The residents of the national capital continue to breath polluted air as air quality in the city was recorded under 'very poor' category on Sunday morning.
The System of Air Quality and Weather Forecasting And Research (SAFAR) said the Air Quality Index (AQI) in the national capital was 324 for PM10 and 200 for PM2.5. As PM10 went over 300, the department has issued a health advisory asking people with heart or lung diseases, older adults, and children to reduce prolonged or heavy exertion. The PM2.5 level was found to be under the 'very poor' category.
According to the SAFAR forecast, the pollution levels are expected to deteriorate further in the next 24 hours with PM10 likely to be at 356 and PM2.5 at 220.
An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', then 401 and between 500 is considered 'severe'.
