Beig explained that one of the reasons behind Wednesday’s jump was “secondary aerosol formation,” wherein particles mix with water molecules of fog, thus “multiplying” the amount of pollutants.5 and PM 10 are 60 and 100 micrograms per cubic metre respectively while World Health Organisation considers 25 to be the maximum safe level of PM 2.Wednesday was the most polluted day of the year in Delhi with the average of PM 2.According to Indian authorities, the safe limits of PM 2. Anand Vihar’s AQI was “severe”, with the most prominent pollutant being PM 10.Even that phenomenon has ceased, the chief project scientist of Safar said while adding that the situation would be relatively better on Friday and the day after.
Although there is a likelihood of increase from December 27 onwards due to westerly disturbances, Mr Beig said. Scientist Gufran Beig of System of Air Quality air cylinder valve suppliers and Weather Forecasting and Research (Safar) told PTI that wind speed increased by up to three times and swept away the pollutants and a drop in humidity only aided the clean up.5.Meanwhile, Central Pollution Control Board’s national air quality index could not be accessed as most of its stations continued to display figures of December 23.A day after spiralling to alarming levels, pollutants in Delhi’s air reduced considerably as strong wind considerably dispersed suspended particulate matters, PM 2.5 and PM 10, prompting authorities to forecast a relatively cleaner Christmas Day.The average level of PM 2.5, tiny particles that can embed themselves deep in the lungs and enter the bloodstream.
