Air pollution is caused when air in the atmosphere is filled with particulate matter.
The largest source air of pollution in cities is from vehicle exhaust fumes.
Carbon monoxide is the largest air pollutant in the United States, and it’s number one source is from vehicle exhausts.
Carbon monoxide is a poisonous, odorless, colorless gas that is formed when burning fossil fuels such as coal, petroleum and natural gas.
Filters that are not changed regularly in your air conditioning units will accumulate dirt and cause the spread of pollutants in the air you breathe inside your home.
Chemicals and toxic pollutants likes sulfur dioxide, nitrogen oxides and carbon dioxide react with water molecules in the atmosphere to produce acid rain. These pollutants come from factories, automobiles and any industrial or manufacturing plants.
Another source of air pollution is from dust and dirt that goes airborne due to every day labor in the agricultural and construction industry. Dust is lifted from tractors working on fields, and from land clearing and general demolition in the construction industry.
Using household chemicals without adequate ventilation is a major source of indoor air pollution.
Volcanoes, dust storms, and forest fires are causes of natural air pollution
