چکیده انگلیسی
A total of 150 samples were collected from 25 sites in the Yellow River of Henan Province during 2014 to demonstrate the impact of suspended sediment (SS) load on the behavior of semi-volatile organic compounds (SVOCs) in the Yellow River. The average concentrations of SS ranged from <0.01â¯g/L to 1.7â¯g/L and the total loading/removal of SS was 108â¯Mt in the Henan section of the Yellow River. The sixteen polycyclic aromatic hydrocarbons (PAHs) were detected with concentrations of 23-370â¯ng/L in the dissolved phase and 36-3700â¯ng/g dw in the particulate phase, respectively. The concentrations of â16PAHs (sum of PAHs in the dissolved and particulate phase) along the river flow showed a decreasing trend and then an increasingly varied SS concentration. In the SS-abundant section, PAHs were released from the particle phase to the dissolved phase. Based on the mass balance of water and SS, 43% of the total load of PAHs is ascribed to the scouring processes, indicating that PAHs release from river-bed soil to the Yellow River is significant.
