New Delhi air pollution

The air pollution level in the Indian capital region Delhi on Thursday became severe, officials said.

According to the Central Pollution Control Board (CPCB), the overall air quality index (AQI) remained in the severe category at 442.

The air quality was severe and prominent pollutants were PM 2.5 and PM 10, said the CPCB.

The information has been received from monitoring stations set up across Delhi.

Experts said PM 2.5 were fine particles that were 2.5 microns or less in diameter and can travel deep into the respiratory tract, reaching the lungs and entering the bloodstream.

Health officials have advised people, especially those with respiratory illness, in Delhi to minimise outdoor exposure until the improvement in air quality.

Doctors said severe air quality affects healthy people and seriously impacts those with existing pulmonary diseases.

Air pollution continues to worsen in Delhi and it gets aggravated during winter months.
