| 摘要 | In this study, the authors assessed occupational exposure to PM2.5 among 47 highway toll station workers in Taipei, Taiwan. The subjects were monitored for 10 days to assess integrated 8-hr fine particulate matter (PM2.5) breathing zone concentration. Researchers constructed a microenvironment-time-concentration matrix and applied direct and indirect approaches to assess cumulative exposure. Mean PM2.5 concentration for workers in the truck and bus lanes was 308 μg/m5 (SD = 115.5 μg/m3), substantially higher compared with cash-payment car lanes (mean 115, SD = 41.8, p < 0.001) and ticket-payment car lanes (mean 109, SD = 48.7, p < 0.001). Concentration per vehicle in the truck and bus lanes was 6.4 and 3.7 times higher, respectively, than that of ticket- or cash-payment car lanes. Mean cumulative exposure for the 10-day period was 4,900-13,407 μg/m3 · hr, with a mean of 8,019 μg/m3 · hr (SD = 2,375.3). Indirect and direct concentrations were strongly correlated (r2 = .61, F(1, 125); p = 0.000). The results of this study show that personal exposure to PM2.5 can be reliably estimated using indirect approaches. |
