The Impact of Aging on the Physicochemical Properties, Environmental Processes and Toxic Effects of Microplastics
Microplastic pollution has become a major environmental issue of global concern. Microplastics can undergo aging under various environmental conditions. The aging process will change the physical and chemical properties of microplastics, thereby leading to changes in their environmental behaviors and toxicities. Therefore, exploring the aging process and mechanism of microplastics is of significance for understanding the environmental processes and health risks of microplastics. This article focuses on the aging process of microplastics in the environment and reviews it from the aspects of aging pathways, influencing factors, interactions with pollutants, release of chemical substances, and changes in toxicities. It also looks forward to the existing challenges and future research directions in the current studies on microplastic aging.
