Polymer Identification of Plastic Debris Ingested by Pelagic-phase Sea Turtles in the Central Pacific

September 12, 2018
Author(s)
Melissa R. Jung, George H. Balazs, Thierry M. Work, T. T. Jones, Sara Orski, Viviana Rodriguez, Kathryn Beers, S. A. Abriola, K. D. Hyrenbach, Brenda A. Jensen, Jennifer Lynch
Pelagic Pacific sea turtles eat large quantities of plastic. We identified the polymers ingested by 37 olive ridley, 9 green and 4 loggerhead sea turtles caught as bycatch in Pacific longline fisheries using Fourier transform infrared spectroscopy

Chronic Debilitation in Stranded Loggerhead Sea Turtles (Caretta caretta) in the Southeastern United States: Morphometrics and Clinicopathological Findings

July 10, 2018

Nicole Stacy, Jennifer Lynch, Michael D. Arendt, Larisa Avens, Joanne Braun McNeill, Carolyn Cray, Russell D. Day, Craig A. Harms, A. M. Lee, Margie Peden-Adams, Kelly Thorvalson, Al L. Segars, Terry Norton
Chronically debilitated loggerhead sea turtles (Caretta caretta) (DT) are characterized by emaciation, lethargy, and heavy barnacle coverage. We examined and sampled 43 DTs from North Carolina to Florida for a broad suite of health variables using

Validation of ATR FT-IR to identify polymers of plastic marine debris, including those ingested by marine organisms

January 3, 2018

Melissa R. Jung, F. D. Horgen, Sara Orski, Viviana Rodriguez Cardenas, Kathryn Beers, George H. Balazs, T. T. Jones, Thierry M. Work, Kayla C. Brignac, Sarah-Jeanne Royer, K. D. Hyrenbach, Brenda A. Jensen, Jennifer Lynch
Polymer identification of plastic marine debris can help identify its sources, degradation, and fate. We optimized and validated a fast, simple, and accessible technique, attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT-IR), to

Development of Two Fine Particulate Matter Standard Reference Materials (

April 13, 2016

Michele M. Schantz, Danielle Cleveland, N. Alan Heckert, John Kucklick, Stefan D. Leigh, Stephen E. Long, Jennifer Lynch, Karen E. Murphy, Rabia Oflaz, Adam L. Pintar, Barbara J. Porter, Savelas A. Rabb, Stacy Schuur, Stephen Wise, Rolf L. Zeisler
Two new Standard Reference Materials (SRMs), SRM 2786 Fine Particulate Matter ( 4 µm) and SRM 2787 Fine Particulate Matter ( 10 µm) have been developed in support of the US Environmental Protection Agency's National Ambient Air Quality Standards for

Organohalogen contaminants and vitamins in Northern Fur Seals (Callorhinus ursinus) collected during subsistence hunts in Alaska

January 1, 2016

Jessica L. Reiner, Paul R. Becker, Jennifer M. Lynch, Amanda J. Moors, Jennifer M. Ness, Rebecca S. Pugh, Catherine A. Rimmer, John R. Kucklick, Matthew O. Gribble, Danielle Peterson, Jody Rhoderick, Jennifer Trevillian
During native subsistence hunts from 1987 to 2007, blubber and liver samples from 50 subadult male northern fur seals (Callorhinus ursinus) were collected on St. Paul Island, Alaska. Samples were analyzed for legacy persistent organic pollutants (POPs)

Using cytochrome P4501A1 expression in liver and blubber to understand effects of persistent organic pollutant exposure in stranded Pacific Island cetaceans

April 18, 2015
Author(s)
Melannie J. Bachman, Jennifer M. Lynch, Kerry Foltz, Kristi West, Brenda Jensen
Elevated levels of persistent organic pollutants (POPs) have been reported in tropical Pacific Island cetaceans and their environment. In addition, recent health concerns in cetacean populations have warranted investigation into potential physiological

Perfluorinated Alkyl Acids in Abiotic Standard Reference Materials

April 1, 2015
Author(s)
Jessica L. Reiner, Jennifer M. Lynch, Andrea Blaine, Christopher Higgins, Carin Huset, Thomas Jenkins, Christiaan Kwadijk, Cleston Lange, Derek Muir, William K. Reagen, Courtney Rich, Jeff Small, Mark J. Strynar, John Washington, Hoon Yoo
The National Institute of Standards and Technology (NIST) has a wide range of Standard Reference Materials (SRMs) which have values assigned for legacy organic pollutants and toxic elements. Existing SRMs serve as homogenous materials that can be used for

Persistent Organic Pollutants and Vitamins in Northern Fur Seals (Callorhinus ursinus) Collected from St. Paul Island, Alaska as Part of the Alaska Marine Mammal Tissue Archival Project

August 1, 2013
Author(s)
John Kucklick, Jessica Reiner, Michele M. Schantz, Jennifer Lynch, Jennifer Hoguet, Kate Rimmer, Rebecca Pugh, Jody Rhoderick, Jennifer Ness, Paul R. Becker, Danielle Peterson
Liver and blubber samples from 50 juvenile male northern fur seals (Callorhinus ursinus) were collected on St. Paul Island from four different seal rookeries between 1987 and 2007. Samples were analyzed for vitamins and for both legacy and current-use

Spatial and temporal trends of persistent organic pollutants and mercury in beluga whales (Delphinapterus leucas) from Alaska

January 24, 2013
Author(s)
Jennifer Hoguet, Jessica Reiner, Jennifer Lynch, John Kucklick, Colleen E. Bryan Sallee, Amanda Moors, 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

Perfluoroalkyl Contaminants in Plasma of Five Sea Turtle Species: Comparisons in Concentration and Potential Health Risks

May 23, 2012
Author(s)
Jennifer M. Lynch, 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
