The use of sandhoppers and beachfleas as biomonitors of heavy metals contamination is relatively recent. Using adult individuals of Talitrus saltator from nine localities on the northern Mediterranean Sea, we studied the concentrations of eight trace elements: Al, Cd, Cr, Fe, Hg, Pb, Cu, Zn, both in the substratum and in the individuals. We also carried out a preliminary investigation of the correspondence between the sandhoppers' genetic variability and heavy metal contamination at the sampling sites. T. saltator accumulated Cd, Cu, Zn and Hg (at higher concentrations than in the sand) and also Al and Fe (at lower concentrations than in the sand). It seems that Mediterranean sandhoppers do not accumulate Pb and Cr. An intraspecific comparison between northern European (Baltic) and Mediterranean populations of T. saltator was made. Finally, we observed a tendency to a positive correlation between the sandhoppers' genetic variability and heavy metals contamination.
使用沙蚤和滩蚤作为重金属污染的生物监测手段相对较新。我们利用来自地中海北部九个地点的成年跳钩虾（Talitrus saltator）个体，研究了基质和个体中八种微量元素（铝、镉、铬、铁、汞、铅、铜、锌）的浓度。我们还对采样地点沙蚤的遗传变异性与重金属污染之间的对应关系进行了初步调查。跳钩虾积累了镉、铜、锌和汞（浓度高于沙中），也积累了铝和铁（浓度低于沙中）。地中海沙蚤似乎不会积累铅和铬。我们对北欧（波罗的海）和地中海地区的跳钩虾种群进行了种内比较。最后，我们观察到沙蚤的遗传变异性与重金属污染之间存在正相关的趋势。
