1. FACTORS INFLUENCING EXPOSURE TO ORGANOHALOGEN CONTAMINANTS IN PREDATORY BIRDS FROM COASTAL SOUTH CAROLINA, USA
Topic: Organic Analytical Chemistry
Published: 3/15/2013
Authors: Jessica L Reiner, Jennifer Yordy, Sam Rossman, Peggy H. Ostrom, Stacy Hughes, Keely Bargnesi, James D. Elliot
Abstract: Predatory bird species occupy high trophic levels and consequently are susceptible to bioaccumulating high levels of environmental contaminants. To evaluate potential risks from exposure to past- and current- use contaminants, levels of legacy contam ...

2. Determination of fortified and endogenous folates in food-based Standard Reference Materials by liquid chromatography-tandem mass spectrometry
Topic: Organic Analytical Chemistry
Published: 1/26/2013
Authors: Johanna Camara, Mark S Lowenthal, Karen W Phinney
Abstract: The National Institute of Standards and Technology (NIST) is developing a wide variety of Standard Reference Materials (SRMs) to support measurements of vitamins and other nutrients in foods. Previously, NIST has provided SRMs with values assigned f ...

3. Spatial and temporal trends of persistent organic pollutants and mercury in beluga whales (Delphinapterus leucas) from Alaska
Topic: Organic Analytical Chemistry
Published: 1/24/2013
Authors: Jennifer J. Hoguet, Jessica L Reiner, Jennifer M Keller, John R Kucklick, Colleen E Bryan, Amanda J Moors, Rebecca S Pugh, Paul R Becker
Abstract: 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 ...

4. Does 47 Days of Decay Change Persistent Organic Pollutants in Loggerhead Sea Turtle Eggs?
Topic: Organic Analytical Chemistry
Published: 1/18/2013
Author: Jennifer M Keller
Abstract: 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 ...

8. Perfluoroalkyl Contaminants in Plasma of Five Sea Turtle Species: Comparisons in Concentration and Potential Health Risks
Topic: Organic Analytical Chemistry
Published: 5/23/2012
Authors: Jennifer M Keller, Lily Ngai, Joanne Braun-McNeill, Larry Wood, Kelly Stewart, Steven O'Connell, John R Kucklick
Abstract: 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 ...
