PERSONAL MONITORING-SYSTEM FOR MEASURING ENVIRONMENTAL TOBACCO-SMOKE EXPOSURE

A monitoring system, calibration system and bar code-based, computer s ample tracking system For measuring personal exposures to environmenta l tobacco smoke (ETS) are described. The monitoring system collects bo th vapor and particulate phase ETS analytes on a sorbent tube and filt er, respectively, using a single sampling pump. Several battery pack c onfigurations are described which enable continuous sampling times of 16, 28 and 48 h. Detailed methodologies are presented for determining nicotine, 5-ethenylpyridine and myosmine in the vapor phase and respir able suspended particles, solanesol, scopoletin, UVPM and FPM in the p articulate phase. Experiments conducted in a controlled-environment te st chamber show that all analytes increase linearly with the number of cigarettes smoked. In addition, 3-ethenylpyridine is shown to track c losely the vapor phase of ETS (as measured by CO and FID) while nicoti ne poorly estimates the vapor phase. These data support previously pub lished findings that 3-ethenylpyridine is superior to nicotine as an E TS vapor phase marker.
