Basic Air Pollution Facts

Below are some facts and info on environmental pollution.

  • WHO reports that in 2012 around 7 million people died – one in eight of total global deaths – as a result of air pollution exposure. This finding more than doubles previous estimates and confirms that air pollution is now the world’s largest single environmental health risk. Reducing air pollution could save millions of lives.

  • Air pollutants (dangerous things that make the air unclean)come in the form of gases or particles.
  • It is estimated that you breathe 20,000 liters of air each day. This means the more polluted the air is, the more we breathe dangerous chemicals into our lungs.
  • Air can be polluted both indoors and outdoors. Tobacco and other kinds of smoking are examples of indoor air pollution.
  • Sick Building Syndrome is a health condition related to pesticides, insecticides, and chemicals we use at home and in offices.
  • In the great “Smog Disaster” in London in 1952, four thousand people died in a few days due to the high concentrations of pollution. London’s air was filled with sooth and carbon dioxide, mixed with fog, creating a very toxic air called Smog.
  • Air pollution affects kids more than adults because, for their body size, kids breathe more air and spend more time playing outside.
  • More hazardous pollutants are discharged into the air each year than are released to surface water, groundwater, and land, combined.

Motor vehicles produce more air pollution than any other single human activity. One full commuter bus can mean 40 fewer cars going through your neighborhood.

In America, vehicle exhaust contributes roughly 60% of all carbon monoxide emissions nationwide and up to 95% in cities.
