Pollution Clogging Our Brains?

 Research, published online in the Proceedings of the National Academy of Sciences on Monday, found that long-term exposure to air pollution impeded people’s performance in both verbal and math tests.

Skills of thousands of Chinese nationals were studied for over four years. As the participants aged the scores deteriorated. The less educated and males suffered the most cognitive loss.


The study warned that the effects of pollution hold great economic and personal cost. Individuals are more susceptible to degenerative diseases such as Alzheimer’s and other forms of dementia.  The societal impact cannot be understated.

The study further insists that up to a year of education level can be reduced by a year due to pollution.

The study though very illuminating could not determine cause and effect due to lurking variables such as other unmeasured pollutants.

What does this mean for us?

This new study is just another indicator that we must be more cognizant of the pollution that we cause.  Learn how you personally can reduce pollution in your own life here.
