A new study published in a peer-reviewed journal by the National Academy of Sciences suggests that bottled water purchased in the U.S. may contain 10 to 100 times more plastic particles than previously estimated. The research used a powerful optical imaging technique to analyze nanoplastics, finding an average of 240,000 plastic particles in two standard-sized water bottles. About 90% of these particles were nanoplastics, which can be toxic to human health. While the health implications of nanoplastics in bottled water are still unclear, the study raises concerns about plastic pollution in consumer products.
Experts recommend considering alternative options such as filtered tap water in glass or stainless steel containers.
