Delhi's Air Quality Index Drops from 1300 to 400 from Night to Day

Delhi's air quality monitoring stations recorded an AQI of 1300 during the night, a level classified as hazardous and beyond the safe limit. By the next morning, readings had fallen to 400, still in the unhealthy range but a significant improvement. The sharp decline suggests a reduction in particulate matter and other pollutants, possibly due to lower traffic and industrial activity overnight. Environmental authorities are monitoring the trend closely to assess the effectiveness of pollution control measures. The change highlights the volatility of Delhi's air quality and the need for sustained mitigation efforts.
