Ficopomatus enigmaticus was adopted as model species for ecotoxicological bioassay, with its larval development as endpoint. Two different populations of the same species, collected in areas far from each other (Mediterranean Sea and Atlantic Ocean), were exposed to multi-walled carbon nanotubes, a class of emerging pollutants with a constantly increasing relevance in the landscape of nanomaterials production. Moreover, a molecular analysis based on Cyt b amplification and sequencing, was carried out to confirm that both populations belong to the same species. The aim of the present work was to strengthen existing results about F. enigmaticus relevance in ecotoxicological bioassays, adding the variable of population effect. For both populations the concentration-response curve of effect at different toxicant concentrations was similar and, at certain concentrations, overlapping, confirming the ecological relevance of the assay. These results posed an interesting acceptance on the introduction of this species as model in ecotoxicological bioassay scenery, underlining the relevance of a widespread wild species to compare effects of chemicals and environmental samples over large distances using the same bioassay.

Ficopomatus enigmaticus被用作生态毒理生物测定的模型物种，其幼体发育为终点。在彼此相距遥远的地区（地中海和大西洋）收集的两个相同物种的不同种群，暴露于多壁碳纳米管，这是一类新兴污染物，在纳米材料生产领域中的重要性与日俱增。此外，进行了基于Cyt b扩增和测序的分子分析，以确认两个种群属于同一物种。当前工作的目的是加强关于F. enigmaticus的现有结果与生态毒理生物测定的相关性，增加了种群效应的变量。对于这两个人群，在不同毒物浓度下的浓度-效应曲线相似，并且在某些浓度下重叠，从而证实了该测定法的生态相关性。这些结果引起了人们对该物种作为生态毒理学生物测定景观模型的兴趣，这突显了一种广泛的野生物种对于使用同一生物测定法在远距离比较化学药品和环境样品的影响的相关性。
