Air pollution refers to the presence of chemicals and other substances in the atmosphere. These chemicals are produced by both manufactured and natural sources. Air pollution can cause or exacerbate ill health effects in humans, such as asthma, emphysema, and respiratory diseases like a chronic obstructive pulmonary disease. A correlation between pollution and increased cases of heart disease and cancer has also been shown. Here are three common sources of air pollution.
1. Traffic Emissions
A large amount of air pollution comes from cars, trucks, trains, planes, and ships, which transport people and goods from one location to another. These vehicles emit carbon monoxide, nitrogen oxide, sulfur dioxide, and other pollutants that contribute to poor air quality. Ozone, which is a harmful gas to breathe, is created from these chemical emissions. If you live near a large highway or airport, it might be beneficial to have sterile air filters
