Considering the productive potential of rawpropolis in Argentina and its therapeutic properties, it is necessary to verify the existence of contaminants. Electrochemical techniques are a good option to carry out the determination of pollutants, especially lead in propolis. The voltammetric technique presents the analytical advantages of high degree of accuracy, precision, sensitivity and selectivity. Moreover,measurements are carried out in a rapid analysis time and the instrumentation used is less expensive than spectrometric techniques. In the last years, bismuth-based electrodes have increasingly become a very attractive system for the determination of trace metals through anodic stripping voltammetry (ASV) in a wide variety of samples of different origins. Nowadays, the use of bismuth-coated electrode is an alternative to mercury in electroanalysis due its low toxicity. Several analytical methods are available to analyze the level of lead in water samples employing bismuth electrodes. However, we have not found any report about their application to complex samples as propolis. with dithizone in chloroform forming a lead–dithizone complex that absorbs at 510 nm. This method uses a liquid–liquid extraction and large amounts of hazardous organic solvents. Moreover, it has the disadvantage of being laborious, time consuming procedure and numerous mistakes can occur during this stage.
