The paper will describe a study conducted in the Washington, D.C., area during the winter of 1982-83 for the purpose of measuring the distribution of carbon monoxide (CO) exposures of a representative population of the area. The population distributions were determined by direct measurement of CO with personal exposure monitors (PEM) through the use of statistical inference from a statistically drawn sample. The study also provided data (through the use of individual diaries) to determine exposure to CO as a function of concentrations within significant microenvironments (e.g., home, in transit, work, leisure) and individual activity patterns. Breath samples were also collected from sample individuals. The population of inference for the study was non-smoking adults (age 18-70) in the D.C. area which was estimated to include about 1.22 million individuals. The actual number of individuals sampled with usable CO data was 712.
