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 and PM 10 at 500 both in 'severe' 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 04-November 15.
