Air Pollution Causes 'Huge' Reduction in Intelligence, Study Reveals (theguardian.com) 269

Air pollution causes a "huge" reduction in intelligence, according to new research, indicating that the damage to society of toxic air is far deeper than the well-known impacts on physical health. From a report: The research was conducted in China but is relevant across the world, with 95% of the global population breathing unsafe air. It found that high pollution levels led to significant drops in test scores in language and arithmetic, with the average impact equivalent to having lost a year of the person's education. "Polluted air can cause everyone to reduce their level of education by one year, which is huge," said Xi Chen at Yale School of Public Health in the US, a member of the research team. "But we know the effect is worse for the elderly, especially those over 64, and for men, and for those with low education. If we calculate [the loss] for those, it may be a few years of education."

The damage in intelligence was worst for those over 64 years old, with serious consequences, said Chen: "We usually make the most critical financial decisions in old age." Rebecca Daniels, from the UK public health charity Medact, said: "This report's findings are extremely worrying." [...] The new work, published in the journal Proceedings of the National Academy of Sciences, analysed language and arithmetic tests conducted as part of the China Family Panel Studies on 20,000 people across the nation between 2010 and 2014. The scientists compared the test results with records of nitrogen dioxide and sulphur dioxide pollution.

    It's totally anecdotal, but I lived in Vancouver, BC for 3yrs, and I felt like I had a fog in my head there. The air there isn't terrible, but living in the middle of this bustling city definitely had lower air quality. Moved back to Victoria, BC a year ago (where I came from, and a quiet, less-populated area by the ocean), and felt that go away pretty quick, and haven't felt like that since.

    Again, may just be my imagination, but seems plausible.

      Carbon monoxide substitutes for oxygen in your biologic system, substitutes chemically but not functionally and takes considerable time to remove from your blood stream, it has to diffuse out. The more you have the quicker it leaves and the less it becomes the slower the removal, numbers between it and excess oxygen (so snort a bunch of oxy before bed time). Carbon monoxide make brain not work good https://en.wikipedia.org/wiki/... [wikipedia.org]. Stop burning shit, especially that really old fossilised shit (heh heh).

      Now for shits and giggles, add in lead (you need it for the real cra cra, that gun nut cra cra) as well as a range of endocrine disrupting chemicals, radioactive elements breaking down into Radon, 'ohh my', nation wide fracking and things get real interesting.

        90-10 Bismuth-tin bullets are a good lead replacement for hunters who don't like poisoning themselves. They fragment rather than deform because they are brittle, but this means no lead dropped in forests and no lead in your venison. It seems a fair trade.

      I recently moved from a major city to the outskirts of a small city. I also found that having nature around you instead of concrete also has a huge uplifting affect on the soul. People are a lot friendlier where I moved to. Maybe it is a greater abundance of oxygen, I did not consider that. People are not meant to be crammed into cities.

        Unfortunately for many of this this is not an option: the extra pollen due to AGW [vox.com] is just as bad for those of us with allergies... even after the 2-year course of weekly shots.

        (And FWIW it may not be as toxic, but pollen accounts for some PM10 particulate matter, so it would be interesting to see this study enhanced to differentiate between pollen and more directly man-made pollution.)

        My experience doesn't line up. I've lived in large Australian and Asian cities, and in small Australian towns. One town in particular was full of ignorant people and the average intelligence was definitely lower than in the cities. People in country towns are less welcoming, worse gossips, more likely to hold grudges. People in cities are exposed to more variety of people and ideas, and more open-minded and educated on the whole.

      I used to get fog head from sitting on the top deck of a double-decker bus when one set of wheels went over a speed bump and the other set didn't. That led to the bus shaking sideways three or four times until the suspension damped things down. I had to immobilize my head by hunching my shoulders up until the bus passed the speed bumps in order to avoid this.

      Most of the kind of pollution studied here (particulates) no longer comes out of the power plants in Western world, and hasn't been coming from power plants across Europe and US for something around two decades.

      Primary sources of it around here is automotive. Specifically combination of exhaust on mainly older diesel vehicles combined with street dust being pulled out of road surface by act of driving over it over and over again. Notably, not even Scandinavia is safe from this, in that we get our worst part

        Correct. And air pollution is fairly low both in the US and Europe, in particular outside city centers.

        Overall, in Europe and North America, this is mostly about city centres on days when it isn't windy.

Air pollution was a huge concern for California until we formed the CARB and set meaningful standards. And given the prevailing winds, guess where most of California's pollution winds up? Yeah, in the rest of the country. And Canada, of course. They've been sucking our smoke for weeks now.

            I assume California is perfectly free to accomplish those objectives via other, local regulations. For example, cities like LA could limit the city center to low emissions vehicles or sell special city access stickers. But setting state-wide limits on what cars can be sold in California because LA has bad air quality is irrational.

  • burn more coal!

  • It should not be difficult to fathom that much of the pollution in most every part of the world is from burning coal and liquid petroleum fuels. This is primarily from generating electricity and transportation. People don't burn these fuels because they want pollution, they burn them because they are cheap and convenient. To get cleaner air we need energy that is not just clean but also cheap and convenient. How shall we do this?

    To get an engineering plan start with the cheapest electricity.
    https://en.wikipedia.org/wiki/... [wikipedia.org]
    Geothermal comes out on top. Natural gas is second. What's the next three, tossing out dirty coal? Hydro, nuclear, and wind.

    While not a pollutant I'll take a short diversion and look at CO2 output of the different energy sources for electricity.
    https://en.wikipedia.org/wiki/... [wikipedia.org]
    The best three on that list is hydro, nuclear, and wind. Geothermal and solar make a good show as well. Natural gas isn't great but it is far better than coal.

    Let's look at the energy sources with the best energy return on investment, because long term this will reflect on the cost.

    If we toss out dirty oil and coal we again get the same top three, hydro, nuclear, and wind. Geothermal and natural gas make a good show as well.

    Let's look at the safest energy sources, because even if we clean the air for health reasons it doesn't help if people are dead.
    https://www.forbes.com/sites/j... [forbes.com]
    Hydro, nuclear, and wind top the list, solar certainly does well, and there's a wide margin to the rest. Geothermal is not on the list for some reason. Natural gas isn't great but better than coal and biomass fuel.

    By my estimation we need to use hydro, nuclear, and wind for electricity. Until I can see more about geothermal I can't recommend it. Solar simply costs too much, is not very convenient/reliable, and isn't all that great on safety, so I can't recommend it unless all others are unavailable. Wind and nuclear need a little help to load follow and hydro works well for this. If there isn't enough hydro around then the obvious choice is natural gas.

    When it comes to transportation we should electrify as much land transport as we can, cars and trains mostly. What do we do about vehicles where electricity is not practical? Mr. Pickens has a plan, natural gas.
    http://pickensplan.com/the-pla... [pickensplan.com]

    Pickens admits that that natural gas is a bridge fuel. A bridge to what? Maybe synthesized fuel from hydro, nuclear, and wind, that's my guess. Natural gas burns far cleaner than gasoline, diesel, and marine fuel oil. Natural gas is a proven technology, cheap, plentiful, and can be adopted fairly quickly. At least adopted quickly for most transportation on land and sea. For air transportation we'll need to continue with kerosene until we find something better.

    Natural gas is as convenient as electricity and gasoline combined for personal cars. People can fill up at a filling station in minutes like gasoline, and at home if you have natural gas service for heating and cooking. Maybe the best could be from a natural gas/electric hybrid.

    At sea we can adopt more nuclear, beyond just warships. Perhaps even resurrect the windjammers, sailing ships built in the last days of sail using steel hulls and other modern materials.

    I keep seeing articles on the problems of dirty, CO2 emitting, dangerous, and expensive energy. Let's talk solutions. Here's my solution... Wind, hydro, and nuclear with a little natural gas.
