Microenvironmental and total exposures to carbon monoxide for three population subgroups
This study was funded by the Electric Power Research Institute. The purpose was to investigate the practicality of using personal monitors to study relationships between microenvironmental and total exposures for certain population subgroups. Three population subgroups including housewives, office workers, and construction workers were selected, owing to differences in their potential exposures to CO. The study was conducted in the Washington DC area during the fall of 1982. Data was given for average CO exposures during travel, impact of start time and traffic level. Travel by car accounted for 70% of the travel time reported by study subjects. The gradient in exposures with traffic density was most consistent for trips in automobiles - 5 ppM for light traffic, 6.6 ppM for moderate traffic, and 10.6 ppM for heavy traffic. Among alternative transportation modes, the highest average exposures were incurred during travel by bus (6.9 ppM); the lowest average exposures were incurred for travel on foot (3.4 ppM), and by subway (2.9 ppM). By comparison, the EPA study measured average exposures of 5.1 ppM for trips by automobile and 2.4 ppM for walking, jogging, or bicycle. Through a combined microenvironmental and total exposure monitoring approach, information was simultaneously obtained concerning human activity patterns, microenvironmental characteristics, and the contribution of microenvironment types to the total exposure. 8 references, 6 tables.
