Abstract
The results of round 15 of the Environmental Lead Proficiency Analytical Testing (ELPAT) program were discussed. The ELPAT program was administered by the American Industrial Hygiene Association (AIHA) to evaluate and improve the performance of laboratories performing analyses associated with lead (7439921) abatement. Proficiency test samples for the participating laboratories were prepared by the Research Triangle Institute, an AIHA contractor, using paint chips, dust wipes, and soils. Four samples of each matrix were prepared. The samples were sent out each calendar quarter (round). Laboratories were rated based upon their performance in the ELPAT program over the past year (four rounds) for each lead matrix: paint chips, soil, and dust wipes. A laboratory was rated as proficient if all four sample results for each matrix were reported and designated acceptable for the last two consecutive rounds or at least 75% of the results reported in the last four consecutive rounds were judged acceptable. A total of 412 laboratories were enrolled for round 15, the samples for which were sent out in May 1996; 375 laboratories (91%) submitted results. Flameless atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry were the major analytical methods used. Of the 367 laboratories that reported results for the four paint chip samples, 330 to 343 were judged acceptable, 278 to 302 of the 315 that reported results for the four soil samples were judged acceptable, and 306 to 322 of the 343 that reported results for the dust wipes were judged acceptable.
