Quantification of C60 Particle Characteristics in Environmentally Relevant Aqueous Systems

Creator:: Adlong, Michelle R.
Abstract:: The production of the fullerene C60 and its emerging applications in consumer products imply its ultimate release to the environment. Due to the molecule’s relative novelty, the aqueous characteristics of C60 have not been fully assessed, though it may potentially harm human or ecological health. C60 is highly insoluble in...

Evaluation of Apatite II™ for removal of copper and zinc from highway stormwater runoff : laboratory and field experiments

Creator:: Provolt, Justin J.
Abstract:: Current best management practices (BMPs) for stormwater treatment are not able to adequately remove heavy metals to levels which do not adversely affect aquatic life. Copper is commonly found in highway stormwater runoff, with the primary source being brake pad wear. Copper is of particular concern due to inhibitory effects...

Heteroaggregation between citrate-stabilized gold nanoparticles and hematite colloids : mechanisms and quantification of nanoparticle-colloid interactions

Creator:: Smith, Brian M.
Abstract:: Understanding the aggregation behavior of engineered nanomaterials (ENMs) in aqueous environments is essential to understanding their fate, transport, and toxicity. Because naturally occurring colloids will likely be present at much higher concentrations than ENMs in environmental systems, heteroaggregation and attachment with these natural colloids could significantly influence ENM fate and...

Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

Creator:: Pike, Daniel J.
Abstract:: Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...

Evaluation of copper removal from stormwater runoff using compost and Apatite II™

Creator:: Silvertooth, Jason R.
Abstract:: Low concentrations of dissolved copper have proven to be harmful to a number of aquatic organisms, with recent research highlighting detrimental effects to endangered salmonid species. Stormwater runoff can represent a significant source of copper to surface waters, necessitating cost-effective alternatives to current stormwater best management practices (BMPs). This study...

Characterization of Biochar for Use in Treating Copper (II) Polluted Stormwater

Creator:: Gerould, Joy-Marie Danielle
Abstract:: Recent studies have discovered that salmon, specifically juvenile Coho Salmon, have their olfactory senses inhibited by the presence of low concentrations of copper concentrations at very low concentrations. Much of this copper is deposited on roadways by car brake pads during their use. The copper is carried with stormwater into...

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...

The Effects of UV Irradiation on the Biosorption of Titanium Dioxide Nanoparticles to Heterotrophic Biomass

Creator:: Young, William M.
Abstract:: The production of titanium dioxide (TiO2) nanoparticles has increased significantly in the past decades, which has generated concern due to their known toxicity in the environment. As a result of the production, use and disposal of productions containing TiO2, TiO2 nanoparticles are often received by wastewater treatment facilities. The adsorption...

Comparison of Aqueous Cu⁺², Pb⁺², and Zn⁺² Adsorption with Pyrolyzed Hazelnut Shells and a Commercially Produced High-Carbon Fly Ash

Creator:: Steigerwald, Jessica Marie
Abstract:: Contamination of stormwater with Cu⁺², Pb⁺², and Zn⁺² has become an important issue with recognition of the neurotoxic effects of these metal ions on aquatic life. Low levels of aqueous Cu⁺² disrupt olfactory functioning in endangered Pacific Northwest salmon, decreasing their ability to avoid predation. One common solution is stormwater...

Quantification of Copper Speciation in Pulp and Paper Wastewater and Implications for the Biotic Ligand Model

Creator:: Mitzel, Joseph M.
Abstract:: The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...
