Mobilisation of sediment-associated metals from historical Pb working sites on the River Sheaf, Sheffield, UK

Hutchinson, SM; Rothwell, JJ

Abstract

Spatial and temporal patterns of metal mobilisation from former water-powered, Pb working sites in a suburban area of Sheffield (UK) were
investigated. Twelve time-integrated mass flux samplers were strategically deployed over two contrasting campaign periods (summer and
winter). Suspended sediment samples were characterised magnetically and subjected to metal analysis. Metal levels in the upper River Sheaf
showed a marked spatial and temporal variability. Pb concentrations in particular were relatively high (maximum 2132 mg kg-1). Their distribution
tended to reflect the historical contamination of the valley by 17th to 19th century industry, especially during summer high discharge
conditions. The mean suspended sediment Pb concentration (803 mg kg-1) exceeds contamination guidelines. It is unclear whether ground
remediation of one of the seven floodplain sites in the catchment has been successful. The river is still affected by the legacy of at least two
other Pb working sites.
