Following Diwali, air quality in several cities across northern India plummeted to hazardous levels, with AQI readings exceeding 400 in some areas. Despite measures such as anti-smog guns and construction restrictions in cities like Delhi, pollution levels remain critical, fuelled by stubble burning and firecrackers, and intensified by the onset of winter. The question remains: How is the AQI calculated, and what factors contribute to its sharp decline, especially during winter?

Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
