Air pollution is a mixture of many different substances and the exact contents vary depending on what sources of pollution are nearby, your location, the time of year and even the weather. Sources of air pollution can be man-made, such as fumes from vehicles and smoke from burning fuels. While others, such as North African desert dust and radon gas, are natural.
Air pollution is often separated into outdoor air pollution and indoor air pollution.
Although both indoor and outdoor air pollutants have been shown to increase the risk of cancer, it’s important to keep the risk in perspective.
Smoking has a much bigger effect on the risk of developing lung cancer than either outdoor air pollution or radon do. If you smoke, the best thing you can do for your health is to quit.
