About 10 to 100 times more nanoplastics than microplastics were discovered in bottled water, the study found. AdvertisementScientists said they're cutting back on bottled waterThe inside of an optical box reveals the components that organize the light from laser beams to identify nanoplastics, microscopic plastic pieces. Related storiesAll four co-authors interviewed said they were cutting back on their bottled water use after they conduced the study. Wei Min, the Columbia physical chemist who pioneered the dual laser microscope technology, said he has reduced his bottled water use by half. Previous studies looking for microplastics and some early tests indicate there may be less nanoplastic in tap water than bottled.
