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,...

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...

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...

Association of hydrophobic organic compounds with dissolved soil organic carbon

Creator:

Ochs, Michael

Abstract:

Volatile hydrophobic compounds (HOCs) brought into soil and sediment systems represent a serious threat to the environment. Dissolved organic carbon (DOC) may exert an important influence over the total aqueous solubility and mobility of organic pollutants through their incorporation into micelles or the formation of soluble complexes. To date, however,...

Dynamics of organic matter production and degradation during coastal diatom blooms

Creator:

Wetz, Michael S.

Abstract:

Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...

Atmospheric transport of anthropogenic semi-volatile organic compounds to the Olympic Peninsula of Washington State

Creator:

Killin, Robert K.

Abstract:

Ambient high-volume (hi-vol) air samples were collected between March 15th and May 30th 2002, at Cheeka Peak Observatory (CPO), located on the tip of the Olympic Peninsula, Washington State. This sampling campaign was in conjunction with the 2002 Inter-Continental Transport and Chemical Transformation (ITCT 2K2) Campaign and the Photochemical Ozone...

Semi-volatile organic compounds as molecular markers for atmospheric and ecosystem transport

Creator:

Genualdi, Susan A.

Abstract:

The use of semi-volatile organic compounds (SOCs) as molecular markers to identify the contributions of regional and long-range atmospheric transport, as well as current and historic sources, and contaminant deposition in remote ecosystems of the Western U.S. was investigated. Trans-Pacific air masses influenced by Siberian biomass burning events had elevated...

Copper Speciation in Wastewater-Impacted Surface Waters

Creator:

Mosbrucker, Ariel M.

Abstract:

This study investigates the relationship between total and ionic copper in samples taken from the Tualatin River and wastewater treatment facilities (WWTFs) that discharge into the Tualatin River. Copper speciation was analyzed by determining conditional stability constants and densities of copper binding ligands on the dissolved organic matter (DOM) in...

Assessment of exposure and response to atmospherically-derived contaminants in U.S. Arctic freshwater fish

Creator:

Allen-Gil, Susan M.

Abstract:

The Arctic has long been considered to be a pristine environment, far from population centers and pollution sources. The detection of synthetic organochlorine compounds in various elements of the Arctic food web has confirmed the global dispersion of pollutants, particularly of persistent compounds such as organochlorines and heavy metals. Levels...
