    Abstract: Air pollution is the introduction into the atmosphere of chemicals, particulates, or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or environment. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems. A substance in the air that can be adverse to humans and the environment is known as an air pollutant. In our study, we consider the characteristics such as year of manufacturing, types of makers, types of model, vehicle’s weight, odometer readings and different pollutants (i.e., CO, CO2, HC, AFR & Lambda) produced by different vehicle’s. From the analysis it is observed that CO and CO2 is the most influencing environmental components.

    Keywords: Atmosphere, Environment, Planet Earth, Earth’s ecosystems, Air pollution, AFR, Lambda, Odometer Readings.
