Top 10 most Polluted Cities in India

India is one of the fastest growing countries in the world and industrialization is the major cause of development. Due to the large scale industrialization, emission of harmful particles and gases have increased leading to increase in pollution. Pollution is not only harmful to human being but also causes an adverse effect on birds and animals.

Pollution in India with the passage of time is increasing rapidly and some of the reasons are emission of smoke from vehicles, burning of biomass and fuels, emission of harmful gases from industries and the emission of greenhouse gases. As a result of increase in pollution, the quality of air in the country has degraded resulting in numerous diseases.

Particulate Matter (PM) is term used for solid or liquid particles present in air that impacts adversely on human health and environment. PM is a unit of measurement of air pollution and higher the value of PM denotes the higher pollution. PM 2.5 is a particulate matter with particles with a size of 2.5 micrometres or less. Among all cities in India, Delhi is the most polluted city with PM 2.5 concentration of 153 µg/m³ and its air quality is degrading swiftly.
