摘要：

The lead content of 12 wine samples was measured by inductively coupled plasma-mass spectrometry using the methods of standard addition and isotopic dilution analysis. An additional wine sample was analysed by external calibration, standard addition and isotopic dilution analysis. The lead content of the wine samples was in the range 30-150 ng ml-1 and good agreement between the different techniques was observed. Analysis of lead isotope ratios revealed significant differences between Australian and European wines, reflecting the different isotopic composition of Australian lead. © 1990 Taylor & Francis Group, LLC.
