This study evaluates the use of the sandhopper Talitrus saltator as a bioindicator of PAHs contamination of the supralittoral zone of sandy beaches. Adult amphipods were collected at eight localities on the Tuscany shore in summer. Concentrations of 16 PAHs indicated as priority pollutants by the Environmental Protection Agency were determined. T. saltator is able to accumulate PAHs (total PAHs ranging from 0.75 to 62.1 ng g(-1)), with concentrations generally greater than in the sand (total PAHs ranging from 0.04 to 38 ng g(-1)). In particular, it accumulates Phe, Cry, and BbF. Preliminary laboratory tests indicate food as a possible route of PAHs intake by sandhoppers. Despite the need of further studies to clarify the variability of the PAH concentrations found in the substrata and in sandhoppers, T. saltator could be used as a bioindicator of PAHs contamination of the supralittoral zone of sandy shores.
本研究评估了沙蚤 Talitrus saltator 在作为沙质海滩潮上带多环芳烃污染生物指示剂方面的应用。在夏季，于托斯卡纳海岸的八个地点采集成年十足目动物。测定了被环境保护署列为优先污染物的 16 种多环芳烃的浓度。T. saltator 能够积累多环芳烃（总多环芳烃范围为 0.75 至 62.1ng g(-1)），浓度通常高于沙中（总多环芳烃范围为 0.04 至 38ng g(-1)）。特别是，它积累了 Phe、Cry 和 BbF。初步实验室测试表明，食物可能是沙蚤摄入多环芳烃的途径之一。尽管需要进一步的研究来澄清在基质和沙蚤中发现的多环芳烃浓度的可变性，但 T. saltator 可以用作沙质海岸潮上带多环芳烃污染的生物指示剂。
