Microplastics (MPs) have been found to be widely distributed in aquatic environments, where they will interact with toxic heavy metals and result in more serious adverse effects on the aquatic environments and organisms. However, after entering the aquatic environments, MPs are quickly covered by biofilms, which significantly modify MPs properties and relevant heavy metals adsorption-desorption characteristics In order to better understand the adsorption behavior of heavy metals on biofilm developed MPs (BMPs), we comprehensively reviewed representative studies in this area. First, we summarized the formation process of biofilms on MPs. Subsequently, we reviewed the current understanding on the influence of biofilm formation on the properties of MPs and discussed the metal adsorption-desorption characteristics of MPs affected by these changes. Finally, based on the systematic literature review, some future research needs and strategies were proposed to further understand the interactions between MPs and heavy metals.
微塑料（MPs）已被发现广泛分布于水生环境中，在那里它们会与有毒重金属相互作用，对水生环境和生物造成更严重的不利影响。然而，进入水生环境后，微塑料很快就会被生物膜覆盖，这会显著改变微塑料的性质以及相关重金属的吸附-解吸特性。为了更好地理解重金属在生物膜包裹微塑料（BMPs）上的吸附行为，我们全面回顾了该领域的代表性研究。首先，我们总结了微塑料上生物膜的形成过程。随后，我们回顾了目前对生物膜形成对微塑料性质影响的理解，并讨论了受这些变化影响的微塑料的金属吸附-解吸特性。最后，基于系统的文献综述，提出了一些未来的研究需求和策略，以进一步了解微塑料与重金属之间的相互作用。
