Isotopic and elemental characterization of colloidal organic matter from the Chesapeake Bay and Galveston Bay
(, 1997 Dec)
In order to investigate sources and turnover rates of dissolved organic matter from Chesapeake Bay and Galveston Bay, colloidal organic matter (COM) was isolated using cross-flow ultrafiltration and subsequently characterized ...
Partitioning of Cu, Pb, Ag, Zn, Fe, Al, and Mn Between Filter-Retained Particles, Colloids, and Solution in 6 Texas Estuaries
(, 1994 Mar)
There are few methodical studies of processes controlling trace metal behavior in estuaries, where river water gradually mixes with seawater leading to systematic changes in ionic strength, pH, DOC, nutrient concentrations, ...
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, ...
Historical contamination of PAHs, PCBs, DDTs, and heavy metals in Mississippi River Delta, Galveston Bay and Tampa Bay sediment cores
(, 2001 Jul)
Profiles of trace contaminant concentrations in sediment columns can be a natural archive from which pollutant inputs into coastal areas can be reconstructed. Reconstruction of historical inputs of anthropogenic chemicals ...
Colloidal pumping: Evidence for the coagulation process using natural colloids tagged with Hg-203
(, 1996 Nov)
Colloids isolated from waters of the Trinity River (Texas) were tagged with high specific activity mercury (Hg-203) and re-equilibrated with ultrafiltered water and particles. The transfer of radioisotopic Hg from the ...
