Abstract
A nonrandom group of 40 volunteers participated in a study to determine the level of correlation between three methods of sampling for volatile organic compounds (VOC): organic vapor badges, charcoal tubes, and blood VOC levels. Each of 40 volunteers provided blood samples for analysis. Nineteen subjects wore organic vapor badges for at least 5 hours, and 24 subjects provided personal breathing zone samples captured on charcoal tubes. Subjects were exposed to gasoline (8006619) fumes while working around automobiles or as city commuters. The highest level of correlation with blood VOC levels was observed with the organic vapor badges. Methyl-tert- butyl-ether (1634044) (MTBE) was observed in the blood of 15 of 19 subjects. The organic vapor cartridges detected MTBE in nine of 15 subjects, while the charcoal tubes detect MTBE in one of 13 subjects. The nine subjects with detectable MTBE levels (using badges) were either automotive mechanics or gasoline pumpers. Toluene (108883) and o-xylene (95476) were detected in the blood of all participants. The organic vapor badges detected toluene and o- xylene in 18 of 19 subjects, while the charcoal tube detected toluene and o-xylene in nine of 14 subjects. Organic vapor badges were also more sensitive in detecting low levels of VOCs compared to charcoal tubes. The authors suggest that organic vapor badges may be a convenient means of determining exposure levels of VOCs.
