AbstractProfile samples were collected from peat hummocks and hollows from 37 peatlands within a 100 km radius of the Horne copper smelter, to investigate the value of peat as an historical record of smelter metal emissions. Splits of 630 samples were digested with HNO3-HClO4 prior to analysis for smelterrelated (Cu, Pb, Zn) and non-smelter (Ni) elements. Twenty-four samples were subjected to a four-step sequential extraction analysis to identify the main metal residence sites. Peat age was constrained from 137Cs, bulk density, and vertical growth rate data. Concentrations of Cu, Pb, and Zn were relatively low in the uppermost 20 cm of the hummocks and increased markedly between depths of 20 and 45 cm. In the tallest hummocks, metal concentrations decreased again below 50 cm depths and, by 60 to 75 cm depth, reached values less than those in the uppermost 20 cm. This pattern was most pronounced within 25 km of the smelter but was still discernible in hummocks at distances of more than 60 km. A similar pattern of increased and decreased concentrations was found in hollows, but it was compressed over the uppermost 20 cm of the hollow peat sequence. In hummocks 10 km and more from the smelter, about 25% of the Cu and 75% of the Pb and Zn resided in the labile phases, whereas closest to the smelter, in the 7 km hummock, even larger amounts of these elements were labile. In contrast to the smelter-derived elements, Ni concentration in hummocks and hollows varied.
