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