South Asia Toxic Air: Vehicle Exhaust, Farm Burning and In-Home Cooking

"Delhi consistently ranks as one of the most polluted cities on the planet, and 46 of the 50 most polluted cities are located in South Asia, a new report finds."

"In 2014, the World Health Organization reported that New Delhi was one of the most polluted cities in the world, with dangerous levels of fine particulate matter pollution, known as PM2.5. Ever since, New Delhi has been synonymous with hazardous air quality.

Over the last few years the air quality levels in one of the world’s fastest growing metropolises have ebbed and flowed, but for the most part New Delhi’s pollution levels remain higher than most cities across the world.

Now, the Swedish air quality monitoring company IQAir has released its annual World Air Quality report for the year 2021, again ranking New Delhi among the most polluted cities in the world and the most polluted capital city for a fourth consecutive year. IQAir also found that South Asia was the world’s most polluted region, where PM2.5 emissions from vehicle exhaust, commerce, the burning of stalks and other crop residue after harvest season and in-home cooking with solid fuels all combine to dangerously degrade air quality.

“You can barely see the leaves anymore, there’s a layer of dust that covers them all the time,” said Renu Singh, 39, a Ph.D student at Dr. B. R. Ambedkar University Delhi, describing the visible effects of air pollution in the city."
