Nanoplastic in bottled water

A liter of bottled water contains 240,000 plastic particles. Previous estimates for this indicator were approximately 100 times lower. Chemists have studied water from three brands and found plastic particle counts ranging from 110,000 to 370,000 in the samples. About 90% of them are nanoplastics, which are fragments smaller than one millionth of a meter. The study authors argue that nanoplastics may be more harmful to health than microplastics, as polymer nanoparticles can penetrate into cells, bloodstream, and affect internal organs.
