Delhi Pollution

On Thursday, Delhi recorded it’s worst air quality for the first time in this season. The air quality of Near-Capital-Region (NCR) was also very poor. AQI (Air Quality Index) of Noida, Ghaziabad, Gurugram, Greater Noida and Faridabad including Delhi was recorded over 400.

Among these cities, Ghaziabad was the most affected city in Delhi-NCR region with an AQI of 464. Whereas, Faridabad’s air quality was relatively the least affected in the NCR region. Delhi and Noida recorded an AQI of 450 which lies in the category of ‘severe’ air quality.

Every critical region in the capital has surpassed hazardous levels of pollution, according to CPCB (Central Pollution Control Board). This is the main cause that indicates why more than 450 AQIs were recorded in most of the critical areas of the capital. Delhi has surpassed a dangerous condition because a fall of 600 meters in the mixing height has been observed, the spike in incidents of stubble burning and slow speed of the winds which blow from the north-west direction, according to Safar, the air standards body of the Ministry of Earth Sciences.

On Thursday, Delhi’s adjoining states Uttar Pradesh, Harayana and Punjab recorded the most number of stubble-burning incidents. About 4135 incidents were reported in a single day. Forty percent of the total pollution was observed due to the generation of PM (Particulate Matter) 2.5.

Whopping jump in the PM10 and PM2.5 levels have contributed in the rise of pollution in the Capital and NCR. In Delhi, PM10 level was recorded as 498 and PM2.5 level was observed as 336 by Safar, on Thursday.

Critical zones like Wazirpur, Dwarka, Bawana, and Mundka continue to be in a hazardous level of pollution. The worst affected zone was Vivek Vihar which recorded an average AQI of 474.
