Consideration and Influence of Complexed forms of Mercury Species on the reactivity Patterns Determined by Speciated Isotope Dilution Model Approaches: A Case for Natural Biological Reference Materials

June 1, 2008
Author(s)
David Point, J. I. Garcia Alonso, William C. Davis, Steven J. Christopher, Aurore Guichard, O.F. X. Donard, Paul R. Becker, Gregory C. Turk, Stephen A. Wise
The origins and the processes driving the inadvertent transformations of inorganic mercury (iHg) and methylmercury (MeHg) in cryogenically stored and homogenized fresh-frozen versus freeze-dried biological Standard Reference Materials (SRM) were

Monitoring Contaminants in Seabirds: The Importance of Specimen Banking

November 13, 2007
Author(s)
Stacy S. Vander-Pol, Paul R. Becker
Historically, contaminants in seabird tissues were monitored by considering physically visible effects; however, subtle, sub-lethal effects are also important. Several long-term monitoring and specimen banking programs are in place for seabirds, and the

John R. Kucklick, M M. Krahn, Paul R. Becker, Barbara J. Porter, Michele M. Schantz, Geoffrey S. York, T M. O'Hara, Stephen A. Wise
Since 1987, the Alaska Marine Mammal Tissue Archival Project (AMMTAP) has collected tissues from 18 marine mammals species. Specimens are archived in the National Institute of Standards and Technology s National Biomonitoring Specimen Bank (NIST-NBSB)

Ionizing Radiation-Induced Destruction of Benzene and Dienes in Aqueous Media

March 28, 2006
Author(s)
M I. Al-Sheikhly, Dianne L. Poster, Jung-Chul An, Pedatsur Neta, Joseph Silverman, Robert E. Huie
Pulse radiolysis with spectrophotometric and conductometric detection was utilized to study the formation and reactions of radicals from benzene and dienes in aqueous solutions. The benzene OH adduct, C6H6OH, reacts with O2 (k = 3 x 108 L mol-1 s-1) in a
