The possibility of establishing standards for indoor air quality is under consideration, because its importance for protecting human health is recognized as a major national environmental issue. The ever-increasing cost of energy has heightened the need for considering such standards, inasmuch as a cost-effective method of reducing energy use in buildings is to reduce ventilation, an action that can increase indoor air pollution.
There is a regulatory indoor air standard for nonoccupational air in the United States only for ozone. There are voluntary standards for indoor air quality that may serve as guidelines to federal, state, or local government agencies on formaldehyde, carbon monoxide, chlorine, radon, carcinogenic aerosols, and other chemical substances. The ozone standard applies only to devices that produce ozone as a waste product. The radon standards and guidelines apply only to buildings that are contaminated as a result of uranium-processing (e.g., by the use of mill tailings as landfill) and buildings that are on phosphate land in Florida.
Tables A-1 through A-8 list a number of U.S. outdoor air-quality and occupational standards and some relevant foreign standards. They are presented not as an exhaustive list of air-quality standards, but rather to impart perspective to the many allusions to standards throughout this report.
