Air pollution a leading cause in intelligence reduction
High rates of air pollution is a “huge” contributing factor to a broad reduction in intelligence, according to a new study released by the Yale School of Public Health (YSPH).
The study, conducted in China, found that high rates of air pollutants is correlated with significant drops in general test scores, and leads to an equivalent loss of a year of schooling in test results.
“Polluted air can cause everyone to reduce their level of education by one year, which is huge,” YSPH’s Xi Chen said.
“But we know the effect is worse for the elderly, especially those over 64, and for men, and for those with low education. If we calculate [the loss] for those, it may be a few years of education.”
The findings come after a recent study, published in Environmental Science & Technology Letters, confirmed that high levels of concentrated air pollution is shaving months of life expectancy.
