  • Synthesis, characterization, and analysis of nitroaromatic compounds

    Creator:
    McIntosh, Melissa Luana
    Abstract:
    Nitroaromatic compounds have important chemical applications and can be found in nature as pollution sources. Synthetic nitroaromatic compounds have been used in a variety of materials including explosives, pharmaceuticals, dyes, plastics, and pesticides. These compounds can find their way into the environment through normal or improper disposal methods. Poly-aromatic compounds...

  • Effects of aerosols on the properties of deep convective clouds

    Creator:
    Brown, Daniel A.
    Abstract:
    Aerosols are tiny particles that serve as nuclei for cloud droplet and ice crystal formation. Increases in aerosol concentration lead to clouds with smaller but more numerous droplets. Some recent studies have found evidence that ice crystal size in deep convective clouds is also reduced by elevated aerosol concentrations. In...

  • Trans-Pacific and regional atmospheric transport of anthropogenic semivolatile organic compounds in the western U.S.

    Creator:
    Primbs, Toby
    Abstract:
    The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...

  • Human exposure to polycyclic aromatic hydrocarbons : global cancer risk and metabolism

    Creator:
    Motorykin, Oleksii
    Abstract:
    In recent decades, there has been increased attention on human exposure to, and subsequently toxicity of, Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are widespread organic pollutants and some have been shown to be toxic, carcinogenic and mutagenic. This research was focused on understanding the link between global PAH emissions and lung...

  • Assessment of fluorinated chemicals (FCs) on developmental toxicity in embryonic zebrafish

    Creator:
    Duong, Lisa
    Abstract:
    Fluorinated chemicals (FCs) have been used since the 1950s in many industrial and commercial applications because of their unique properties such as chemical inertness, resistance to heat and their ability to repel water and oils. Concerns regarding potential environmental or human health risk from FCs exposure have emerged due to...

  • Application of nitrogen stable isotopes to identify sources of nutrient pollution : a management tool?

    Creator:
    Redon, Elizabeth A.
    Abstract:
    Nutrient pollution may perhaps be one of the oldest water quality problems and has recently been considered as one of the greatest threats to estuarine and coastal waters. Excessive nutrient loads have had a vast array of impacts on estuarine and coastal ecosystems globally. Direct negative effects include: shading out...

  • From pesticide degradation products to legacy toxicants and emerging contaminants : novel analytical methods, approaches, and modeling

    Creator:
    Forsberg, Norman D.
    Abstract:
    Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...

  • Determination of Trade-offs between Wetland Ecosystem Services in an Agricultural Landscape

    Creator:
    Garrison, Stacey L.
    Abstract:
    Wetland restoration mitigates effects of agricultural development on water quality, flooding, and habitat loss. Multi-objective optimization for wetland locations and sizes has not included objective functions for water quality, hydrology, and habitat in unison, limiting analysis of trade-offs among these ecosystem services. This study establishes two methods to improve the...
