Not a day goes by that humans aren't exposed to toxins in our environment - be it at home, in the car, or workplace. But what about those toxic places and items that aren't marked? Why are we warned about some toxic spaces' substances and not others? The essays in Inevitably Toxic consider the exposure of bodies in the United States, Canada and Japan to radiation, industrial waste, and pesticides. Research shows that appeals to uncertainty have led to social inaction even when evidence, e.g. the link between carbon emissions and global warming, stares us in the face. In some cases, influential scientists, engineers and doctors have deliberately "manufactured doubt" and uncertainty but as the essays in this collection show, there is often no deliberate deception. We tend to think that if we can't see contamination and experts deem it safe, then we are okay. Yet, having knowledge about the uncertainty behind expert claims can awaken us from a false sense of security and alert us to decisions and practices that may in fact cause harm.

The most talked about metalloid in the modern world, arsenic affects the liver, kidney, and lungs; leads to cardiovascular diseases, cancer, and diabetes; and may cause blindness with long-time exposure. With naturally occurring arsenic boosted by mining and other industrial processes contaminating soil and drinking water, arsenic toxicity is a major challenge to health professionals and scientists around the world. Arsenic Toxicity: Prevention and Treatment reviews current understanding of arsenic poisoning and the health consequences resulting from exposure. The book paints a vivid picture of the sources of arsenic toxicity including ground water; food such as rice, fruits and vegetables, fish, and chicken as well as occupational exposures from industries using inorganic arsenic such as glass production, non-ferrous alloy, wood preservation, and semiconductor manufacturing units. The text details the health hazards of arsenic toxicity and then examines removal, mainly from soil and water, highlighting eco-friendly bioremediation techniques. It discusses classical and modern treatment methods for arsenic toxicity, emphasizing the use of nutraceuticals and functional foods. With its focus on the remediation of arsenic toxicity using nutraceutical and functional food, the book provides a unique resource for combatting this global scourge. It provides strategies for defending arsenic toxicity naturally without causing any additional adverse effects.

Environmental issues such as ozone layer depletion, overpopulation, biodiversity loss, global warming, natural resource depletion, and so on affect every organism on the planet somehow. Environmental biotechnology applications can help to protect and restore the quality of the environment. The goal is to use biotechnology with other technologies and safety procedures to prevent, arrest, and reverse environmental degradation. Environmental biotechnology is one of the most rapidly expanding and practically useful scientific fields. Biochemistry, physiology and genetic research of microorganisms can be converted into commercially available technologies for reversing and preventing further deterioration of the earth's environment. Solid, liquid, and gaseous wastes can be altered either by recycling new by-products or by purifying to make the end product less harmful to the environment. Biotechnology for Toxic Remediation and Environmental Sustainability discusses the removal of pollutants by absorption techniques and recycling wastewater into valuable by-products and biofuels by microorganisms. Moreover, this book also addresses corrosion prevention by green inhibitors, uses electrochemical systems for renewable energy and waste recycling using microbes, and recent food safety and security trends in the food microbiome. On the other hand, this book also discusses therapy and treatments against antibiotic-resistant bacteria, anti-cancer and pharmacological properties of thymoquinone and preventive properties of zinc nanoparticles against stress-mediated apoptosis in epithelial cells. Features Covers all aspects of Biotechnological application in the environment Discusses sustainable technology for the wastewater treatment and value-added products from wastewater Focuses on research activities Green corrosion inhibitors, bio-electrochemical systems, food safety and security, and antimicrobial resistance The book is a valuable resource for the undergrad and graduate students, doctoral and post-doctoral scholars, industrial personnel, academicians, scientists, researchers, and policymakers involved in understanding and implementing applications of biotechnology for environmental toxic remediation.

We are all just a little bit plastic. Traces of bisphenol A or BPA, a chemical used in plastics production, are widely detected in our bodies and environment. Is this chemical, and its presence in the human body, safe? What is meant by safety? Who defines it, and according to what information? "Is It Safe?" narrates how the meaning of the safety of industrial chemicals has been historically produced by breakthroughs in environmental health research, which in turn trigger contests among trade associations, lawyers, politicians, and citizen activists to set new regulatory standards. Drawing on archival research and extensive interviews, author Sarah Vogel explores the roots of the contemporary debate over the safety of BPA, and the concerns presented by its estrogen-like effects even at low doses. Ultimately, she contends that science alone cannot resolve the political and economic conflicts at play in the definition of safety. To strike a sustainable balance between the interests of commerce and public health requires recognition that powerful interests will always try to shape the criteria for defining safety, and that the agenda for environmental health research should be protected from capture by any single interest group.

Botulinism toxins are widely used for the treatment of medical and aesthetic disorders. They are considered the gold standard for the treatment of muscular spasticity and facial dynamics wrinkles. The authors' of this book discuss botulinum toxin resistance in medical and aesthetic arenas; recommendations of dilutions for treatment applications (general recommendations were to inject the toxin diluted, because highly concentrated toxins were believed to be more toxic and dangerous); a novel methodology of transdermal delivery of botulinum toxin with the aid of a dermic pen for hyperhidrosis; emerging treatment options for lower urinary tract symptoms that involve a bladder neck injection of a botulinum toxin; and a discussion on the cases of botulism that arise from consuming certain foods particularly in the Arctic regions.

Based on the findings of the 1997 report, provides information on the feasibility of an exposure reconstruction model for wartime herbicide exposures of US veterans of Vietnam. Recommendations are made for the Dept. of Veterans Affairs and other government agencies to facilitate additional epidemiologic studies of veterans. Links to the NAP home page and other related sites are provided.

The end of the 20th century brought with it a revolution in molecular biology that culminated in advances such as the completion of the human genome. This has brought optimism to the fields of toxicology and environmental health, and the anticipation that molecular biomarkers might soon come of age and have a major impact on human and environmental health. Biomarker research is an area of current interest to scientists in a number of fields that are concerned with environmental exposure to pollutants and environmentally associated disease.

Biomarkers of Environmentally Associated Disease: Technologies, Concepts, and Perspectives provides comprehensive coverage of the current status and future prospects of a field that will play a key role in emerging areas of public health and medicine. It focuses on the risk to human and environmental health of exposure to persistent organic pollutants, heavy metals, airborne toxics, environmental estrogens, and other environmental pollutants. This material will aid researchers in understanding, treating, and preventing environmentally induced disease.

Validated molecular biomarkers have long been recognized as invaluable tools for identifying and preventing human disease. As biomarkers begin to be applied more widely, it is also important to assure that they are implemented ethically, with attention to the social and legal issues associated with their use. Biomarkers of Environmentally Associated Disease is an outstanding resource providing state-of-the-art information for the fields that encompass molecular biomarkers.

In response to the concerns voiced by Vietnam veterans and their families, Congress called upon the National Academy of Sciences (NAS) to review the scientific evidence on the possible health effects of exposure to Agent Orange and other herbicides. This call resulted in the creation of the first NAS Institute of Medicine Committee to Review the Health Effects in Vietnam Veterans of Exposure to Herbicides in 1992. The committee published its initial findings in the 1994 report Veterans and Agent Orange: Health Effects of Herbicides Used in Vietnam. This report is the result of a 1999 request from the Department of Veterans Affairs (DVA) under the aegis of the Veterans and Agent Orange research program. Specifically, DVA asked the committee to examine evidence regarding the association, if any, between Type 2 diabetes and exposure to dioxin and other chemical compounds in herbicides used in Vietnam. Veterans and Agent Orange: Herbicide/Dioxin Exposure and Type 2 Diabetes reviews the scientific evidence regarding the association, if any, between Type 2 diabetes1 and exposure to dioxin2 and other chemical compounds in herbicides used in Vietnam. This report examines, to the extent that available data permitted meaningful determinations, (1) whether a statistical association with herbicide exposure exists, taking into account the strength of the scientific evidence and the appropriateness of the statistical and epidemiologic methods used to detect the association; (2) the increased risk of the disease among those exposed to herbicides during Vietnam service; and (3) whether there is a plausible biological mechanism or other evidence of a causal relationship between herbicide exposure and the disease.

Consumer and environmental protection depend on the careful regulation of all classes of chemicals. Toxicology is the key science used to evaluate safety and so underpins regulatory decisions on chemicals. With the growing body of EU legislation involved in chemical regulation, there is a concomitant need to understand the toxicological principles underlying safety assessments Regulatory Toxicology in the European Union is the first book to cover regulatory toxicology specifically in Europe. It addresses the need for a wider understanding of the principles of regulatory toxicology and their application and presents the relationship between toxicology and legislative processes in regulating chemical commodities across Europe. This title has a broad scope, covering historical and current chemical regulation in Europe, the role of European agencies and institutions, and also the use of toxicology data for important classes of chemicals, including human and veterinary medicines, animal feed and food additives, biocides, pesticides and nanomaterials. This book is therefore extremely pertinent and timely in the toxicology field at present. This book is an essential reference for regulatory authorities, industrialists, academics, undergraduates and postgraduates working within safety and hazards, toxicology, the biological sciences, and the medicinal and pharmaceutical sciences across the European Union.

Exposure to certain types of mycotoxins, the bioactive secondary metabolites of filamentous fungi, significantly impact the animal industry as well as human health. The contamination of food with mycotoxins is a worldwide problem in animal production and direct consequences are the reducing of food intake and production. In this book, the authors increase the public awareness of the implications of certain types of mycotoxins exposure to promote the health of livestock as well as the general public; an analysis of trichothecens (TCEs), a large group of mycotoxins, and their impact on lifestock health and production are also examined, as well as the occurrence of mycotoxins in animal products such as goat milk. Different strategies implemented for the analysis of a wide spectrum of mycotoxins, as well as their advantages and disadvantages are provided by the authors. In the next few chapters, the occurrence of mycotoxins in cereals and cereal products and in particular, their toxic properties are looked at; a discussion on deoxynivalenol (DON) and related 8-ketotrichothecene mycotoxins, which are extensively distributed in cereal-based foods and feed stuffs worldwide are reviewed; potential toxigenic fungi from diverse habitats are identified with special emphasis on the methods as well as on the genetic markers employed; the importance of performing exposure assessments to Aflatoxin B and some of the most important aspects to consider in the risk assessment process, including the simultaneous presence of other mycotoxins and the challenge of choosing the most suitable method to perform exposure assessment are analyzed; and finally, a review of the occurrence of dietary mycotoxins in Africa as well as the advances in analytical methods of mycotoxin extraction and detection over the last decade is provided.

Drug metabolism, pharmacokinetics and toxicokinetics as determinants of drug attrition and the safety of xenobiotics are critically important. This book presents a comprehensive treatise on the current issues and challenges facing drug metabolism and pharmacokinetics. Readers will find a thorough exploration of their predictive role in impacting drug discovery and development and in improving the success rate and safety assessment of pharmaceuticals and industrial or occupational chemicals. Chapters not only focus on the current state of art, with distinct examples, but on future needs and approaches likely to improve our prediction of potential human risk. Discussions of critical properties that are determinants of a compound's metabolic and pharmacokinetic fate follow introductory chapters. The Drug Discovery process increasingly incorporates pharmacokinetics and drug metabolism screening and focus has shifted towards in silico, computational and systems biology approaches. Core chapters reflect this and the recent interest and need to assess the role of transporters, along with drug metabolizing enzymes, as potential determinants of pharmacokinetic behaviour, toxicity and drug-drug interactions. Lastly, chapters cover the issues and factors involved in translating pharmacokinetics from in silico to in vivo and from animal models to man, and postulate future directions and opportunities. Leading experts from academia, industry and regulatory bodies across the globe contribute their knowledge to this book, which scientists involved in many aspects of the drug discovery process, as well as regulators and postgraduate students, will find a useful resource.

Today, we are surrounded by a multitude of different chemicals that are essential components of our everyday life. As a consequence, there are various hazardous substances like dioxins, phthalates and flame-retardants circulating in the environment. These have an impact on ecosystems, wildlife and possibly human health. In recent years, the phenomenon called endocrine disruption has raised considerable concern. This book discusses the scientific basis of this issue using epidemiological and experimental in vitro and in vivo data about chemicals targeting the hormonal systems. It also provides an up-to-date review of international initiatives (including high-throughput screening, use of model organisms and in silico applications) aiming to screen, detect and functionally test these chemicals. The authors are highly experienced academics and acknowledged experts with both multidisciplinary and international expertise. The book provides an up-to-date, in-depth review of the current field of food safety research describing many of the "hot topics" currently debated. Recent media attention concerning, for example, dioxins in meat and bisphenol A in baby bottles has created a growing interest in food safety-related issues from both consumers and authorities. In addition, European legislation REACH, which requires industry to extensively test chemicals, has led to new initiatives within this area. This book presents a comprehensive overview of the recent international initiatives formed to meet the challenges of environmental pollutants in our food.

In this book, the authors summarise basic and experimental knowledge on sources and toxicity of cadmium and overview mechanisms of toxicity and detoxification for various trophic aquatic organisms exposed to cadmium different routes, which will assist ecological risk assessments involving cadmium toxicity. Cadmium is known to be both extremely toxic and ubiquitous in natural environments. It exists most commonly as a trace constituent in natural ecosystems, where its natural occurrence appears to not cause harm to the environment. However, it can be mobilised by a number of processes especially human activities. Anthropogenic sources of cadmium have contributed large amounts of this potentially toxic metal to the water cycle with ultimate impacts on aquatic ecosystems.

Neurotoxicity syndromes are neurologic disorders caused by exposure to toxic substances through ingestion, injection, cutaneous application, or other method. This includes conditions caused by biologic, chemical, and pharmaceutical agents. This book presents the latest new research in this dynamic field.

Rabies, one of humanity's most ancient and feared diseases, has spread rapidly among the canines of South Texas and in raccoons on the eastern seaboard. The United States, with the world's most complex rabies problems, has seemed helpless in the face of this dangerous outbreak, the worst in decades.

In Mad Dogs: The New Rabies Plague, Don Finley chronicles the epidemic, the politics of response to it, and the most ambitious American attempt yet to erect a barrier against the disease -- in Texas. He tells the stories of those who have been plagued by rabies, and those who have accepted the charge to end the plague.

In South Texas, normally timid coyotes have become fearless, challenging ranch dogs twice their size, attacking an infant on her porch swing, and menacing oil field workers. More ominously, they have infected hundreds of pet dogs, resulting in the exposure of some fifteen hundred people in South Texas to the dreaded disease. Three people, including a fourteen-year-old boy, have died, and the leading edge of the plague line is approaching San Antonio, one of the nation's ten largest cities.

Despite the fact that European nations and Canada have nearly eliminated rabies among wild animals, the virus has been able to spread in the United States because the federal government is unique in its stance that rabies is a local health problem. Controversy over who will pay for a federally approved vaccine is ongoing, even as the virus crosses state and national lines.

The struggle to develop an effective oral rabies vaccination program in the United States began three decades ago. Finley describes the professional feuds, often between scientists and public health officials, thathindered the efforts. In 1995, the USDA granted permission to drop an experimental, genetically engineered vaccine over nearly fifteen thousand square miles of South Texas brushlands in an effort to stop the spread of the disease.

Finley's straightforward language, free of either jargon or hysteria, is a welcome approach in describing the disease's destructive effects. His rare inside look into the politics and the science of disease control within public bureaucracies will engross those interested in science and public health issues, pet owners and wildlife enthusiasts, and those fascinated by infectious disease threats.
