Alvarado Quiroz, Nicolas Gabriel (Texas A&M University, 2005-08-29)The functional group composition of acid polysaccharides was determined after isolation using cross-flow ultrafiltration, radiolabeling with 234Th(IV) and other isotopes, and separation using isoelectric focusing (IEF) and ...

Landin, Charles Melchor (2009-05-15)The formation of dissolved gaseous mercury (DGM) can be an important pathway for mercury removal from an aquatic environment. DGM evasional fluxes from an aquatic system can account for up to 95% of atmospheric Hg and its ...

Xu, Chen (2012-10-19)Radionuclides, 129I and 239,240Pu, are major products or by-products of nuclear fission and among the top risk drivers for waste disposal at the Savannah River Sites (SRS) and Rocky Flats Environmental Technology Sites ...

Zhang, Saijin (2011-10-21)A series of laboratory and field investigations were carried out to elucidate the importance of natural organic matter in aquatic systems, i.e., trace element scavenging (e.g., 234Th) by exopolymeric substances (EPS), ...

Role of natural organic matter in governing the bioavailability of toxic metals to american oysters Haye, Jennifer Marcelle (Texas A&M University, 2006-08-16)Colloidal macromolecular organic matter (COM), which makes up a large portion of the bulk dissolved organic matter (DOM) in marine environments, has the capability to modify the bioavailability of potentially toxic metals ...

Li, Hsiu-Ping (2012-10-19)129I is of major concern because of its biophilic nature, excessive inventory, long half-life (~16 million yrs), and high mobility in the natural environment that depends on its chemical speciation. Iodide (I-) has the ...

Schwehr, Kathleen A.; Santschi, Peter H. (Texas Water Resources Institute, 2002)The objective of this study is to develop an analytical method that uses readily available instrumentation and minimal sample preparation for the determination of stable lodine species at nanomolar concentration levels in ...
-
Schwehr, Kathleen Ann (Texas A&M University, 2005-02-17)Iodine is a biophilic element with one natural long-lived isotope, 129I (t1/2= 15.6 million years), and one stable isotope, 127I. The inventory of 129I in surface environments has been overwhelmed by anthropogenic releases ...

Yard, AlexandraThis project investigated the toxicity of weathered oil on an oil resistant diatom species, Phaeodactylum tricornutum. Most oil toxicology studies focus on the use of fresh oil, while phytoplankton that live in the euphotic ...
