According to the Newspaper,“As the wind speed increased, it flushed out pollutants and moisture. With a clear sky and the sun shining brightly, the mixing height increased, allowing the pollutants to disperse faster,” said D Saha, head of the air quality laboratory at Central Pollution Control Board. Officials said areas close to the Delhi Technical University (DTU) had the worst air quality on Wednesday, with the monitoring station recording PM 2.5 level at 497. The other areas which had severe pollution level were DTU, Anand Vihar, and RK Puram. The Delhi government on Monday had issued a health advisory urging schools to avoid outdoor activities during morning following predictions that air pollution might rise over the next three days.
