I., 1961, Geochemical and hydrodynamic conditions of epigenetic uranium mineralization in petroleum-water zones: Geochemistry, no. 2, p. 107-120. C) Purpose: examine the relationship between uranium deposits and organic matter. Methods: literature review. Results: uranium precipitation occurs when uraniferous groundwater penetrates petroleum reservoirs. Water Eh drops from 500-250 mv to as low as -400 mv, the uranium is reduced and precipitated. The waters must be enriched in U, possibly up to n-10 g/liter. Oxidizing conditions are favorable to enrichment. 2 2. A) Gen. Cat.-Behavior of actinides in geomedia B) Naumov, G. B., 1961, Some physicochemical characteristics of the behavior of uranium in hydrothermal solutions: Geochemistry, n. 2, p. 127-147. C) Purpose: examine conditions of uranium ore formation. Methods: literature review. Results: C02, F, S, Cl, and some form of silica are important components of U-bearing hydrothermal solutions. Temperatures range from 25 0C to 3000C, pressures were less than 1000 atm., and the solutions could not have been strongly acid. U may be transported as complicated complex ions, most probably carbonates or fluorides. Most uranium is transported as U-VI and deposited as U-IV. 3 3. A) Gen.

C) Purpose: examine control of Eh on U-mineralization. Methods: use of LP-5 potentiometer to measure Eh. Results: uranium and pyrite contents of the rocks were directly proportional to the change in Eh(AEh) in solution. The greatest &Eh occurred in rocks that contained organic matter. Reduced rocks showed hEh ranging from 15 to 30 mv. U content may be small despite a large AEh if rock permeability is low. 4 4 . A) Gen. Cat.--Behavior of actinides in geomedia B) Bloxam, T.

C) Purpose: obtain data on abundance of U and Th, and their relationship to P and C, in black shales. Methods: gamma spectrometry, XRD, flame spectrometry, wet chemical analyses. Results: there is a close, linear relationship between U and organic C. Th/U - 3.2 in these rocks; average U - 4.0 ppm, average Th - 12.3 ppm. Like U and organic C, Th increases linearly with K. Both Th and K have inverse relationships with U. 5 5. A) Gen. Cat.--Hydrothermal alteration or Behavior of actinides in geomedia B) Kovalenko, V. I.; Krinberg, I. A.; Mironov, V. P.; Selivanova, G.

C) Purpose: examine behavior of actinides, Na and Th during metasomatism. Methods: spectrographic analyses; other methods not discussed. Results: the contents of all 4 elements increase from the granite to the quartz-albite metasomatic zone. Decreasing alkalinity of the metasomatic facies favors enrichment of U relative to Th and Nb with respect to Ta. U/Th is higher in alaskites with secondary biotite as opposed to secondary metasomatic riebeckite. 6 6 . A) Gen. Cat.--Behavior of actinides in geomedia B) Serebryakova, M.

C) Purpose: experimentally.determine forms of U in waters. Methods: dialysis, ion exchange, electrodialysis. Results: colloidal U is absent in the test samples. 95-98% of the uranium occurs as anionic species, specifically, EU02(C03)2(H20)2j2 [U02(CO3 )3J , and U020H+. All samples had a high carbonate ion content (C03/U X 3). Cationic UO2OH+ accounted for only 2% of the uranium. 7 7 . A) Gen. Cat.-Behavior of actinides in geomedia B) Cherdyntsev, V.

Methods: literature review, alpha spectrometry. Results: neutron capture by 238U and an unknown heavy element (Z - 84-92.94) are the 2 sources of Pu-239 in nature. 39Pu tends to be enriched in waters relative to U-minerals (239Pu/ 238U - 10 7 in water and 10 in U ores). 239Pu has been identified insphene, molybdenite, magnetite, apatite, and zircon in an ore vein, and also in Fe-carbonates and exhaled gases of submarine volcanics. - 8 8 .

C) Purpose: examine accumulation of U in peat bogs as a possible mechanism of U mineralization. Methods: wet chemical methods, dialysis. Results: these U accumulations have formed in an area of normal U concentrations in bedrock and only slightly above background in water. U fixation in peat is a combination of adsorption and reduction of U. These 2 processes result in a stable association between U and organic matter. 10 10. A) Gen.

  • Toxicological Profile for Silica
    SILICA 208 CHAPTER 5. POTENTIAL FOR HUMAN EXPOSURE 5.1 OVERVIEW Silica has been identified in at least 37 of the 1,854 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (ATSDR 2017). However, the number of sites in which silica has been evaluated is not known. The number of sites in each state is shown in Figure 5-1. Figure 5-1. Number of NPL Sites with Silica Contamination Crystalline Silica • c-Silica is ubiquitous and widespread in the environment, primarily in the form of quartz. Other predominant forms include cristobalite and tridymite. • Sand, gravel, and quartz crystal are the predominant commercial product categories for c-silica. • c-Silica enters environmental media naturally through the weathering of rocks and minerals and anthropogenic releases of c-silica in the form of air emissions (e.g., industrial quarrying and mining, metallurgic manufacturing, power plant emissions) or use in water filtration (quartz sand). SILICA 209 5. POTENTIAL FOR HUMAN EXPOSURE • c-Silica undergoes atmospheric transport as a fractional component of particulate emissions, is virtually insoluble in water and generally settles into sediment, and remains unchanged in soil. • c-Silica is present in air and water; therefore, the general population will be exposed to c-silica by inhalation of ambient air and ingestion of water. • Inhalation exposure is the most important route of exposure to c-silica compounds due to the development of adverse effects from inhaled c-silica in occupational settings. • Individuals with potentially high exposures include workers with occupational exposure to c-silica, which occurs during the mining and processing of metals, nonmetals, and coal, and in many other industries.

  • Toxicological Profile for Silica Released for Public Comment in 2017
    Toxicological Profile for Silica September 2019 SILICA ii DISCLAIMER Use of trade names is for identification only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry, the Public Health Service, or the U.S. Department of Health and Human Services. SILICA iii FOREWORD This toxicological profile is prepared in accordance with guidelines* developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for these toxic substances described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The focus of the profiles is on health and toxicologic information; therefore, each toxicological profile begins with a relevance to public health discussion which would allow a public health professional to make a real-time determination of whether the presence of a particular substance in the environment poses a potential threat to human health. The adequacy of information to determine a substance's health

High-resolution transmission electron 28 microscopy and electron diffraction demonstrate that sub-micron and nano-scale keatite 29 precipitates have a definite crystallographic relationship with the host pyroxene (diopside = 30 ~Di89) CPX (100) ║keatite (100) and CPX (010) ║keatite (001). Clinopyroxene provides a 31 template for keatite nucleation due to the close structural relationship and excellent lattice match 32 between the diopside and keatite. We propose that keatite micro-precipitates are formed in 33 localized low pressure micro-environments produced as a result of exsolution of extra silica and 34 vacancies held within UHP host diopside and stabilized by the pyroxene lattice. Low density 35 metastable keatite and its relationship to the host pyroxene likely reflects the important influence 36 of pyroxene/precipitate interfacial energy on the micro- and nano-scales in controlling the nature 37 of exsolved phases in exhumed UHP minerals. 38 Keywords: HRTEM, ultrahigh-pressure (UHP), diopside, keatite, silica exsolution, epitaxial 39 growth 40 1.

M.S.M.S.E Department of Mechanical and Material Science Engineering, Wright State University, 2020. Stabilization of β-Cristobalite in the SiO2-AlPO4-BPO4 System. Fused silica (silica glass) is transparent in the optical and near-infrared and has a low dielectric constant, making it suitable as a window material for radio frequency radiation. However, at high temperatures (>1100C), fused silica will easily creep and lose dimensional stability. Crystallized silica is much more creep resistant than fused silica. Silica crystallizes to many different structures including quartz, tridymite, and α- and β cristobalite. The only cubic polymorph, which is suitable for both optical and radio frequency transmission in polycrystalline form, is β -cristobalite.
