Home testing is the only way to assess exposure to radon. Homes with high levels of radon require increased indoor-outdoor air exchange. Some may need structural work to reduce radon levels. Managing Indoor Air Pollution To manage indoor air pollution, you must first identify the con- taminants. Often, removing or replacing an object or appliance and providing sufficient indoor-outdoor air exchange will solve the problem. Make sure that hot water heaters and furnaces are prop- erly vented and operating efficiently to avoid a buildup of carbon monoxide. Many families have installed carbon monoxide detec- tors to warn of a toxic buildup. Similar detectors are available for radon. Homeowners who discover the presence of asbestos or lead should seek professional help in removing these contaminants. radon asbestos 769 Lesson 1 Air Quality What is sick building syndrome? The term sick building syndrome (SBS) refers to a situation in which the occupants of a building experience health problems that seem to be linked to the atmosphere within the build- ing. Symptoms of SBS include headache; itchy and irritated eyes, throat, or nose; dizziness and nausea; fatigue; inability to concen- trate; and a sensitivity to odors. SBS sufferers often report relief soon after leav- ing the building. health.glencoe.com TOPIC Indoor Air Pollution Go to health.glencoe.com and click on Web Links for information on ways to minimize indoor air pollution.

In the 1960s children and teens were outside at least three hours each day. Today, they are out- side less than two hours each day. How might these facts relate to the increase in asthma? Today’s homes allow less air to circulate. How might this contribute to the increase in asthma? What can be done to increase ventilation? Tobacco smoke is one of the leading contributors to asthma attacks. How can exposure to tobacco smoke be limited or prevented? Work with a small group. Use reliable library and online sources to investigate additional measures that can improve indoor air quality. Cite your sources, and provide an explanation of why each source is reliable.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
