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. Surveys show that 75 percent of homes in the United States use at least one pesticide product most often insecticides and disinfectants - indoors per year.
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. If there s a smoker in your home, you may be exposed to whole array of pollutants, including carbon monoxide and formaldehyde. More than 40 of these compounds are known to cause cancer in humans or animals and in the very least are strong irritants. All things considered, the air inside your home may be worse than outdoor pollution.
