Polyvinyl chloride microplastic detection by single particle inductively coupled plasma mass spectrometry for the characterization of model microplastics

Summary

This study developed and validated a single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) methodology to detect and characterize PVC micro- and nanoplastics, producing model particles suitable for risk assessment studies. SP-ICP-MS represents an important analytical advance for PVC microplastic characterization, as PVC is one of the most widely used and toxic plastics, and reliable model particle standards are essential for standardized toxicological testing.
