PY - 2013 T2 - CURRENT Diagnosis & Treatment: Occupational & Environmental Medicine, 5e AB - The Clean Air Act, passed in the mid-1960s, focused national attention on cleaning up outdoor air but directed little interest toward improving the quality of indoor air—even though people spend only 10–20% of their time outdoors and the rest of their time indoors at home or at work. Studies conducted during the past three decades confirm that indoor air quality (IAQ) problems can cause or contribute to a variety of symptoms and sometimes illnesses in building occupants, as well as reductions in productivity. Concentrations of some pollutants inside buildings may exceed standards established for outdoor concentrations.
