Geographical variation of Persistent Organic Pollutants in eggs of threatened loggerhead sea turtles (Caretta caretta) from Southeastern USA

April 4, 2011
Author(s)
Jennifer M. Lynch, 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 managers

Specimen Banking for Marine Animal Health Assessment

November 8, 2010
Author(s)
John R. Kucklick, Rebecca S. Pugh, Paul R. Becker, Jennifer M. Lynch, Russell D. Day, Jennifer Yordy, Amanda J. Moors, Steven J. Christopher, Colleen E. Bryan Sallee, Lori Schwacke, Randall S. Wells, Brian C. Balmer, Aleta Hohn, Teri Rowles
Marine animals are faced with health threats including disease and accumulation of toxic pollutants. There are several efforts in the USA seeking to relate health metrics to the exposure of marine animals to pollution, biotoxins, and disease. The National

Comparison of Mercury Burdens in Chronically Debilitated and Healthy Loggerhead Sea Turtles (Caretta caretta)

January 15, 2010
Author(s)
Russell D. Day, Jennifer M. Lynch, Craig A. Harms, Al L. Segars, Wendy M. Cluse, Matthew H. Godfrey, A. M. Lee, Margie Peden-Adams, Kelly Thorvalson, Mark Dodd, Terry Norton
An increase in the incidence of debilitated loggerhead sea turtle strandings in the southeastern U.S. has been observed in recent years. These turtles are characterized by emaciation and heavy burdens of external and internal parasites and bacterial

Organohalogen contaminants in blood of Kemp's ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas) from the Gulf of Mexico

December 9, 2009
Author(s)
Robert R. Swarthout, Jennifer Lynch, Margie Peden-Adams, Andre Landry, Patricia Fair, John Kucklick
The threat that exposure to organohalogen (OH) contaminants poses to endangered populations of Kemp's ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas) is not well understood, partly because few OH data are available. Blood samples from

Determination of Perfluorinated Alkyl Acid concentrations in Human Serum and Milk Standard Reference Materials

October 28, 2009
Author(s)
Jennifer M. Lynch, Antonia M. Calafat, Kayoko Kato, Mark E. Ellefson, William K. Reagen, Mark Strynar, Steven G. O'Connell, Craig M. Butt, Scott Mabury, Jeff Small, D.C.G. Muir, Stefan D. Leigh, Michele M. Schantz
Standard Reference Materials (SRMs) are homogeneous, well-characterized materials that are used to validate measurement methods and are critical in improving data quality. Disagreements in perfluorinated alkyl acid (PFAA) concentrations measured in

Comparison of five extraction methods for measuring PCBs, PBDEs, organochlorine pesticides, and lipid content in serum

April 7, 2009
Author(s)
Jennifer M. Lynch, Aurore Guichard, Jennifer Yordy, Michele M. Schantz, John R. Kucklick, Robert R. Swarthout, Brianna K. Carlson
An increasing number of studies use blood obtained non-invasively to monitor organohalogen contaminants. However, blood can be a difficult tissue to analyze for organohalogen pollutants due to interferences from co-extracted proteins. We compared five

Fish-Related Standard Reference Materials

February 1, 2009
Author(s)
Michele M. Schantz, Steven J. Christopher, William C. Davis, Russell D. Day, Jennifer M. Lynch, John R. Kucklick, Stephen E. Long, Elizabeth A. Mackey, Barbara J. Porter, Dianne L. Poster, Katherine E. Sharpless, Gregory C. Turk, Stephen A. Wise
The National Institute of Standards and Technology (NIST) has developed four Standard Reference Materials (SRMs) related to the monitoring of contaminants in fish and marine mammals: SRM 1588b Organics in Cod Liver Oil, SRM 1945 Organics in Whale Blubber

Spotlighting NIST Standard Reference Materials - New Standard Reference Material (SRM) 2585 Organic Contaminants in House Dust to Support Exposure Assessment Measurements

June 1, 2007
Author(s)
Michele M. Schantz, Jennifer M. Lynch, John R. Kucklick, Dianne L. Poster, H M. Stapleton, S S. Vander Pol, Stephen A. Wise
House dust originates from both internal and external sources and has been identified as one of the primary sources of lead exposure for children (http://www.epa.gov/lead). House dust is also a repository for pesticides, flame retardants, and other

NIST Inter-Comparison Exercise Program for Polybrominated Diphenyl Ethers (PBDEs) in Marine Sediment: Description and Results of the 2004 Intercomparison Exercise

June 1, 2006
Author(s)
H M. Stapleton, Jennifer M. Lynch, Michele M. Schantz, John R. Kucklick, Stephen A. Wise
In support of environmental monitoring measurement programs, the National Institute of Standards and Technology (NIST) conducts inter-laboratory comparison exercises to provide one mechanism for participating laboratories/monitoring programs to evaluate

Determination of Polybrominated Diphenyl Ethers in Indoor Dust Standard Reference Materials

February 1, 2006
Author(s)
H M. Stapleton, T. Harner, M. Shoeib, Jennifer M. Lynch, Michele M. Schantz, Stefan D. Leigh, Stephen A. Wise
Polybrominated diphenyl ethers (PBDEs) have been measured for the first time in three different indoor dust Standard Reference Materials (SRMs) prepared by the National Institute of Standards and Technology (NIST). Two of these SRMs (2583 and 2584) have
