| 摘 要： | Submarine groundwater discharge(SGD) plays a major role as a conveyor of metals to coastal waters. However,the seasonal change of metal fluxes derived through SGD is unclear. Here, we evaluated the behaviours and fluxes of trace metals(Mn, Fe, Ba, Pb, U, Cr, Zn, Cu) in an estuary under different seasonal conditions. The behaviours of trace metals revealed that SGD was the source of Mn(3.51 mmol/(m2·d)), Fe(0.174 mmol/(m2·d)) and Ba(0.024 mmol/(m2·d)), but the Cu ...
