Screening Procedures for Detecting Lead in Existing Paint Films: A LiteratureReview

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 first phase of the task, the subject of the report, was to review the literature for screening methods for measuring or detecting lead in paint. To facilitate the review, criteria were developed for potential test methods. A test method must be: capable of detecting lead concentrations of 1 mg/sq cm but not concentrations less than 0.06%, non-hazardous, suitable for use as a nondestructive field method suitable for use by non-technical personnel, and sufficiently reliable and precise. No method reported in the reviewed literature met all of the requirements.
