Trace metals in waters and sediments of the river tawe, South Wales, in relation to local sources

The concentrations and distribution of cadmium, cooper, nickel, lead and zinc have been studied in a small river and its estuary in South Wales. The river drains the Lower Swansea Valley, an area severely contaminated by smelting and other industries over the last 250 years. The high trace metal lev...

Description
Summary:The concentrations and distribution of cadmium, cooper, nickel, lead and zinc have been studied in a small river and its estuary in South Wales. The river drains the Lower Swansea Valley, an area severely contaminated by smelting and other industries over the last 250 years. The high trace metal levels found in both waters and sediments result from weathering and erosion of the waste material left by those industries. As a result, the River Tawe appears to be a major source of certain metals to coastal waters of the northern Bristol Channel between Caldy Island and Porthcawl and contributes to elevated metal levels in Swansea Bay.
