The selection of carbon monoxide and sulfur dioxide as common air pollutants produced by manufacturing and vehicles is supported by the nature of their emissions. Carbon monoxide is primarily generated through the incomplete combustion of fossil fuels, most notably in vehicle engines. As a colorless, odorless gas, it poses significant health risks as well as contributing to atmospheric pollution.

Sulfur dioxide is predominantly produced from the burning of fossil fuels, such as coal and oil, in power plants and manufacturing processes. This gas can lead to the formation of acid rain and has harmful effects on both human health and ecosystems. The production of these two pollutants in industrial and vehicular contexts highlights their relevance in discussions surrounding air quality and environmental health.

In contrast, nitrogen and oxygen are naturally occurring components of the atmosphere and do not typically qualify as pollutants. Ozone, while significant, can be both a pollutant and a protective atmospheric component, depending on its location—ground-level ozone is harmful, but stratospheric ozone protects us from UV radiation. Fluorocarbons and methane, on the other hand, are more closely associated with specific industrial processes, refrigerants, and agricultural practices rather than being direct outputs of typical manufacturing and transportation activities.
