Mercury Pollution - - Bog - Taylor & Francis Ltd - Plusbog.dk

Mercury Pollution - - Bog - Taylor & Francis Ltd - Plusbog.dk

How does mercury get out of the ground and into our food? Is tuna safe to eat? What was the Minamata Disaster? Mercury Pollution: A Transdisciplinary Treatment addresses these questions and more. The editors weave interdisciplinary threads into a tapestry that presents a more complete picture of the effects of mercury pollution and provides new ways to think about the environment. The remarkable features that make mercury so useful—and poisonous—have given rise to many stories laid out in rich objective detail, carefully detailing medical, epidemiological, or historical insight, but sidestepping the human experience. A technically rich book that only touches on the human consequences of mercury poisoning cannot fully portray the anguish, confusion, and painful deaths that are the consequence of mercury pollution. Therefore, the editors purposely step out of the conventional scientific framework for discussing mercury pollution to explore the wider human experience. This book clarifies how we are all connected to mercury, how we absorb it through the food we eat and the air we breathe, and how we release it as a consequence of our new technologies. It tackles interesting environmental issues without being overly technical and uses mercury as a case study and model for studying environmental problems. The book uses discussions of the issues surrounding mercury pollution to illustrate how an interdisciplinary vantage is necessary to solve environmental problems.

Metal Toxicology Handbook - - Bog - Taylor & Francis Ltd - Plusbog.dk

Metal Toxicology Handbook - - Bog - Taylor & Francis Ltd - Plusbog.dk

Heavy metals and metalloids, singly or in combination, induce toxic manifestations either through acute or chronic pathology. In particular, long-term chronic exposure to diverse heavy metals and metalloids to humans and animals can lead to numerous physical, muscular, neurological, nephrological, and diverse degenerative diseases and dysfunctions, including multiple sclerosis, muscular dystrophy, Parkinson’s and Alzheimer’s diseases, cardiovascular disorders, and several others. Recognized heavy metals such as lead, mercury, arsenic, cadmium, thallium, and hexavalent chromium are known for enormous toxicity. The immediate vital signs of acute heavy metal exposure include nausea, vomiting, diarrhea, and acute abdominal pain. Mercury has been identified as the most toxic heavy metal, and mercury poisoning is known as acrodynia or pink disease. Similarly, lead, another toxic heavy metal, was at one time an integral part of painting. Metal Toxicology Handbook further explains and discusses the varying attributes of metals, discussing toxicity, safety, and proper human utilization of metals. Beginning with a broad overview of metals, metalloids, redox biology, and neurodegeneration and going further into the roles, benefits, and toxicity of metals with each section, the text contains 28 chapters from eminent researchers and scientists in their respective fields and is a must-have for anyone researching the potential toxicity in metals. Key Features Discusses the pathology of metal toxicity Highlights the benefits of metals Explains the mechanism and salient features of restoring metabolic homeostasis Highlights dose-dependent beneficial and adverse effects of vanadium safety and toxicity The initial introductory section provides a broad overview of metals, metalloids, redox biology, and neurodegeneration. The second section discusses the pathology of metal toxicity in two chapters, while the third section highlights the mechanism and salient features of restoring metabolic homeostasis in two chapters. The fourth section demonstrates the aspect of radionuclides toxicity. In a change of pace, the fifth section discusses the benefits of metals in four chapters. The sixth section, titled "Toxic Manifestations by Diverse Heavy Metals and Metalloids," provides fourteen chapters that discuss the toxicological mechanism and manifestation of individual metals. The editors have crafted a commentary titled "A Treatise on Metal Toxicity" and summarized a vivid scenario of metal toxicity and its consequences.

Heavy Metals in the Environment - - Bog - Taylor & Francis Ltd - Plusbog.dk

Heavy Metals in the Environment - - Bog - Taylor & Francis Ltd - Plusbog.dk

A successful modern heavy metal control program for any industry will include not only traditional water pollution control, but also air pollution control, soil conservation, site remediation, groundwater protection, public health management, solid waste disposal, and combined industrial-municipal heavy metal waste management. In fact, it should be a total environmental control program. Comprehensive in scope, Heavy Metals in the Environment provides technical and economical information on the development of a feasible total heavy metal control program that can benefit industry and local municipalities. The book discusses the importance and contamination of metals such as lead, chromium, cadmium, zinc, copper, nickel, iron, and mercury. It covers important research of metals in the environment, the processes and mechanisms for metals control and removal, the environmental behavior and effects of engineered metal and metal oxide nanoparticles, environmental geochemistry of high arsenic aquifer systems, nano-technology applications in metal ion adsorption, biosorption of metals, and heavy metal removal by expopolysaccharide-producing cyanobacteria. The authors delineate technologies for metals treatment and management, metal bearing effluents, metal-contaminated solid wastes, metal finishing industry wastes and brownfield sites, and arsenic-contaminated groundwater streams. They also discuss control, treatment, and management of metal emissions from motor vehicles. The authors reflect the breadth of the field and draw on personal experiences to provide an in-depth presentation of environmental pollution sources, waste characteristics, control technologies, management strategies, facility innovations, process alternatives, costs, case histories, effluent standards, and future trends for each industrial or commercial operation. The methodologies and technologies discussed are directly applicable to the waste management problems that must be met in all industries.
