For the second consecutive day, the national capital has been engulfed in a thick blanket of smog, with its air quality stubbornly remaining in the 'Very Poor' category. The overall Air Quality Index (AQI) for Delhi was recorded at 323 on Sunday, according to the latest data from monitoring agencies. This persistent pollution has led to hazy skies and reduced visibility across the city, raising significant public health concerns.
Detailed Air Quality Readings Across Delhi
The Central Pollution Control Board (CPCB) provided a granular look at the pollution levels in various parts of the city. The data, recorded at 4 pm, painted a grim picture. Anand Vihar recorded a severe AQI of 404, placing it in the 'Severe' category. Other major monitoring stations also showed alarming readings: ITO at 345, Jahangirpuri at 339, and Wazirpur at 338, all firmly in the 'Very Poor' zone. The situation was slightly better but still concerning in areas like RK Puram (AQI 311) and Punjabi Bagh (AQI 310).
Meteorological conditions are playing a crucial role in trapping pollutants. Officials from the India Meteorological Department (IMD) pointed to calm winds and low temperatures as the primary culprits. These conditions prevent the dispersion of particulate matter, allowing smog to accumulate and linger over the region. The minimum temperature was recorded at 13.4 degrees Celsius, which is typical for this season but contributes to the inversion layer that caps pollution.
GRAP Stage II Measures in Force
In response to the deteriorating air quality, the Commission for Air Quality Management (CAQM) has mandated the continued implementation of Stage II of the Graded Response Action Plan (GRAP). This stage is activated when the AQI is predicted to remain in the 'Very Poor' category. The enforced measures are designed to curb emissions from key sources.
The restrictions under GRAP Stage II include a specific focus on dust control and waste management. Authorities are ensuring strict compliance with the following actions:
- Regular mechanized cleaning and water sprinkling on roads to suppress dust.
- A complete ban on the use of coal and firewood in hotels, restaurants, and open eateries.
- Stringent enforcement to prevent the burning of municipal solid waste and biomass.
- Increased vigilance at pollution hotspots to check for violations.
These measures are part of a proactive strategy to prevent air quality from slipping into the 'Severe' category, which would trigger even stricter Stage III actions.
Health Advisories and Public Concern
The persistent 'Very Poor' air quality has direct implications for residents' health. Doctors and health experts have reiterated warnings, especially for vulnerable groups. Children, the elderly, and individuals with pre-existing respiratory or cardiac conditions are advised to limit outdoor activities. Common symptoms being reported include irritation in the eyes and throat, coughing, and breathing difficulties.
Environmental scientists have linked the current spike to a combination of local emissions—from vehicles, construction, and industrial activities—and unfavorable weather patterns. While farm fire counts in neighboring states have reduced, the existing pollutant load is not dispersing. The forecast suggests that winds are likely to remain slow for the next few days, meaning relief from the smog is not imminent. Citizens are urged to use public transport where possible and heed the health advisories issued by the authorities until conditions improve.
