Air Pollution


Air pollution results when substances that are potentially harmful to living things find their way in to the atmosphere. These substances are collectively known as air pollutants and can be natural or man-made.

Air pollutants can be in the form of solid particles, liquids or gasses and can be classed as primary or secondary pollutants. Primary pollutants are those that are put there directly, like the exhaust from cars while secondary pollutants are those that form there from the interactions of primary pollutants. Smog often results in cities because of the interaction of car and industrial exhaust and the ultraviolet part of daylight.
Air pollution comes from two main categories of source, Anthropogenic sources are those that result from human activity especially fuel burning activities like producing power, transport and even forest clearing in some countries. Aerosol fumes and other chemical pollutants also fall into this category. The second category is the natural pollution sources, such as volcanoes and dust from dry areas with no vegetation as well as methane from animals.

Air pollution occurs inside the home too. Carpets and paints emit off several different chemicals and a stove or fireplace can add smoke particles to the air.

Air pollution can be a contributing factor in respiratory diseases and lung cancer amongst other health conditions. Millions die each year as a result of poor health caused by air pollution, particularly in poorer nations. In 1984 an industrial accident in India killed over 25,000 and injured many times that when industrial fumes leaked into the atmosphere.

Indoor air pollution and the quality of air in our cities are considered to be amongst the world’s worst pollution challenges.

Air Pollution - Friends of the Earth: Inhale

The image of the back of a car is printed on the lid, with the straw in place of the exhaust pipe. The lid is distributed and used by road-side food stalls. When consumers drink from this cup on the streets, it would be like they were inhaling toxic emissions directly from the vehicle. “Pollution […]
