Delhi, UP chokes as air pollution increases on Diwali

Thick smog hanging over Delhi and parts of Uttar Pradesh on the morning after Diwali, with pollution increased up to dangerous level on Monday. Smoke from firecrackers has choked the air and also affected visibility.  


Data from the central pollution monitoring agency showed that concentrations of Particulate Matter or PM 10 (coarser pollutants) was over 1,600 micrograms per cubic metre compared to a safe level of 100 at around 2 am in Delhi.


PM 2.5, a standard measure of air quality, was as much as 14 times the safe limit. These particles can cause respiratory diseases if one is subjected to prolonged exposure to unsafe levels. Seven areas in the national capital region featured among the 10 most polluted places in the country.


Pollution in Delhi peaks during Diwali as a hazardous mix of noxious gases and pollutants hang very close to the surface. The Delhi High Court had described the capital as gas chamber last year. Besides Delhi, Kanpur and Lucknow in Uttar Pradesh also recorded severe pollution. In Agra people can hear cracker busting till 2 am on Sunday-Monday night.


Experts had warned that pollution during Diwali was expected to be worse than the last two years because of a combination of adverse factors like slow wind speed and moisture in the air, a major hindrance in the dispersion of suspended pollutants.


As people celebrated Diwali by bursting firecrackers on Sunday, a NASA photo at about 8 pm showed the top half of India hazy with smoke. Popular spots like India Gate and Rajpath in Delhi were choked with smog.


The pollution monitoring agency has advised people to avoid all outdoor physical activity when air quality is rated severe this morning. People with heart or lung diseases, older adults, and children are advised to remain indoors and keep activity levels low.


A report released by UNICEF on Monday said almost one in seven children worldwide live in areas with high levels of outdoor air pollution, mostly in South Asia, and their growing bodies are most vulnerable to damage.
