Delhi continues to grapple with a severe air pollution crisis, with the Air Quality Index (AQI) stubbornly remaining in the 'very poor' category across numerous localities. Data from monitoring agencies on Thursday, December 5, 2024, painted a grim picture, showing readings consistently above the 300 mark in several key areas, compelling authorities to keep the stringent Graded Response Action Plan (GRAP) Stage III measures in effect.
Widespread 'Very Poor' Air Grips the Capital
The Central Pollution Control Board (CPCB) recorded alarming air quality levels at multiple stations. The AQI at Anand Vihar was registered at a concerning 367, while the monitoring station at IGI Airport (T3) reported a value of 341. Other severely affected areas included Punjabi Bagh (AQI 356) and RK Puram (AQI 352). These readings fall squarely within the 'very poor' bracket (301-400), a category where prolonged exposure can lead to respiratory illness even in healthy individuals.
Meteorological conditions have played a significant role in trapping pollutants close to the ground. Calm winds and low temperatures have prevented the dispersion of harmful particulate matter (PM2.5 and PM10), creating a dense blanket of smog over the city. This persistent toxic haze has reduced visibility and raised serious public health concerns among residents and doctors alike.
GRAP Stage III Restrictions Remain Enforced
In response to the deteriorating air quality, the Commission for Air Quality Management (CAQM) has directed the continued implementation of GRAP Stage III curbs across the National Capital Region (NCR). This stage is invoked when the AQI is projected to cross the 400 mark into the 'severe' category. The restrictions include a ban on most construction and demolition activities, with exemptions only for essential projects.
Furthermore, the use of BS-III petrol and BS-IV diesel four-wheelers has been prohibited in Delhi and the adjoining districts of Gurugram, Faridabad, Ghaziabad, and Gautam Buddh Nagar. Authorities are conducting strict checks to ensure compliance with these rules, aiming to reduce vehicular emissions, a major contributor to the city's winter pollution.
Health Advisory and Public Response
Medical experts have issued urgent advisories, especially for vulnerable groups such as children, the elderly, and those with pre-existing heart or lung conditions. Doctors recommend minimizing outdoor activities, using N95 or N99 masks when going outside, and employing air purifiers indoors. The Delhi government has also reiterated its appeal for the use of public transport and carpooling to help reduce the collective emission load.
Residents across the city have reported a return of familiar symptoms like itchy throats, burning eyes, and breathing difficulties. The situation underscores the critical and recurring nature of Delhi's air pollution problem, which sees a sharp escalation every winter due to a combination of local emissions, stubble burning in neighboring states, and unfavorable weather patterns.
The enforcement of GRAP Stage III highlights the administration's efforts to control the crisis proactively. However, with AQI levels hovering just below the 'severe' threshold, the coming days remain crucial. Citizens are urged to stay informed through official channels and adhere to the pollution control guidelines for their own safety and to support broader mitigation efforts.
