Tiny plastics in bottled water exceed prior estimates, study finds
A peer‑reviewed study in Science of the Total Environment found bottled water contains higher concentrations of microplastics and nanoplastics than treated tap water, with nanoplastics making up more than 50% of detected particles. Using advanced techniques like scanning electron microscopy and optical photothermal infrared spectroscopy, researchers warn that nanoplastics can cross cellular barriers and potentially reach organs, underscoring the need for better detection and consideration of alternatives to bottled water (e.g., filtered tap water or reusable bottles).
