O-322 Assessing exposure to diesel particulate matter of truck drivers and streetside vendors in a heavily industrialised city in India

摘要: ObjectivesThe present study aims to examine the variability in fine PM and DPM exposures near a coal-haul road and city traffic road in a mining-dominated city in India to further estimate long-term exposure of truck drivers and street vendors to DPM.MethodPM2. 5 was measured during peak-and off-peak traffic hours over two weeks near a coal-haul road and a mixed-fleet city road near an active opencast coal mine in Eastern Maharashtra, India. Collected PM2. 5 samples were analysed for elemental and organic carbon (EC-OC), a surrogate of DPM, using thermo-gravimetric analysis along with estimation of potential annual and cumulative life-term exposure using job history information.
