Deposition fluxes of PCDD/Fs in a reservoir system in northern Taiwan
► Atmospheric settling and sedimentary deposition was conducted in the reservoir investigated. ► The higher atmospheric PCDD/F deposition was observed during the long-range transport events. ► PCDD/F accumulation rate in the sediments was significantly higher to atmospheric deposition. ► 90% PCDD/Fs...

| description | ► Atmospheric settling and sedimentary deposition was conducted in the reservoir investigated. ► The higher atmospheric PCDD/F deposition was observed during the long-range transport events. ► PCDD/F accumulation rate in the sediments was significantly higher to atmospheric deposition. ► 90% PCDD/Fs input of reservoir were contributed by catchment erosion during intensive typhoon periods.
In this study, polychlorinated dibenzo-
p-dioxin and dibenzofuran (PCDD/F) concentrations and depositions in ambient air, water column and sediment were measured at a coupled reservoir-watershed system in northern Taiwan. The atmospheric PCDD/F concentration measured in the vicinity of the reservoir ranged from 4.9 to 39

During summer, when atmospheric deposition is lower, consecutive tropical cyclones (typhoons) bring heavy rainfall that enhances soil erosion and creates turbidity-driven intermediate flow.

Based on the mass balance between the measurements of atmospheric deposition and sinking particles in water column, around 54–74% of PCDD/F inputs into the reservoir were contributed by the catchment erosion during normal period. However, the PCDD/F input contributed by the enhanced catchment erosion significantly increased to 90% during intensive typhoon events. |
