Distribution and partitioning of trace metals (Cd, Cu, Ni, Pb, Zn) in Galveston Bay waters
(, 2002 Apr)
The distribution of several trace metals has been studied in the surface waters of Galveston Bay, Texas, in order to assess the impact of complexation with organic and reduced sulfur species on the partitioning of trace ...
Colloids in oceanic environments: Composition and importance for trace element cycles
Proceedings of meetings.
Trace metal analysis of natural waters by ICP-MS with on-line preconcentration and ultrasonic nebulization
(, 1999 Feb)
Concentrations of Mn, Ni, Cu, Zn and Pb in natural waters were measured by inductively coupled plasma mass spectrometry (ICP-RIS) with on-line preconcentration using Toyopearl TSK-immobilized 8-hydroxyquinoline resin columns ...
Mercury phase speciation in the surface waters of three Texas estuaries: Importance of colloidal forms
(, 1996 Jan)
Surface-water samples were collected from Galveston Bay, Corpus Christi Bay, Sabine Lake, and Laguna Madre and analyzed for Hg in the <0.45-mu m, 0.45-mu m-1-kDa, and <1-kDa fractions. Colloidal material was isolated with ...
Interactions between radioactively labeled colloids and natural particles: Evidence for colloidal pumping
(, 1997 Jul)
It has been hypothesized that colloidal forms of trace metals can be reactive intermediaries in the scavenging processes leading to the removal of their particulate forms. A series of radiotracer experiments using natural ...
Sediment-water exchange of Mn, Fe, Ni and Zn in Galveston Bay, Texas
(, 2001 Mar)
In-situ benthic flux studies were conducted at three stations in Upper Galveston Bay twice during March 1996 to directly measure release rates of dissolved Mn, Fe, Mi and Zn from the sediments. Results showed reproducible ...

Colloidal and particulate silver in river and estuarine waters of Texas
(, 1997 Mar)
Concentration and phase speciation of Ag in selected Texas rivers and in the Trinity River estuary were measured in order to establish the major factors that control its fate in the aquatic environment from source to sink. ...
Biogeochemical behavior of organic carbon in the Trinity River downstream of a large reservoir lake in Texas, USA
(, 2004 Aug)
Dissolved and particulate organic carbon concentrations were measured and annual loads estimated for the Trinity River, the main freshwater input source to Galveston Bay, which lies on the upper Gulf coast of Texas, USA, ...
Cycling of high molecular weight dissolved organic matter in Galveston Bay and the Chesapeake Bay
