Why is Delhi’s Air Quality Breaching 400 Today?
Synopsis
Key Takeaways
New Delhi, Nov 2 (NationPress) The capital city has experienced a significant decline in air quality this morning, with pollution levels plunging into the ‘very poor’ category and reaching ‘severe’ thresholds in various areas of Delhi-NCR. A thick layer of smog combined with calm morning winds has trapped pollutants near the ground, leading to drastically reduced visibility and exacerbating breathing difficulties throughout the region.
As reported by the Central Pollution Control Board (CPCB), the average Air Quality Index (AQI) in Delhi was recorded at 372 at 6:30 a.m., firmly categorizing it as ‘very poor’.
The situation deteriorated further in numerous locations, where AQI values surpassed the 400 threshold, signifying ‘severe’ air quality. Some of the most polluted areas included Wazirpur (425), Bawana (410), Rohini (409), RK Puram (418), and Dwarka (401), all exhibiting hazardous pollution levels. Overall, most monitoring stations throughout the city displayed AQI values ranging between 300 and 400, indicating widespread toxic air.
The air quality in the NCR region was similarly concerning, with cities like Faridabad (312), Gurugram (325), Greater Noida (308), Ghaziabad (322), and Noida (301) all falling into the ‘very poor’ category based on AQI readings.
Weather conditions played a significant role in the accumulation of pollution, as the primary meteorological station at Safdarjung noted a visibility of 900 meters, while Palam reported 1,300 meters, both due to a combination of fog and smog. The wind speeds remained low at around 4 km/h, inadequate for dispersing the trapped pollutants.
The India Meteorological Department (IMD) noted that Delhi recorded a maximum temperature of 30.5 degrees Celsius, approximately three degrees below the seasonal average, with a minimum temperature of 19.4 degrees Celsius, which is slightly above normal. Humidity was reported at 73 percent on Saturday evening, further contributing to smog formation.
With an AQI of 303 recorded on Saturday night, already in the ‘very poor’ range, stagnation and low wind speeds overnight resulted in a significant increase by morning.
Experts have cautioned that without strong northwesterly winds or rainfall, air quality is expected to deteriorate further in the upcoming days as stubble burning and local emissions continue to exacerbate the pollution crisis in Delhi.
