这篇综述讨论了纳米塑料（NP）和工程纳米粒子（ENP）在多孔介质中的研究现状、缺点和前景，以及ENP的可借用部分。首先，最重要的部分是我们回顾了纳米粒子在多孔介质中的命运和主要影响因素的研究现状，并解释了影响机制。其次，为了给NPs的研究思路和影响机制提供参考，我们还回顾了ENPs在多孔介质中的命运以及影响其命运的因素和机制的研究现状。总结了影响ENPs运输的主要机制（保留或运输模式：平流、扩散、分散、沉积、吸附、阻塞、成熟和应变；主要力和作用：布朗运动、重力、静电力、范德华力、水合、过滤、桥接；影响力和作用的因素：ENP和介质颗粒表面官能团、尺寸、形状、zeta电位、密度、疏水性和粗糙度）。由于 NP 和 ENP 差异很大，因此需要对 NP 进行深入研究，而不是使用 ENP 的研究结果。基于现有关于多孔介质中纳米粒子输运的有限研究，我们发现虽然ENPs的结论不能适用于NPs，但ENPs总结的大多数影响机制适用于NPs。结合ENPs的研究思路、NPs的研究现状以及我们的一些经验和反思，我们回顾了目前多孔介质中NPs命运研究的不足以及对未来研究的展望。该综述对于阐明多孔介质中纳米粒子命运的研究现状和影响机制非常有意义，也为未来多孔介质中纳米粒子命运的研究方向提供了很大的启发。

Statuses, shortcomings, and outlooks in studying the fate of nanoplastics and engineered nanoparticles in porous media respectively and borrowable sections from engineered nanoparticles for nanoplastics

This review discussed the research statuses, shortcomings, and outlooks for the fate of nanoplastics (NPs) and engineered nanoparticles (ENPs) in porous media and borrowable sections from ENPs for NPs. Firstly, the most important section was that we reviewed the research statuses on the fate of NPs in porous media and the main influencing factors, and explained the influencing mechanisms. Secondly, in order to give NPs a reference of research ideas and influence mechanisms, we also reviewed the research statuses on the fate of ENPs in porous media and the factors and mechanisms influencing the fate. The main mechanisms affecting the transport of ENPs were summarized (Retention or transport modes: advection, diffusion, dispersion, deposition, adsorption, blocking, ripening, and straining; Main forces and actions: Brownian motion, gravity, electrostatic forces, van der Waals forces, hydration, filtration, bridging; Affecting elements of the forces and actions: the ENP and media grain surface functional groups, size, shape, zeta potential, density, hydrophobicity, and roughness). Instead of using the findings of ENPs, thorough study on NPs was required because NPs and ENPs differed greatly. Based on the limited existing studies on the NP transport in porous media, we found that although the conclusions of ENPs could not be applied to NPs, most of the influencing mechanisms summarized from ENPs were applicable to NPs. Combining the research thoughts of ENPs, the research statuses of NPs, and some of our experiences and reflections, we reviewed the shortcomings of the current studies on the NP fate in porous media as well as the outlooks of future research. This review is very meaningful for clarifying the research statuses and influence mechanisms for the NP fate in porous media, as well as providing a great deal of inspiration for future research directions about the NP fate in porous media.
