As part of a broader investigation into recent environmental change on Svalbard, the inorganic geochemical record of six lake-sediment cores was analysed. The major temporal trends in sediment elemental composition are driven by variations in two contrasting sediment components, both derived from catchment soils: (1) mineral matter, and (2) soil organic matter (SOM), enriched in Fe and Mn oxides and heavy metals.Two environmental impacts are recorded in most or all of the lake sediment sequences. An up-core increase in organic matter can be partly attributed to diagenetic effects, but also requires an enhanced supply of SOM relative to mineral matter. In addition, the central and southern sites all show a ca. 1970 event characterised by an enhanced mineral matter accumulation rate. This requires either an enhanced allochthonous supply or an enhanced mobilisation of littoral sediments. In either case a regional-scale driving force, such as a shift in climate, is required.At five of the lakes the sediment heavy metal concentration profiles can be explained entirely by natural factors. However, at Tenndammen (U), situated close to the Svalbard's largest settlement at Longyearbyen, possible anthropogenic Pb enrichment is found.Comparison of observed and expected heavy metal profiles (based on Greenland ice-core data) shows that the lakes are generally too insensitive to have recorded a long-transported heavy metal pollution signal.

“…Copper concentrations appear highest in Penrhyn. Many lakes, both pristine and with sewage input, have profiles with metals increasing over the last 130 years, especially in recent times (Hamilton-Taylor, 1979;Haworth and Lishman, 1991). As in these lakes, the Zn/Cu ratio is ca 3-5, possibly due to atmospheric pollution from coal combustion, so that the increases at 15cm and 25cm in Dinam and Penrhyn could be contemporaneous.…”

“…The density (p) of the dried sediment (1.8 g cm-3) and its metal concentrations are from a study undertaken at the deepest point in the south basin (HamiltonTaylor 1979)-the same location used for sampling surface lake water in the present work. The sediment accumulation rates given in Table 5 are based on the mean metal concentrations (C) at a depth between 2 and 10 cm, immediately below the surface oxide floc associated with localized redox cycling (Hamilton-Taylor 1979). Thus, the accumulation rates were determined by a relationship of the form sed.…”

“…The scarcity of systematic trace-metal studies in lakes compared to the oceans (Murray 1987;Sigg 1985Sigg , 1987) is therefore surprising. This paper represents part of an ongoing study of the origins and cycling of trace metals, in particular Cu, Pb, and Zn, in Windermere (Hamilton-Taylor 1979;Hamilton-Taylor et al 1984;Reynolds 1986). The aims are to determine the nature of and to quantify the major inputs (rivers, direct atmospheric deposition, and direct sewage Rcknowledgmenh Work supported by the Natural Environment Research Council (grant GR3/4029).…”

Dissolved (qO.45 pm) and particulate concentrations of Fe, Mn, Al, Cu, Pb, and Zn were measured at intervals of 2-6 weeks in rivers, sewage effluents, atmospheric deposition, and surface lake waters within the Windermere (U.K.) catchment over a 2-yr period. Factor analysis revealed a number of geochemical associations: a large proportion of the particulate Fe, Al, Pb, and Cu appears to be associated with detrital mineral and organic material in the rivers, sewage effluents, and atmospheric deposition; redox processes, probably occurring higher in the catchment, have an appreciable influence on the riverine concentrations of dissolved Fe and Mn, particulate Mn, and to a lesser extent particulate Fe and Zn; pollution terms account for most of the variance of dissolved Fe, Cu, Pb, and Zn, and particulate Cu, Pb, and Zn in the sewage effluent and atmospheric deposition data sets, respectively; and an association in the rivers of dissolved Al and Zn concentrations with discharge is probably related to catchment soil processes.Mass balances were determined for the metals, including a detailed assessment of the errors involved. An inbalance was apparent between the inputs and outputs (flushing and sedimentation), probably due to underestimation of particulate loads in the rivers. Fe, Mn, and Al were predominantly (> 90%) supplied by rivers, while Cu, Pb, and Zn received significant inputs from direct atmospheric deposition and sewage discharges. The residence times of the dissolved metals in Windermere were in the order: Cu > Zn > Pb * Fe, a sequence consistent with observations in various alpine lakes. More than 50% of the dissolved inputs of each metal was retained in the lake, except for Cu, which appeared to show a small net loss from the lake.
