New Delhi awoke to another day of dense smog on Sunday, with the city's overall Air Quality Index (AQI) recorded at 351. This reading places Delhi firmly in the 'very poor' category, according to data from the Central Pollution Control Board (CPCB), signifying continued hazardous conditions for residents.
While the current AQI marks a slight improvement from Friday's 'severe' reading of 403, and Saturday's 348, pollution levels remain a significant health concern, particularly for vulnerable populations such as children, the elderly, and individuals with respiratory conditions. PM2.5 particulate matter has been identified as the dominant pollutant across 51 of the 59 monitoring stations in the capital.
Pollution Hotspots Persist Across the Capital
Despite the citywide average, several areas within Delhi continued to experience critically high levels of pollution. On Sunday morning, specific monitoring stations reported AQI levels well into the 'severe' category:
- IIT Delhi: 426
- North Campus: 400
- Pusa: 403
- NSUT Jaffarpur: 407
Other areas like Chandni Chowk also recorded a high AQI of 384, underscoring the localized severity of the air crisis even as the overall average showed a marginal dip.
Restrictions and Weather Conditions
In response to the deteriorating air quality, Stage III of the Graded Response Action Plan (GRAP) remains in effect across the National Capital Region (NCR). These restrictions include a ban on most construction activities and limitations on certain categories of vehicles to curb additional emissions.
Weather conditions on Sunday offered little relief, with foggy skies, a temperature of 21 degrees Celsius, high humidity at 91 percent, and low wind speeds of 3.7 km/h. These atmospheric factors contribute to trapping pollutants close to the ground, exacerbating visibility issues and prolonging exposure to harmful particulates. While forecasts suggest potential rainfall could offer temporary relief, experts caution that lasting improvement requires sustained efforts to reduce emissions from vehicles, industrial activity, construction dust, and stubble burning.
Health Advisories and Public Action
Health officials continue to advise residents to take precautions. Recommendations include avoiding outdoor exercise, keeping windows closed during peak pollution hours, and using certified air purifiers indoors. Anyone experiencing breathlessness, chest discomfort, or persistent coughing is urged to seek medical attention. The Delhi government's portal also provides a pollution-control helpline at 1800 202 5051 for reporting instances of open burning, dust, or industrial smoke.
