Simulation of multi-media transfer and fate of naphthalene in Songhua River

Transfer and fate of naphthalene(PAHs) in multi-medium of Songhua River was studied.A level III fugacity model was applied to calculate the multi-interface transfer flux and concentration distribution of naphthalene in Songhua River under steady-state assumptions.The results indicated that soil was the largest storage of naphthalene,accounting for 40% of the total amount of residual.In air,water,soil and sediment,the concentrations of naphthalene were 3.58×10-6 μg·g-1,0.142 μg·L-1,5.28×10-4 μg·g-1 and 3.62×10-3 μg·g-1 respectively.The reliability of the model was verified by the coincidence of the calculated and the measured concentration in the same period.
