Air quality remains very poor

Friday, 19 October 2018 | Staff Reporter | NEW DELHI

The air quality of the national Capital remained “very poor” for the second consecutive day for this season with several areas in the national Capital nearing “severe” levels of pollution, according to the authorities.

The overall Air Quality Index (AQI) of Delhi was recorded at 315, same as Wednesday, according to the Centre-run System of Air Quality Forecasting and Research (SAFAR). The Particulate Matter 2.5 (presence in the air of particles with a diameter of less than 2.5 micrometers) touched a new high at 158, even as the authorities said it could increase further.  The PM 2.5, also called “fine particulates,” is a more serious health concern than PM10.

An AQI between 0 and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor” and 401 and 500 “severe”.

 A senior Central pollution Control Board (CPCB) official said the situation is being monitored and depending upon the quality more stringent measures like increase of parking fees and complete ban on construction activities would be imposed.

“We are hoping that with a slight improvement in meteorological conditions, the air quality would improve. But if it doesn’t, we would impose stringent measures,” he said.

On Thursday, Anand Vihar recorded an AQI of 315, Dwarka Sector 8 369, ITO 256, Jahangirpuri 337 and Rohini 368, according to the Central Pollution Control Board (CPCB).

The PM10 level (presence in the air of particles with a diameter of less than 10 micrometres) in Delhi stood at 297 and the PM 2.5 level was recorded at 140, according to the CPCB data.
