Emerging investigator series: microplastic-based leachate formation under UV irradiation: the extent, characteristics, and mechanisms.

ABSTRACT: Microplastics in the aquatic system are among the many inevitable consequences of plastic pollution, which has cascading environmental and public health impacts. Our study aimed at analyzing surface interactions and leachate production of six microplastics under ultraviolet (UV) irradiation. Leachate production was analyzed for the dissolved organic content (DOC), UV₂₅₄, and fluorescence through excitation emission (EEM) to determine the kinetics and mechanisms involved in the release of organic matter by UV irradiation. The results suggested there was a clear trend of organic matter being released from the surface of the six microplastics caused by UV irradiation based on DOC, UV₂₅₄ absorbance, and EEM intensity increasing with time. Polystyrene had the greatest and
