1. Spatial and temporal trends of persistent organic pollutants and mercury in beluga whales (Delphinapterus leucas) from Alaska
Jennifer J. Hoguet, Jessica L Reiner, Jennifer M Keller, John R Kucklick, Colleen E Bryan, Amanda J Moors, Rebecca S Pugh, Paul R Becker
Remote locations, such as the Arctic, are often sinks for persistent contaminants which can ultimately bioaccumulate in local wildlife. Assessing temporal contaminant trends in the Arctic is important in understanding whether restrictions on legacy ...
2. Does 47 Days of Decay Change Persistent Organic Pollutants in Loggerhead Sea Turtle Eggs?
Jennifer M Keller
Reptile and bird eggs are priority samples for specimen banking programs that assess spatial and temporal trends of environmental contaminants. From endangered species, such as sea turtles, non-lethal sampling is required, like collecting unhatched ...
3. Organonhalogen Contaminants and Mercury in Beluga Whale Tissues Banked by the Alaska Marine Mammal Tissue Archival Project
NIST Interagency/Internal Report (NISTIR)
Jessica L Reiner, Jennifer J. Hoguet, Jennifer M Keller, John R Kucklick, Colleen E Bryan, William C Davis, Amanda J Moors, Rebecca S Pugh, Paul R Becker
4. Perfluoroalkyl Contaminants in Plasma of Five Sea Turtle Species: Comparisons in Concentration and Potential Health Risks
Jennifer M Keller, Lily Ngai, Joanne Braun-McNeill, Larry Wood, Kelly Stewart, Steven O'Connell, John R Kucklick
We compared the plasma concentration of 13 perfluorinated contaminants (PFCs) in five sea turtle species. Perfluorooctane sulfonate (PFOS) was predominant in most species, except hawksbills had higher concentrations of perfluorononanoate. Excluding s ...
5. Determination of Perfluorinated Alkyl Acid Concentrations in Biological Standard Reference Materials
Jessica L Reiner, Jennifer M Keller, Michele M Schantz, Steven O'Connell, Craig M Butt, Scott Mabury, Jeff Small, Amila De Silva, Derek Muir, Amy D Delinsky, Mark J Strynar, Andrew B. Lindstrom, William K Reagen, Michelle Malinsky, Sandra Schafer, Christiaan Kwadijk
Standard Reference Materials (SRMs) are homogeneous, well-characterized materials that are used to validate measurements and improve the quality of analytical data. The National Institute of Standards and Technology (NIST) has a wide range of SRMs th ...
6. The immunotoxicity of perfluorinated compounds: Recent developments
Jennifer M Keller, Jamie DeWitt, M.M. Peden-Adams, Dori Germolec
Perfluorinated compounds (PFCs) are environmentally widespread, persistent, and bioaccumulative chemicals with multiple toxicities reported in experimental models and wildlife, including immunomodulation. The two most commonly detected compounds, whi ...
7. Organohalogen contaminant concentrations in diamondback terrapins from Barnegat Bay, New Jersey
Jennifer M Keller, Emily Basile, Harold Avery
The northern diamondback terrapin’s (Malaclemys terrapin) wide geographic distribution, existence in a variety of habitats within the saltmarsh ecosystem, predatory foraging behavior and site fidelity make it an excellent indicator species for contam ...
8. Determination of perfluorinated compounds in human plasma and serum Standard Reference Materials using independent analytical methods
Jessica L Reiner, Karen W Phinney, Jennifer M Keller
Perfluorinated compounds (PFCs) were measured in three National Institute of Standards and Technology Standard Reference Materials (SRMs 1950 Metabolites in Human Plasma, SRM 1957 Organic Contaminants in Non-fortified Human Serum, and SRM 1958 Organi ...
9. Persistent Organic Pollutant Concentrations in Fat, Blubber, Blood and Eggs of Leatherback Turtles with Confirmation of Maternal Transfer
Jennifer M Keller, John R Kucklick, Kelly R Stewart, Ryan Templeton, Chris Johnson
Among contaminant studies in reptiles, turtles, and in particular sea turtles, are poorly represented. To assess threats to this endangered species, it is critical to establish baseline values for contaminant concentrations that may have detrimental ...
10. Geographical variation of Persistent Organic Pollutants in eggs of threatened loggerhead sea turtles (Caretta caretta) from Southeastern USA
Jennifer M Keller, Juan Alava, Jeanette Wyneken, Larry Crowder, Geoffrey Scott, John R Kucklick
Persistent organic pollutants (POPs) are a recognized man-made threat to sea turtle populations, but the uncertainty surrounding exposure and sensitivity of sea turtles to contaminants is great and makes decision making difficult for conservation man ...
