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?
