Bottled Water Contains More Plastic Particles Than Previously Thought
Researchers found hundreds of thousands of plastic particles in one-liter bottles of water sold in the US, 90% of them small enough to enter the human bloodstream.
A typical one-liter (33-ounce) bottle of water contains some 240,000 plastic fragments on average, according to a new study. Many of those fragments have historically gone undetected, the researchers determined, suggesting that health concerns linked to plastic pollution may be dramatically underestimated.
The peer-reviewed study, published Monday in the journal Proceedings of the National Academy of Sciences, is the first to evaluate bottled water for the presence of “nanoplastics” — plastic particles under 1 micrometer in length, or one-seventieth the width of a human hair. The findings show that bottled water could contain up to 100 times more plastic particles than previously estimated, as earlier studies only accounted for microplastics, or pieces between 1 and 5,000 micrometers.
