Development of a murre (Uria spp.) egg control material

摘要: The Seabird Tissue Archival and Monitoring Project (STAMP) is a collaborative Alaska-wide effort by the US Fish Wildlife Service’s Alaska Maritime National Refuge (USFWS/AMNWR), Geological Survey’s Biological Resources Division (USGS/BRD), Bureau of Indian Affairs Region Subsistence Branch (BIA/ARSB), Institute Standards Technology (NIST) to monitor long-term (decadal) trends in environmental contaminants using seabird eggs. To support this effort, matrix- (seabird egg) concentration-specific control material was needed ensure quality during analytical work. Although herring gull egg assurance (HGQA) available from Environment Canada (EC), contaminant concentrations tended be higher than those observed Alaskan murre (Uria spp.) Therefore, prepare more appropriate material, total 12 common (U. aalge) thick-billed lomvia) eggs four Bering Sea Gulf nesting locations were cryohomogenized create 190 aliquots each containing approximately 6 g. This new analyzed different methods at NIST EC facilities for determination value assignment 63 polychlorinated biphenyl (PCB) congeners, 20 organochlorine pesticides, 11 polybrominated diphenyl ether (PBDE) congeners. PCB concentration 58 ng g−1 wet mass. Results obtained analytes not listed on certificates analysis previously used materials, HGQA NIST’s Standard Reference Material (SRM) 1946 Lake Superior Tissue, are also presented.
