ABSTRACT
Early research efforts related to indoor air quality concentrated on several criteria pollutants (CO, NO2, particulates) and several uniquely indoor pollutants (radon, formaldehyde, asbestos). More recently, researchers have begun to investigate indoor air quality impacts of noncriteria pollutants including volatile organics. Several studies have identified and quantitated large numbers of volatile organics in the indoor environment at concentrations ranging from 100 ppt in a new unoccupied hospital to 10-20 ppb in occupied offices [1,2], homes [3,4,5], and schools [6]. In several of these studies, specific organics were related to building materials or products present in the indoor environment [2,3,4,6].
