On Thursday, doctors strongly recommended wearing masks and staying indoors as the air quality in the National Capital Region (NCR) suddenly deteriorated to severe levels due to a dust storm that began on Wednesday and is likely to persist till Friday.

"Implementation of action plans and the need to control air pollution is a debate largely reserved for the winters, during emergency-like situations most measures tend to be in place-for examp le closing of schools", said Aishwarya Sudhir, an independent researcher, told IndiaSpend.

A thick layer of dust has settled over the Delhi and National Capital Region (NCR).
The CPCB said pollution this summer is very different from past year.
The wind direction in Delhi since Sunday has changed to West and North West and then since Tuesday to West and South West, due to which hot air, along with dust from Rajasthan has started moving into Delhi. In November previous year, both PM2.5 and PM10 had spiked which was posing a serious health hazard.
High particulate matter (PM) 10 levels in the capital are due to high wind speeds which have brought dust particles from neighbouring Rajasthan.
