵兰岛 Qeqertarsuaq 偏远港口周围海洋环境的影响。蓝贻贝（Mytilussp.) 被用作生物指标，并且发现它们的生理状况随着距离港口的增加而降低。随后，测量了贻贝和沉积物样品中 19 种多环芳烃 (PAH) 和 9 组烷基化 PAH 的分布。在距离小船经常光顾的木码头 15 m 的岩石收集区中发现了最高值。PAH 来源调查表明，轻质燃料油和杂酚油的混合来源用作船用涂层。最后，发现贻贝形态条件与 PAH 污染之间的相关性对于 4、5 和 6 环多环芳烃是显着的。总之，结果表明港口污染源对当地环境有显着影响，应在北极保护研究中予以考虑。
