Air Quality (indoor)

Air pollution is not just a problem affecting the outside environment.  Levels of air pollutants in homes, indoor workplaces, and schools may exceed levels found outdoors and people spend approximately 90% of their time in these environments. The sources and causes of indoor air pollution are varied and may include:

  • sub-standard housing that may increase exposure to mold, allergens and asbestos,
  • placement of housing in areas with high concentrations of outdoor air pollution, such as adjacent to freeways and railyards,
  • inadequate ventilation that can trap fumes from cleaning products, kerosene heaters and tobacco use, and
  • naturally occurring radon found in soils, rocks and water.
