摘要

Port Pirie is the site of the largest lead smelter in the world, depositing 250 t of zinc, and 100 to lead annually into Spencer Gulf. Barker Inlet is adjacent to metropoli- tan Adelaide, and receives unknown quantities of urban and industrial discharges. Both areas are sites of major commercial and recreational fisheries, contained within delicately balanced marine wetland ecosystems, compris- ing large areas of mangrove and seagrass habitats.
