National status and trends program for marine environmental quality. Quality assurance project: Trace organic intercomparison exercise results 1986-1990. Technical memo
The National Oceanic and Atmospheric Administration (NOAA) National Status and Trends (NS&T) Program determines the current status and any changes over time of the environmental health of the estuarine and coastal waters. Concentrations of organic and inorganic contaminants are determined in mollusks, bottom-dwelling fish and sediments collected along the coast of the U.S. The quality of the analytical data generated by the NS&T Program is overseen by its quality assurance (QA) Project component, that is designed to document sampling protocols, analytical procedures, and laboratory performance, and to reduce intralaboratory and interlaboratory variation. NS&T does not specify analytical methodology. All NS&T laboratories are required to participate in yearly intercomparison exercises. The results of the intercomparison exercises are described and discussed.
