1. Persistent organic pollutant concentrations in blubber of 16 species of cetaceans stranded in the Pacific Islands from 1997 through 2011
Melannie J Bachman, Jennifer M Keller, Kristi West, Brenda Jensen
Persistent organic pollutants (POPs) are toxic man-made chemicals that bioaccumulate and biomagnify in food webs, making them a ubiquitous threat to the marine environment. Although many studies have determined concentrations of POPs in top predators ...
2. BIOLOGICAL AND ENVIRONMENTAL MONITORING AND ARCHIVAL OF SEA TURTLE TISSUES (BEMAST): Rationale,
Protocols, and Initial Collections of Banked Sea Turtle Tissues
NIST Interagency/Internal Report (NISTIR)
Jennifer M Keller, Rebecca S. (Rebecca) Pugh, Paul R Becker
The National Institute of Standards and Technology (NIST) expanded its analytical measurement and
specimen banking capabilities into the U.S. Pacific Islands region in 2010. As part of this Program,
NIST established the Biological and Environment ...
3. MILK AND SERUM SRMs for MONITORING ORGANIC CONTAMINANTS IN HUMAN SAMPLES
Michele M Schantz, Katherine E Sharpless, Stephen A Wise, Rebecca Heltsley, Jennifer Keller, John Kucklick, Stacy VanderPol, Stefan D Leigh, Donald G. Patterson, Jr., Andreas Sjodon, Wayman E. Turner
Four new Standard Reference Materials (SRMs) have been developed to assist in the quality assurance required for human biomonitoring studies. These materials are SRM 1953 Organic Contaminants in Non-Fortified Human Milk, SRM 1954 Organic Contamiants ...
4. 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. (Rebecca) 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 ...
5. 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 ...
6. 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. (Rebecca) Pugh, Paul R Becker
7. 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 ...
8. 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 ...
9. 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 ...
10. 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 ...
