Book Synopsis The Impacts of Legacy Mining Operation on Inorganic Arsenic Bioaccumulation and Exposure in Yellowknife, Northwest Territories, Canada by : Claudia Tanamal
Download or read book The Impacts of Legacy Mining Operation on Inorganic Arsenic Bioaccumulation and Exposure in Yellowknife, Northwest Territories, Canada written by Claudia Tanamal and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic transfers and toxicology are important topics of research and a public health concern because arsenicosis affects millions of people worldwide every year. One of the most significant sources of arsenic in the environment is industrial wastes, such as by-products of mining operation. In Yellowknife, Northwest Territories, Canada, there were two large gold mines-Giant Mine and Con Mine, along with dozens of small-scale mines. The combined by-product of emission from these roasters might have contributed to high concentrations of arsenic found in the city. This thesis presents the results of two related studies to address the environmental health concern: (1) to investigate the arsenic transfers and arsenic species accumulation in freshwater food webs near large legacy mining operations in Yellowknife, and (2) to assess the long-term health risk of inorganic arsenic exposure from the consumption of fish in Yellowknife among the general residents and the Yellowknives Dene First Nation. We found that inorganic arsenic is biominified in food webs (i.e. inorganic arsenic concentrations diminish at higher trophic positions relative to lower trophic positions). Higher-trophic organisms have low inorganic arsenic concentrations in tissue due to biotransformation of inorganic arsenic to non-toxic organic arsenobetaine, and effective elimination of arsenic from their tissue. The trophic positions of freshwater organisms can be used to predict the range of arsenic concentrations and its species composition, accounting for more than 80% of variance. Dietary study results show that the Yellowknives Dene First Nation consumed significantly more fish in their diets (adults: 19 g/day, children: 9 g/day) compared to the general residents of Yellowknife (adults: 9 g/day, children: 5 g/day). Our probabilistic risk assessments showed no significant long-term non-carcinogenic and carcinogenic health risks of inorganic arsenic exposure from fish consumption for the majority of Yellowknife residents, but elevated cancer risks among the adult heavy fish consumers in Yellowknife. However, our data suggested that the residents of Yellowknife were not exposed to higher cancer risks from inorganic exposure compared to the general population in Canada. Therefore, due to fish health benefits and the values associated with its consumption, fish should continue to be a major source of sustenance in Yellowknife.

Book Synopsis Applied Mineralogy in the Mining Industry by : W. Petruk
Download or read book Applied Mineralogy in the Mining Industry written by W. Petruk and published by Elsevier. This book was released on 2000-11-29 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.

Book Synopsis Hazardous Metals in the Environment by : M. Stoeppler
Download or read book Hazardous Metals in the Environment written by M. Stoeppler and published by Elsevier. This book was released on 1992-04-13 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: The execution of detailed studies on the fate and levels of hazardous elements in the environment, foodstuffs and in human beings has become a major task in environmental research and especially in analytical chemistry. This has led to a demand to develop new methodology and optimize that already in use. The book offers the reader a general introduction to the problem areas that are currently being tackled, followed by chapters on sampling and sample preservation, strategies and applications of the archiving of selected representative specimens for long-term storage in environmental specimen banks. This is supplemented by the example of wine as a preserved - frequently, already historical - specimen which clearly reflects technological changes over time. The following chapters review sample treatment, present an overview on the most frequently and successfully applied trace analytical methods for metals and metal compounds, and introduce the increasingly important methods for identifying and quantifying metal species in sediments and soils (speciation). The chapters in the second part of the book provide data on analytical methods for determining the levels of toxicologically, ecotoxicologically and ecologically important elements in environmental and biological materials, including information on the separation and quantification of chemical and organomatallic species. The elements treated are aluminium, arsenic, cadmium, chromium, cobalt, lead, mercury, nickel, selenium and thallium. The final chapter treats quality assurance and the importance of the continuous use of appropriate reference materials to avoid erroneous results.

Book Synopsis Mining North America by : John R. McNeill
Download or read book Mining North America written by John R. McNeill and published by Univ of California Press. This book was released on 2017-07-03 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Over the past five hundred years, North Americans have increasingly turned to mining to produce many of their basic social and cultural objects. From cell phones to cars and roadways, metal pots to wall tile and even talcum powder, minerals products have become central to modern North American life. As this process has unfolded, mining has also indelibly shaped the natural world and North Americans' relationship with it. Mountains have been honeycombed, rivers poisoned, and forests leveled. The effects of these environmental transformations have fallen unevenly across North American societies. Mining North America examines these developments. Drawing on the work of scholars from Mexico, the United States, and Canada, this book explores how mining has shaped North America over the last half millennium. It covers an array of minerals and geographies while seeking to draw mining into the core debates that animate North American environmental history generally. Taken together, the authors' contributions make a powerful case for the centrality of mining in forging North American environments and societies"--Provided by publisher.
