Migration of Metals from Microplastics into Simulated Gastric Fluid: The Role of Particle Size

Summary
Tiny plastic particles we accidentally swallow can leach metals into our stomach acid, and this study found that smaller plastic pieces release more metal than larger ones. That matters because as plastics break down into ever-smaller fragments in the environment, they may become more likely to release potentially harmful metals into our bodies when digested.
