Microplastics (MPs) have recently attracted much attention due to their widespread distribution in the aquatic environment. Microplastics can act as a vector of heavy metals in the aquatic environment, causing a potential threat to aquatic organisms and human health. This review mainly summarized the occurrence of microplastics in the aquatic environment and their interaction with heavy metals. Then, we considered the adsorption mechanisms of MPs and heavy metals, and further critically discussed the effects of microplastics properties and environmental factors (e.g., pH, DOM, and salinity) on the adsorption of heavy metals. Finally, the potential risks of combined exposure of MPs and heavy metals to aquatic biota were briefly evaluated. This work aims to provide a theoretical summary of the interaction between MPs and heavy metals, and is expected to serve as a reference for the accurate assessment of their potential risks in future studies.
微塑料（MPs）由于其在水环境中的广泛分布，最近引起了广泛关注。微塑料可以作为水环境中重金属的载体，对水生生物和人类健康构成潜在威胁。本综述主要总结了微塑料在水环境中的存在及其与重金属的相互作用。然后，我们考虑了 MPs 和重金属的吸附机制，并进一步批判性地讨论了微塑料性质和环境因素（如 pH 值、DOM 和盐度）对重金属吸附的影响。最后，简要评估了 MPs 和重金属联合暴露对水生生物群的潜在风险。这项工作旨在为 MPs 和重金属之间的相互作用提供理论总结，并有望为未来研究中准确评估它们的潜在风险提供参考。
