Lower Air Pollution Means Longer Life 272

thefickler writes "A new study by the US National Institute of Environmental Health Sciences (NIEHS) has found a strong link between air quality and life expectancy. The researchers looked at air pollution, deaths and census data for 51 metropolitan areas between 1978 and 2001, and what they found was a direct correlation between improving air quality and extending life expectancy. People lived about 2.72 years longer over that time span and at least 15 percent of that increased life expectancy was from a decrease in air pollution."

      Yes, pollution concentration and contents changes over times and you need a methodology to keep track of these things. If common sense was a viable guide to life than we wouldn't need science.

        It's more than that. While "lower air pollution equals longer life" is a safe assumption at this point, "A decrease in air pollution amounting to 10 micrograms per cubic meter of of (sic) particulates in the air led to an additional .61 years of life" is not so obvious, nor is it even obvious how direct or significant the correlation would be.

          I don't have the time, but I'd like to see how they did the study.

          In the US at least, exposure to more air pollution is probably directly correlated in how car-centric a city in, and I could easily see the decrease in exercise being the driving force for most of the reduction in life expectancy.

          Comparing it worldwide gets even iffier -- lax air pollution standards probably correlates quite well with a poorer economy and lax standards in other areas.

      Without the study, there is no evidence to support the contention that there is a degree of correlation between 'heavy coughing' and longevity, or pollution and 'heavy coughing' or pollution and longevity.

    • Wasn't there something like 4000 deaths in a few weeks in Victorian-era England due to coal smoke and a bad inversion?

      You're probably thinking of "Great Smog of London" [wikipedia.org] which was actually in 1952! Not all that long ago really.
      4000 people were killed during the smog event itself, but it's thought that about twice that number died from it even after the smog cleared; a total of 12k deaths.
      This event definitely spurred on regulation of air quality in Britain.

      I think you're confusing the Victorian coal smoke problem with the killer smog during the 1950s. Though all those coal fires must have put out enough particulate to kill a lot of people, I doubt if there are any hard numbers.

      An ironic detail: London used to be famous for its fog. A good way to add atmosphere to movies and fiction. There's even a brand of raincoat (American, of course) called "London Fog". Alas, the London Fog is no more: it was caused by that same particulate that killed so many people.

      True, but how does causation ever get proven? Every day life doesn't exist in a lab and not all (or even most) variables can be controlled for. It's very much impossible to concretely prove causation within our populations for things that don't cause instantaneous death... Often times, the best we can hope for are very strong correlations and make a *reasonably* educated assumption.

        It doesn't get proven. That's the whole point of that objection.

    I really don't care about an extra 2-3 years of nursing home hell where I'm fed through a tube and can't remember my own name. I'm sure I'll feel differently when I'm closer to that time of my life, but right now it's just not on my list of priorities to extend that part of my life which is certain not to be the best.

    What I do care about is QUALITY of life. I bet the last few years those people who live in a more polutted place spend are not happy healthy years. Show me stats on the last 10 years of life and how sick people were.

    • Alright then, but do you really think spending the last few years of your life choking to death on air pollution clogged lungs is somehow 'better'?

      Seriously. 'Better air quality' isn't some fairytail greenpeace myth thing. There are and can be demonstrable differences in the 'quality' of the air we breathe, and, according to this study, the better the air a person breathes, the longer they live.

      Now, they're not saying that extra lifespan is spent in 'nursing home hell', but do you really want to die /sooner

      but clean air isn't giving you 2-3 extra years in a nursing home.
      With better air quality, you should stay healthier longer, and will be moving in to that nursing home 2-3 years later.

      Cleaner air could give you 2-3 more good years.

      It's more complicated than that.

      What if you get to have a nice estate in the country with clean air and healthy exercise, because you skim extra profits by polluting other people's air? You in effect ensure yourself decades of healthy living by taking a little bit of a bunch of other peoples' lives.

      I bring this up because viewing the atmosphere as a common cesspool hides the connection between the good quality of your life and the reduced length/quality of other peoples' lives. Yeah, you might say, it's too bad about the higher morbidity rate of people who don't have the gumption to pull themselves up by their bootstraps like I did, but it's not my problem. Except it should be your problem if what's really keeping you afloat isn't your bootstrap pulling, it's standing on somebody else's back.

      The important thing about capital, the thing that makes it really useful and powerful, is the way it has of flowing towards opportunity. But if you look at that trait carefully, you'll also see that the very same behavior means that it runs away from problems. So you take your profits from your goldmine and liquidate the company before the arsenic in the tailings starts leaking out. The entity legally responsible for the problems is now an empty shell.

      Any attempt to fix the incentive problem after the fact would undermine the positive functions of capitalism and corporations. Oh, I think there should be criminal prosecutions in such cases, don't get me wrong. But what you really have to do is to remove the ability to exploit the mobility of capital by creating problems and running away from them. People will bitch and moan that you're restricting capital's ability to build wealth, and they're right. But it doesn't restrict capital's real ability to generate value.

    Obviously the effect is statistical in nature and even if there was any benefit to an individual, it wouldn't be as effective as living in an area with low pollution. But still...?

      Filters can do nothing against other pollutants like, say, ozone or oxides of nitrogen. (Those "ionic" air "purifiers" actually very slightly increase the amount of ozone in the air.)
