'Forever Chemicals' Found In 95% of Beers Tested In the U.S. (sciencedaily.com) 67

ScienceDaily reports: Forever chemicals known as PFAS have turned up in an unexpected place: beer. Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS, with the highest concentrations showing up in regions with known water contamination. The findings reveal how pollution in municipal water supplies can infiltrate popular products, raising concerns for both consumers and brewers...

[PFAS] have been found in surface water, groundwater and municipal water supplies across the U.S. and the world. Although breweries typically have water filtration and treatment systems, they are not designed to remove PFAS... [T]he researchers call for greater awareness among brewers, consumers and regulators to limit overall PFAS exposure. These results also highlight the possible need for water treatment upgrades at brewing facilities as PFAS regulations in drinking water change or updates to municipal water system treatment are implemented.

"I hope these findings inspire water treatment strategies and policies that help reduce the likelihood of PFAS in future pours," research lead Jennifer Hoponick Redmon said in a May announcement about their research.

    It's still up for debate how bad vaping by itself is but there's no debate that you shouldn't be breathing in lead and heavy metal. And I don't mean Judas Priest.

      Cheapest would obviously be if factories that produce PFAS would filter out their waste water, before it gets into the nature. It is very hard to find prices for industrial level PFAS filtering and there are currently several projects ongoing that try to make it cheaper, but for a household it is something like 250 dollars per year, so I think it would increase the cost of beer by 5 cents per liter or less, assuming you only need to filter the source water, not other materials that go into beer, which most

      To be honest, beer contains a chemical has been shown to be harmful without a doubt: ethanol. Yes, the reason many people drink beer in the first place. In addition to the obvious bad things that happen when you are drunk, it also causes cancer, birth defects, and a whole lot of other health issues, like cirrhosis. It also affects sperm counts by the way. And recent studies have shows that it is harmful at any dose, though obviously much worse at high doses.

    • People don't drink beer for their health;

      That doesn't mean people who drink beer don't care about their health. PFAS are bioaccumulating substances. The effects of beer if they don't do damage do get worn off. There's absolutely reason to avoid drinking beer from known PFAS hotspots.

      But with so many beers in the world, that shouldn't be too difficult. The point here is not that people need to avoid beer, it's more that fermentation doesn't break down PFAS (no shit Sherlock), and that in certain places in the world the water is considered hazardous

        Nobody cares about old history where people can only drink sewage; also, bottled water is way cheaper if you are too poor to have safe drinking water you shouldn't be buying beer.

      Not now, certainly, but beer absolutely was used for health reasons back in antiquity.

    Is because the other 5% were false negatives.

    Chemical assays nowadays can detect near-single-molecule quantities of stuff. The problem is that we don’t really understand what concentration of these molecules are bad for you (yet).

    There’s radioactivity in literally every object on the planet. Lead and Arsenic contamination is detectable in every object you put in your mouth. Same goes for PFAS.
    • by methano ( 519830 )
      Really! This is the question. There's detectable levels and there's toxic levels. There's acute toxic levels and there's chronic toxic levels. How many orders of magnitude are these things separated. I grow weary of the alarmist crap that we're constantly bombarded with because journalist can't, in general, do math. We need numbers to be informed.

      Oh, I'm sorry. I guess 95% of bears is a number after all.

      Actual beer breweries test their beer with mass spectrometers and gas chromatographs. They systematically detect arsenic, because arsenic is a persistent component in barley, and it's a natural part of the plant, and there's nothing you can do about, and nothing you need to do about it...the levels are just insignificant to health, but are easy to detect with lab equipment. The ethanol component of the beer is far and away the most unhealthy part of it.

      So you could just as easily write an article "aresenic found in 100 of of 100 beers tested". And it would be so much fake news. So when I see an article saying they "detected" some kind of PFAS chemicals in beer, with no information about how much they detected or what kind of PFAS molecules or what amount of those chemicals are dangerous acutely or chronically...it's just as much fake news.

      I actually care about PFAS pollution, that's why we need the media to do better so we can assess it seriously. When they publish slop, everyone just learns to ignore the issue.
      • Presumably you could grow barley in arsenic-free soil. This is probably prohibitively expensive, but it's the kind of thing slashdotters would insist on.

        The word you need to hear is "bioaccumulation". The only material I am familiar where that word is applicable is: Lead. Even tiny amounts of lead are bad because your body can not get rid of it. Ever. If PFAS doesn't bioaccumulate, small amounts carry no worries. If it does biolaccumulate... we are in deep shit.

      Actually we do. Many PFAS compounds have been studied and most of them have been found to be harmful at levels above a few 10s of Parts-Per-Trillion in animal testing. This is what really started this entire thing in the first place - the recognition that there is a harmful level, and the general levels in many people is above this level.

        Nevermind the fact that the industry itself knew it was a problem decades ago. And they covered it up when regulators started sniffing around by modifying the chemicals to

  • What about the plastic liners in the beer cans that remain in contact with an organic solvent?
    • They probably have tested beer bottles as well or that'd be some really dumb article.
      • According to the article, they identified the cans as a possible source. So, no testing. They also identified cleaning agents as a possible source. No testing. They identified the raw ingredients outside of water as a possible source. No testing. Read the Limitations section. We found PFAs in beer, source unknown, but here's some speculation.
  • Perhaps replacing all the copper pipes with plastic wasn't the best idea we had ?
    • PEX has no fluorine, not even chlorine.

      • Correct, but PEX pipes do contain and leach MTBE (the controversial octane enhancer that used to be used in gasoline), ETBE (its slightly larger cousin), toluene, phthalate esters, and other chemicals. Of course, sticking with copper isn't 100% safe either because copper pipe leach copper, at least until they're well-coated with a layer of minerals (assuming hard non-acidic water; if your water is soft and acidic the plumbing leaches copper continuously and you get holes in the pipes)

        Pick your poison.

  • Beer brewed with municipal water that nobody drinks because it is so bad that all over the country people drink water from the now famous 'water-cooler', results in bad beer?

    Who would have thought.

  • What percentage of "American Beer" actually contains beer?

  • The term would imply that no matter what the source or supply, it would transfer into the finished product. Why are we suddenly singleing out and worried about beer.
  • Nearly all so called "clean" water across the planet is polluted with microplastics, given that water is vital ingredient in the beer making process this is not in the slightest bit unexpected. Once again a study from the department of the fucking obvious.

    I slogged through the paper (it's surprisingly readable) to section 4.3. That's the money section, where they talk about not what they can detect but whether the measured levels exceed health recommendations. There aren't recommendations for beer so they use the levels for water, which seems pretty reasonable to me.

    Of the 23 beers they tested, three exceeded the recommended level. And bear in mind, they picked beers which are brewed in areas known to have high PFASs in the local water so this was a worst-case measurement. This all seems much less scary than the headline.

    The next question I would ask is how do the health consequences of the PFASs compare to the consequences of ethanol? I'm pretty sure nothing good comes from the actual alcohol and expect that's the bigger threat.

    • The next question I would ask is how do the health consequences of the PFASs compare to the consequences of ethanol?

      While nothing good comes from ethanol, it is a substance that works its way out of the body. PFAS on the other hand bioaccumulates. The only known way to get it out of the body is by bleeding (literally blood doners can lower their PFAS level). Ethanol consumption is bad, but it's also something that doesn't cause lasting damage in smaller doses, unlike smoking for which there's no safe dosage.

  • ...won't be easy to undo.

  • The level found is largely irrelevant.

    You might not want it, and as policy it's great to get them out of the supply chain; but at these concentrations a lifetime of heavy drinking will increase your risk of dying by bicycle (as a pedestrian) higher than the increase risk from this source.

  • How is this unexpected. If PFAS have been found in surface water, ground water, and drinking water, what the heck else do people think beer is made from? Of course beer will contain PFAS, it's not like the fermentation process breaks it down.

Truth is free, but information costs.
