摘要：

A chlor-alkali plant proved to the most important source of mercury but its contribution has not yet been disentangled from those originating at a pyrite roasting facility and a PVC factory operating in the same industrial park. Sewage discharges from the bankside communities are the other significant point sources of Hg. Concentrations of Hg in the superficial sediments ranged from 850 mgkg** minus **1, near the chlor-alkali sewer outlet, to 0. 05 mgkg** minus **1 in the intertidal sands of the coastal beaches. Sewage affected sediments have concentrations of Hg in the range of 1 to 2 mgkg** minus **1. Bioaccumulation of Hg in fish tissues shows the usual dependence on species, territoriality, feeding habits and size. Concentrations as high as 25 mgkg** minus **1 fresh weight have been observed but the average values do not exceed the EEC quality objective of 0. 3 mgkg** minus **1.
