NOAA National Status and Trends Program Sixth Round Intercomparison ExerciseResults for Trace Metals in Marine Sediments and Biological Tissues

摘要

The report, prepared by the National Research Council of Canada, summarizesresults of the National Oceanic and Atmospheric Administration (NOAA) National Status and Trends Program sixth round intercomparison exercise for trace metals in marine sediments and biological tissues. This excercise is one in a series of annual intercomparisons sponsored by NOAA and EPA doing agency-funded chemical analyses. In addition, the exercises have been opened to other laboratories resulting in forty-two potential participants for the 1992 exercise. The exercise materials were a spray dried sample of filletted flounder collected off the coast of the east coast of Nova Scotia and a freeze dried marine sediment collected in the Chesapeake Bay. Reference materials NRC CRM DORM-1 and BCSS-1 were also analyzed as part of the exercise.
