Resin Pellets Aging and Degradation Investigation from Long Term in Situ Experiment: First Results

Summary

Researchers conducted long-term in situ aging experiments on resin pellets — a major category of primary microplastics — to track their physical and chemical degradation over time in real-world conditions. Understanding how pellets degrade in the environment helps predict when and how they fragment into smaller, more bioavailable particles capable of entering food chains and human bodies.
