Microplastics in Drinks: Glass Bottles Surprisingly Higher Than Plastic?

A French ANSES study revealed surprisingly high microplastic contamination in glass bottled drinks compared to plastic or canned counterparts, particularly cola, lemonade, iced tea, and beer. Glass bottles averaged around 100 microplastic particles per liter, while plastic and cans showed significantly lower levels (5 to 50 times less). The source? Microplastics likely originate from the paint on bottle caps, released by microscopic scratches from storage friction. Cleaning caps significantly reduced contamination. The study suggests manufacturers explore altering cap storage or paint composition to mitigate this issue.
