Microplastics, due to their surface properties, porosity and electrostatic interactions have a high affinity for cations sorption from the aqueous phase. As soil is complex matrix, between microplastics, constituents heavy metals (HM) may modify microenvironment metal mobilization/immobilization processes. In order better understand problem, three commonly found forms of microplastics in (fibers, fragments microbeads) were mixed with Cu2+- or Pb2+-contaminated incubated at 22 °C 180 days. samples pH content water acid exchangeable species analyzed. The results this study showed that presence HM-contaminated affected speciation, increasing amount easily potentially bioavailable Cu2+ Pb2+ tested soil. Soil also increased, confirming microplastic particles affect properties relevant sorption/desorption process cations. Overall, smallest (≤1 mm), such as fibers glitter microbeads, had greater impact on change desorption conditions than larger particles. findings our show form, shape size should be considered important factors influence mobility

The studies on microplastics are significant in the world. According to literature, have greatly specific surface areas, indicating high adsorption capacities for highly toxic pollutants aquatic and soil environments, these could be used as adsorbents. influencing factors of microplastic adsorption, classification microplastics, mechanisms using adsorbing organic, inorganic, mixed summarized paper. Furthermore, influence pH, temperature, functional groups, aging, other related performances plastics discussed detail. We found that greater advantages efficient performance cost-effectiveness. In this paper, adsorptions by their is proposed, which provides guidance future research field.
