Abstract

The National Institute of Standards and Technology (NIST), in support of the National Oceanic & Atmospheric Administrations Marine Mammal Health and Stranding Response Program (NOAA/MMHSRP), conducts annual interlaboratory comparison exercises for the determination of chlorinated pesticides, polychlorinated biphenyl congeners (PCBs), & trace elements in marine mammal tissues. These exercises provide one mechanism for laboratories to evaluate their measurement quality & comparability for these constituents in marine mammal tissues. In the 2007 exercise, 21 data sets were submitted by 14 laboratories on requested organohalogen compounds in marine blubber & serum or fatty acids in marine mammal blubber. The materials distributed for the 2007 exercise included SRM 1945 Organics in Whale Blubber, SRM 1958 Human Serum (Fortified), a homgenized blubber control material Marine Mammal Quality Assurance Exercise Homogenate VIII (Homogenate VIII) from a female pilot whale and Marine Mammal Control Material 1-Serum (MMCM1-serum) derived from an adult male California sea lion (Zalophus californianus). This report includes the results reported by the paricipating laboratories, combined consensus data results, & summary statistics for each analyte in the samples. The numerical indices used to assess laboratory performance are also discussed.
