Beijing`s US Embassy sent out warnings in mid-January, when a measure of harmful fine particulate matter known as PM2.5 rocketed above 500, in the upper reaches of the measurement scale, for the first time this year.

However, for the first three weeks of this year, New Delhi's average daily peak of fine particulate matter from Punjabi Bagh, a monitor whose readings are often lower than those of other cities and independent monitors, was 473, which was twice more than the average of 227 in Beijing, the Verge reported.
