Book Description
Mercury (Hg) is a global pollutant that knows no environmental boundaries. Even the most stringent control of anthropogenic Hg sources will not eliminate exposure given its ubiquitous presence. Exposure to Hg occurs primarily via the food chain due to MeHg’s accumulation in fish. Latest US statistics indicate that 46 States have fish consumption advisories. In addition, Hg is a common pollutant in hazardous waste sites, with an estimated 3-4 million children living within one mile of at least one of the 1,300+ active hazardous waste sites in the US. The effects on intellectual function in children prenatally exposed to MeHg via maternal fish consumption have been the subject of two on-going major, prospective, longitudinal studies in the Seychelles and the Faroe Islands. It is important to recognize that the risk for MeHg exposure is not limited only to islanders with high fish consumption. This book will provide state-of-the-art information to the graduate student training in toxicology, risk assessors, researchers and medical providers at large. It is aimed to bring the reader up to date on contemporary issues associated with exposure to methylmercury, from its effects on stem cells and neurons to population studies.

Book Description
Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.

Book Description
Mercury is widespread in our environment. Methylmercury, an organic form of mercury, can accumulate in the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Toxic Effects of Mercury intends to facilitate among its readers the understanding of the importance of mercury pollution in the environment and the health consequences associated with exposure to this metal. The knowledge on methylmercury (MeHg) toxicity collected over the years is undoubtedly robust creating an impression all that is to be learnt about this metal has already been accomplished. However, in large measure, past knowledge has merely laid the ground for interesting questions that have yet to be fully addressed and concepts have yet to be deciphered. One of my major goals was to make a valiant attempt to include state-of-the-art information on the mechanisms of mercury toxicity, describing its effects on cultured cellular systems as well as in whole living organisms, starting from the lessons learned from the tragic events in Minamata Bay, Japan. A special focus of the book is on the neurotoxic effects of MeHg. An understanding at the cellular level is necessary to gather information on the structural and functional alterations induced by MeHg and how they possibly become unmasked and evident at the behavioral level, 32 chapters of the book have been organised having these considerations in mind. This book will provide state-of-the-art information to the graduate students training in toxicology, risk assessors, researchers and medical providers at large. It is aimed to bring the readers updated information on contemporary issues associated with exposure to methylmercury, from its effects on stem cells and neurons to population studies. It is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report provides an excellent example of the implications of decisions in the risk assessment process for a larger audience and is written with the hope that the information will provide better understanding of the mercury problems which confront us.

Book Description
Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students.

Book Description
In biochemistry, a metalloprotein is a generic term for a protein that contains a metal cofactor. The metal may be an isolated ion or may be coordinated with a nonprotein organic compound, such as the porphyrin found in hemoproteins. In some cases, the metal is co-coordinated with a side chain of the protein and an inorganic nonmetallic ion. This kind of protein-metal-nonmetal structure is seen in iron-sulfur clusters Metalloproteins deals with all aspects related to the intracellular and extracellular metal-binding proteins, including their structures, properties and functions. The biological roles of metal cations and metal-binding proteins are endless. They are involved in all crucial cellular activities. Many pathological conditions are related to the problematic metal metabolism. Research in metalloprotein-related topics is therefore rapidly growing, and different aspects of metal-binding proteins progressively enter curricula at Universities and even at the High School level on occasion. However, no key resource providing basic, but comprehensible knowledge on this rapidly expanding field exists. The Encyclopedia of Metalloproteins aims to bridge this gap, and will attempt to cover various aspects of metalloprotein/metalloproteomics and will deal with the different issues related to the intracellular and extracellular metal-binding proteins, including their structures, properties and functions. The goal is to cover exhaustively all catalytically and biologically crucial metal ions and to find at least one interacting protein for other metal ions. The Encyclopedia of Metalloproteins will provide a key resource for advanced undergraduate and graduate students, researchers, instructors, and professors interested in protein science, biochemistry, cell biology, and genetics.

Book Description
Assembles international authorities to address contemporary research in metal neurotoxicity. Essential and non-essential metals play an important role in neurodevelopmental and neurodegenerative diseases. Recent developments in understanding the role of metals in the etiology of these disorders have led to rapid growth in clarifying the pathology of some of the most devastating diseases we face and in identifying potential new therapies. Few books or periodicals have been wholly dedicated to the topic of metals, and this collection is intended to serve as a resource for all researchers interested in metals and their role in health and disease.

Book Description
Exposure to toxic chemicalsâ€"in the workplace and at homeâ€"is increasing every day. Human behavior can be affected by such exposure and can give important clues that a person or population is in danger. If we can understand the mechanisms of these changes, we can develop better ways of testing for toxic chemical exposure and, most important, better prevention programs. This volume explores the emerging field of neurobehavioral toxicology and the potential of behavior studies as a noninvasive and economical means for risk assessment and monitoring. Pioneers in this field explore its promise for detecting environmental toxins, protecting us from exposure, and treating those who are exposed.
