对环境中制造的纳米颗粒（NP）的研究几乎完全在高NP浓度下进行。这些数据导致了对NP在相关环境浓度下的归宿和影响的误解，预计这些浓度很低。更好地了解浓度依赖行为的纳米颗粒将提高我们的理解，他们的命运和环境现实conditions.Abstract的影响，这种快速的通信突出了纳米颗粒浓度的重要性，在确定其环境命运和行为。值得注意的是，已经考虑了两个归宿过程：溶解和聚集。纳米颗粒浓度的降低导致溶解增加和聚集体尺寸减小，推断纳米颗粒的环境运输的更高潜力。
Environmental context Studies of manufactured nanoparticles (NPs) in the environment have been performed almost exclusively at high NP concentrations. These data lead to misunderstandings related to NP fate and effects at relevant environmental concentrations, which are expected to be low. A better understanding of the concentration-dependent behaviour of NPs will improve our understanding of their fate and effects under environmentally realistic conditions.Abstract This rapid communication highlights the importance of nanoparticle concentration in determining their environmental fate and behaviour. Notably, two fate processes have been considered: dissolution and aggregation. The decrease in nanoparticle concentration results in increased dissolution and decreased aggregate sizes, inferring higher potential for environmental transport of nanoparticles.
