Delhi's AQI Plummets: Capital Grapples with 'Very Poor' Air Quality

Delhi's air quality index sank into the 'very poor' category, registering over 330 AQI in multiple areas, largely due to northwest winds carrying pollutants from neighboring states. Environment Minister Gopal Rai urged federal intervention, highlighting the prevalent stubble burning as a contributory factor among others impacting the region's air quality.

On Thursday, the air quality in Delhi deteriorated drastically, falling into the 'very poor' category with an Air Quality Index (AQI) surpassing 330 across many parts of the capital. According to data from the Central Pollution Control Board (CPCB) at 7:00 AM, particularly significant readings were observed at Anand Vihar (392), Ashok Vihar (350), IGI airport T3 (334), ITO Delhi (324), RK Puram (359), Okhla Phase-2 (322), Ashok Vihar (350), and Dwaraka-Sector 8 (348).

The overall air quality in Delhi fell within the 'very poor' category with values ranging between 301-400, while a 'severe' category is marked by AQI from 401 to 500. The India Meteorological Department (IMD) has forecasted maximum and minimum temperatures of 33 degrees Celsius and 19 degrees Celsius, respectively, for the day.

Environment Minister Gopal Rai voiced significant concerns over escalating pollution levels, attributing a rising trend to the northwest winds likely exacerbated by stubble burning in neighboring states. Rai revealed ongoing communication with the Union Environment Minister and proposed exploring research from IIT Kanpur on artificial rain to combat the pollution crisis.

Experts acknowledge the impact of stubble burning on air quality but emphasize its limited role—6-8% throughout the year and up to 25-30% during peak months like October and November. Professor Sagnik Dey of IIT Delhi highlighted the necessity of addressing multiple pollution sources instead of solely focusing on stubble burning.

High pollution levels continue to impact Delhi's water sources as toxic foam was once again reported in the Yamuna river at Kalindi Kunj.
