The huge and growing toll bottled water is taking on human and planetary health warrants an urgent rethink of its use as 1 million bottles are bought every minute around the globe, with that figure set to rise further still amid escalating demand, warn population health experts in a commentary published in the open access journal BMJ Global Health.
Some 2 billion people around the world with limited or no access to safe drinking water rely on bottled water. But for the rest of us, it's largely a matter of convenience and the unshaken belief—aided and abetted by industry marketing—that bottled water is safer and often healthier than tap water.
It isn't, insist the authors from Weill Cornell Medicine in Qatar.
That's because bottled water often isn't subject to the same rigorous quality and safety standards as tap water, and it can carry the risk of harmful chemicals leaching from the plastic bottles used for it, especially if it's stored for a long time, and/or exposed to sunlight and high temperatures, they explain.
Between an estimated 10% and 78% of bottled water samples contain contaminants, including microplastics, often classified as hormone (endocrine) disruptors, and various other substances including phthalates (used to make plastics more durable) and bisphenol A (BPA).
Microplastic contamination is associated with oxidative stress, immune system dysregulation, and changes in blood fat levels. And BPA exposure has been linked to later-life health issues, such as high blood pressure, cardiovascular disease, diabetes and obesity, they add.
"While there are short-term safety thresholds, the long-term effects of these contaminants remain largely unknown," observes the author, adding that microplastics can also enter the food chain.
