Description :
A mass balance model of the main Pb stores and fluxes for a typical organic-rich upland catchment in the Peak District, has been produced. The model, based on the Howden reservoir catchment, reveals that the majority of Pb in the catchment is stored within the soil. Soil Pb levels are extremely high and can only be explained as the result of centuries of atmospheric Pb deposition from surrounding urban-industrial conurbations, and mining and smelting activity within the Peak District National Park. Future change in climate or deposition chemistry could transform catchment soils into a significant source of Pb to the aquatic environment and water supply.
