摘要：

Traditional laboratory X-ray fluorescence (XRF) analysis has utilized sample preparation methods because the fixed nature of the instruments and absence of a surface probe precluded in-situ soil and sediment analysis. Currently, several field-portable XRF (FPXRF) instruments feature surface probes providing the option of in-situ soil and sediment analysis. In-situ FPXRF analysis can be a cost-effective near-real-time method to increase sampling densities due to the simplicity of the sample preparation. The following is a comprehensive statistical evaluation using current US EPA quality assurance guidelines for lead (Pb) data from a battery breakage site and zinc (Zn) and Pb data from a scrap metal site.
