Microplastics (MPs) and metals are currently two of the most concerning environmental pollutants due to their persistent nature and potential threats to ecosystems and human health. This review examines the intricate interactions between MPs and metals in diverse environmental compartments, including aquatic, terrestrial, and atmospheric environments by focusing on the complex processes of adsorption and desorption and the mechanisms that govern these interactions. MPs act as carriers and concentrators of metals in aquatic and terrestrial environments, affecting the bioavailability and toxicity of these contaminants to aquatic and terrestrial organisms. This review highlights the existing challenges and constraints associated with current analytical methods, including microscopy, spectroscopy, and isotherm models in studying microplastic-heavy metal interactions. Moreover, we identified the knowledge gaps and future research directions that can enhance our understanding of the dynamic interplay between MPs and metals in various environmental settings.
微塑料（MPs）和金属目前是两种最令人担忧的环境污染物，因为它们具有持久性，并且对生态系统和人类健康构成潜在威胁。本综述通过关注吸附和解吸的复杂过程以及控制这些相互作用的机制，考察了 MPs 和金属在包括水生、陆地和大气环境在内的不同环境隔室中的复杂相互作用。MPs 在水生和陆地环境中充当金属的载体和浓缩剂，影响这些污染物对水生和陆地生物的生物利用度和毒性。本综述强调了与当前分析方法相关的现有挑战和限制，包括在研究微塑料-重金属相互作用时使用的显微镜、光谱学和等温热力学模型。此外，我们确定了知识空白和未来的研究方向，可以增强我们对各种环境中 MPs 和金属之间动态相互作用的理解。
