Research progress on aging technology,characteristics and toxic effects of microplastics
Microplastics(MPs)in the environment are usually affected by environmental factors such as ultraviolet radiation,thermal radiation,chemical oxidation,and biodegradation,and then undergo processes of photoaging,thermal aging,chemical aging,or biological aging.These processes potentially change the physicochemical properties of MPs to some extent.However,the natural aging process of MPs in the environment takes a long time,which greatly restricts the understanding of aging MPs.This paper reviewed the different laboratory-accelerated aging technologies of MPs,including UV aging,chemical aging,and biodegradation,and expounded on the changes in the surface characteristics,functional groups,and their effects on adsorbed pollutants of MPs after aging.We further summarized the effects of aging MPs on developmental toxicity,reproductive toxicity,neurotoxicity,and oxidative stress.This paper aims to provide a better understanding of MPs laboratory accelerated aging techniques and their potential risk effects on organisms.
