NIST/NOAA NS and T/EPA EMAP Intercomparison Exercise Program for Organic211 Contaminants in the Marine Environment: Description and Results of 1997 Organic 211 Intercomparison Exercises. National Status and Trends Program for Marine 211 Environmental Qual

摘要

In support of marine monitoring measurement programs, NIST, in cooperation with211u001ethe NOAA National Status and Trends Program (NS&T), and the EPA Environmental 211u001eMonitoring and Assessment Program (EMAP), conducts yearly interlaboratory 211u001ecomparison exercises to provide one mechanism for participating 211u001elaboratories/monitoring programs to evaluate the quality and comparability of 211u001etheir performance in measuring selected organic contaminates in environmental 211u001esamples. In the report, results of the 1997 exercises of the NIST/NOAA NS&T/EPA 211u001eEMAP Intercomparison Exercise Program for Organic Contaminants in the Marine 211u001eEnvironment are described in which selected polychlorinated biphenyl (PCB) 211u001econgeners, chlorinated pesticides, and polycyclic aromatic hydrocarbons (PAH) 211u001ewere determined in Mussel Tissue Homogenate VIII and Marine Sediment VII exercise 211u001ematerials. The analytical methods used by each participating laboratory in this 211u001eperformance-based program are summarized.
