Abstract

Microplastic pollution in groundwater systems has garnered significant global attention. Understanding the factors and mechanisms that influence microplastic migration in groundwater is crucial for accurately assessing their distribution and environmental risks. As microplastic pollution in groundwater environments is a relatively new area of study, research is still in its early stages. There are limited reports on the abundance, polymer types, sizes, and other characteristics of microplastics in this field. The strong heterogeneity, complexity, and obscurity of the environment present numerous challenges for conducting related research. In this context, this article reviews the sources, distribution characteristics, potential risks, and removal strategies of microplastics in groundwater environments. It also emphasizes the existing knowledge gaps in the sampling processes and the environmental behavior of microplastics in groundwater. It systematically elucidates the factors influencing microplastic migration in groundwater and analyzes the mechanisms that affect this migration. Exploring the transport mechanisms of microplastics in groundwater aquifers is crucial for assessing their potential harm to the ecological environment and for implementing effective measures to combat microplastic pollution. Additionally, to gain a deeper understanding of the transformation behavior and environmental effects of microplastics in groundwater, a systematic summary and analysis of the current research shortcomings and deficiencies regarding microplastics in the groundwater environment will be conducted, along with a discussion of future research directions.

地下水中微纳塑料的研究进展：发生、环境影响及控制策略

地下水系统中的微塑料污染已经引起了全球的广泛关注。了解影响地下水微塑料迁移的因素和机制对于准确评估其分布和环境风险至关重要。由于地下水环境中的微塑料污染是一个相对较新的研究领域，研究仍处于早期阶段。在这一领域，关于微塑料的丰度、聚合物类型、尺寸和其他特性的报道有限。环境的强烈异质性、复杂性和模糊性为开展相关研究提出了许多挑战。本文综述了地下水环境中微塑料的来源、分布特征、潜在风险及去除策略。它还强调了在采样过程和地下水中微塑料的环境行为方面的现有知识差距。系统阐述了地下水中微塑性迁移的影响因素，分析了影响微塑性迁移的机理。研究微塑料在地下水含水层中的运移机制，对于评估微塑料对生态环境的潜在危害以及采取有效措施防治微塑料污染具有重要意义。此外，为了更深入地了解地下水中微塑料的转化行为和环境效应，系统总结和分析目前地下水环境中微塑料研究的不足和不足，并对未来的研究方向进行讨论。

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
