The National Institute of Standards and Technology has developed a new Standard Reference Material 1941, "Organics in Marine Sediment." In addition to the organic constituents, over 30 elements have been determined by instrumental neutron activation analysis and prompt-gamma activation analysis. The homogeneity of the material was investigated and relative standard deviations of single- element concentrations in 250-mg samples were found to be 1% or less with regard to major inorganic constituents and rare earth elements. A slightly higher relative SD was found for elements that may stem from biological or anthropogenic input. The element concentrations determined in this work are discussed in comparison to concentrations in other similar reference materials. Concentrations for 31 elements will be included for information on the certificate.

Establishing Baseline Levels of Elements in Marine Mammals Through Analysis of Banked Liver Tissues

ACS symposium series (1997)

Paul R. Becker Elizabeth A. Mackey Rabia Demiralp Barbara J. Koster Stephen A. Wise

Tissues from marine mammals of the United States are routinely banked in the National Biomonitoring Specimen Bank through collaboration between the National Institute of Standards and Technology, the National Marine Fisheries Service, the National Biological Service, and numerous other agencies and organizations. A major part of this specimen banking involves collections from marine mammals taken in Alaska Native subsistence hunts. Subsamples of liver tissues banked from these collections are routinely analyzed for 39 elements, using instrumental neutron activation analysis, supplemented with other analytical techniques. Excluding the potentially toxic trace elements (e.g., Hg and Cd) and a few essential elements (e.g., Cu, Se, and Zn), the published database on element concentrations in marine mammals has been limited. The program described here offers an opportunity for establishing baseline levels for a wide range of major, minor, and trace elements in marine mammals of the western Arctic and North Pacific oceans.
