Description:
The paper gives results of a comparison of methods for measuring concentrations of semivolatile particulate matter (PM) from indoor-environment, small, combustion sources. Particle concentration measurements were compared for methods using filters and a small electrostatic precipitator (ESP). Particle size distributions were measured using an electrical low-pressure impactor. Semivolatile PM produced from cigarette and incense smoke was compared with a relatively nonvolatile aerosol produced from polyalphaolefin oil. Results showed that semivolatile PM concentrations measured using the ESP method were significantly higher than those measured using the filter method. The ESP method was shown to be a more effective means of measuring semivolatile PM under the test conditions.
