Sources of Air Pollution in the Atmosphere

SOURCES OF AIR POLLUTION IN THE ATMOSPHERE

There are many sources of air pollution you need to consider if it is high in your area. Remember that there is air pollution all over the world and that not all countries have enforceable laws related to reducing this health and environmental problem. The major sources of all types of air pollution include these:

• Burning fossil fuels – this is a major cause of air pollution in all parts of the world. Gasoline, coal, and oil are all fossil fuels used to make energy or to drive vehicles. Carbon monoxide in the air can be a good indicator of how much fossil fuel burning is going on.

• Industries – we don't often see sooty black smoke from factories anymore but there are still emissions to worry about. Factories can emit particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. Most of these use wood or coal as an energy source, with effects on the respiratory system and eyes.

• Volatile organic compounds – these are called VOCs and are a major source of indoor air pollution. It often comes from the use of certain sprays and aerosols.

You will see VOCs in fragrances, cleaning products, and other personal care sprays. Their adverse effects are made worse by poor ventilation in homes, schools, and offices.

• Wildfires – these are much worse due to the effects of air pollution; they are major contributors to air pollution throughout the world. Particulate matter is released along with toxic gases to affect air quality.

• Microbial decay – Bacteria and fungi both release gases, such as methane, as part of their metabolic processes. This is a large global issue because it's these bacteria that are found in the GI tracts of livestock, given off as intestinal gas.

• Transportation – vehicles of all sorts contribute to air pollution. It is more prevalent in urban areas. Areas of high traffic, such as urban areas, will be associated with more problems from this type of air pollution. Vehicles contribute to a hole in our ozone layer, contributing to smog and other health issues.
