SUMMARY. The concentrations of trace metals in filtered and unfiltered lake water were measured using anodic stripping voltammetry, before and after digestion by ultra‐violet irradiation, and by atomic absorption spectroscopy with electrothermal atomization. Total soluble components were estimated to be: zinc, 2.1 μg 1 −1 ; cadmium, <0.05 μg l −1 ; lead, <(0.1 μg l −1 and copper, 0.3 μg 1 −1 . Atomic absorption spectrophotometric results and u.v.‐digested, anodic stripping voltammetric results were in good agreement. All measurable zinc was electrochemically labile whereas copper above the detection limit of 0.09 μg l −1 was electrochemically inert.
