Alarming air quality scene in India

But for the first three weeks of this year, New Delhi’s average daily peak reading of fine particulate matter from Punjabi Bagh, a monitor whose readings are often below those of other city and independent monitors, was 473, more than twice as high as the average of 227 in Beijing. By the time pollution breached 500 in Beijing for the first time on the night of Jan 15, Delhi had already had eight such days. Indeed, only once in three weeks did New Delhi’s daily peak value of fine particles fall below 300, a level more than 12 times the exposure limit recommended by the World Health Organization.

“It’s always puzzled me that the focus is always on China and not India,” said Dr Angel Hsu, director of the environmental performance measurement program at the Yale Center for Environmental Law and Policy. “China has realized that it can’t hide behind its usual opacity, whereas India gets no pressure to release better data. So there simply isn’t good public data on India like there is for China.”

Experts have long known that India’s air is among the worst in the world. A recent analysis by Yale researchers found that seven of the 10 countries with the worst air pollution exposures are in South Asia. And evidence is mounting that Indians pay a higher price for air pollution than almost anyone. A recent study showed that Indians have the world’s weakest lungs, with far less capacity than Chinese lungs. Researchers are beginning to suspect that India’s unusual mix of polluted air, poor sanitation and contaminated water may make the country among the most dangerous in the world for lungs.

- - - - Indians’ relatively poor lung function has long been recognized, but researchers assumed for years that the difference was genetic. Then a 2010 study found that the children of Indian immigrants who were born and raised in the United States had far better lung function than those born and raised in India. “It’s not genetics; it’s mostly the environment,” said Dr. MyLinh Duong, an assistant professor of respirology at McMaster University in Hamilton, Ontario.

In a study published in October, Dr. Duong compared lung tests taken in 38,517 healthy nonsmokers from 17 countries who were matched by height, age and sex. Indians’ lung function was by far the lowest among those tested.

Never realised it was this bad. And, Bangalore can't be much better either. So, the answer lies in reversing the process; not abandoning the cities. And, we all owe it to the future generations.
