Imposex was found in the Arctic whelk Buccinum finmarkianum at several marine stations off Thule Air Base, an US military facility in Northwest Greenland. This indicates a widespread contamination with the antifouling agents, tributyltin (TBT) or triphenyltin (TPhT) in the area, but such contamination was not supported by the organotin analyses in sediments, whelks and clams, which in general was below the analytical detection limit. Organotin concentrations above the detection limit were found only at one station close to a quay, where the highest frequency of imposex also occurred. This suggests that imposex in B. finmarkianum is a biomarker of TBT more sensitive than the detection limits, which the analytical chemistry could achieve in this study.
在位于格陵兰岛西北部的美国军事设施图勒空军基地附近的几个海洋监测站中,人们在北极蛾螺(Buccinum finmarkianum)体内发现了性畸变现象。这表明该区域受到了防污剂三丁基锡(TBT)或三苯基锡(TPhT)的广泛污染,但沉积物、蛾螺和蛤蜊中的有机锡分析结果却不支持这一点,总体而言这些分析结果低于分析检测限。仅在靠近一个码头的一个监测站发现了高于检测限的有机锡浓度,而该监测站也是性畸变发生率最高的地方。这表明,北极蛾螺体内的性畸变是三丁基锡的一种生物标志物,其比本研究中分析化学所能达到的检测限更为敏感。
