Microplastics and nanoplastics are emerging pollutants of concern in the aquatic environment that are causing increasing global environmental and human health problems. Although there has been extensive research on microplastics and nanoplastics, little has been said about the differences in their behavior in the aquatic environment, and many studies have considered them as the same class of hazardous materials; but in fact, microplastics and nanoplastics should be considered as two different types of environmentally hazardous materials. In this review, we propose that microplastics and nanoplastics behave in the aquatic environment in a size-dependent manner and should be distinguished. And we systematically analyzed the differences in the behavior of microplastics and nanoplastics in the aquatic environment in terms of five aspects: 1) distribution behavior; 2) adsorption behavior; 3) reaction with natural colloids; 4) aging and leaching behavior; 5) interaction with organisms. This paper has been written to draw academic attention to the different behaviors of microplastics and nanoplastics in the aquatic environment in order to distinguish between their effects on humans and the environment.
微塑料和纳米塑料是水生环境中日益引起关注的新兴污染物，正给全球环境和人类健康带来越来越多的问题。尽管对微塑料和纳米塑料已有广泛研究，但关于它们在水生环境中行为的差异却鲜有提及，许多研究将它们视为同一类有害物质；但实际上，微塑料和纳米塑料应被视为两种不同类型的环境有害物质。在本综述中，我们提出微塑料和纳米塑料在水生环境中的行为具有尺寸依赖性，应加以区分。并且我们从五个方面系统分析了微塑料和纳米塑料在水生环境中行为的差异：1）分布行为；2）吸附行为；3）与天然胶体的反应；4）老化和浸出行为；5）与生物体的相互作用。撰写本文旨在引起学术界对微塑料和纳米塑料在水生环境中不同行为的关注，以便区分它们对人类和环境的影响。
