Potential Methods for Measuring and Detecting Lead in Existing Paint Films: ALiterature Review

摘要

Recent legislation required the U.S. Department of Housing and Urban Development(HUD) to establish procedures to eliminate, as far as practicable, the hazards of lead-based paint poisoning in any existing HUD-controlled housing. Thus, HUD promulgated a regulation which requires abatement to eliminate lead-based paint poisoning hazards in housing in which the concentration of lead in paint equals or exceeds 1 mg/sq cm. The legislation also required HUD to review test methods for measuring lead in paint. The National Institute of Standards and Technology was tasked with the requirement. The review is the subject of the report. Test methods were evaluated based on the following criteria: safety, reliability, accuracy, precision, detection limit, ease of use, and technical skill required to make a measurement, nondestructive, and cost of an analysis. Methods were separated into two categories: field test methods and laboratory test methods. The laboratory test methods were also separated by whether the sample needed to be in solution or could be analyzed as a solid. None of the potential test methods met all of the desired criteria.
