摘要

微塑料(MP)和纳米塑料(NP)在城市水域中普遍存在且难以处理。与MPs相比,较小的NP表现出明显的物理化学特征,如布朗运动、较高的比表面积以及与其他污染物更强的相互作用。因此,NP的定性和定量分析比MP更具挑战性。此外,这些特征赋予了NP与城市水域中MP显著不同的环境命运、与污染物的相互作用以及生态影响。在此,我们批判性地分析了城市水域中MP和NP之间差异的当前进展。对MP和NP的分析挑战、命运、与周围污染物的相互作用以及生态影响进行了比较讨论。,与MP相比,NP的特征和命运研究更具挑战性。此外,在大多数情况下,与MP相比,NP与其他污染物的相互作用更强,对生物的不利生态影响更大。随后,提出了该领域的观点,以促进对MP和NP的进一步规模依赖性研究。这篇综述将有助于理解NP在城市水生态系统中的作用,并指导未来塑料污染管理的研究。

Nanoplastics are significantly different from microplastics in urban waters

Nanoplastics are significantly different from microplastics in urban waters

Microplastics (MPs) and nanoplastics (NPs) are ubiquitous and intractable in urban waters. Compared with MPs, the smaller NPs have shown distinct physicochemical features, such as Brownian motion, higher specific surface area, and stronger interaction with other pollutants. Therefore, the qualitative and quantitative analysis of NPs is more challenging than that of MPs. Moreover, these characteristics endow NPs with significantly different environmental fate, interactions with pollutants, and eco-impacts from those of MPs in urban waters. Herein, we critically analyze the current advances in the difference between MPs and NPs in urban waters. Analytical challenges, fate, interactions with surrounding pollutants, and eco-impacts of MPs and NPs are comparably discussed., The characterizations and fate studies of NPs are more challenging compared to MPs. Furthermore, NPs in most cases exhibit stronger interactions with other pollutants and more adverse eco-impacts on living things than MPs. Subsequently, perspective in this field is proposed to stimulate further size-dependent studies on MPs and NPs. This review would benefit the understanding of the role of NPs in the urban water ecosystem and guide future studies on plastic pollution management.
