Emergency declared as smog chokes parts of India and Pakistan
By Yan Zhuang
NEW DELHI – Authorities in New Delhi closed schools and urged people to stay indoors as toxic smog, which has plagued neighbouring Pakistan for weeks, choked India’s capital in what officials called a medical emergency.
New Delhi and the surrounding metropolitan area, home to about 55 million people, had the world’s worst air pollution Monday (18), according to IQAir, a Swiss company that measures air quality. The reading on its index rose to over 1,600.
Anything above 301 on that index is considered hazardous, potentially leading to severe eye and throat irritation and serious heart and lung conditions. The US Environmental Protection Agency essentially considers anything beyond 500 to be off the charts.
“All of North India has been plunged into a medical emergency,” Atishi Marlena, the chief minister of Delhi, said Monday, adding that many cities were “reeling under severe levels of pollution”.
The same pollution has enveloped parts of Pakistan, where authorities have banned most outdoor events, cancelled most classes and told some workers to stay home.
Parts of northern India and Pakistan experience severe air pollution each year in the late fall, as farmers burn straw left over from their rice harvests to make room for new planting. But even for a region with cities that regularly top the list of the world’s most polluted, the air quality readings this year have been dire.
For weeks, Punjab, the largest province of Pakistan, has experienced some of the worst air pollution on record, surpassing 1,000 on IQAir’s index for the first time earlier this month.
Punjab, which borders India, began closing some schools two weeks ago. It enacted more measures in the following days and asked workers to stay home last week. It has also banned outdoor events and most construction activity, and it has closed parks, playgrounds and monuments.
Authorities there declared a health emergency Friday, warning of an “unprecedented rise” in the number of patients with lung and respiratory diseases, allergies and eye and throat irritation.
Delhi announced similar measures last week as its air quality, which had been poor for weeks, deteriorated further. The capital region’s Commission for Air Quality Management said Thursday that all primary schools would close and shift to online learning and that some construction work that generates dust and pollution would be halted.
On Sunday (17), more measures were introduced as the pollution worsened. Some secondary school classes moved online, while diesel trucks were banned from entering Delhi. Authorities have not indicated how long the measures will last.
Many scientists have said that farmers burning rice stubble in Punjab are largely responsible for the pollution, although Pakistani officials have also pointed at India, where farmers also burn crops. Falling temperatures also appear to play a part, with cooler air trapping pollutants and preventing them from dispersing over the Himalayas.
