Abstract：Atmospheric PM2.5 was collected from Wuzhi Mountain Background in Hainan from January~October, 2011, the 16 types of PAHs priority controlled by US EPA were analyzed by GC/MS. The results suggested that all 16 priority PAHs were detected in Wuzhi Mountain Background, the total PAHs concentration ranged from 1.773 to 4.612ng/m3, the average concentration was 3.101 ng/m3±0.720ng/m3 with the highest concentration of Flu and Py. The 4~6 rings PAHs with higher M.W. and lower volatility were the dominant components in Wuzhi Mountain Background, and the 4 rings PAHs had the highest concentration as 1.190ng/m3, which contained 38% of the total PAHs concentration. According to the diagnostic ratios of PAHs from typical sources, biomass burning was the dominant source of PAHs in atmospheric PM2.5 in Wuzhi Mountain Background. The total TEQ concentration was 0.364ng/m3, which was lower than the controlled BaP by China and WHO, suggested that the pollution in Wuzhi Mountain was at a lower level.
