Microplastics have been a major cause of concern for many people. Not only have many people made the switch to paper straws, plates or glass bottles, but people are also changing what kind of packages enter their homes. However, was that enough? It may not have been. Many of us assume that drinking from a glass bottle is better than a plastic one. However, a new study suggests this might not be true. The research found that some beverages in glass bottles actually have more microplastics—tiny plastic particles—than those in plastic bottles or cans. Scientists believe the caps on the glass bottles may be the main reason for this surprising finding. Microplastics are everywhere: in our oceans, soil, air, and even our bodies. They have been linked to health problems like infertility, hormone issues, and even cancer. This study challenges the idea that glass is automatically the safest option, and highlights that seemingly small parts of packaging, like caps, can be a big source of microplastic exposure. What Has Higher Chances Of Microplastic Exposure? To see how different containers affect microplastic levels, French researchers tested various drinks in different types of packaging. They looked at water, soda, iced tea, lemonade, wine, and beer. The results were surprising: Cola, Iced Tea, Lemonade, and Beer These drinks contained significantly more microplastics when they were in glass bottles. In some cases, there were nearly 50 times more microplastics than in plastic bottles and cans. Water Water in glass bottles had slightly more microplastics, but it was the least contaminated drink overall, no matter the container. Wine Wine in cardboard "brick" cartons had more microplastics, but generally, all the wines tested had very low levels of contamination. The study showed that the amount of microplastics a person is exposed to can vary widely depending on what they drink and what container it comes from. For example, a single liter of lemonade from a glass bottle might have over 100 microplastics, while the same amount of water from a plastic bottle might have only about 1.6. It’s important to note that the study only tested for microplastics and not even smaller particles called nanoplastics, which might have gone undetected. Why Are Glass Bottles Contaminated With Microplastics? It seems strange that a glass bottle would be more contaminated than a plastic one. The researchers were surprised by their own findings, but they have a theory: the cap. They believe the paint used on the metal caps of glass bottles may be the source. During testing, they noticed that the microplastics found in the drinks often had the same color and material as the paint on the caps. They also saw tiny scratches on many of the caps, suggesting that friction during bottling, storage, or sealing could cause the paint to flake off as microplastic particles. When the researchers cleaned the caps, the amount of microplastics in the drinks dropped significantly. The use of a cork on most wine bottles may also explain why wine had a much lower level of contamination. While cleaning the caps won't completely solve the problem—microplastics can also come from airborne particles, contaminated water, or factory equipment—the findings suggest that beverage companies should rethink their packaging to protect consumers. How Do Microplastics Affect Our Health? According to Association of American Medical Colleges although we don't have proof that microplastics harm humans, scientists are concerned. A study on mice found that even "clean" plastic particles caused negative effects. The worry is that real-world plastics contain harmful chemicals that disrupt hormones, which can affect important body functions like growth and reproduction. Experts suggest reducing plastic exposure as much as possible, especially for pregnant women and children. How to Reduce Your Microplastic Exposure?Given that microplastics are everywhere, it's almost impossible to avoid them completely. The study found that even bottled and tap water contain them. However, you can take steps to reduce your exposure: Use cups made of glass, stainless steel, or bamboo.Avoid putting plastic containers in the dishwasher or microwave, as heat can cause them to release microplastics into your food and drinks. When you buy a drink, consider switching between different types of packaging, like plastic, glass, and cans.The ultimate goal, experts say, is to reduce our overall dependence on packaged drinks and snacks in general.
