Air quality plunges to 'very poor' category in Delhi
The air quality of national capital took a hit after Diwali night due to a combination of firecracker emissions, stubble burning and unfavourable meteorological conditions. According to the Air Quality Index (AQI) data and System of Air Quality and Weather Forecasting and Research (SAFAR), major pollutants in Delhi's Lodhi Road area were PM 2.5 at 500 (severe) and PM 10 at 379 (very poor). Pollution levels have been oscillating between the lower end and the higher end of the 'very poor' category. The higher value of AQI indicates greater level of air pollution and health concern. Delhi residents have complained of a spike in respiratory problems and allergies. The stubble burning in Punjab and Haryana makes the situation in Delhi more worse. To curb air pollution, the Arvind Kejriwal led-government in Delhi has announced the implementation of the Odd-Even scheme from November 4-November 15.
