Air pollution in New Delhi exceeds WHO standards by more than 30 times
Three days after tightened measures — restrictions on transport and construction — PM2.5 levels in New Delhi reached 461 µg/m³. Authorities expect deterioration ahead of Diwali, when fireworks will add to the pollution. According to India's environment ministry, the largest contributions come from secondary particles (27%) and transport (23%).
