Sediment–Water Interactions in an Eroded and Heavy Metal Contaminated Peatland Catchment, Southern Pennines, UK

Abstract: Atmospherically deposited lead in the upper layer of the heavily eroded peatlands of the Peak District, southern Pennines, UK, reaches concentrations in excess of 1,000 mg kg −1 . Erosion of the upper peat layer in this region is releasing lead, associated with eroded peat particles, into the fluvial system. Understanding the process mechanisms that control dissolved lead concentrations in contaminated peatland streams is vital for understanding lead cycling and transport in peatland streams. Many headwater st… Show more

“…Low total contents of lead within the peat horizons (nH) amounted to a mean of solely 388 mg kg −1 (Table 1) can be explained by limited amounts of mobilised lead in these horizons due to very low pH values and a subsequent transfer in upper or lower sediment layers (e.g. Rothwell et al 2006Rothwell et al , 2007. Detected fulvic acids are indicative for a good solubility of lead and abolish the adsorptive effect of the organic substance (e.g.…”
