Personal N02 Exposures of Taxì Drivers

Personal NO~ expousre and time activity patterns were measured during March, 1991 fQr 46 taxi drivers in the Seoul area. Badge-type personal samplers were worn for 24 hours by taxidriversfor monitoring personal expousre to N02• A standard respiratory questionnalre was administered and pulmonary function test was per formed using a protable spirometry. The mean concentrations of personal N02 expousres of taxi drivers were O.55ppm. Personal N02 exposures of taxi drivers were seemed to be higher in longer period of driving, smokers, and use of LP gas in homes. Prevalence rate of respiratory symptoms and the level of pulmo!lary function(FEVLO and FVC) seemed to be related to higher personal N02 concentrations. It is concluded that persoanl N02 expousres of taxi drivers are probably affected by indoor NOz levels of a taxi and their common activlties.
