    Uptake of multielements by corn from fly ash-compost amended soil (1994)
    Springer
    Water, air & soil pollution 72 (1994), S. 285-295 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Fly ash was collected from a coal-fired power plant in and near the U.S. Department of Energy Savannah River Site to study the feasibility of the application of fly ash compost mixture to soils for the availability and uptake of various elements by corn (Zea mays L.). The crop was grown in potted Ogeechee sandy loam soil using eight treatments: soil alone, soil amended with 15% compost, and soil amended with 2, 5, 10, 15, 20 and 25% of fly ash-amended compost. It was observed that 20–25% fly ash and compost soil ratio treatments generally increased plant growth and the yield. The plant uptake of K, Mn, and Cu increased with increasing percentages (2–25%) of fly ash+compost: soil ratios. The total content of K in plants was positively correlated with the dry matter yield of corn. This study indicates that the application of fly ash blended with compost to soil is beneficial to corn production without causing any deleterious effects on plant growth and plant composition.

    Retention and release of selected major and minor metals by the altamaha river marsh ecosystem (1985)
    Springer
    Water, air & soil pollution 25 (1985), S. 195-206 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The retention and release of two major metals, K and Mg, and two minor metals, Zn and Mn, bySpartina alterniflora andSpartina cynosuroides salt marsh ecosystems along the terminal course of Altamaha river were investigated. The metal content in plant and soil samples collected from the two sites was measured periodically. A rectangular box-model of the ecosystem (1 m × 1 m × 0.5 m) was used to normalize the metal content of all materials in g m−3. The net annual retention or release of the metals in the ecosystem was computed from the periodic changes in the metal content of the live plant, dead tissues and of the soil (HCI extractable). The system populated byS. alterniflora releases 1.53 g m−3 of Mn while that covered byS. cynosuroides delivers 17.18 g m−3 of Mn to the river. Zinc is retained at the annual rate of 0.17 g m−3 by the former system and 1.21 g m−3 by the latter. The annual retention rate of K and Mg byS. alterniflora system is 71.76 g m−3 and 522.08 g m−3 respectively, whileS. cynosuroides system retains annually 171.0 g m−3 of K and 499.54 g m−3 of Mg.

    Fractionation and transport of nutrients among coal ash residues and in soil covered with fly ash-amended organic compost (1993)
    Springer
    Water, air & soil pollution 69 (1993), S. 209-216

    Notes: Abstract Coal-fired power plants generate different types of ash residues and discharge small particles and vapors to the atmosphere. The ash residues which account for the major part of the byproducts are collected and stored as bottom ash, boiler ash, and fly ash, weathered ash and ash in lagoon. Analysis of water extracts of these residues will reveal how the nutrients are distributed in these residues and transported to aquatic systems. Equally interesting is the study of the downward movement of nutrients in soil treated with fly ash-amended organic compost when used as a manure for agricultural crops. In this work water extracts of different types of ash residues and eluates from descending ports of an experimental column of soil at different depths were also analyzed. Our results showed that there is considerable difference in the efficiency of removal and deposition of nutrients on different residues collected from the power plant and stored outside. Bottom ash was found to accumulate K, N, and S while Ca is enriched in ash from lagoon. Transition metals such as Zn, Mn, and Cu are concentrated in weathered ash. The concentration of most of the nutrients was found to decrease, in column experiments, as a function of depth and level to a depth of 80 cm.

    Trace element release from estuarine sediments of South Mosquito Lagoon near Kennedy Space Center (1979)

    Notes: Abstract Analytical partitioning of four trace metals in estuarine sediments collected from eight sites in South Mosquito Lagoon near Kennedy Space Center, in terms of four different categories was accomplished using four different extraction techniques. The concentrations of the four trace metals, Zn, Mn, Cd, and Cu, released in interstitial water extract, 1 N ammonium acetate extract, conc. HCl extract and fusion extract of sediments as well as their concentrations in water samples collected from the same location were determined using flame atomic absorption technique. From the analytical results the percentages of total amount of each metal distributed among four different categories, interstitial water phase, acetate extractable, acid extractable and detrital crystalline material, were determined. Our results suggest that analytical partitioning of trace metals in estuarine sediments may be used to study the mechanism of incorporation of trace metals with sediments from natural waters. A correlation between the seasonal variation in the concentration of acetate extractable trace metals in the sediment and similar variation in their concentration in water was observed. A mechanism for the release of trace metals from estuarine sediments to natural water is also suggested.

    Notes: Abstract The pH, conductivity and the concentration of 15 selected elements were measured in the water extracts of five coal fly ash samples collected from Savannah River Site (SRS) and one from South Carolina Electric and Gas (SCE & G) power plant. This work was intended to study the differences in the physico-chemical properties of SRS fly ash samples relative to those of a reference sample (SCE & G) and to make fly ash-amended composts for agricultural use. Similar analyses were also performed in water extracts of a commercial organic manure, ‘Gotta Grow’, that was composted with one of the fly ash samples (SRS 484-D) in different proportions. Our results show that fly ash samples used in this study differ considerably in pH, conductivity, and elemental composition and that transition metals appear to bind more tightly on smaller particles than on larger ones. The elementally rich manure, ‘Gotta Grow’, is not suitable to study the effects of fly ash on the elemental release from fly ash-amended composts. Low grade or home-made organic composts are being investigated as possible choice for making ly ash-amended composts.

    Notes: Abstract The solubility, solubility product and the thermodynamic functions for the CeF3−H2O system have been measured using the radiometric, conductometric and potentiometric techniques. The radiometric values for the solubility and solubility product, the lowest and more acceptable for reasons cited in previous papers, are 3.14·10−5 M and 2.17·10−17 respectively. The enthalpy change measured by the conductometric method is almost twice as that obtained by potentiometric method due to abnormal conductances registered at higher temperatures. The average values for ΔHo and ΔGo and ΔSo at 298 K are 53.0±17.4, 91.7±4.0 and −129.7±58.2 KJ·mol−1 respectively. The positive values for ΔHo and ΔGo and the negative value for ΔSo are indicative of the low solubility of this salt in water. The stability constants for the mono- and difluoride complexes of Ce(III) have been determined potentiometrically using unsaturated solution mixtures of Ce(III) and F−. These values for CeF+ and CeF 2 + are 997±98 and (1.03±0.44)·105, respectively. Studies on pH dependence of the solubility shows that the solubility reaches a minimum value at a pH of about 3.2.
