This work presents a method for the measurement of Pb by linear sweep anodic stripping voltammetry on an Hg film electrode. The linear working range for Pb was up to 100 μgL-1, whilst the limit of detection was 19 ngL-1 (360 seconds accumulation time) and per cent residual standard deviation across 10 measurements was 0.98%. The method was applied to gunshot residues for the onsite monitoring of Pb at a public shooting range.
