Water tracing with soluble metal chelates and neutron activation analysis : a laboratory and field study

Creator:: Hanson, Peter James
Abstract:: Research on the application of soluble, metal chelates for water tracing using thermal neutron activation analysis for tracer determination has led to the development of several tracers with promising solution stabilities (conservative behavior) and determination sensitivities. The solution stabilities of the ethylenediamine tetraacetic acid (EDTA) and the diethylenetriamine pentaacetic acid...

Radioecology of ⁶⁵Zn in an arm of the Columbia River Estuary

Creator:: Renfro, William Charles
Abstract:: Levels of ⁶⁵Zn in water, sediments, plants, and animals in Alder Slough, a small ecosystem in the Columbia River Estuary, were determined periodically during a one year period. Concentrations of total Zn in organisms were also measured to permit computation of specific activities (μCi⁶⁵Zn/g total Zn). Temporal fluctuations in the...

Vertical distribution of radioactivity in the Columbia River estuary

Creator:: Hanson, Peter James
Abstract:: In situ salinity, turbidity and temperature were measured at discrete depths and water samples for radioanalysis were simultaneously collected in the Columbia River Estuary using a specially designed instrument package. Particulate radioactivity was concentrated by filtration and the dissolved radioactivity by evaporation or ferric oxide bulk precipitation. Radioanalysis was by...

Extraction of zinc from sea water

Creator:: Buffo, Lynn Karen
Abstract:: A liquid-extraction procedure for the concentration of zinc in sea water was developed. The metal ion in sea water was chelated with sodium diethyldithiocarbamate and extracted into an organic solvent, methylisobutylketone, at the normal pH of sea water. A back-extraction into HCl followed, providing a concentration of 30X for the...

Plankton and nutrient ecology of the Columbia River estuary

Creator:: Haertel, Lois Steben
Abstract:: Monthly samples of nutrients, phytoplankton and zooplankton were taken in the Columbia River estuary over a period of 16 months in order to determine distribution with season and salinity, and interrelationships between plankton and nutrients. Nitrate and phosphate levels in the river water entering the estuary are high in the...

Chromium-51 in the Columbia River and adjacent Pacific Ocean

Creator:: Cutshall, N. H.
Abstract:: Radioactive chromium-51, a waste byproduct from operation of nuclear reactors at Hanford, Washington, has been followed down the Columbia River and into the Pacific Ocean. Chemical factors influencing the partitioning of ⁵¹Cr between solution and sediment have been considered. Chromium-5l, in a hexavalent oxyanion when introduced into the Columbia River,...
