A rapid and sensitive method for the determination of trimethyl‐lead in water and road dust is described. It is based on in situ ethylation of ionic methyl‐lead by sodium tetraethylborate and the extraction of the compound formed into hexane. The extract is gas‐chromatographed and the lead species determined by microwave‐induced plasma atomic emission spectrometry (MIP‐AES). The reaction conditions are optimized and the method is applied to the analysis of artificial rainwater and road dust in the framework of an international round‐robin exercise.
