The air quality in the national capital remained under 'poor' category at various places as people woke up to a hazy morning on Monday.
Though the overall Air Quality Index (AQI) of Delhi improved on Monday (272) as compared to Sunday (326), the thick smog continued to engulf the national capital and is expected to make the situation worse in coming days, according to System of Air Quality and Weather Forecasting and Research (SAFAR).
An AQI between 0-50 is considered good, 51-100 is satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor and 401-500 is marked as severe/hazardous.
The India Meteorological Department has advised people to restrict outdoor activities, especially those having breathing issues.
Apart from vehicular and industrial pollution practices like residue crop burning and use of bio-mass, such as cow-dung, wood and coal, also aid air pollution. With a large population relying on these practices, efforts to curb the menace of pollution need stringent measures.
