Is air pollution making us dumb?

In India and China improving the quality of air by 15-20 percent increase the chances of a 60 year old elderly people to live to 85 years.

The study, led by engineering professor Joshua Apte, was the first of its kind where researchers looked at data on air pollution and lifespan together.

Above all, air pollution reduces liveablity of different cities, including the capital already ranked among the world's worst liveable cities for different reasons by different global agencies.

It is well known that air pollution has negative effects on human health.

Cars fill streets with exhaust and tiny particles.

PM2.5 is released from tailpipes of vehicles, coal-fired power plants, and agriculture and industrial emissions.

All this air pollution - smog, soot, and ozone - does more than choke the lungs of everyone breathing it in.

We already knew that being exposed to bad air cuts lives short and is bad for kids, harming their developing bodies and brains, according to the study's authors. " This decline in verbal scores was especially notable in older, less educated men, which researchers say could have effects on the economy as well".

"What's new in this paper is the focus on the China scenario and the fact that it's a very detailed study compared to many other ones", he said.

The researchers believe that the study has global relevance, because 80% of the world's population breathe polluted air.

An increase in pollution level over seven days led to a drop in verbal test scores by 0.278 points. They matched those results with pollution conditions at the time of each test, and found sobering results. This cumulative effect was significant.

The study found that language abilities faced a greater impairment than math abilities, and that men were more at risk of experiencing these impacts than women.

Air pollution is causing a "huge" reduction in our intelligence, according to a new study. China has a first-rate pollution be concerned that has resulted in crimson indicators in dozens of cities, and the govt.is actively attempting to fashion out the be concerned.

However, cutting the annual mean concentration of particulate matter across China to meet environmental standards (50 μg/m) would move people from the median to the 63rd percentile in verbal test scores, and the 58th percentile in maths test scores.

The decline in verbal scores was more marked among males and became more pronounced with age, the study showed. Nearly all the cities in low- and middle-income countries with more than 1,00,000 residents fail to meet World Health Organization air quality guidelines.
