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.
