[PDF] Environmental and Low Temperature Geochemistry | Semantic ScholarSeveral Ce-carbonate, -phosphate, -silicate, and - hydr oxide minerals have been historically mined and processed for pharmaceutical uses and industrial applications. Of all Ce minerals, cerium dioxide has received much attention in the global nanotechnology market due to their useful applications for catalysts, fuel cells, and fuel additives. A recent mass flow modeling study predicted that a major source of CeO 2 nanoparticles from industrial processing plants e. The environmental fate of CeO 2 nanoparticles is highly dependent on its physcochemical properties in low temperature geochemical environment. Interestingly, there has been contradicting reports about the toxicological effects of CeO 2 nanoparticles, acting as either an antioxidant or reactive oxygen species production-inducing agent.

Suspended sediments from 34 major rivers geographically widespread and 36 glacial meltwater streams have been examined for their variations in different operationally-defined iron fractions; Fe HR iron oxides soluble in dithionite , Fe PR iron soluble in boiling HCl but not in dithionite and Fe U total iron less that soluble in boiling HCl.

While basic aqueous chemistry principles, including acid-base equilibrium, reduction-oxidation reactions, and solubility, are the driving force behind most phenomena, interconnections between geology, hydrology, biology, and atmospheric science require an interdisciplinary approach to investigating these systems. Low-temperature geochemistry is a broad field, but major areas of study include mineral precipitation, chemical weathering, soil chemistry, sedimentary processes and diagenesis, biogeochemical cycles, and contaminant transport. In general, geochemistry can be defined as the study of the chemical composition and changes of the earth and other celestial bodies. We further define the subject based upon the overall geologic environment, pressure, or temperature Skip to main content Skip to table of contents. Encyclopedia of Geochemistry Edition.

He received a Ph. His research interests fall into two main areas: 1 understanding the geological and mineralogical controls on trace element speciation, particularly the occurrence and mobility of arsenic and uranium in bedrock aquifers; and 2 the temporal evolution of soils in the tropics, with emphasis on mechanisms and rates of mineralogical reactions, nutrient cycling and application of soil geochemical analysis to correlation and geological interpretation.
