Potential impact of deliberately introduced ozone on indoor air quality

Population subsets whose behavior leads to unusually large exposures to toxicants are of interest to exposure assessors. Despite U.S. Food and Drug Administration (FDA) restriction since 1974, ozone generating devices continue to be marketed in the U.S. for indoor use. Promotional materials cite a host of alleged benefits to indoor environmental quality. Generation rates cited in sales literature are used here to estimate indoor air ozone concentrations that could result from use of such equipment. Predictions exceed relevant air quality standards, in some cases by a substantial margin. Limited available experimental measurements support this finding.
