摘要：

The US Environmental Protection Agency's Environmental Response Team (US EPA/ERT) has extensively used held-portable X-ray fluorescence (FPXRF) instruments for analyzing metals in soils and sediments at hazardous waste sites nationwide. The US EPA/ERT has used the Outokumpu Electronics Inc. (OEI) model X-MET 880 and the Spectrace Instruments model 9000 FPXRF analyzers. Instrument calibration methods, precision and detection limits are discussed. Both in-situ and prepared soil analysis are described. A statistical comparison of slopes (regression coefficients) is presented comparing AA/in-situ FPXRF and AA/prepared sample FPXRF regression results for data from a battery breakage and scrap metal site. The instruments' analytical capabilities are demonstrated by measurements of chemically analyzed samples from a variety of soil and waste matrices. Additionally, the US EPA's Quality Assurance/Quality Control (QA/QC) procedures for FPXRF analysis of soil and sediment samples is presented.
