Description:

Real-time measurement of polycyclic aromatic hydrocarbons (PAH) on fine particles was evaluated in a home with environmental tobacco smoke (ETS) as a source. he PAS 1000i PAH monitor (EcoChem Technologies, Inc., West Hills, CA) is based on photoelectric ionization of surface PAH, loss of photoelectrons, and subsequent measurement of the remaining positively charged particle in a filter electrometer. igarettes were smoked in the living room of a small house, with the time series of PAH concentrations logged with high time resolution using a Langan DataBear L15 data logger. espirable suspended particles (RSP) were monitored using the Model 8510 Piezobalance (TSI, Inc., St. Paul, MN), which measures fine particle concentrations with 2-min averaging periods. omparison of PAH and RSP concentrations from these experiments suggests: 1) the PAH concentrations for the two types of cigarettes -- a regular Marlboro filter cigarette and a University of Kentucky reference cigarette No. 2R1 -- were similar, but the RSP concentrations were different; (2) concentrations from the real-time PAH monitor were linearly related to RSP concentrations; (3) the slopes of the regression lines between PAH and RSP differed for the two types of cigarettes. he real-time PAH monitor appears to be a useful tool for evaluating mathematical models to predict the concentration time series in indoor microenvironments.
