| Abstract | Three lake sediment cores were collected from Tatin Lake to evaluate the effects of changing limnological conditions on the distribution of trace metals in lake sediments. Two cores were taken from
sites where the hypolimnion was relatively oxygenated and the third from a sub-basin where distinctly anoxic conditions existed.
Sediments deposited in the relatively oxidizing environments have significant enrichments of Fe and Mn in the surface
sediments due to diagenetic cycling. Vertical trends in As, Co and Ni are similar to Fe and Mn, suggesting co-migration and enrichment of these elements during diagenesis. Concentrations of Cu, Cr, Mo, Sr, V and Zn are not significantly different in
the surface sediments compared to the background sediments.
Limnological variations are a significant factor in controlling the accumulation and preservation of trace metals in lake sediments. The usefulness of lake sediment data, whether for
exploration or environmental purposes, could be enhanced by evaluating it in the context of limnological information. |
