Heavy metal transport and storage in an upland catchment: a case study from the River West Allen, Northumberland.

Abstract:

Relationships between concentrations of Cd, Cu, Fe, Pb, Zn in mosses, and aspects of sediment supply and transport are examined in an active gravel-bed stream whose catchment is extensively mineralized by lead and zinc ores. General trends in heavy metal concentrations downriver in moss and sediments are associated with the distribution of mines, spoil heaps and mineralization zones which act as local sources of metal supply. A model for heavy metal transport and storage is evaluated using path analysis. Particulate transport is the dominant mode of movement for all heavy metals analysed in this study, although small quantities of Cd, Cu, and Zn are transported in solution. -from Authors
