Air Pollution’s Impact on Cognitve Intellengence: Study Results

On Monday, August 27th, the National Academy of Sciences published a study connecting air pollution with cognitive performance. Although it does not demonstrate cause and effect, I thought the connection was very interesting. The above link is from the BBC. Here's an excerpt from the BBC's article:

Over four years, the math and verbal skills of

Researchers believe the results have global relevance, with more than 80% of the world's urban population breathing unsafe levels of air pollution.

However, while establishing a link between pollution and lower test scores, the study did not prove cause and effect.

The study – which includes researchers from Beijing's Peking University and Yale University in the US – was based on measurements of sulphur dioxide, nitrogen dioxide and particulates smaller than 10 micrometres in diameter where participants lived. It is not clear how much each of these three pollutants is to blame.

Carbon monoxide, ozone and larger particulates were not included in the study….

…"We provide evidence that the effect of air pollution on verbal tests becomes more pronounced as people age, especially for men and the less educated," the study published on Monday in the Proceedings of the National Academy of Sciences said.

I'm so much more aware of air pollution now that my asthma diagnosis changed earlier this summer to persistent. 

Do you think studies like this will help people without asthma understand how important air quality is?

    Brenda, I saw that article on my news feed, and I was hoping that people WOULD understand that air quality affects us all. 

    I think it's really important for all of us to be able to breathe. I was in China some years ago, and the air quality was atrocious. There were nights when we would walk outside of restaurants, and strange metallic smell would hang in the air. Skyscrapers would disappear into muddy mists of dust. When we would mention it to locals, they would shrug and say that there was nothing that could be done.

    That's why I'm really glad that AAFA is part of the .

    I would hope it would help people understand but have come to realize if people don't life it, they don't understand it.
