Pre-Diwali pollution grips Delhi-NCR, AQI touches 349 at ITO, Akshardham

New Delhi: Delhi-NCR is once again under the grip of air pollution. Polluted air has started to engulf the national capital and the surrounding areas of Noida, Gurugram and Ghaziabad. The Air Quality Index (AQI), which was below 100 just a few days ago due to rains, has now reached nearly 350.

According to the Central Pollution Control Board (CPCB) the AQI in the area around Akshardham Temple is 349 this morning. This comes under the ‘Very Poor’ category. Reports said that just within a day, the AQI jumped by 144 points. On Saturday, the average AQI of Delhi was 117, which was in the ‘Moderate’ category. The very next day, that is Sunday, it reached 261, reported Amarujala.com.

By evening after 6 pm on Sunday, the AQI had risen further and reached 272. Following this increase, the AQI in Delhi reached in the ‘Poor’ category.

According to data from the Central Pollution Control Board (CPCB) monitoring stations, air quality in 43 out of Delhi’s 59 monitoring stations was recorded in the ‘poor’ to ‘very poor’ category. Of these 23 areas have recorded AQI above 300, while in another 20 the AQI is in the ‘Poor’ category. In just 14 of the areas the AQI is in the ‘Moderate’ category.

Apart from Akshardham the AQI around ITO is also in the ‘Very Poor’ category. It was recorded at 349, earlier in the day, said the CPCB.

Impact of stubble burning

According to an estimate made by scholars at IIT Mumbai, the contribution of stubble burning to pollution in Delhi was estimated to be around 18 percent. Due to winds blowing from the north west on Sunday, the pollutants from the direction of Punjab and Haryana could reach Delhi.

In addition, vehicle emissions, construction activities, and local pollution are also degrading air quality. According to experts, wind direction and speed influence the dispersion of pollutants. In such a situation, along with local emissions, pollution originating from external sources is also affecting Delhi’s air quality.
