Performance Evaluations of Measurement Methods Used for Lead-Based Paint Contaminated Media: Current Status

Source

Evaluations of the performance of methods used to measure lead in paint and in paint-contaminated medias are being conducted by EPA's Atmospheric Research and Exposure Assessment Laboratory as part of an ongoing program to reduce the risks to lead exposures. The objectives of the program are (1) to improve the reliability of the measurements made in connection with soil, dust and paint abatement programs and (2) to reduce costs. Performance characteristics determined include bias, precision, interferences, working range, and throughput. Methods under evaluation include (1) the laboratory-based methods of atomic absorption, inductively-coupled plasma atomic emission, and X-ray fluorescence spectrometries and (2) the field-based methods of portable X-ray fluorescence spectrometry and test kits. Their performances were evaluated using, when available, Standard Reference Materials, method evaluation materials, and duplicate field samples. A review of the evaluations conducted to date is presented.
