Delhi Chokes: Stubble Burning Not Sole Smog Culprit
26 Nov
Summary
- Stubble burning's pollution contribution peaked in November.
- Regional cities, transport, and unknown sources significantly pollute Delhi.
- Delhi's AQI remained very poor even with low farm fire contributions.
Delhi's air quality has severely deteriorated, with the AQI soaring to 'Very Poor' and 'Severe' categories throughout October and November. While stubble burning in neighboring states contributes to the pollution, especially in November, data reveals it's not the only culprit behind the capital's toxic air.
Analysis shows that cities surrounding Delhi, vehicular emissions, residential activities, industries, and construction dust also play significant roles. Alarmingly, a substantial 34.8% of pollution stems from unknown sources, hindering effective control measures.
As of November 26, AQI readings across Delhi remained high, with even relatively cleaner areas exceeding safe limits. This complex mix of pollution, extending beyond farm fires to regional factors and unknown contributors, necessitates a coordinated strategy to combat Delhi's winter smog.
