Abstract:The concentrations of 15 US EPA priority polycyclic aromatic hydrocarbons (PAHs) in 33 soil samples (0-10 cm layer) collected from various functional zones in Quanzhou city were analyzed by UPLC coupled with fluorescence detector. The sources of PAHs in the topsoils were apportioned using isomer ratios, and factor analysis and multiple linear regression. The ecological risks of PAHs in the topsoils were evaluated by using benzoa]pyrene toxic equivalents (TEQ(BaP)). Results showed that the total concentrations of PAHs in the soils ranged from 28.2 to 1432.3 microg x kg(-1), and 4 to 6 ring PAHs were the dominant compounds. The total concentrations of PAHs in soil samples from different functional zones decreased in the order of industrial areas > residential areas > scenic areas > agricultural fields. The PAHs in soils of Quanzhou city mainly originated from the combustion of coal, biomass fuels (straw), and liquid fossil fuels including gasoline and diesel. The TEQ(BaP) of the 15 PAHs ranged from 1.6 to 131.6 microg x kg(-1), with an average value of 38.9 microg x kg(-1). The total TEQ(BaP) of 10 PAHs in 34.6% of the soil samples exceeded the Dutch target reference value, suggesting that there are potential ecological risks in the topsoils in some areas of Quanzhou city.
