Plastic Fibers Found In 83 Percent of World's Tap Water, Study Reveals (theguardian.com) 210

Posted by BeauHD from the triple-filtered dept.
Robotron23 writes: Research published by Orb Media, a nonprofit journalism group, has revealed that microplastics have contaminated high proportions of drinking water and bottled water. Samples from the United States tested positive in 94% of instances, while Europe's contamination averages around 72%. Tests were undertaken at the University of Minnesota School of Public Health, with lead researcher Dr. Anne Marie Mahon noting the risk of plastics carrying bacteria, and commenting: "In terms of fibers, the diameter is 10 microns across and it would be very unusual to find that level of filtration in our drinking water systems." As for the culprit, the report mentions the atmosphere as one obvious source, "with fibers shed by the everyday wear and tear of clothes and carpets." Another potential source is tumble dryers, "with almost 80% of U.S. households having dryers that usually vent to the open air." Overall, the investigation by Orb Media found that 83% of the samples were contaminated with plastic fibers.

      • Even so....are people now wearing plastic clothes??

        All my stuff is cotton....what is considered "plastic" clothing that a dryer would vent dangerous lint out...?

        • You do realise that nylon has been in use in clothing for 70 years or so? And that synthetic polyamide is only one of many synthetic fiber types?

          • Ok....I wasn't thinking of nylon as "plastic"...just didn't hit the brain right. When I think plastic, I think water bottle or even vinyl type stuff.....

            • Well, you certainly have heard of polyester clothing. That is exactly the same plastic that is used for water bottles, this is what makes bottle reclycling so practical.

    • Something's up with that. I would suspect that 99.9995% of US dryers vent to open air.

      Don't you have non venting driers in the US? They're substantially more expensive, but also much much more efficient.

          Modern ones use the latent heat of condensation to warm incoming air, saving on electricity. They are about twice as efficient in power terms as a 'normal' dryer, although they do take longer to dry clothes.

            Which means the clothes tumble longer, which increases wear. It's easy to calculate kW-hr saved per year. Evaluating the cost of clothes wearing out slightly faster is a more difficult problem that most people won't be considering. Maybe it is worth it, maybe not.

      Mine vents to the garage. House was built in '81. Seems like they should have known better by then. I'll admit it's sort of nice in the winter, but it's a terrible idea in the summer.

      My upstairs bathroom fan vented to the attic, rather than out the roof. Again, I understand that was acceptable at the time, but it seems like a bad idea and we fixed that one.

      I will gladly hear how plastic particles can get through a nano filtration or reverse osmosis filtration as physically there is no way a micro meter particule size can go through the pore size (you understand that for reverse osmosis even Na+ ion cannot go through it....). Is it some form of quantic tunnelling not seen before?

      • They don't have to get through the filter; the filter is likely shedding plastic as well at a certain scale roughly proportionate to this.

    • Just because the fibers are ubiquitous doesn't mean that Morgellon's isn't delusional. Wifi is everywhere, but it doesn't mean the people that are allergic to wifi when the activity light is on aren't delusional.

    Directly looking at the website of the researchers indicates to me that this hasn't been published in a peer-reviewed journal yet. And the quality of the post is egregious: "83% of the samples were contaminated with plastic fibers" means practically nothing if we do not also get to know the size of the samples versus the amount and size of the fibers, and their composition.

    The actual research, if and when published, could be very interesting. This grab for views --- not so much.

    My home is fed by my own private well and the water gets filtered by a reverse osmosis filtration system. Certainly not foolproof, but plastic fibers are likely the least of your worries in the public water system. I'd be a lot more concerned about pharmaceuticals in the water supply....like anti-depressants.

    Plastic of all shapes and sizes is literally everywhere people go. Take a walk around your neighborhood sometime and just start picking up any random garbage you see. You'll be surprised just how much you pick up in just a few hundred square feet. Plastic pieces of all colors, shapes, and sizes. Bags. Lids. Shards. Parts of toys. Unidentified stuff...

    The stranger part to me is that so many educated people don't care at all about the issue, even though it is just as important as climate change and other forms of toxic pollution due to the enormous amounts of it we're putting into the environment every day. Even here, there will be many comments along the lines of, "Yeah, yeah, plastic in the water is bad - but I'm more worried about X in the water."

      Plastics that don't dissolve in stomach acid won't get absorbed by the intestines, so I imagine they'll just pass through. Breathing it in is probably worse for you. Some fibrous materials like asbestos can cause cancer. The complication is how many different kinds of plastics there are, some might be entirely harmless, others not so much.

Once upon a time we were out in the wild eating rancid raw meat and drinking from contaminated water sources on a regular basis much the same as other animals. From an evolutionary standpoint, we evolved to be able to deal with a lot of impurities being filtered out as a matter of survival. Now granted, we do see evidence that at some point we have lost some of our ability to do this. For example, our appendixes no longer wo

    Add a UV steriliser for $70 or so and that kills most if the living stuff.

    In March I installed one of these undersink filters [rainfresh.ca] which is rated at 0.3 micron. That's a particularly good one unless you go with reverse osmosis. 0.3 micron will filter out bacteria, but not viruses. Obviously it will filter out these 10 micron plastic fibers too. So far the filter has lasted this long with no change. Even a more basic undersink filter will typically filter down to 5 microns [rainfresh.ca].
