A layer of haze covered the national capital for the fourth day as air pollution makes its comeback. The air quality went from “poor” to “very poor” category with AQI crossing the 300 mark in most areas in Delhi and neighboring regions.
AQI crossed the 300 mark
The AQI in Anand Vihar, Wazirpur, Vivek Vihar, Mundka, Bawana, Jahangirpuri was 327, 323, 317, 309, 302 and 300 respectively, according to Central Pollution Control Board data.
The air quality in neighboring Ghaziabad (320), Greater Noida (312) and Noida (310) in Uttar Pradesh and Haryana’s Alipur Khalsa (351) and Panipat (339) also turned “very poor”.
An AQI between :
0 and 50 is considered ‘good’,
51 and 100 ‘satisfactory’,
101 and 200 ‘moderate’,
201 and 300 ‘poor’,
301 and 400 ‘very poor’, and
401 and 500 ‘severe’
Stubble burning contributing to Air pollution
Stubble burning in Punjab and Haryana has also contributed to the rise of air pollution and PM2.5 levels – atmospheric particulate matter with a diameter of fewer than 2.5 micrometers – with the concentration of the pollutant expected to rise to 6 percent.
“The fire counts in Punjab and Haryana have increased significantly over the last two days. The wind direction in Delhi is westerly which is unfavorable thereby carrying the smoke from the stubble burning towards Delhi,” LS Kurinji, a research analyst with the Council on Energy, Environment and Water (CEEW), was quoted by news agency IANS.
“Delhi will probably encounter poor air quality in the coming days due to the prevailing wind direction and the stubble burning,” she added.
The latest images from US space agency, NASA show quite a few numbers of fire incidents occurring in the North-western region of India and adjoining regions in Pakistan. They are likely due to crop burning in the area and will bring pollution to different parts of India, including Delhi-NCR.
Kejriwal asks Delhi to be prepared
Delhi Chief Minister Arvind Kejriwal has issued a statement warning the people of the national capital and adjoining areas to be prepared for the upcoming months.
He added that the smoke from crop stubble burning in neighboring states has started reaching Delhi and our air quality has started deteriorating from Good to Moderate to Poor to Very Poor.
“This is not just a question of the air quality in Delhi. Perhaps the largest health impacts of the stubble burning will be faced by the residents of Karnal and other parts of Haryana. Delhi gets the most attention because it has more media, it has the Central Government,” Kejriwal added.
SAFAR warns people
System of Air Quality and Weather Forecasting And Research (SAFAR) issued a health advisory, asking people to reduce heavy exertion.
“People with heart or kind diseases and children should avoid longer and heavy exertion. Everyone may experience health effects. Significant increase in respiratory problems,” it said in a statement.
