Researchers discovered thousands of nano-sized bits of plastic in bottled water

It seems anywhere scientists look for plastic, they find it: from the ice in Antarctica, to the first bowel movement produced by newborn babies.

Now, researchers are finding that the amount of microscopic plastics floating in bottled drinking water is far greater than initially believed.

Using sophisticated imaging technology, scientists at Columbia University’s Lamont-Doherty laboratory examined water samples from three popular brands (they won’t say which ones) and found hundreds of thousands of bits of plastic per liter of water.

Ninety percent of those plastics were small enough to qualify as nanoplastics: microscopic flecks so small that they can be absorbed into human cells and tissue, as well as cross the blood-brain barrier.

The research, which was published Monday in the journal Proceedings of the National Academy of Sciences, raises new concerns about the potentially harmful health effects — and prevalence — of nanoplastics. The researchers found that the quantity of such particles was 10 to 100 times greater than previously estimated.

    We don’t know just how bad it is. We have every reason to believe we will find out that it causes cancer, hormonal problems, whatever else you can imagine. Limited studies show that certain plastics cause certain health problems… probably.

    But as of now there is no smoking gun evidence. Until there is, we are just going to continue to use it and hope that it is inert. I don’t know about you, but I don’t feel particularly lucky…

    Here is what AI has to say…

    "There is no definitive evidence that plastic is bad for our health, but there is growing concern that plastic may pose various health risks at different stages of its life cycle. According to a report by the Center for International Environmental Law², plastic and its impact on human health is poorly understood, but research to date has found that plastic can cause or contribute to:

    • Cancers, lung disease, and birth defects from the extraction and transport of fossil fuels used to make plastic³.
    • Metabolic disorders, reduced fertility, and hormone disruption from the chemicals added to plastic or leached from plastic into food and beverages¹.
    • Respiratory problems, cardiovascular diseases, and cancer from the toxic emissions and ash produced by burning or incinerating plastic waste².
    • Inflammation, tissue damage, and potential transfer of pollutants from the ingestion or inhalation of microplastics in the environment².

    These health impacts are not only affecting humans, but also wildlife and ecosystems that are exposed to plastic pollution. Plastic is everywhere, and it is not going away anytime soon. Therefore, it is important to take action to reduce plastic production, consumption, and disposal, and to support more research on the health effects of plastic. 🌎

      That report from CIEL is damning, wow. Well, here’s to hoping that all works out well for the future… I think the effects scientists are seeing in rats is a decent indication of what we’ll see, and seeing the spread of plastic classified and broken down - it’s basically become unavoidable for people, and ultimately we’re all ingesting more and more petroleum over time, with seemingly fuck all we can do about it I’m pretty uncomfortable right now.
