The aim of this study was to investigate the relation between two toxic volatile organic compounds, 1,3-butadiene and benzene, a commonly used indicator vehicle exhaust fumes, NO2. This see if NO2 can be indicate personal exposure carcinogenic substances or at least estimate ambient levels measured stationary point. During winter 2001, 40 randomly selected persons living in City Umeå (in north Sweden) were recruited study. Personal measurements 1,3-butadiene, benzene performed for one week, repeated 20 participants. Additional information gathered using diary kept by each participant. same time period weekly urban background station street city centre. results from showed negligible association with (r = 0.06) as well 0.10), while correlation coefficient high significant 0.67). In contrast measurements, strong relations both within in-between station. supports potential streets air, weak found do not support use an exposure.
