Application of biomarker compounds as tracers for sources and fates of natural and anthropogenic organic matter in the environment

Creator:: Oros, Daniel R.
Abstract:: Determination of the source and fate of natural (higher plant lipids, marine lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived hydrocarbons and oxygenated compounds in the environment was accomplished using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) to characterize or identify molecular biomarkers to be utilized as tracers....

Tracking semi-volatile organic pollutants in remote lake systems

Creator:: Usenko, Sascha
Abstract:: SOCs volatility and persistence properties cause many SOCs to become ubiquitous in the environment as well as accumulate in areas with lower temperatures such as polar or orographic regions. Many anthropogenic SOCs pose a serious risk to human and ecosystem health because of their persistent, bioaccumulative, and toxic properties in...

Characterization, chemodynamics and environmental impact assessment of leachates from complex organic materials

Creator:: Aboul-Kassim, Tarek A. T.
Abstract:: More than 65,000 organic chemicals are currently in commercial production with approximately 1000 added each year. Many chemicals are released into the environment as organic mixtures derived from complex hazardous or solid wastes. Of these, more than 1000 chemicals are of environmental concern because of their production quantities, toxicity, persistence,...

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...

Polar organic compounds as tracers of environmental processes

Creator:: Medeiros, Patricia Matheus de
Abstract:: Sources of polar/water-soluble organic compounds conjunctly with apolar biomarkers were characterized in natural organic matter. This multi-biomarker approach was accomplished by a simple analytical method consisting of extraction with dichloromethane:methanol (2:1, v/v), silylation and analysis by gaschromatography- mass spectrometry (GC-MS). Polar and apolar biomarkers, derived mainly from higher plants and...

The synthesis and chemistry of strained bicyclic systems

Creator:: Scerbo, Louis
Abstract:: A facile route to bicyclo(2.1.1)hexanes was developed involving the intramolecular photocyclization of 1, 5-hexadien-3-one to bicyclo(2.1.1)hexan-2-one. A study of the chemistry of bicyclo-(2.1.1)hexan-2-one was undertaken. Deuterium exchange and borohydride reduction demonstrated the strain present in the ketone. Further evidence was obtained from the failure to introduce substituents alpha to the...

The synthesis of nonactic acid

Creator:: Arco, Manuel Jose
Abstract:: Alkylation of propylene oxide with 2-lithiofuran gave alcohol I, which was smoothly converted to acetylfuran II. hydrogenation of II over rhodium on charcoal followed by Jones' oxidation afforded ketone III. Further transformation into IV was accomplished via a Wittig reaction followed by saponification with methanolic sodium hydroxide. Hydroboration of the...
