Development of an electroanalytical method for the determination of lead in Argentina raw propolis based on bismuth electrodes

►Argentina raw propolis meets basic requirements for export. ►Argentina law establishes the maximum lead level in raw propolis of 2.0 mg kg− 1. ►A square wave anodic stripping voltammetry method to determine lead was developed. ►A bismuth electrode prepared in situ on modified glassy carbon electrodes was used. ►This method is a good alternative for the quality control of Argentina raw propolis.
