There's Something in the Air
The Science of Air Pollution
During this activity, students observed the following properties of air.
- Many kinds of gases and particles travel through, and become dispersed in air. In homes with a fireplace or a family member who smokes, indoor pollutants can include gases such as carbon monoxide, as well as particles, like those that make up soot and tobacco smoke. Other indoor pollutants, such as pollen, spores, insect parts and droppings, and dust mites come from biological sources.
- Cleaning products, cosmetics and hairsprays also contribute to indoor air pollution.
- The concentration of many compounds is much higher in enclosed spaces. Many modern homes and buildings are designed to save energy by preventing air leaks or the introduction of outside air into heating or cooling systems. This often causes airborne chemicals and other substances to build up indoors.
