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 excerpt: Food toxicology studies how natural or synthetic poisons and toxicants in diverse food products cause harmful, detrimental, or adverse side effects in living organisms. Food toxicology is an important consideration as food supply chain is becoming more multinational in origin, and any contamination or toxic manifestation may cause serious, wide-spread adverse health effects. Food Toxicology covers various aspects of food safety and toxicology, including the study of the nature, properties, effects, and detection of toxic substances in food and their disease manifestations in humans. It will also include other aspects of consumer product safety. The first two chapters discuss the measurement of toxicants and toxicity and the importance of dose-response in food toxicology. Additional chapters discuss the aspects of food associated carcinogenesis and food-derived chemical carcinogenesis, food allergy, pathogens associated with fruits and vegetables, and the detrimental effects of radionuclides exposure. The chapters also cover the most important heavy metal contaminants, namely mercury, lead and vanadium, and Fluoride toxicity, which is extensively discussed in its own chapter. Toxicologists, scientists, researchers in food toxicology, nutritionists, and public health care professionals will find valuable information in this book on all possible intricate areas of food toxicology.

This book was released on 2015-06-17 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

Book excerpt: 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 excerpt: One morning in 2000, Dr. Jane Hightower walked into her exam room to find a patient with disturbing symptoms she couldn’t explain. The woman was nauseated, tired, and had difficulty concentrating, but a litany of tests revealed no apparent cause. She was not alone. Dr. Hightower saw numerous patients with similar, inexplicable ailments, and eventually learned that there were many more around the nation and the world. They had little in common—except a healthy appetite for certain fish. Dr. Hightower’s quest for answers led her to mercury, a poison that has been plaguing victims for centuries and is now showing up in seafood. But this “explanation” opened a Pandora’s Box of thornier questions. Why did some fish from supermarkets and restaurants contain such high levels of a powerful poison? Why did the FDA base its recommendations for “safe” mercury consumption on data supplied by Saddam Hussein’s Ba’athist extremists? And why wasn’t the government warning its citizens? In Diagnosis: Mercury, Dr. Hightower retraces her investigation into the modern prevalence of mercury poisoning, revealing how political calculations, dubious studies, and industry lobbyists endanger our health. While mercury is a naturally occurring element, she learns there’s much that is unnatural about this poison’s prevalence in our seafood. Mercury is pumped into the air by coal-fired power plants and settles in our rivers and oceans, and has been dumped into our waterways by industry. It accumulates in the fish we eat, and ultimately in our own bodies. Yet government agencies and lawmakers have been slow to regulate pollution or even alert consumers. Why? The trail of evidence leads to Canada, Japan, Iraq, and various U.S. institutions, and as Dr. Hightower puts the pieces together, she discovers questionable connections between ostensibly objective researchers and industries that fear regulation and bad press. Her tenacious inquiry sheds light on a system in which, too often, money trumps good science and responsible government. Exposing a threat that few recognize but that touches many, Diagnosis: Mercury should be required reading for everyone who cares about their health.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Each year, Americans consume hundreds of food products that contain truly dangerous compounds, including heavy metals, pesticides, and other harmful additives—with the blessing of the FDA. Why is this happening and why haven’t you heard about it? In Unsafe at Any Meal, Dr. Renee Dufault, former food investigator for the Food and Drug Administration, provides the startling answers. While at the FDA, Dr. Dufault discovered that mercury—a highly toxic metal—was contaminating the plumbing systems of many food manufacturing plants. Upon further examination, she discovered that the same mercury was also evident in a number of processed foods commonly sold in supermarkets. When Dr. Dufault revealed these disturbing findings to her superiors, she was told to stop her investigation. Her continued efforts to raise the issue always met with a dead end, so she chose to take an early retirement from the FDA. Dr. Dufault then devoted her energy to making the public aware of the insidious dangers that contaminate our food. In 2010, she founded an organization of scientists to study the scope of this problem and has published numerous research articles on the topic with little fanfare. To expose what still seems to be a well-kept secret by the FDA, she has written Unsafe at Any Meal to provide consumers with the information they need to know. The book begins with the author’s story leading up to the creation of this work. It then describes the various toxic substances that are most commonly found in our food supply, and explains how they affect your genes, health, and the surrounding environment. After examining the Standard American Diet, which is sorely lacking in disease-preventing nutrients, it discusses the country’s trend toward consuming a skyrocketing amount of ingredients that can contain heavy metals. It further shows how exposure to these heavy metals can contribute to conditions such as ADHD or autism. Also included is a helpful guide to reading food labels, recognizing misleading marketing tactics, and knowing what to look for—and what to look out for—in the aisles of your grocery store. Over fifty years ago, Rachel Carson’s book Silent Spring exposed the dangers of DDT in our food supply. Unfortunately, it seems that the problem of food contamination has actually become worse. Backed by research and first-hand experience, Dr. Dufault reveals how the FDA has failed us, and outlines how you can protect yourself and your family by knowing what to avoid and by filling your kitchen with food that is clear of toxins.

Available in PDF, EPUB and Kindle. Book excerpt: Mercury pollution and contamination are widespread, well documented, and continue to pose a public health concern in both developed and developing countries. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly to include the fields of biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists begun to establish a holistic approach to studying mercury pollution that integrates chemistry, biology, and human health sciences. Mercury in the Environment follows the process of mercury cycling through the atmosphere, through terrestrial and aquatic food webs, and through human populations to develop a comprehensive perspective on this important environmental problem. This timely reference also provides recommendations on mercury remediation, risk communication, education, and monitoring.

Book excerpt: 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.
