Glass Bottles Found to Contain Higher Levels of Microplastics, Study Reveals
…………….

A new study has found that beverages in glass bottles may contain significantly more microplastic particles than those in plastic bottles or metal cans. Researchers, including experts from France’s food safety agency ANSES, discovered an average of 100 microplastic particles per litre in drinks packaged in glass—five to 50 times higher than in plastic bottles.

This unexpected result points to the paint on bottle caps as a likely source of contamination. Scientists suggest that cleaning new caps before sealing bottles could substantially reduce microplastic levels. The findings highlight the need for improved manufacturing practices to limit microplastic exposure.
