New Delhi: The air quality in the national capital remained in ‘very poor’ category for the second consecutive day on Sunday. The authorities believe that it may further deteriorate in the next couple of days.
As per the data from the Central Pollution Control Board (CPCB), the overall Air Quality Index (AQI) of Delhi was recorded at 301 on Sunday, which falls in the ‘very poor’ category. Anand Vihar, Mundaka, Narela, Dwarka Sector 8, Nehru Nagar and Rohini all showed ‘very poor’ air quality and are inching towards severe pollution levels, it said.
Meanwhile, Saturday witnessed the worst air quality of this season which was recorded at AQI 324. The city remained engulfed in a haze all through the day.
The PM2.5 (presence of particles in air with a diameter of less than 2.5 micrometres) touched a new high at 167. The PM 2.5, also called “fine particulates”, can be a matter of more serious health concern than PM10. On the other hand, the PM10 level (presence of particles in the air with a diameter of less than 10 micrometres) in Delhi stood at 293, according to the data from the Centre-run System of Air Quality Forecasting and Research (SAFAR).
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”.
Earlier on Friday, the Supreme Court-appointed Environment Protection Control Authority (EPCA) held a meeting with state governments and Delhi government officials to discuss the pollution situation in the national capital.
An EPCA member said stock of the situation was taken and it was decided that special attention would be given to vulnerable hotspots where ‘poor’ or ‘very poor’ air quality is observed.
Deteriorating air quality is a result of number of factors, including vehicular pollution, construction activities and meteorological factors like direction of wind which is now flowing from the stubble burning areas, a CPCB official said.
Delhi Chief Minister Arvind Kejriwal had on Friday warned that the city would become a “gas chamber soon” as the Centre, Punjab and Haryana governments did “absolutely nothing” for farmers involved in stubble burning. “V sad that Central, Punjab and Haryana Govts did absolutely nothing for the farmers. As a result, the farmers will suffer on one hand and Delhi will become a gas chamber soon (sic),” he tweeted.
