Disposable Face Masks Used During Covid Have Left Chemical Timebomb (theguardian.com) 159

alternative_right shares a report from The Guardian: It has been estimated that during the height of the coronavirus pandemic 129bn disposable face masks, mostly made from polypropylene and other plastics, were being used every month around the world. With no recycling stream, most ended up either in landfill or littered in streets, parks, beaches, waterways and rural areas, where they have now begun to degrade. Recent research has reported a significant presence of disposable face masks in both terrestrial and aquatic environments.

They left newly bought masks of several different kinds for 24 hours in flasks containing 150ml of purified water, then filtered the liquid through a membrane to see what came out. Every mask examined ... leached microplastics, but it was the FFP2 and FFP3 masks -- marketed as the gold-standard protection against the transmission of the virus -- that leached the most, releasing four to six times as many. And they made an even more worrying discovery.

Subsequent chemical analysis of the leachate found medical masks also released bisphenol B, an endocrine-disrupting chemical that acts like oestrogen when absorbed into the bodies of humans and animals. Taking into account the total amount of single-use face masks produced during the height of the pandemic, the researchers estimated they led to the release of 128-214kg of bisphenol B into the environment. [The researchers wrote that "approximately 128â"214 kg of BPB were released into the environment each day from those masks."]
The findings have been published in the journal Environmental Pollution.

      Vaccines have become the next abortion. They're the next issue the Republican party will offer its base in exchange for taking all their money and property.

      It's an absolute fact that Republican policies are bad for republicans, everyone else too.

      When you run the country like that and you are still nominally a democracy you have to offer your voters some reason to vote for you besides the economy. No matter how much propaganda you throw at them some, really most, are going to figure out that you're bad for the economy and for their livelihoods.

      The Republican party lives and dies by moral panics. Vaccination is now a moral panic. It's the one that's going to replace transphobia as it runs its course.

      That's really the problem. You always need a new moral panic. After the Republicans stole the supreme Court and filled it with corrupt sycophants they moved on to transphobia and rapid on set gender dysphoria but that's gradually running its course as people figure out that it's bullshit too and so now vaccination is the new moral panic.

      If you can figure out what the next one is going to be after vaccination is done then you have a extremely lucrative career as a Republican strategist ahead of you. Like as in you can make millions. All you have to do is serve up your fellow Americans chopped up on a plate.

    They compared a common type of covid face mask with surgical masks.

    Things they did not do that would make this real science, instead of click bait junk science:

    1) Compare with other common disposable items such as straws, plastic bags, plastic cups, etc. etc. Better yet, compare with the 6 major types of plastics (PET, HDPE, PVC, LDPE, PP, PS) Those are the numbers 1-6 on the recycle symbol used in the USA.

    2) Compare with a ton of random garbage from a legal land fill.

    So we have no idea if those numbers are high, normal, or low. All we were told is that modern materials give off chemicals with strange sounding names. Also, some of those chemicals are bad for you in sufficiently high quantities.

    That is not news. If you are shocked that modern materials give off chemicals, or that some of them are bad for you in high amounts, you should sit down and pour yourself a stiff drink before doing some googling about the topic.

    • That is not news. If you are shocked that materials give off chemicals, or that some of them are bad for you in high amounts, you should...

      FTFY.

      The pre-modern era had plenty of dangerous substances, too. Probably the deadliest was woodsmoke (way worse than microplastics in practice, though it doesn't accumulate the same way), but there were plenty of others. The modern era has added variety and subtlety, but that latter point is mostly just because we've gotten good at recognizing and mitigating the acute and/or obvious harms.

    The study worries about what the remains of face masks ending up in the environment and though a lot of indirect means, come back to us.

    Ok, but how does it compare to wearing masks. I am not just talking about the pandemic, I am thinking about medical and construction workers wearing respirators similar to COVID masks all day as they are working. All of the air they breath is filtered though these plastic fibers. Ok, these masks are presumably in good shape and not decomposing, but they are also ideally located to make everything that can go loose go right into our bodies, bisphenol and all.

    With that in mind, had masks been that bad, we should see an effect on people working with masks all day. Which, by the way, is likely to include those who conduct these kinds of experiments.

    IV bags and tubes also transmit microplastics...directly into the blood stream. But those same IV bags and tubes, save a whole lot of lives. So far, there hasn't been a single documented case of a person becoming sick or dying from microplastics from IV tubes.

    Doctors and nurses and dentists have been wearing them long before COVID because...they are effective at what they do. How many doctors--who have worn these masks for their entire careers--have died from inhalation of microplastics? If this were a common problem in the medical profession, it would have been a thing long ago.

    How about let's take a balanced approach to risk. Microplastics might (but it hasn't ben proven) cause some health problems for some people. But plastics are *known* to save a lot of lives through their use in healthcare, and are used in countless ways to improve patient health, and food safety. Plastic doesn't deserve to be demonized as it has been in recent times.

      Ha! No self-respecting researcher would ever attempt to document this, nor get funding to do so. It's like a drop in the bucket for exposures, and once the particle size is small enough they pass through cell membranes and (gasp!) into the bloodstream.

      Otherwise, thanks for the muddled lesson in harm reduction.

        It's not a lack of research, it's a lack of meaningful research.

            If microplastics are a health problem at all, it will be affecting far more than "one" person. It will be affecting thousands, millions of people. But despite researchers' many efforts to find a link between microplastics and health, none has yet been found. Yes, they've found that if you inject large amounts of microplastics directly into the bloodstream, it can cause strokes. But no study has found that "normal" environmental amounts of microplas

    • Remember when doctors were against handwashing before surgery because what you can't see can't hurt you? Are they blind to things like microplastics today?

      • The difference is, lack of handwashing, has been linked directly to mortality and disease spread. There is no such research linking microplastics to disease or mortality.

    • So far, there hasn't been a single documented case of a person becoming sick or dying from microplastics from IV tubes.

      There's not been a documented case of short term or causal linkage no. At no point has any study into microplastics said that they are immediately fatal in our blood. At best they have been directly linked to inflammation, and loosely linked to increase in cancer rates. With only a non-causal relationship established in the latter you'll never find a documented case of a person becoming sick or dying from microplastics in IV tubes, even if they do in fact get sick or die from microplastics in IV tubes.

    FFP2, FFP3, N95 are not "masks", they are respirators. And yes, they are the gold-standard because they actually work when fitted, worn, and handled properly. And they were probably a very, very tiny fraction of the trillions of mostly ineffective face coverings used.

    • FFP2, FFP3, N95 are not "masks", they are respirators.

      FFP2, FFP3, N95 are not respirators, they are standards. And if a device meeting the standard is strapped to your face, then it is a mask. There are also typically-shaped N95 masks without cartridges. They have short lifespans, but they do exist.

      • >"FFP2, FFP3, N95 are not respirators, they are standards."

        They are standards for respirators. Generally, respirators create a seal to the face and masks do not. I have worked with dozens of various types.

        >"if a device meeting the standard is strapped to your face, then it is a mask."

        Nobody in the medical field (at least in my experience in the USA) calls a procedure mask or surgical mask a "respirator" nor a respirator a "mask."
