Major and trace element analytical methods of the National Status and Trends Program : Update 2000-2006

"Sample preparation and analysis methods have been developed and refined that allow the accurate and precise determination of major and trace elements in sediment and biological tissue samples. Sample preparation emphasizes homogenization and total digestion steps that minimize contamination. Analyses utilize atomic spectroscopy techniques, including a full suite of quality assurance and quality control samples, with an emphasis on certified reference materials, in order to produce reliable data. These methods allow measurement of both background and elevated concentrations in samples collected as part of NOAA's National Status and Trends Program."--p. 2 of text. K.L.
