The Science of Indoor Air Pollution

In this activity, students explored the following properties of air.

Many kinds of gases and particles travel through, and become dispersed in the air in our homes. Among households 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. Cleaning and personal products also contribute chemicals to air. Other indoor pollutants, such as pollen, spores, insect parts and droppings, and dust mites come from biological sources. 

Substances become more concentrated in enclosed spaces. The concentration of many of these compounds is much higher indoors than outdoors because 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.
