What is indoor air pollution and how can I be exposed to it?
Most people spend about 90 percent of their time indoors. Therefore, indoor air pollution is as great a concern as outdoor air pollution. Sources of indoor air pollution include: • Gases from burning oil, gas, coal, or wood for heating and cooking • Smoke from tobacco products • Building materials, such as asbestos insulation and products made from pressed wood • Outdoor pollutants, such as radon, that can accumulate indoors • Chemicals used for cleaning, pest control, and painting • Personal care products such as hair spray and nail polish remover • Biological contaminants, such as bacteria, molds and mildew, and pet dander If your home does not have enough ventilation, pollutants may build up to unhealthy levels.
