Limited knowledge is available on the interactions between heavy metals and microplastics (MPs), as well as potential biological impacts from their combinations. Factors influencing the adsorption of heavy metals on MPs, such as polymer properties and chemical properties of heavy metals, are important to consider. Potential combined toxic effects from MPs and heavy metals on organisms and human health are a key focus for further research.
Although individual toxicity of microplastics (MPs) to organism has been widely studied, limited knowledge is available on the interactions between heavy metals and MPs, as well as potential biological impacts from their combinations. The interaction between MPs and heavy metals may alter their environmental behaviors, bioavail-ability and potential toxicity, leading to ecological risks. In this paper, an overview of different sources of heavy metals on MPs is provided. Then the recent achievements in adsorption isotherms, adsorption kinetics and inter-action mechanism between MPs and heavy metals are discussed. Besides, the factors that influence the adsorp-tion of heavy metals on MPs such as polymer properties, chemical properties of heavy metals, and other environmental factors are also considered. Furthermore, potential combined toxic effects from MPs and heavy metals on organisms and human health are further summarized. (c) 2021 Elsevier B.V. All rights reserved.
