Air pollution linked to huge reduction in intelligence

Air pollution has a huge negative effect on intelligence, according to a study by the National Academy of Sciences

The research is one of the first studies to focus on the links between air pollution and cognition in older people. It was done by scientists at Peking and Yale Universities, and published in Proceedings of the National Academy of Sciences. In particular, it found that long-term exposure to air pollution may worsen cognitive performance (intelligence). In other words, air pollution is making you dumber.

The study included over 25,000 people across 162 randomly chosen counties in China. It included daily readings of three atmospheric pollutants: sulfur dioxide, nitrogen dioxide and particulate matter smaller than 10 micrometers (PM10).

The research found that cumulative exposure to air pollution worsen cognitive performance in both verbal and math tests. It found that as people age, the negative effect becomes particularly pronounced, especially for men. Those chronically exposed to air pollution through working outdoor, manual jobs were logically even more affected.

The findings of this research is particularly worrisome for the elderly, as they are already in danger of cognitive problems, such as mild memory loss and attention difficulty. Dementia is the fear of many senior citizens, and air pollution may be a contributing factor for developing this devastating disorder.
