Indoor air pollution in residences, offices, public access buildings, and the like may be as important a factor to public health as pollution in the outdoors and in indoor-industrial environments. The advent of energy-conservation measures, new technologies, and new materials in buildings may exacerbate the potential indoor air pollution problem. In addition to others, unvented gas appliances are perceived to be sources of indoor nitric oxide (NO) and nitrogen dioxide (NO2). Chamber experiments were performed to measure emission rates of NO, NO2, and CO for range-top burners, range ovens, pilot lights, gas dryers, gas space heaters, and cigarettes. The values evaluated establish the range of emission rates for these constituents under well-controlled conditions. Emissions of particulate matter, formaldehyde, polynuclear aromatic hydrocarbons, and volatile organic compounds were also measured and found to be low compared to NOx and CO. Factors that impact on the emission rates from unvented gas appliances include appliance type, primary aeration level, relative humidity, and variable fuel rate (firing rate). Chamber experiments confirm that the presence of indoor surfaces (fabric, carpet, etc.) reduces the indoor NO2 concentrations.
