| Abstract: | Polycyclic aromatic hydrocarbons(PAHs) of 16 types were measured in sediment from Xidayang Reservoir,Hebei Province,and the possible sources and potential risk assessment also had been analyzed.Total PAHs concentrations varied from 422.36 to 1052.90ng/g in surface sediment,and increased continuously from reservoir upstream to the front areas of the reservoir dam.The total PAHs concentrations ranged from 388.81 to 1205.56ng/g in a sediment profile,and increased continuously from the bottom(20cm under the sur... |
