  • 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....

  • 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...
