Characterization of Colloids in Circumneutral Mine Waters Resulting from Pb-Zn Tailings
Natural waters are typically filtered to 0.45 microns in order to discriminate between truly dissolved and non-aqueous phases. Acid is then added to the sample as a preservative, and all measured concentrations are considered ...
Reopening The Book of Nature: Reconceptualizing Nature Through an Environmental Hermeneutic
The idea of nature as a book to be read has a long and rich history, playing an important role in shaping human attitudes toward the natural world. Through the medieval and early modern periods, the world came to be ...
Better Tomorrows from Yesterday’s Mistakes: Creating a Eutrophication Remediation Framework Through a Case Study of Lake Simcoe and Lake Erie Mitigation Strategies
Lake Eutrophication is a rapidly emerging global issue that threatens both human and natural communities. While many attempts at lake remediation have occurred in the past, few have been truly successful. This may be due ...
Agrochemical Use in South Africa: The toxicological and sociological impacts of agrochemicals on susceptible populations in South Africa's agricultural sector
The purpose of this paper is to explore the influences and impacts of South Africa’s use of agrochemicals in its agricultural sector. South Africa has a rich history, and some of those historical influences, such as apartheid ...
Relationships Between Blood Mercury Concentrations and Oxidative Stress in Phalacrocorax auritus
Mercury (Hg) is a widespread contaminant that has been shown to induce adverse health effects in a wide range of organisms. We explored the relationship between total blood Hg concentrations ([Hg]) and oxidative stress ...
Quantitative Structure Activity Relationships for chronic toxicity of alkyl-benz[a]anthracenes to early life-stages Japanese medaka (Oryzias latipes)
Polycyclic aromatic hydrocarbons (PAH) are hydrophobic environmental contaminants known to impact survival and reproduction in fish species. This study tested the toxicity of benz[a]anthracene (B[a]A) and 7-methylbenz[a]anthracene ...
