California Votes To Ban Microbeads

New submitter Kristine Lofgren writes: The California Assembly just passed a vote to ban toxic microbeads, the tiny flecks found in toothpastes and exfoliants. Microbeads cause a range of problems, from clogging waterways to getting stuck in gums. The ban would be the strictest of its kind in the nation. As the article notes, the California Senate would need to pass a bill as well, for this ban to take effect, and if that happens, the resulting prohibition will come into place in 2020. From the article: Last year, Illinois became the first state in the U.S. to pass a ban on the usage of microbeads in cosmetics, approving a law that will go into effect in 2018, and earlier this year two congressmen introduced a bipartisan bill to outlaw the use of microbeads nationwide. And for exceptionally good reason; the beads, which serve as exfoliants and colorants are a massive source of water pollution, with scientists estimating that 471 million plastic microbeads are released into San Francisco Bay alone every single day.

    471 million potatos is a lot of potatos.
    471 million .2mm bits of plastic is enough to cover in plastic all of the living rooms in California.
    Wait - no - one living room. Or about a dinner-plates worth a day.

    This isn't the first time that I've seen mention of this. If I'm remembering previous articles correctly, these beads are ending up being consumed by very small sea creatures, who cannot process them, who then are eaten by bigger sea creatures, who also cannot process them, etc, until they build up in large concentrations toward the top of the foodchain to poison those alpha predators. There's concern for humans that eat those largest animals too.

    Honestly I'm surprised that they were legal in the first place, but if there wasn't an explicit law against them then I guess the companies that have manufactured and used them were free to do so regardless of any perceived morality on the matter.

    It gets stuck in some species guts, and some smaller invertebrates guts dramatically reducing their ability to feed.
    It is an actual problem.
    Another major issue is the beads attract pollutants onto their surfaces. These are then efficiently transferred into whatever ingests them.

    There is very little reason to be using plastic microbeads, rather than - for example - wood.

    It's a little more than that. Studies have shown toxic pollutants bind to microbeads. Other studies have shown fish are eating the microbeads and absorbing the toxins. Humans eat fish. Microbeads are poisoning our food supply, and a number of governments are sponsoring studies to learn more about their impact.

      They're small enough that they don't steal to the top in any meaningful time, and aren't attracted to any floculants. There is currently no good approach to treating them in sewage beyond hoping UV will break them down. Hope is not a plan.

      Did I suggest that or are you a halfwit?

      I have been pretty clear from my FIRST post that I don't really care.

      Ban the fucking beads. I don't care.

      Did that process in your little brain? How many times do I have to say that for you morons to grasp that?

      Okay, so you righteous chewing out concluded, my point is that if these beads are making it through and they have a lower density... why are they getting through the settling tanks? Am saying "if this is a problem, we probably have OTHER problems that we don't even know about." Thus shouldn't we just make the treatment process better? Not because of these beads... because again... ban them... I do not care... but rather this should be a wake up call that the treatment facilities need to be improved.

      Do you understand NOW? Or are you just that stupid? :)

      And I love that you suggested that I suggested that we use a medical centrifuge to clean sewage. I did no such thing. I was pointing out that they would absolutely sort by density. that is all. I also pointed out that maybe we could use an INDUSTRIAL centrifuge to further filter water.

      So run the water through the settling tanks to remove most of the particulates. Then power up a giant centrifuge to filter the product of the tanks.

      Maybe that isn't practical. I don't know how much energy that would gobble. But that was the closest I got to that idea. I at no point suggested we use tiny medical centrifuges to process municipal levels of sewage.

      You're an idiot. ;)

      BRANDIS FRIEDMAN: Microbeads end up in the waterways because water treatment plants simply can’t catch them. They’re too small.

      DAVID ST. PIERRE, Metropolitan Water Reclamation District of Greater Chicago: So small that even if there’s a sand filter in a plant, it doesn’t stop them from passing through the plant and into the water environment.

      BRANDIS FRIEDMAN: This is the third step in the water treatment process, where water is aerated, so lighter material rises to the top and heavier waste sinks to the bottom. But somewhere in the mix are still the microbeads, which make it through this entire multistep process and are sent out to the sanitary and ship canal along with fully treated water.

      Pretty much nothing that you all can do about that?

      DAVID ST. PIERRE: Not without a significant investment.

      BRANDIS FRIEDMAN: David St. Pierre is the executive director of the Metropolitan Water Reclamation District of Greater Chicago. He argues we should focus on prevention.

      DAVID ST. PIERRE: If we were to adapt our plants to deal with microbeads, it would be a very expensive process. If we deal with it on front end, we take care of it before it’s a problem by eliminating it as a pollutant source, very inexpensive way to deal with the problem.

    it's a little different. The microbeads bind to organic pollutants that were already in the water. Animals that eat the beads absorb the pollutants from every bead that passes through their system. The pollutants then move up the foodchain after leaving the beads behind in feces. Even small to medium sized fish are found to have 10-20 beads in their digestive tract at any given time.

    However, I am questioning the quality of your water treatment process if this is actually a problem.

    Have you ever heard of "Ocean Spray"? They grow lots and lots of cranberries. The crush the cranberries to make juice. They flush the dead cranberry skins down the drain. The local sewage treatment plant has terrible issues because the massive amount of cranberry residue screws with the chemical processes in the sewage treatment plant so that none of the sewage gets treated properly.

    The moral of the story is that sewage treatment plants are designed to handle the standard sewage that we all dump down the drain and they are not prepared to handle stuff that is not expected.

    Maybe YOU are willing to put up with a big increase in your local taxes to pay for the extra equipment needed?

    Your second point seems a tad weak as before being stuck on the bead, said pollutants are floating freely in the water the organisms large and small breath.

    Who says they are "floating freely in the water"? These beads will soak up oils that normally float on top of the water, and carry it down into the water to life that otherwise does not come in contact with those oils.

    The problem isn't necessarily the beads or whether or not they're toxic (though obviously, if they're made of a toxic material and being ingested that's a big problem).

    What's of concern is that it could potentially contribute, in a huge way, to a problem referred to as "plastic soup," a conglomeration of plastics from various sources, microbeads, regular trash being dumped at sea and so on. This isn't a small problem, either. The largest of "patches" of plastic debris could potentially be twice as big as the entire landmass of the U.S. as you can see here:

    https://en.wikipedia.org/wiki/...

    The exact size of the patch is hard to estimate for another reason, a lot of these plastics are _extremely_ difficult to see, particles that are essentially suspended just below the surface of the water. There are a lot of big, solid items in these patches that can be identified, but it's the former "soup" of plastic particles that's the real issue...they're hard to identify, they're hard to clean up and in the case of microbeads, they're hard to filter out of the water supply. Considering they offer little to no benefit in any of their commercial applications that I can see, I'm wondering why they haven't been banned already. I could easily see these cosmetic companies producing a fine-grained sand from any tropical beach and calling that "all natural microdermabrasion," it'd do less harm and people would probably buy the hell out of the stuff.
