Strontium and Lead Isotope Analyses for Determining the Geographic Origins of Grains

A rapid determination method of 87Sr/86Sr and Pb isotope (204Pb, 206Pb, 207Pb, and 208Pb) ratios was applied to determining the geographic origin of grain crops. This new method is more economical in terms of both time and cost compared to conventional methods. We used samples of barley (n = 321), r...

Description
Summary:A rapid determination method of 87Sr/86Sr and Pb isotope (204Pb, 206Pb, 207Pb, and 208Pb) ratios was applied to determining the geographic origin of grain crops. This new method is more economical in terms of both time and cost compared to conventional methods. We used samples of barley (n = 321), rice (n = 111), and wheat (n = 93) grown in various countries. 87Sr/86Sr versus Sr concentration plots for the barley and wheat showed differences between products from Australia and those from other countries. Graphs of the Pb isotope ratios, comprising 15 two-dimensional plots, gave rise to a particular distribution for each country of production. The presented method showed promise for determining the production countries of grains by using the isotope ratios of Sr and Pb.
