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
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
It is often said that the “dosage” of any substance determines its remedy or poison effect. Heavy metal sources encompass sewage, pesticides, fertilizers, environmental contamination, occupational exposure/contact through inhalation, ingestion, and skin. Before the advent of technology/the industrial revolution, communicable diseases ravaged the human race but this seems to have given way to non-communicable diseases such as cancers, renal failure, hormonal distortion enzymes, inhibition of fetal growth, and DNA damage causing negative health issues due to heavy metals. This book brings to the fore probably the most recent experimental research/review on heavy metal contamination, remediating techniques, cellular tissue damage, and toxicological and antioxidant effects of heavy metals. It is hoped that its contents will make interesting reading for all.

Book Description
People are increasingly concerned about potential environmental health hazards and often ask their physicians questions such as: "Is the tap water safe to drink?" "Is it safe to live near power lines?" Unfortunately, physicians often lack the information and training related to environmental health risks needed to answer such questions. This book discusses six competency based learning objectives for all medical school students, discusses the relevance of environmental health to specific courses and clerkships, and demonstrates how to integrate environmental health into the curriculum through published case studies, some of which are included in one of the book's three appendices. Also included is a guide on where to obtain additional information for treatment, referral, and follow-up for diseases with possible environmental and/or occupational origins.

Book Description
Lupus, rheumatic fever, colitis, arthritis, dermatitis, insomnia, depression, hallucinations – what do all these illnesses have in common? They were all experienced by a 12-year-old girl in a case study in an American journal of child psychiatry. The cause? – mercury vapor she inhaled from mercury that had been spilled on the carpet in the room she slept in. After removing the carpet and treatment with chelation drugs, the girl returned to good health. Mercury poisoning can cause a variety of illnesses such as chronic fatigue, fibromyalgia, ADHD, bipolar disorder, sinusitis, tinnitus, balance problems, tremor, insomnia, inflammatory bowel disease, dermatitis, excessive thirst, salivation and a host of other symptoms. Is mercury from dental amalgams affecting your health? Dental associations claim the mercury in fillings is perfectly safe, but the mercury inhaled from “silver” fillings is 15 times more toxic than lead. The World Health Organization report states that people with amalgams have a daily mercury intake of 4 to 21 micrograms of mercury per day. For many people this exceeds the Environmental Protection Agencies limit of just 7 micrograms per day. Yet there are no Government warnings about this exposure. Those who grind their teeth or chew gum will have even higher exposure. If you eat 100 grams (3.5 ounces) of tuna, that adds another 35 micrograms. Even if your mercury blood level is within the so-called “normal” range, if you don't excrete mercury efficiently it can build up in your brain, liver, kidney, thyroid and other organs over years of continuous exposure. The effects of prolonged exposure to mercury can be delayed for years, making it difficult to determine the cause of your illness. Diseases such as chronic fatigue and fibromyalgia affect millions of people around the world. Doctors say the causes of these illnesses are unknown and there is no cure. This book provides cases histories of many diseases which were caused by mercury and subsequently cured using chelation therapy. It also takes you step by step through the process of safely chelating heavy metals from your body.

Book Description
Complex and ever changing in its forms and functions, the element mercury follows a convoluted course through the environment and up the food chain. The process is complicated further by the fact that the difference between tolerable natural background levels and harmful effects in the environment is exceptionally small and still not completely understood. Written by recognized national and international authority on chemical risk assessment, Ronald Eisler, Mercury Hazards to Living Organisms explores the biological, physical, and chemical properties of mercury and its compounds. Rich in facts and information, the book provides a fundamental look at the issues. A synthesis of current scientific reviews, the book documents the significance of mercury concentrations in abiotic materials, plants, invertebrates, amphibians, reptiles, elasmobranch, fishes, and birds, as well as humans and other mammals. The author reviews historical and current uses and sources of mercury along with its physical, chemical, biological, and biochemical properties. He summarizes mercury transport and speciation processes and analytical techniques for mercury measurement. The book includes coverage of lethality to wildlife, domestic animals, and humans; administration routes and their effects; and sublethal effects such as cancers, birth defects, and chromosomal aberrations.
