ClearRaman spectroscopy for microplastic detection in water sources: a systematic review
This systematic review summarizes how Raman spectroscopy, a type of light-based analysis, is used to identify microplastics in drinking water, oceans, and wastewater. Polystyrene, polyethylene, and polypropylene were among the most commonly detected plastics across all water sources. Better detection methods like this are essential for understanding the extent of microplastic contamination in the water we drink.
