Liquid chromatography tandem mass spectrometry for the quantitation of steroid hormone profiles in blubber from stranded humpback whales (Megaptera novaeangliae)

July 30, 2019
Author(s)
Greta Dalle Luche, Susan Bengston Nash, John Kucklick, Fletcher M. Mingramm, Ashley Russell
Marine mammal blubber is known to have quantifiable concentrations of steroid hormones and is increasingly chosen as a matrix for the detection of these reproductive and stress biomarkers. Steroid hormones act through complex cascades, often in concert

Remote blubber sampling paired with liquid chromatography tandem mass spectrometry for steroidal endocrinology in free-ranging bottlenose dolphins (Tursiops truncatus)

June 11, 2019
Author(s)
Ashley S. Boggs-Russell, Jared M. Ragland, Eric Zolman, Tracey B. Schock, Jeanine S. Morey, Thomas M. Galligan, Greta Dalle Luche, Brian C. Balmer, Randall S. Wells, John R. Kucklick, Lori Schwacke
Liquid chromatography tandem mass spectrometry allows for the measurement of steroid hormone suites in the blubber of marine mammals. By combining this technology with minimally invasive techniques such as remote biopsy, endocrine profiles can be assessed

A Review of Organotin Contamination in Arctic and Subarctic Regions

May 17, 2019
Author(s)
John Kucklick, MIchael Ellisor
Organotin (OT) compounds are of continued arctic concern as they still widely used despite the most well-studied OT, tributyl tin (TBT), being restricted for use on marine vessels to prevent fouling by marine organisms. The highest OT concentrations found

Racial Disparity in Maternal Phthalates Exposure; Association with Racial Disparity in Fetal Growth and Birth Outcomes

April 10, 2019
Author(s)
Michael S. Bloom, Abby G. Wenzel, John W. Brock, Rebecca J. Wineland, Lori Cruze, Elizabeth R. Unal, Assem Jiyessova, Roger B. Newman, John Kucklick
Background: Experimental and observational data implicate phthalates as developmental toxicants. However, few data are available to assess the maternal risks of gestational exposure by race and infant sex. Objectives: To characterize associations between

A Review of Halogenated Natural Products in Arctic, Subarctic and Nordic Ecosystems

February 19, 2019
Author(s)
Terry Bidleman, Agneta Andersson, Liisa Jantunen, John Kucklick, Henrik Kylin, Robert Letcher, Mats Tysklind, Fiona Wong
Halogenated natural products (HNPs) are organic compounds containing bromine, chlorine, iodine, and sometimes fluorine. HNPs comprises many classes of compounds, ranging in complexity from halocarbons (mostly halomethanes and haloethanes) to higher

A status of temporal trends of persistent organic pollutants in Arctic biota

February 1, 2019
Author(s)
Frank Riget, Anders Bignert, Birgit Braune, Maria Dam, Rune Dietz, Marlene Evans, Norman Green, Helga Gunnlaugsdottir, Katrin S. Hoydal, John Kucklick, Robert Letcher, Derek Muir, Stacy Schuur, Christian Sonne, Stern Gary, Gregg Tomy, Katrin Vorkamp, Simon Wilson
More than 1000 time-series of persistent organic pollutants (POPs) in Arctic biota from marine and freshwater ecosystems some extending back to the beginning of 1980s were analyzed using a robust statistical method. The Arctic area encompassed extended

Urinary Phthalate Metabolites in Common Bottlenose Dolphins (Tursiops truncatus) from Sarasota Bay, FL, USA

September 5, 2018
Author(s)
Leslie Hart, Barbara Beckingham, Randall Wells, Moria Alten-Flagg, Kerry Wischusen, Amanda Moors, John Kucklick, Pisarski Emily, Ed Wirth
Phthalates are chemical additives to common consumer goods including cleaning products, cosmetics, personal care products, and plastic. Because they are not chemically bound to these products and are widely used, the potential for environmental

Halogenated natural products

December 29, 2017
Author(s)
Terry Bidleman, John Kucklick, Henrik Kylin, Robert Letcher, Liisa Jantunen, Fiona Wong
This chapter summarizes the occurrence and fate on HNPs in the arctic physical environment and accumulation processes and presence in arctic biota. Except for halocarbons, there have been few investigations of HNPs in polar environments. Discussions of HNP

Rapid and reliable steroid hormone profiling in Tursiops truncatus blubber using liquid chromatography tandem mass spectrometry (LC-MS/MS)

June 1, 2017
Author(s)
Ashley S. Boggs-Russell, Tracey B. Schock, Thomas M. Galligan, Wayne E. McFee, Jeanine S. Morey, Lori Schwacke, John R. Kucklick
Monitoring of marine mammal steroid hormone status using matrices alternative to blood is desirable due to the ability to remotely collect samples which minimizes stress. However, measurement techniques in alternative matrices such as blubber described to

Persistent organic pollutants in blood samples of Southern Giant Petrels (Macronectes giganteus) from the South Shetland Islands, Antarctica

May 26, 2016
Author(s)
Fernanda I. Colabuono, Stacy Schuur, Kevin Huncik, Satie Taniguchi, Petry V. Maria, John Kucklick, Rosalinda C. Montone
Seabirds play an important role as top consumers in the food web and can be used as biomonitors of exposure to pollutants. Contamination studies on seabirds involving non-destructive sampling methods are of considerable importance, allowing better

Development of Two Fine Particulate Matter Standard Reference Materials ( 4 mm and 10 mm) for the Determination of Organic and Inorganic Constituents

April 13, 2016
Author(s)
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
