An almost ubiquitous occurrence of imposex and butyltins in the molluscs from US Virgin Islands gives evidence to a widespread contamination with the antifouling agent tributyltin (TBT), which most likely is related to a relatively intense ship traffic. Three different muricid neogastropod species Thais deltoidea, Thais rustica and Purpura patula all seem to have potential as suitable and sensitive bioindicators for assessing levels and effects of TBT pollution in coastal areas including coral reefs in the Caribbean Sea. However, considerable interspecies differences in especially accumulation potential of butyltins were seen in this study. Furthermore, a high accumulation potential of TBT in the edible gastropod West Indian topshell (Cittarium pica) was found, despite that no signs of imposex were observed in this archaeogastropod species.
美属维尔京群岛软体动物中几乎普遍存在性畸变和丁基锡，这证明了防污剂三丁基锡（TBT）的广泛污染，这很可能与相对密集的船舶交通有关。三种不同的骨螺科新腹足类物种，即三角荔枝螺、疣荔枝螺和紫螺，似乎都有潜力作为合适且敏感的生物指标，用于评估包括加勒比海珊瑚礁在内的沿海地区TBT污染的水平和影响。然而，在本研究中观察到，特别是丁基锡的积累潜力存在相当大的种间差异。此外，尽管在这种原始腹足类物种中未观察到性畸变迹象，但在可食用的腹足类动物西印度帽贝（Cittarium pica）中发现了TBT的高积累潜力。
