Study finds nanoplastic particles in bottled water

A study reveals that each liter of bottled water contains 110,000 to 370,000 nanoplastic particles, with approximately 90% being nanosized. These particles pose a greater health risk than microplastics, as they can enter the bloodstream, raising concerns about potential health impacts. The quantity of nanoplastics in bottled water is estimated to be 10 to 100 times greater than previous estimates. The study identified seven plastic compounds, including PET used in disposable bottles, with polyamide outnumbering PET, potentially introduced by water purification filters. The health effects of consuming water with nanoplastics require further research, emphasizing the importance of considering alternatives like tap water, according to Beizhan Yan, one of the study's authors from Columbia University.
