"Under zero firecracker scenarios, the level of PM2.5 is likely to be the lowest in the past four years as not so calm surface winds in Delhi will help in dispersion," the ministry said. However, stubble burning-induced impact on AQI is expected to increase from negligible to moderate for the next two days. (Text: IANS/Image: Reuters)
