Abstract:Release of PAHs during the resuspension of sediment samples at Wuhan section of Yangtze River was determined using a particle entrainment simulator (PES). Quantitative relationships between applied shear and TSS concentrations, TOC in TSS, PAHs concentrations in TSS were set up by regression analysis, respectively. Combined these quantitative relationships with PAHs partition coefficients, mathematic models were developed to predict PAHs concentrations in overlying water during sediment resuspension. It was found that PAHs concentrations measured during simulated resuspension events were good in line with predictions by models. This indicated that mathematic models could provide good predictions of PAHs concentrations in overlying water during sediment resuspension under 0.2~0.5 N/m2.
