NEW DELHI (Reuters) - Air pollution in New Delhi and surrounding towns reached the worst levels so far this year on Sunday, with authorities in the world’s most polluted capital city having already declared a public health emergency and ordered the closure of schools.
The air quality index, measuring levels of PM 2.5, tiny particulate matter in the air, deteriorated to above 900, way over the 500-level that qualifies as “severe-plus”.
Aside from the harm it was doing to the lungs of some 40 million people living in the capital region, the smog was so bad more than 30 flights were diverted from Delhi airport due to poor visibility.
Roads looked deserted as large numbers of people stayed home, rather than expose themselves to the noxious atmosphere outside.
“Pollution has reached unbearable levels across north India,” Arvind Kejriwal, Delhi’s chief minister said in a message on Twitter.
The government environment monitoring agency SAFAR warned that no relief was expected for the next one to two days, as humidity resulting from unexpected light rains overnight had exacerbated pollution, already driven by higher the seasonal crop stubble burning by farmers in the surrounding states.
“Wind speed is picking up and it could take 24 to 48 hours before the pollution level reduces to a level of around 500,” Mahesh Palawat, vice president of Skymet, a private weather forecasting agency, said.
Anything above 400 on the AQI poses a risk for people with respiratory illness and can also affect even those with healthy lungs.
Doctors were reporting a spike in patients with respiratory related issues, according to Sachin Taparia, head of Local Circles, a Delhi-based private consultancy that conducts surveys on government policies and programs.
“Delhi has turned into a gas chamber as the pollution levels hit the ‘severe+’ category,” Taparia said.
