Abstract
A discussion was presented of the Proficiency Analytical Testing (PAT) Program. The PAT was described as a collaborative effort of several agencies to provide quality control reference samples to over 1400 occupational health and environmental laboratories in over 15 countries. It was noted that a mixture of three of four possible metals, and three of 15 possible organic solvents rotated for each round, and a total of 1352 laboratories submitted results on Round 114. Altogether, 91.1% of the 1404 laboratories evaluated were rated overall proficient in this round. A rating for the 1404 laboratories on performance over the last four rounds was included in this report. PAT Round 115 was released on October 1, 1993 and included as the organic solvents carbon-tetrachloride (56235), and trichloroethylene (79016). Metals included in this round were cadmium (7440439), lead (7439921), and zinc (7440666). Silica (14808607) also had a talc (14807966) and coal mine dust background. The asbestos (1332214) sample included was chrysotile (12001295).
