Scientists Discover 100 To 1000 Times More Plastics In Bottled Water (washingtonpost.com) 204

An anonymous reader quotes a report from the Washington Post: People are swallowing hundreds of thousands of microscopic pieces of plastic each time they drink a liter of bottled water, scientists have shown -- a revelation that could have profound implications for human health. A new paper released Monday in the Proceedings of the National Academy of Sciences found about 240,000 particles in the average liter of bottled water, most of which were "nanoplastics" -- particles measuring less than one micrometer (less than one-seventieth the width of a human hair). [...]

The typical methods for finding microplastics can't be easily applied to finding even smaller particles, but Min co-invented a method that involves aiming two lasers at a sample and observing the resonance of different molecules. Using machine learning, the group was able to identify seven types of plastic molecules in a sample of three types of bottled water. [...] The new study found pieces of PET (polyethylene terephthalate), which is what most plastic water bottles are made of, and polyamide, a type of plastic that is present in water filters. The researchers hypothesized that this means plastic is getting into the water both from the bottle and from the filtration process.

Researchers don't yet know how dangerous tiny plastics are for human health. In a large review published in 2019, the World Health Organization said there wasn't enough firm evidence linking microplastics in water to human health, but described an urgent need for further research. In theory, nanoplastics are small enough to make it into a person's blood, liver and brain. And nanoplastics are likely to appear in much larger quantities than microplastics -- in the new research, 90 percent of the plastic particles found in the sample were nanoplastics, and only 10 percent were larger microplastics. Finding a connection between microplastics and health problems in humans is complicated -- there are thousands of types of plastics, and over 10,000 chemicals used to manufacture them. But at a certain point, [...] policymakers and the public need to prepare for the possibility that the tiny plastics in the air we breathe, the water we drink and the clothes we wear have serious and dangerous effects.
"You still have a lot of people that, because of marketing, are convinced that bottled water is better," said Sherri Mason, a professor and director of sustainability at Penn State Behrend in Erie. "But this is what you're drinking in addition to that H2O."

    Do my cans of seltzer water have this problem? They're aluminum but I think they might be lined with plastic.

    • And if they around lined with plastic, are you possibly drinking thousands of nanoparticles of aluminum? And what does that do to your system?

    • by gweihir ( 88907 )

      According to the paper, most of the particles are not PET and hence are not from the bottle. And yes, both steel beverage cans and aluminum beverage cans are typically plastic lined.

      Aluminum leaches into water, too, and can have long term cognitive impacts.

    Alarmist headlines aside, it is good that we have finally reached the ability to mass-produce and deploy nanoparticles. This deployment will bring a new factor in human evolution and finally put us ahead of the degenerative AI and its robots.

    This is why I consume all my water intravenously.

  • You can taste it when you drink water from a plastic bottle, and that's why I don't. And I don't have a particularly discerning sense of taste, which is why I've always found it puzzling why people choose to drink water from cheap plastic bottles.

    • Tap water in most areas I've tried it in has a strong chlorine taste. Regular basic filtration doesn't do much. I don't really taste plastic on bottled water from most brands unless they've been left sitting in the sun. But given the choice I'd still pick a faint plastic taste over the taste of chlorine.

      • by gweihir ( 88907 )

        You typically need activated carbon to remove chlorine from water. You may want to think about why that chlorine is in there. Better make sure to very carefully filter for biological contamination as well.

        • by ls671 ( 1122017 )

          I mean come on, the chlorine evaporates in 15 minutes at the very maximum. Fluoride is a different story although, tap water is very good quality where I live so I put glass bottles of tap water into the fridge without the caps and put the caps on after a few hours, all chlorine is gone. I don't fill the bottle to the neck so water surface has more air contact. As I said, fluoride is harder to get rid off although but luckily my water treatment plant say they don't add fluoride to tap water.

          Same principle a

            Sure, if you have the time/patience, that works as well. If you want it inline, activated carbon it is.

            • by ls671 ( 1122017 )

              Just put it in the fridge in advance, I have multiple bottles in there and do a rotation. When one bottle is empty, I simply refill it. I always have water available and no need to be patient. Also, not sure how activated carbon would automagically and instantaneously evaporate and remove chlorine from the water but it might, I don't know. Anyway, different studies have shown that those filter quickly become packed with bacteria, mold and what not so it's a big no no for me. Simply have your filter analyze

      The main body of particles is not PET. These are not from the bottle.

    • Take a swig of my tap water and you will understand why I use bottled. Not to mention people who have wells tainted with iron. If you're a city boy you may not have had a big drink of iron water, but it's unpleasant to say the least.

    Nanoplaastics must be really healthy, when you consider how long people are living these days compared to say 200 years ago. Up until the 2000s, no ex-president lived even to age 91 (there's been over 40 presidents btw). Since the year 2000 -- presidents born after , we've been had at least 4 ex-presidents who lived past age 91.

    • This is probably one of the better examples of how correlation != causation that I've heard.

    • by skam240 ( 789197 )

      Of course the people living until 91 today didn't grow up in a world where everything was packaged in plastic like today.

      Your data set is laughable too. "Well we've had some presidents who lived a long time", as if presidents, who are almost always wealthy, are a large enough and / or representative enough data set to come to any conclusion with.

      Then again, going by the language you're using you're probably not trying to make an honest point here.

    • by gilgongo ( 57446 )

      The first ten men mentioned in the Bible, Adam through Noah (except Cain and Abel), lived on average more than 850 years (Genesis 5: 1-32). Methuselah lived for 969 years. This was the maximum, but by no means exceptional. However, while God fixed the modern living day of man to 120 years, plastics have clearly out-Godded her.

      • Have you ever noticed that when you take those years to be months, which would make sense for a couple of reasons, not the least being that the stories likely come from a time when people were more likely to count months rather than years because they were more important for their survival, those insane time spans suddenly start to look quite reasonable?

    • Well, duh! Don't you know that plastics are practically indestructible and it takes centuries for them to break apart? Once you're 100% lined with plastic on the inside, you're immortal!

  • Does the type of bottle make a difference?

    I buy Propel water in 24 ounce bottles. They seem identical to pop bottles.
    (Not like the thin plastic bottles you get with (insert generic water brand here) 500ml )

    The town water supply is suitable for washing, but I am not going to drink it.

    My wife drinks Smartwater in 1 litre bottles.

    • by gweihir ( 88907 )

      According to the paper, it is not PET that makes the largest section of particles. So this is not from the bottle.

    • If you stick to the most expensive brands you're good to go. Tell your wife to keep drinking that Smartwater and her IQ will skyrocket like yours.

  • The water that is delivered to your faucet very likely travels through pipes made of PVC or PEX (plastics), copper, iron, or even lead. ALL of these types of pipe may leach plastics or metals into your drinking water.

    You'd better stop drinking water now, from any source, if you want to protect yourself!

    • Now why don't you just take it easy, Tony, and please make me a drink of grain alcohol and rainwater, and help yourself to whatever you'd like.

      • Wait, rainwater? The kind with acid in it? And what container are you going to drink this grain alcohol from?

        • I drink only distilled water, or rain water to replenish my precious bodily fluids. And only pure grain alcohol, straight from the cask.

      • Rainwater! Every drop of rainwater coalesces around a dust particle. Who knows what you are getting.

      Most common particle in the paper was PS. It is not the pipes or the bottles.

      • Article is paywalled.

        I don't think the study established anything about how much stuff you drink, that leeches from your pipes. We do know that pipes leech, as demonstrated by Flint, Michigan.

    After only 30 years of drinking bottled water, patients' veins begin to stand out on the backs of their hands. At forty years, muscle mass begins to decrease and belly fat starts to form. After fifty years hair turns grey and can even fall out. Before sixty years of drinking this stuff, women can no longer bear children and men may have potency problems. After eighty years the rate of death increases exponentially and is often preceded by dementia. Not a single user of bottled water has survived past 110.

    This scourge must be stopped now!

  • Kidding aside, this does freak me out. It makes sense on a microstructural level that there would be consequences.

      The intent of this news is indeed to freak people out. However, no analysis of consequences has yet been undertaken. Depending on one's viewpoint, that lack of knowledge is either frightening or comforting.

      • I'm usually a massive optimist, but my intuition / knowledge of basic physics causes me some concerns. If non-biodegradable materials are building up in our bodies, that's going to present some challenges for our physiology, given that we evolved without them in the picture. Particularly structural challenges.

        Life finds a way eventually, but that way doesn't necessarily involve humans. And I would prefer that it does involve humans.
      • The intent of this news is indeed to freak people out.

        Is that why right near the top of the article it says clearly that the impact of this on people is unknown? The only people who get freaked out by most news are idiots who read headlines and then run and hide under the couch. That doesn't mean news is intended to freak people out, it means we should tell people to harden the fuck up and address their short attention spans.

    • Oh man, kidding aside have I got news for you: https://www.wired.com/story/pl... [wired.com]

      I stopped drinking water altogether. To risky. Beer is a good alternative.

  • How about going back to glass bottles for drinks which were common a couple of decades ago (before plastic took over).

    • by gweihir ( 88907 )

      It is mostly _not_ PET and hence mostly cannot be from the bottles.

    • The plastic bottles cost less and use less energy to make than glass. They also are less likely to break, and if they do the debris is less dangerous.

    Joke comments aside, there has been significant decline in male testosterone levels (look it up, it's easy to find and I mentioned this before and quoted the relevant papers) in the past 30 years, and phtalates seem to be one of the reasons why this is as they are endocrine disruptors.

    Decline in testosterone in males lead to infertility, muscular atrophy, easier to gain fat / obesity... and plethora of other issues.

    But yeah... let's joke how it's all good since nobody turned into a plastic man yet.

    It is possible to do something about this (finding better sources of water).

      We don't even know that there is anything to do something about yet.

      We could try to do better studies, comparing people who drink from plastic bottles against those who don't (while handling all the confounding factors ...) but screeching "100 to 1000 more!" (than what?) is pretty meaningless.

    BTW, plastics production is increasing, year on year, at a pretty steep rate. About 2% of it ever gets recycled & the rest goes into the ground or the sea. Some plastics release even more harmful chemicals if you burn them.

    People are easily agitated by gloom-and-doom articles like this, and they are useful to SOMEBODY.

    Remember: in huge regulatory matters, BILLIONS of dollars and many careers may be on the line (on either or BOTH sides of the arguments).

    This one admits "Researchers don't yet know how dangerous tiny plastics are for human health.", "...there wasn't enough firm evidence linking microplastics in water to human health...", and "Finding a connection between microplastics and health problems in humans is complicated..." but then goes on to presume "... policymakers and the public need to prepare for the possibility that the tiny plastics in the air we breathe, the water we drink and the clothes we wear have serious and dangerous effects."

    I am NOT saying the plastics detected are safe....I am just pointing out that somebody wanted this article written and distributed and it points people in a certain direction (presuming harm, and asserting a need for future regulation) before anybody has even established that the presumed problem is actually a real problem. It MIGHT be a problem. It SOUNDS bad. Any action taken will have a definite impact on a great many people. Some companies may be destroyed, some people may lose their jobs, suffer financial losses, families may break up, kids may lose options for college as their parents suffer financially, supply chains may get disrupted, products people count on may become unavailable, etc. These actions have a myriad of spin-off effects that are often not predicted. As a result, we need to make sure something IS a problem before we decide to treat it as one.

      I find it funny how on the one hand "markets decide who is best, bad companies fail" and then when we decide to change the market conditions for reason XYZ, "think of the companies! the Jobs!" I mean, how is regulating something to oblivion different from a foreign company overtaking the market, or a drought preventing operation?

  • "Researchers don't yet know how dangerous tiny plastics are for human health" I suspect they are completely benign and pass right thorough us. and then wont you all fell silly for your knee jerk, unfounded reactions.. Sadly I know you wont, you will just shift your attention onto the next "its bad for you fad" You know whats is bad for the planet?, its people!. So do the planet a favour and get yourself mulched and spread on some plants
