【 摘 要 】

Some workers had that exposure levels and health effects of polycyclic aromatic hydrocarbons (PAHs) analysed through personal urinary biomonitoring. Personal particulate samples were collected in highway workers' day shift working time. The spot urine samples were collected on each participant. In these samples, PAHs suggested by US-EPA were measured, and in the urine samples oxidative stress biomarker was analysed. The measured mean occupational exposed concentration of PM2.5 was 230.73 μgm-3, and the mean p-PAHs exposed concentration was 319.90 ngm-3 for the selected workers. Urinary concentrations of 8-OHdG increased by times following an 8-h work shift in participants. Significant positive associations were found between post-work shift urinary 8-OHdG and p-PAH concentrations. It's indicated that air exposures for PAHs originating from traffic emissions are important in increasing oxidative burdens in human body.
