Vertical Distributions of Some Trace Metals in Lake Nurume, Antarctica
The concentration of some trace metals (Fe, Mn, Cu, Zn, Pb, Cd) in Lake Nurume was measured vertically. The concentration of trace metals in surface water decreases with increasing depth to the intermediate water layer. This fact may be ascribed to snow melt added to the surface water. The water lay...
