Researchers identify high levels of nanoplastics in bottled water

Columbia University researchers used laser-based imaging to detect an average of 240,000 plastic particles per liter in bottled water, mostly nanoplastics.

Experts suggest that physical friction from opening and closing bottle caps significantly contributes to the shedding of these tiny plastic particles into the water.

While health impacts remain under study, experts note that boiling water is ineffective for removal and advocate for advanced filtration at point-of-use.
