• We spend 90% of our lives in buildings. We spend 27 years of our lives in bed! As a result, most of the chemicals that we inhale are from indoor air. Indoor air has more chemicals than outdoors.
  • The concentrations for most chemicals indoors are higher indoors than outdoors. This is due to 1) emissions from building products, people, cleaning agents, cooking, and consumer products (toys) and 2) chemical reactions indoors.
  • We inhale more air mass per day then we drink water mass. Hence, we tend to inhale more unintentional chemicals per day than we drink.
  • We care about what goes into our students’ bodies. We require a permission slip for our students to use sunscreen and or take medicine. Hence, we care how chemicals get to our students’ skin and mouth. We should also be concerned with chemicals that get to our students lungs.
