The generation of nitrogen oxide causes by vehicles, power plants, and industries and often burning fuel in household cooking.
Because city dwellers have heavy traffic and live near busy roads, they expose to nitrogen dioxide pollution at higher rates than rural dwellers.
According to the World Health Organization (WHO) Air Quality guidelines, the acceptable annual presence of PM 2.5 is five micrograms per cubic meter, and Nitrogen Dioxide is ten micrograms per cubic meter.

The two organizations said that India’s capital New Delhi tops the list of cities with the most polluted air in the world. The average annual concentration of Particulate Matter PM2.5 in the city is 110 micrograms per cubic meter.
The second one is Kolkata; another Indian city with an average annual concentration of PM2.5 is 84 micrograms per cubic meter annually. Apart from this, the third place in the list is 83.6 micrograms for the city of Kano, Nigeria.
