Abstract
The background and current status of the Environmental Lead Proficiency Analytical Testing (ELPAT) program was described. The evaluation of the individual laboratories in the ELPAT Program is based on consensus values from reference laboratories and is modeled after the evaluation procedures currently used in the Proficiency Analytical Testing Program. Laboratories are rated based upon performances in the ELPAT Program over the last year, four rounds each, for each lead (7439921) matrix. The ELPAT program conducted for Round Ten, February 1995, was described. Paint chips, soil and dust wipes were analyzed. The paint chips were prepared from a variety of sites including commercial lead abatement, building renovation, and demolition sites. Soil samples were taken from driplines around older houses in North Carolina and from industrial sites in Colorado and Louisiana. Dust wipes were prepared by gravimetrically loading filter paper with sterilized household and postabatement dust. Altogether, 368 laboratories were enrolled for Round Ten of the ELPAT Program, with 346 submitting results. The percentage of outliers for all analyses was under 8.0%. Sample digestion techniques and instrumental methods were categorized. Bias analysis for ELPAT Rounds Nine and Ten, lead reference materials, regulations, and upcoming ELPAT Round information were discussed.
