Smog Chokes Delhi
New Delhi,2 December: The quality of air in Delhi is going through one of its worst smog spells this season, largely falling in the ‘very poor’ category with the National Air Quality Index recording ‘severe’ level of pollutants in so many areas. System of Air Quality and Weather Forecasting and Research (SAFAR) monitoring stations, located across the city in areas such as Delhi University, Dhirpur, Mathura Road, Pusa road had AQI of PM 2.5 and PM 10 above 300 and 200 respectively, considered ‘very poor’. “Very poor” signifies PM 10 and PM 2.5 levels between 351 and 420 and 211 to 252 microgram per cubic metre.
“Severe” is declared when PM 2.5 and PM 10 cross 253, 421 micro gram per cubic metres respectively. Delhi Pollution Control Committee’s real-time readings showed that suspended particulate matter, PM 2.5 and PM 10, levels were way above the safe limits of 60 and 100 micrograms per cubic metre in multiple areas of the city. The phenomenon of smog, a harmful mixture of smoke and fog, experts say, is a play of multiple factors including high moisture levels, vehicular and industrial emissions and lack of wind movement.
