Introduction: Recent studies indicate that the released caused by traffic jams to increase mortality and hospitalization of patients as a result of cardiovascular disease This study tries to investigate the density of PM2.5 dust particles to which taxi drivers are exposed in Bojnord. Methods: In this study, the density of PM2.5 dust particles was measured for 677 taxi drivers in 12 main routes of Bojnord in 10 months using a sampling and direct decomposing instrument namely, Micro Dust Pro, to getter with a calibrated personal pump with debit 3.5 lit/min. Results: The results of this study showed that the mean of exposure of drivers with PM2.5, is 108.08 ± 229.64 μgm-3. The minimum exposure for all drivers is 62.37± 79.95 μgm-3 and the highest exposure is 151.06± 96.396 μgm-3.Environmental factors also affected the driver exposure level, with the highest exposure at wind speeds (12ms-1, 134 ± 311.9 μgm-3), wind direction 90-180 (144.8 ± 205 μgm-3) In relative humidity, 81-100% (119 ± 250.9 μgm-3), in cloudy weather (151.7 ± 297.1 μgm-3), and kind of route (on the Shahid street to the airport) (151 ± 370 μgm-3). Results: The results of this study showed that the mean of exposure of drivers with PM2.5, is 108.08 ± 229.64 μgm-3.
