Air pollution is defined as any contamination of the atmosphere that disturbs the natural composition and chemistry of the air. It comes from a wide variety of sources, but the most excessive include forest fires and other natural sources, vehicle or manufacturing exhaust and building construction or demolition.
Water pollution involves any contaminated water, whether from chemical, particulate or bacterial matter that degrades the water's quality and purity. The causes of water pollution include increased sediment from soil erosion, improper waste disposal and leaching of soil pollution into water supplies.
Land pollution is contamination of the soil that prevents natural growth and balance in the land, whether it is used for cultivation, habitation or a wildlife preserve. Soil pollution sources include hazardous waste and sewage spills, non-sustainable farming practices and household dumping.
Noise pollution refers to undesirable levels of noise caused by human activity that disrupt the standard of living in the affected area. This type of pollution often comes from traffic, airports, concerts and manufacturing plants.
Radioactive pollution is rare but deadly when it occurs. Sources of radioactive contamination include nuclear power plant accidents, improper nuclear waste disposal and uranium mining operations.
Thermal pollution is excess heat that creates undesirable effects over long periods of time. It may be caused by power plants, urban sprawl and deforestation.
Light pollution refers to the over-illumination of an area that is considered obtrusive. Sources include large cities, billboards and advertising.
Visual pollution can be caused by other pollution or just by undesirable, unattractive views. Some of its sources are power lines, construction areas and neglected areas, such as abandoned buildings.
Personal pollution is the contamination of one's body and lifestyle with detrimental actions. This may include excessive smoking, drinking or drug abuse and emotional or physical abuse.
