Introduction<\/strong>
Air pollution, defined by the presence of harmful substances in the atmosphere, poses a grave threat to human health and the environment. This issue is particularly pronounced in various cities across India, where a notable percentage of harmful chemicals contributes to the deteriorating air quality.<\/p><\/blockquote><\/figure>\n\n\n\n

Sources and Categories of Air Pollution<\/strong><\/p>\n\n\n\n

\n
\n
    \n
  1. Particulate Matter (PM): Fine particles from industrial activities, construction, and vehicle emissions contribute substantially to the air pollution percentage in urban areas.<\/li>\n\n\n\n
  2. Combustion Processes: The combustion of fossil fuels in vehicles, industrial facilities, and power plants emit a significant percentage of pollutants like carbon monoxide (CO), nitrogen oxides (NOx), and sulfur dioxide (SO2).<\/li>\n\n\n\n
  3. Ground-level Ozone: Ozone, a critical component of smog, forms in the presence of pollutants from vehicles and industrial sources, constituting a notable percentage of air pollution. The Air Quality Index (AQI)
    The Air Quality Index (AQI) serves as a numerical metric to convey the state of air purity in a specific location, providing a straightforward means to communicate the current air quality and associated health risks for the
    general population.
    AQI Components:<\/li>\n\n\n\n
  4. Particulate Matter (PM2.5 and PM10): Microscopic particles suspended in the air, where PM2.5
    denotes particles under 2.5 micrometers and PM10 includes particles up to 10 micrometers.<\/li>\n\n\n\n
  5. Ground-level Ozone (O3): A fundamental element of smog formed through the interaction of
    pollutants from vehicles and industries exposed to sunlight.<\/li>\n\n\n\n
  6. Nitrogen Dioxide (NO2): A gas originating from combustion processes, primarily emitted by vehicles
    and industrial activities.<\/li>\n\n\n\n
  7. Sulfur Dioxide (SO2): A gas produced by burning fossil fuels containing sulfur, typically stemming
    from industrial processes.<\/li>\n\n\n\n
  8. Carbon Monoxide (CO): A colorless, odorless gas resulting from incomplete combustion of carbon-
    containing fuels.<\/li>\n\n\n\n
  9. Air Quality Index Categories:
    \uf0b7 0-50: Satisfactory
    \uf0b7 51-100: Acceptable
