Delhi world's most polluted major city on eve of Diwali, Swiss group says
BENGALURU (Reuters) -- Delhi was the world's most polluted major city on Saturday morning, according to Swiss ​group IQAir's live ranking, as the Indian ‌capital faced severe pollution forecasts a day before Diwali, the Hindu festival of lights.
 
India has ordered schools in and ​around Delhi to offer online classes, and ​encouraged people to work from home ahead of ⁠Diwali on Sunday, which is usually marked ​by the widespread use of firecrackers that further worsen ​the air quality.
 
IQAir ranked Delhi first among the world's major cities at 10:35 a.m. (0505 GMT), with a US air quality ​index reading of 581, double that of ​Lahore in neighbouring Pakistan, at 285.
 
IQAir's reading, based on concentrations ‌of ⁠air pollutants, is not directly comparable to India's official index, which uses a different scale and methodology.
 
India's Central Pollution Control Board put Delhi's air quality ​index at ​363 at ⁠10 a.m., in the "very poor" category. Friday's air quality in Delhi was the ​worst pre-Diwali air in eight years, local ​media ⁠said, citing official data.
 
Pollution is an annual problem in many parts of northern India from the onset ⁠of ​winter as cold, heavy air ​traps vehicle emissions, construction dust and smoke from crop-waste burning.
