Dissolved organic matter (DOM) exists widely in natural water, which inevitably influences microplastic (MP) photoaging. Nevertheless, the impacts of DOM fractions with diverse molecular structures on MP photoaging remain to be elucidated. This study explored mechanisms polylactic acid (PLA)-MPs and polystyrene (PS)-MPs presence its subfractions (hydrophobic (HPOA), hydrophobic neutral (HPON), hydrophilic (HPI)). Across fractions, HPI exhibited highest electron accepting capacity (23 μmol e

Biodegradable plastics (BPs) are promoted as eco-friendly alternatives to conventional plastics. However, compared microplastics (MPs), they degrade rapidly into biodegradable (BMPs), which may lead a more significant accumulation of BMPs in the environment. This review systematically compares and MPs, summarizes current knowledge on their environmental behaviors impacts ecosystems human health, offers recommendations for future research. detected water, sediments, indoor dust, food, marine organisms, samples. Compared prone transformations, such photodegradation biodegradation, results shorter migration distance across different matrices. Like can adsorb pollutants transport them enhancing toxicity health risks through Trojan horse effect. Studies indicate that negatively impact terrestrial aquatic than MPs by disrupting nutrient cycling inhibiting plant animal growth. In vivo vitro research also shows BMP degradation products increase bioavailability, exacerbating neurotoxicity overall toxicity. findings BMPs' effects remain inconsistent. Further evaluation trade-offs between biodegradability is needed address these uncertainties.
