以前关于海洋生物对纳米塑料的吸收和影响的研究是在可能不切实际的高浓度下进行的。这是在环境相关浓度下跟踪生物体中塑料颗粒的分析挑战的结果，并突出了对新方法的需求。在这里，我们将碳-14放射性标记的纳米聚苯乙烯脉冲暴露于一种商业上重要的软体动物，Pecten maximus，预计其浓度与环境有关(
Previous studies of uptake and effects of nanoplastics by marine organisms have been conducted at what may be unrealistically high concentrations. This is a consequence of the analytical challenges in tracking plastic particles in organisms at environmentally relevant concentrations and highlights the need for new approaches. Here, we present pulse exposures of C-14-radiolabeled nanopolystyrene to a commercially important mollusk, Pecten maximus, at what have been predicted to be environmentally relevant concentrations (
