NIST Intercomparison Exercise Program for Organic Contaminants in the Marine Environment: Description and Results of the 2000 Organic Intercomparison Exercises

摘要

In support of marine monitoring measurement programs, the National Institute of Standards and Technology (NIST) conducts yearly interlaboratory comparison exercises to provide one mechanism for participating laboratories and monitoring programs to evaluate the quality and comparability of their performance in measuring selected organic contaminants in environmental samples. In this report, results of the year 2000 exercises of the NIST Intercomparison Exercise Program for Organic Contaminants in the Marine Environment are described, in which selected polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyl (PCB) congeners and chlorinated pesticides were determined in Mussel Tissue X and in Marine Sediment X exercise materials. The analytical methods used by each participating laboratory in this performance-based program are also summarized.
