Molds also release chemicals into the air that can make you feel very tired or sick. There are many other sources of indoor air pollution. Lead was used in most paints manufactured prior to 1978. Asbestos was used in insulation, flooring and plasters. Although paint no longer contains lead and asbestos is no longer used, these dangers may still lurk in older homes.
Products stored inside our homes can also pose a danger.
Pesticides, the sprays, powders, and foggers we keep in our closets or cupboards to kill insects and disinfect our bathrooms can release fumes that can irritate our respiratory systems. Some can even increase the risk of cancer. Some outdoor pollutants can also become indoor pollutants. Radon, a radioactive gas from soil and rock, is one such hazard. Radon can enter a foundation and collect inside a home.
