Summary

Researchers combined Raman spectroscopy, laser induced breakdown spectroscopy (LIBS), and principal component analysis (PCA) to detect and identify polystyrene microplastics in commercially bottled drinking water. Spectral results were validated against standard polystyrene samples, demonstrating the potential of multi-technique spectroscopic analysis for routine microplastic identification in consumer water products.
