Characterizing Waterborne Lead in Private Water Systems
… and time series sampling), three patterns of waterborne lead release were identified: no elevated lead or lead elevated in the first draw of water only (Type I), erratic spikes of particulate lead mobilized from plumbing during periods of water use (Type II), and sustained detectable lead …

Investigation of Waterborne Epoxies for E-Glass Composites
… due partially to the potential application as a waterborne replacement for solvent cast epoxies in E-glass laminated printed circuit boards. This research has revealed that the viscoelastic behavior of the cured epoxy is altered when serving as the matrix in a glass composite. The additional …

Surface Enhanced Raman Spectroscopy as a Tool for Waterborne Pathogen Testing
The development of a waterborne pathogen detection method that is rapid, multiplex, sensitive, and specific, would be of great assistance for water treatment facilities and would help protect water consumers from harmful pathogens. Here we have utilized surface enhanced Raman spectroscopy (SERS) in …

A Machine-Learning Based Approach to Predicting Waterborne Disease Outbreaks Caused by Hurricanes
… hurricanes and winter storms worldwide. Waterborne diseases, resulting from flood-related impacts, affect public health and are of major concern for society. Previous research studies have highlighted a statistically significant linear correlation between waterborne diseases and climate …

Investigation of Adhesive and Electrical Performance of Waterborne Epoxies for Interlayer Dielectric Material
… primary differences between the solventborne and waterborne epoxy printed circuit board (PCB) impregnating resins arise from the distinct physical compositions and drying characteristics of the polymer solution and the latex emulsion. The presence of residual surfactant from the waterborne epoxy …

Effects of ibuprofen on Rainbow Trout (Oncorhynchus mykiss) following acute and chronic waterborne exposures
… (EROD) activity were evaluated following waterborne ibuprofen exposure of trout to 1 and 10 mg/L in the acute exposure and 1, 32 and 1000 μg/L in the chronic exposure, along with an experimental control, E2 control of 1000 μg/L and an E2-ibuprofen mixed treatment. Ibuprofen did not inhibit …

Environmentally friendly hybrid coatings for corrosion protection: silane based pre-treatments and nanostructured waterborne coatings
… and to modify the inner structure of UV curable waterborne organic coatings. In the first part of this thesis thin (hundreds of nanometers) sol-gel films consisting of an experimental mixture of hybrid silicon alkoxides molecules were applied onto aluminium and hot dip galvanized (HDG) steel for …

Cardiac, ventilatory and metabolic responses of two ecologically distinct species of fish to waterborne cyanide
… to a steadily increasing concentration of waterborne cyanide selected to produce death in 8-9 hours for each species. The lethal cyanide concentration for the bullheads was an order of magnitude higher than for trout. Trout developed an immediate and gradually increasing bradycardia …

Waves of communication: Metabolomics describe the nature and role of waterborne cues in the marine environment
Waterborne cues are important tools for signaling in the marine environment. Despite decades of dedicated research, we know little about the chemical nature of these cues and of the physiological response by individuals that detect the cues. Using nuclear magnetic resonance spectroscopy- and mass …

Investigating proteomic profiles of rainbow trout (oncorhynchus mykiss) kidney and liver tissues exposed to low concentrations of waterborne nickel
Nickel has become a component of natural freshwater that may pose serious ecological risks to aquatic wildlife. Due to Canada’s significant presence in producing and exporting nickel, the country has the opportunity to negatively impact aquatic watersheds and the surrounding environment. We …

Investigating proteomic profiles of skin mucus and blood plasma of rainbow trout (Oncorhynchus mykiss) exposed to low concentrations of waterborne nickel
The Ontario Ring of Fire located in the James Bay Lowlands is a nickel rich ore with ongoing mining proposals. This raises the possibility of nickel contamination in one of Ontario’s most precious freshwater regions and peatlands. However, impacts of nickel exposure on freshwater fish species …

Knowledge, Attitudes, And Practices Regarding Waterborne Diseases And Water Purification Among A Selected Rural Community in Vhembe District, Limpopo Province, South Africa
Waterborne infections pose a significant global public health threat, contributing to ap-proximately 4 billion diarrhoea cases and 1.8 million deaths annually. In South Africa, recent cholera outbreaks have highlighted the need for improved community awareness and preparedness regarding waterborne …
