The mutagenicity of indoor air particulate matter has been measured in a pilot field study of homes in Columbus, Ohio, during the 1984 winter. The study was conducted in eight all natural gas homes and two all electric homes. Particulate matter and semi-volatile organic compounds were collected indoors using a medium volume sampler. A micro-forward mutation bioassay employing Salmonella typhimurium strain TM 677 was used to quantify the mutagenicity in solvent extracts of microgram quantities of indoor air particles. The mutagenicity was quantified in terms of both mutation frequency per mg of organic matter extracted and per cubic meter of air sampled. The combustion source variables explored in this study included woodburning in fireplaces and cigarette smoking. Homes in which cigarette smoking occurred had the highest concentrations of mutagenicity per cubic meter of air. (Copyright (c) Atmospheric Environment Vol. 21, No. 2, pp. 443-449, 1987.)
