There are several causes of air pollution, most of which are man-made. A major contributor of air pollution is the emissions from vehicles and industrial factories. Cars on the road cause smog, and companies who use or produce chemicals as a byproduct of their industries emit chemicals into the air that affect land, animals and humans.

On a smaller scale, items used in the household may also contribute to air pollution. Products used in everyday home tasks may emit toxic fumes that are harmful in environments that are not well-ventilated. Finally, there are sources of air pollution that are natural and not man-made. This includes the dust and smog from natural events such as volcanoes and dust storms.

When air pollution exceeds a certain level, there is an increase in the incidence of upper respiratory conditions in humans such as allergies and asthma. Lung disorders may also arise from exposure to polluted air. In addition to those with upper respiratory issues, people with cardiovascular problems may find their conditions worsen with increasing levels of air pollution.
