The Three Danger Levels
Basic Facts
Most people are aware that outdoor air pollution can damage their health but many do not know that indoor air pollution can also have significant health effects. Environmental Protection Agency studies of human exposure to air pollutants indicate that indoor levels of pollutants may be 2-5 times, and occasionally more than 100 times, higher than outdoor levels. These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their time indoors
| Level One: Allergens & Particulates Dust & Pollen Mold & Fungi Mildew Tobacco Smoke Wood Smoke Vehicle Exhaust Dust Mites Pet Allergens Insect Debris |
Level Two: Infectious Agents Streptococcus Pneumococcus Legionella Tuberculosis Influenza RSV Pneumonia Common Cold Viruses SARS |
Danger Level Three: Toxic Compounds Formaldehyde Corbon Monoxide Methylene Chloride Nitrogen Dioxide Pesticides Toluene & Benzene Tobacco Smoke Toxic Mold |
Three Strategies to Improving Air Quality
