Indoor Air Quality Concerns
The air inside can harm your family’s health more than the outdoors.
Is the air in your home safe to breathe?
It is not always easy to tell if your home has poor air quality. You may notice bad smells or smoke, but you cannot see or smell other dangers, like carbon monoxide or radon. This chapter and those on asthma and allergies, mold, and carbon monoxide will help you ask the right questions to determine if your home’s air is healthy and safe. They will also give you ideas about how to fix any problems you might find.
Asthma and Allergies
If someone in your home has health problems or is ill, polluted indoor air can make them feel worse. For example, asthma is a lung disease that affects a growing number of children. Indoor air pollution can make
it worse. Insects and other pests can also be a real problem for people with asthma or allergies. For example, cockroaches and dust mite droppings cause asthma attacks in some people. Pesticides can help fight these pests, but they can be dangerous. Use bug spray and other pesticides safely. See page 11 to learn about making your home healthier for people with asthma or allergies.
Mold
Mold grows in damp places. It often smells musty. Many people are allergic to mold. Some kinds of mold are toxic, and coming into contact with large amounts of mold may cause health problems. Talk to a doctor if you think mold is causing health problems for you or your family. See the post on Mold and Moisture to learn more about controlling mold in your home.
Carbon Monoxide
Carbon monoxide is a deadly gas that can come from appliances that burn gas, oil, coal, or wood and are not working as they should. Car exhaust also has carbon monoxide. You cannot see, taste, or smell carbon monoxide. See page 23 for more information on how to protect your family from carbon monoxide poisoning.
Radon Gas
Radon is another gas that can get into some homes from the ground below. You cannot see, taste, or smell radon. It is found all over the United States and can cause lung cancer. It is the second leading cause of lung cancer in the U.S. If you smoke and your home has high levels of radon, your risk of lung cancer is exceptionally high.
• Have you ever tested your home for radon?
• Do any of your neighbors have problems with radon gas? If so, you might also have a radon problem. Living in a Healthy Hom
Indoor Residential Air Pollutants
• Tobacco smoking causes cancer and other major health problems. It’s unsafe for children to be around smokers. Second-hand or environmental tobacco smoke can raise children’s risk of ear infections and breathing problems. It can trigger asthma attacks, too.
• Many families have pets. However, furry pets cause problems for some people. Pets can make asthma and allergies act up, especially if you keep them in sleeping areas.
• Hobbies and home projects sometimes involve sanding, painting, welding, or using solvent chemicals, like varnish or paint strippers. (A solvent is a chemical that can dissolve something else. Solvents are usually liquid.) Home projects can pollute the air with dust or harmful chemicals. Sometimes, indoor air pollution comes from what people have in their homes.
• Some household products, especially those with solvents, can pollute the air if you don’t use them correctly. See Hazardous Household Products for more information about household products
• New furniture, carpets, and building products may give off chemicals used in their making. Some of these chemicals can harm people, especially children.
• If your home was built before 1978, the paint may have lead. Lead is hazardous for young children. See Lead Concerns to learn about protecting your children from lead poisoning.
