It has always been commented that plastic packaged drinks could contain more microplastic particles than those that go on glass. Well, a study carried out by the ANSES Food Security Laboratory in Boulogne-Sur -mer, In France, it has come to the conclusion that is the opposite.
This says the study on glass microplastics carried out in France
The researcher iseline chaib has justified the matter like this: “The particles detected in the glass coincided in shape, color and composition with the paint of the metal plugs used to seal the bottles”The study of the French laboratory analyzed several glass -packaged drinks such as Water, soft drinks, wine, beer and ice tea.
Microplastic particles
The analysis concludes that they cannot clarify for sure if there are real health risks, But the Microplastic levels in the analyzed They are more than obvious, putting as an example the water in the water (4.5 particles per liter in glass bottles and 1.6 in plastic or cardboard containers). The wine also obtained low levels of these, even in cork bottles.
The experts came to the conclusion that The microplastics present in glass bottles, a priori come from the painting of the metal plugs. They made sure to reach the coincidence between the particles found in drinks and paint paint, In addition, the caps had microscopic scratches, caused by friction during storage prior to use.
To check it, experts They did evidence in which they cleaned bottles and wearing plugs that submitted it to several treatments: In the bottles sealed with unleaded plugs, an average of 287 particles per liter were found, reducing to 106, by blowing compressed air between the plugs, already 87, when combining the blown with rinse with filtered water and alcohol.
In this way, the study carried out states that They would have to take measures such as improving the storage of the plugs To reduce friction or modify the paint used, in order to minimize pollution by microplastics in glass drinks.
