Contaminant Release from Aged Microplastic
Summary
Aged microplastics in the environment accumulate and release contaminants through sorption and desorption processes, acting as both reservoirs and delayed-release vectors for pollutants. As plastics weather over time, their increasing surface area and altered chemistry enhance contaminant uptake and release, meaning older environmental microplastics pose escalating toxicological risks to wildlife and humans.
Microplastics (MPs) have become one of the most pervasive emerging pollutants in the environment because of their wide occurrence and high sorption ability for contaminants. Sorption and desorption by microplastics may play important roles in the fate of contaminants...
