What are the things indoors that should concern me the most?
Most people spend about 90 percent of their time indoors―in their homes or other buildings. So for many people, the health risks of indoor air pollution are greater than those outdoors. Gases are the main cause of indoor air problems in homes. Their sources include: • oil, gas, coal, wood, kerosene, and tobacco products • materials used to build your home, such as insulation • home furnishings, such as cabinets made of certain pressed wood products • cleaning, pest control, painting, and personal care products These are other common sources of indoor air pollution: • bacteria • molds and mildew • animal dander and cat saliva • dust mites • cockroaches Having poor air flow, or ventilation, in combination with heating and cooling systems can also cause indoor air problems. Radon, pesticides, and other outdoor sources of pollution can enter your home through cracks in walls, opened windows, and fans. Hot and humid weather can also increase levels of some pollutants.
