The sediment analyses were carried out by automatic flow coulometry with a much higher flow rate than in classical stripping voltammetry. The concentrations of the metal ions were in the mg dm−3 range and lower in the calibrationless mode. The measured concentrations of Cd were 0.022 – 22.60 mg kg−1 and those of Pb 12.93 – 59.04 mg kg−1 in the water reservoirs.
