Abstract Two highly sensitive methods have been developed and applied to the monitoring of personal exposure to airborne mutagens and carcinogenic polycyclic aromatic hydrocarbons (PAH). The automatic method for PAH analysis consists of ultrasonic extraction and multicolumn HPLC/computer controlled spectrofluorometric detection, by which 7 PAHs in indoor and/or personal particulate samples were analyzed. Concentration of PAHs, e.g., benzo(a)pyrene, indoors increased remarkably by smoking in a poorly ventilated room. The second method, an ultra microsuspension forward mutation assay using Salmonella typhimurium TM677, is about 100 times more sensitive than the ordinary Ames mutation bioassay. Mutagenicity of airborne particles collected by personal sampling was determined by this method. Personal exposures to ETS were greatest for smokers, followed by passive smokers and lowest for nonsmokers suspension.
