What are the layers of the atmosphere that get affected by air pollution?

Air pollution primarily affects the troposphere, the lowest layer of the atmosphere where weather occurs and where most human activities take place. Pollutants such as particulate matter, ozone, and nitrogen oxides can degrade air quality and impact health. The stratosphere, particularly its ozone layer, is also affected; pollutants like chlorofluorocarbons (CFCs) can lead to ozone depletion. While higher layers like the mesosphere and thermosphere are less impacted, pollutants can still influence atmospheric chemistry and climate patterns.
