  • A study of the quantity and distribution of bark debris resulting from log rafting

    Creator:
    Williamson, Kenneth J.
    Abstract:
    A study was conducted to determine the quantity and distribution of bark debris resulting from log rafting. Three distinct problems were studied: (I) the quantity of bark dislodged from the logs while being placed in the rivers and during transport in log rafts; (2) the percentage of the bark that...

  • Continuous synthesis of metal-organic frameworks under high pressure

    Creator:
    Li, Yong J.
    Abstract:
    Metal Organic Framework (MOF) materials, consisting of metal ions with organic linkers, have a functional cavity structure which can be utilized in applications such as catalyst, micro sensing, and gas absorption. Due to MOF materials' selective gas adsorption property, interest in MOF materials has intensified in the last few years,...

  • Biodegradation of chlorinated methanes using a methylotrophic/anaerobic biofilm reactor

    Creator:
    Celeste, Stephen J.
    Abstract:
    Chlorinated low molecular weight solvents have been discovered in a number of the nation's groundwater supplies. Remediation of these aquifers will require some form of treatment. Presently, the dominant treatment method is air stripping which results in transfer of the solvent from the aqueous phase into the atmosphere. Biodegradation is...

  • Effects of chlorinated aliphatic hydrocarbon degradation on the metabolic enzymes in Nitrosomonas europaea

    Creator:
    Fawcett, Kimberly A.
    Abstract:
    The toxic effects of degrading the chlorinated hydrocarbons trichloroethylene (TCE), chloroform (CF) and cis-1,2-dichloroethylene (cis-1,2-DCE) were studied in the bacterium Nitrosomonas europaea. N europaea is an ammonia-oxidizing bacterium that obtains all of its energy from the oxidation of ammonia to nitrite. This metabolic process involves two enzymes, ammonia monooxygenase (AMO)...

  • Aerobic degradation of chlorophenols

    Creator:
    Wang, Gongming
    Abstract:
    Chlorinated phenols are toxic compounds and often released into natural environments from improper disposal or non-point sources. One important factor in assessing the environmental fate and transport is the rates of microbial degradation in soils and natural waters. In this study, eight chlorophenols (4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), 3,4-dichlorophenol (3,4-DCP), 3,5-dichlorophenol...

  • The determination of selected polychlorinated dibenzo-p-dioxins and dibenzofurans in environmental samples from sites associated with the use of chlorophenolic wood preservatives

    Creator:
    Hackett, Murray
    Abstract:
    Polychlorinated dibenzo-p-dioxins (PCDD's) and dibenzofurans (PCDF's) are environmental pollutants associated with the production and use of a number of industrial chemicals. In addition, PCDD's and PCDF's are produced during low temperature combustion of wastes containing polyvinylchloride (PVC), chlorophenols, and a number of other chemical precursors. A significant source of environmental...

  • Environmental Regulations Reconsidered : Identifying Incentives and Barriers to Environmental Performance

    Creator:
    Craig, Kathleen D.
    Abstract:
    Attention has been drawn to the observation that environmental benefits under the current regulatory approaches are diminishing with respect to increased pollution control costs. Regulators have begun to appreciate that while environmental gains can still be achieved under the current command and control system, the most significant environmental gains have...

  • The effect of organic sorbent concentration on sorption kinetics

    Creator:
    Dolan, Mark E.
    Abstract:
    Batch sorption tests were conducted using 3,4-DCP and cellulose triacetate as the sorbate/sorbent pair. Sorbate concentrations in the liquid were sampled with time and analyzed by electron capture detector gas chromatography. Sorption was found to be a two stage process characterized by a rapid initial uptake followed by a extended...

  • Trace metal redistribution in artificial estuarine sediments

    Creator:
    Delphey, Craig Edward
    Abstract:
    The transfer of trace metals within an estuarine system is a complex function of physical and chemical processes unique to that system. Although interactions of metals with individual components has been studied, there has been little investigation of interactions with multiple component systems. Thus to further understand these processes, an...

  • Metal and organic emissions from RDF and large volume contributor combustion

    Creator:
    Lee, Taejin, 1961-
    Abstract:
    The use of municipal refuse (RDF) as fuels has received widespread attention for reason of its energy equivalence and the increasing lack of available landfill sites. The principal obstacle to the construction of combustion facilities is that RDF produces toxic compounds, including heavy metals and such organic compounds as PCDD...
