Delhi Chokes: AQI Crosses 450, Emergency Measures Imposed Amid Toxic Haze

• Delhi's air quality plunges to 'severe' with average AQI at 393, exceeding 450 in hotspots like Chandni Chowk (455) and Wazirpur (449).
• Neighboring NCR cities like Noida (416) and Ghaziabad (360) also grapple with hazardous pollution levels.
• Strict measures include banning non-BS-6 private vehicles from outside Delhi and 'No PUC, No Fuel' policy at petrol pumps.
• Slow winds, cold weather, vehicle emissions, construction dust, and stubble burning from Punjab and Haryana are worsening conditions.
• Doctors advise N95/N99 masks, avoiding outdoor activities, staying indoors, and using air purifiers, especially for vulnerable groups.
