Microplastic contaminations in a set of beverages sold in France
Chaïb I, Doyen P, Merveillie P, Dehaut A, Duflos G (2025). Journal of Food Composition and Analysis.
What they found
Mean levels were 2.9 microplastics per litre in water, 31.4 in colas, 28.5 in teas, 45.2 in lemonades, 82.9 in beers and 8.2 in wines. Drinks in glass bottles were the most contaminated. Most particles matched the colour and outer paint of the metal caps, which the authors suspect are the main source.
- Sample
- Water, soft drinks, beer and wine sold in France, in plastic, glass, carton, can and bag-in-box
- What it can't tell you
- Not a representative survey of French drinks (the authors say so). Brand and sample numbers, size cut-off and blank results were not checked because the full text is paywalled. Cap-paint particles are a specific source that may not apply to other countries or cap types. Measures contamination only.
