Using advanced microscopy, researchers detect over 240,000 plastic particles per liter in bottled water – mostly hazardous nanoplastics below 1 micron. This reveals far higher human exposure than presumed, warranting research on toxicity and regulation. Sweating therapies may help eliminate accrued microplastics.
A startling new study by researchers at Columbia University reveals extraordinarily high levels of micro and nanoplastics in commercial bottled water, with major implications for human health1. Using an advanced microscopy technique called stimulated Raman scattering (SRS) spectroscopy, the scientists achieved unprecedented detection sensitivity to spot individual plastic particles down to 60-100nm – smaller than the wavelength of light2.
