Haze shrouded the national capital today as weather conditions marked by moisture and calm wind kept the level of pollutants on the higher side and the air quality 'very poor'.
Although the 24-hour-average air quality was a shade better than yesterday, Central Pollution Control Board (CPCB) recorded it at 399, just two notches below 'severe'.
The average (rolling) levels of PM 10 and PM 2.5, microscopic particulates suspended in the air, were 182 and 314 micrograms per cubic metre (ug/m3) as per the readings of System of Air Quality and Weather Forecasting and Research (SAFAR).
