Transportation

The use of private vehicles (particularly older, diesel models) is the major source of urban air pollution. People use their own vehicles instead of public vehicles which would save the use of petrol and diesel and help in regulating the traffic.

Industrialization

Industrialization is also a major contributing sector in urban air pollution as the area having industries particularly show poor air quality. Factories release many toxic gases due to the burning of fossil fuels and the use of chemicals. These gases react with each other and with other atmospheric constituents to harm us and our environment.

Power generation

With increased population, there is an increased energy demand. To fulfill that demand, fossil fuels are tremendously being used to generate energy as they are cheap and are easily available. The coal powered power plants are a major source of urban air pollution.

Agricultural Activities

From the process of sprinkling of the artificial pesticides and fertilizers till the process of burning the stubble(parali), this constitute a major part to the pollution in urban cities through air and soil pollution, which later affects the human body.

Plastic usage

The increased use of plastic products in our day to day life has not only increased pollution but it plastic products containing BPA and other harmful chemicals also affect human body.
