Abstract

Mine waters and tailings are key inputs to riverine metal(loid) transport to the coast. However, coastal areas also face local contaminant pressures, e.g. active industries and abandoned landfill sites. Annual riverine metal(loid) flux data were assessed alongside respective fluxes from coastal industries and legacy landfills along the NorthEast England coastline to quantify relative contaminant contribution. The majority of each contaminant flux (56-97%) entered the sea via riverine transport from inland orefields. However, coastal landfills contributed non-trivial fluxes of some contaminants (<93 t/yr Pb, <38 t/yr Ni, <17 t/yr As), indicating that inland management alone may not sufficiently remediate coastal waters.
