Delhi finds breather as air quality improves with faster winds
People of Delhi received much-needed respite from the toxic air pollution as the air quality index (AQI) improved slightly in last two consecutive days.
On Tuesday morning, AQI of national capital improved from 'severe' to 'very poor' category. It witnessed further improvement as AQI slipped to 'poor' category on Wednesday morning.
Pollution authorities had declared 'health emergency' in Delhi-NCR a week back. It had prompted the Supreme Court to ban construction activities in entire Delhi and its adjoining cities of Noida, Greater Noida, Ghaziabad and Gurugram.
As per the reports, on Wednesday morning, PM 10 was recorded at 178 in the moderate category while PM 2.5 was recorded at 105 in the poor category. Reports suggested that there has been a huge improvement in air quality since Tuesday.
The AQI at 249 is less than half the peak levels seen on Sunday when the capital was caught in a disastrous situation. While many measures have been taken by authorities, the weather conditions are playing the most important part.
According to an earlier forecast by Safar India, the AQI is rapidly recovering from the severe category largely due to faster winds. The trend seen on Wednesday also emphasises the point that stubble burning is just one factor in the overall pollution paradigm.
