Delhi’s air quality shifted from being barely breathable to a full blown health hazard on Monday, wind speed to blame this time
Delhi’s air quality index (AQI) jumps 31 units to make Delhi’s air severely toxic.
For the last month Delhi’s air hasn’t been so bad. Last time Delhi’s air hit the ‘severe’ mark, it was November 13.
In a drastic move, Delhi’s air quality index (AQI) that was already in the ‘very poor’ category on Sunday turned ‘severe’ on Monday after it shot up 31 units. The AQI on Sunday was recorded at 373 while on Monday it shot up to 403.
Experts fear that the air quality will remain so until the next two days, after which there is a slight chance of improvement.
System of Air Quality and Weather Forecasting and Research (SAFAR), in it daily pollution analysis observed that the air quality reached the brink of ‘very poor’ (< 400) at most places and ‘severe’ (> 400) at some.
Experts believe that the pollution levels are likely to remain the same for Tuesday, while they may decline after it. The low temperature mixed low wind velocity is trapping the pollutants and not letting them disperse properly, plus the moderate fog will further trap gaseous and particulate pollutants. The rain might be able to bring some much needed respite, but if the showers are light they may cause more harm than good because humidity and moisture often traps the pollutants.
Saturday was the coldest day in Delhi, with temperature at 7.6 degrees Celsius, “The rain needs to be sufficient if the pollution has to go down. If there is not enough rain, it will only increase the pollution levels as the moisture will aid in trapping pollutants,” a Central Pollution Control Board official said.
