摘要：

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.
