Glass bottles may contain more microplastics than plastic ones, scientists warn
Up to 50 times more microplastics in glass-bottle drinks than plastic ones
- A new study indicates that beverages sold in glass bottles may contain significantly more microplastic particles than those in plastic bottles or metal cans.
- Researchers, including those from France's food safety agency ANSES, found an average of 100 microplastic particles per litre in glass bottles of various drinks.
- This level of contamination is surprisingly five to 50 times greater than that found in plastic bottles, a finding that contradicted scientists' expectations.
- The study suggests that the paint on bottle caps is the likely main source of microplastic contamination in glass bottles.
- Scientists recommend that glass bottle manufacturers clean new capsules before capping to significantly reduce microplastic contamination.
