Microplastics Are Blowing In the Wind (scientificamerican.com) 118

An anonymous reader quotes a report from Scientific American: Scientists have detected tiny pieces of plastic falling out of the air like artificial dust. A first-of-its-kind study finds these particles have blown in on the wind from at least 100 kilometers away and likely much farther. This is a clear indication that atmospheric transport is yet another way plastic pollution is being distributed around the planet, even to remote areas. "And it suggests that this is a far bigger problem than we have currently thought about," says study co-author Deonie Allen, of the Ecole Nationale Superieure Agronomique de Toulouse (ENSAT).

The study, published Monday in Nature Geoscience, is one of only a handful that have attempted to measure how much plastic is falling from the atmosphere. It marks the first wave in what is likely to be a flood of such studies in the coming years, in an effort to fill in the picture of how microplastics move around the environment and how humans might be exposed to them. Allen and her colleagues knew microplastics had been found in rivers and sediments in the French Pyrenees, but no one had determined the sources. The bulk could not have come from local sources because of the small human population and limited industrial activity, so Allen was struck by a key question: "Why haven't we looked up?" That is what she and her colleagues did, taking advantage of atmospheric measuring equipment already in place in the Pyrenees and sampling over five months. They found plastic fibers, films and shards, all in a range of sizes. Most of the polymers that turned up in the samples were polystyrene, polyethylene and polypropylene, which are all common in single-use plastic products such as bags and foam food containers.
The study used computer models of atmospheric currents to attempt to backtrace the air that brought the microplastics in the Pyrenees, which is considered a pristine environment. It was clear that the relatively small towns and villages nearby "were unlikely to account for all of the plastic they detected, which suggests the ultimate sources are more distant," reports Scientific American.

        For manufacturing all the plastic crap that America consumes?

        For consuming their own share of plastic crap. Hint: the world doesn't consist of "people" in the West and "poor almost-humans who need our help" in the East.

        Anyway, plastic in the environment isn't a problem with making things out of plastic, but one of littering. Plastic waste doesn't magically escape from landfills.

      • No, they're burning plastic in Siberia. That's what he's vaguely alluding to. That's what is going to be discovered to be the primary cause of airborne plastic particles, some years from now after it's already too late to save the liver of everything left alive on the planet still that doesn't photosynthesize.

      Considering that the Pyrenees are located between France and Spain, both of which do have a plastic pollution problem, France and Spain seem much likelier sources for this particular case of microplastic pollution.

      But it would be nice to have a similar study done on microplastic pollution in the Himalaya, to compare to the Pyrenees.

      IMO (from my own travel and from talking to other people who noticed plastics pollution and travelled to the same places as me), this also is a cultural issue: People in France o

        On their respective coasts, their salt operations are already taking a hit, since microplastic was detected on all the expensive 'fleur de sel' products.
        People trying to avoid ingesting microplastics are now more likely to buy salt from deep in the Alps.

    Just a drop of water in an endless sea

    Now don't hang on
    Nothing lasts forever but the earth and sky
    It slips away
    And all your money won't another minute buy

    There will be life here after we are gone, along the way, people will be miserable.

      Glad to see I'm not the only person who started hearing this when he read the headline.

      • But did you hear Bob Dylan or Peter, Paul, and Mary? I know Dylan wrote it; but, when I think of the song, I think of the latter's recording of it.

          Peter, Paul, and Mary.

          I've heard the Dylan version before, but it's one of those songs where the cover's more remembered, like the Beatles' Twist and Shout instead of the Isley Brothers.

    I wonder if this sort of thing could be part of the collapse of insect populations in otherwise pristine environments. Vertebrates could probably clear most of this via mucus but arthropods aspirate differently.
