Microplastics are ubiquitously distributed and persistently present in soil-water systems, posing potential ecological health risks worldwide. Free radicals highly reactive particularly at soil-water-air interface. The dynamic changes of free sensitive to environmental conditions may greatly impact the fate microplastics. However, pathways, reaction kinetics, or transformation products microplastic degradation by systems remains unclear. Climate change alters physical chemical environment this can directly affect microplastics, indirectly influence it altering generation species radicals. Here, we summarized analyzed fluctuations (such as superoxide radicals, hydrogen peroxide, peroxyl hydroxyl radicals) on microplastics their derivants. We also discussed how driven climate By integrating aspects such change, radical chemistry, pollution, work delineates critical issues pollution exacerbated condition changes. In response existing challenges deficiencies current research, feasible countermeasures proposed. This offers valuable insights for future research predicting controlling ecotoxicity caused associated with global change.

Abstract This study investigated the effects of different aging treatments (UV light, potassium permanganate, and sodium hydroxide treatments) on adsorption lead (Pb(II)) by PET microplastics, as well impact Microcystis aeruginosa microplastics. The results indicated that significantly affected capacity which could be attributed to increased functional groups surface porosity during process. Kinetic analysis revealed Pb(II) follows a pseudo-second-order model, suggested process is mainly controlled chemical adsorption. Intraparticle diffusion further elucidated migration mechanism within On other hand, presence enhanced As concentration microalgae increases, promoting effect microplastics gradually strengthens, with extracellular polymeric substances (EPS) secreted playing key role in facilitating These findings strengthen carriers heavy metal aggravate risk pollution aquatic ecological environment.
