Sediments are not static but subjected to diagenesis processes and release chemicals to the overlyingwater.Therefore,they should be regarded as a third endmember in estuarine mixing processes.Inorder to determined the benthic fluxes across the sediment-water interface along a salinity gradient,to assess the influence of sedimentary input on the mixing behavior of solutes (DIC,NH3-N,NOx-N,SRP and Mn) in Jiulong River Estuary and to identify the dominant processes modulating the benthicinput,a 224Ra/228Th disequilibrium approach was applied.The sediment act as source for DIC,NH3-N,SRP and Mn,respectively,while they uptake NOx-N.
