Air quality in Delhi deteriorates, enters red zone
The System of Air Quality and Weather Forecasting Research (SAFAR), under the Ministry of Earth Sciences which monitors air pollution said that the air quality of the National Capital has become poor as of today and as much as of prediction, it is likely to worsen in the coming few days.
The Air Quality Index (AQI) maintained by the Central Pollution Control Board (CPCB) has recently sky rocketed to 219 (poor) and a poor AQI essentially means that people will have breathing discomfort on prolonged exposure to such air. A further dip in the air quality, AQI will turn ‘very poor’ and ‘severe’.
“PM10 and PM2.5 have found to be the primary pollutants which are responsible behind this rise in air pollution in Delhi,” said D Saha who heads the air quality laboratory of CPCB.
According to SAFAR, the concentration of these pollutants is likely to shoot up in the next few days. While the PM10 is likely to increase from 178 micrograms per metre cube to 192, the PM2.5 is likely to increase from 94 micrograms per metre cube to 110 micrograms per metre cube respectively.
Experts said that there are only two reasons behind the bad air quality. On one hand crop burning in neighbouring Punjab and Haryana which is the primary reason and on the other hand meteorological conditions include a cyclonic circulation and a fall in wind speed aggravating the situation.
