The contributors provide a rich overview of the strengths and limitations of using risk assessment methods in the occupational health arena. This book brings together a distinguished group of experts in occupational health and risk assessment who express diverse views on the usefulness of risk assessment in the protection of worker health. Representatives from regulatory agencies, labor, industry, and academia consider both policy and technical issues, providing a rich overview of the strengths and limitations of using risk assessment methods in the occupational health arena. Both policy and technical issues are explored. Several contributors focus on the policy implications of regulatory agencies' increasing reliance on risk assessment to guide occupational and environmental risk reduction strategies. Others consider specific methodological issues relating to the application of state-of-the-art scientific developments to the evaluation of occupational risks. Chapters are organized to consider specific aspects of the field including current applications of risk assessment methods by federal regulatory agencies; approaches to improving the use of epidemiological data in risk assessment; the use of animal bioassay data to predict occupational risks; potential uses of cutting-edge scientific data on toxicological mechanisms, toxicokinetics, and biomarkers in risk assessment; specific issues including ethics, values, and sociopolitical aspects of the process, and a concluding chapter discussing future directions to the evaluation and regulation of risks to worker health and safety. Given the range of policy and technical issues explored, this collection will be invaluable to professionals as well as academics in the fields of occupational health and environmental risk assessment.

Evaluates the risks to human health and the environment posed by lindane, an isomer of hexachlorocyclohexane used, for more than four decades, as a broad-spectrum insecticide. Although most lindane is used in agriculture for the treatment of seeds and soils, other important applications include the protection of wood and timber, the treatment of veterinary ectoparasites, and the treatment of scabies and body lice in humans.

Evaluates the risks to human health and the environment posed by the mining, refining, industrial use, and recycling of platinum and selected platinum compounds. Because of its exceptional catalytic properties, resistance to chemical corrosion, and high mechanical strength, platinum is widely used in the chemical and petroleum industries, most notably in the production of catalysts, including devices for reducing hazardous gas emissions. The growing use of catalytic converters to reduce pollution from automobile exhausts has caused a sharp increase in the world demand for this metal. Compounds such as cisplatin also have important therapeutic applications.

Evaluates the risks to human health and the environment posed by two partially halogenated chlorofluorocarbons: dichlorofluoromethane (HCFC 21) and chlorodifluoromethane (HCFC 22). These two methane derivatives were selected for evaluation because of their potential use as substitutes for those fully halogenated chlorofluorocarbons that are being phased out as a result of the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer. The evaluation is intended to assist industry in its urgent search for acceptable substitute chemicals, most notably for use as refrigerants, as propellants in aerosols, and as blowing agents for the production of polystyrene. While data on human toxicity are thoroughly reviewed, the greatest challenge is to find the most accurate models for predicting levels of release to the environment and estimating the potential of these chemicals to deplete the ozone layer.

This is a comprehensive and up-to-date investigation of a deadly toxin and its impact on ecology and human health.

Part 2 deals with the latest findings from a wide range of international research groups into the repercussions of arsenic exposures on human health and the ecosystem.

Names like Love Canal, Chernobyl, and the Exxon Valdez have come to symbolize our anxiety over toxic substances in the environment and their effects on human health and the ecology. Yet, as toxins continue to accumulate rapidly in our air, water, and soil, major environmental disasters are only the most obvious manifestation of a complex and growing problem - the tip of the iceberg, so to speak. The need for scientists and nonscientists who are well versed in the fundamentals of environmental toxicology has never been greater, so too, the need for introductory texts in the field. Based on a groundbreaking course given at the University of Illinois for the past two decades, Toxic Substances in the Environment is a superb introduction to the field of environmental toxicology. While the majority of texts and references on toxins in the environment suffer from either a dearth of careful examination or an overabundance of ponderous detail, this book offers just the right balance of accessibility and scientific rigor. It is basic enough to serve as an advanced undergraduate introduction to environmental toxicology and its two most prominent subgroups - the ecological impact of pollutants, and the effect of pollutants on human health. Yet, at the same time, it is unstinting in scientific detail. While the range of topics is broad, this book offers concise and engaging discussions of diverse subjects such as air pollution and global ecosystems; neurotoxicity; genetic toxicology; social issues associated with environmental toxins; and many others. Supported by more than 100 tables and illustrations, the text is organized around a series of case studies that illustrate the hazards associated withparticular substances and demonstrate the multidisciplinary approach that is essential to any effective effort to clean up or prevent contamination. This case study orientation, along with an annotated bibliography and a unique chapter on policy and policy issues, in which the author offers a rundown of the major public and civic environment action groups, makes Toxic Substances in the Environment a useful professional reference. Reflecting a number of the major concerns and interests voiced by students majoring in a variety of disciplines, including biology, chemistry, agriculture, economics, and engineering, this superb didactic tool is destined to become the environmental toxicological bible of future generations.

The author has extracted a selection of the most fundamental and generally useful material from the vast literature on free radicals. Electron spin resonance, radical pairs, CIDNP and CIDEP, alkyl radicals and applications in synthesis are among the topics covered.

The proliferation of chemical substances in commerce poses significant scientific and philosophical problems. The scientific challenge is to develop data, methodologies and techniques for identifying and assessing toxic substances before they cause harm to human beings or the environment. The philosophical problem is to determine how much scientific information we should demand for this task consistent with the pursuit of other social goals. In this book, Carl Cranor utilizes material from ethics, philosophy of law, epidemiology, tort law, regulatory law, and risk assessment to argue that the evidentiary standards for science used in the law to control toxics ought to be evaluated with the purposes of the law in mind. Demanding too much for this purpose will slow the evaluation and lead to an excess of toxic substances left unidentified and unassessed, thus leaving the public at risk. Demanding too little may impose other costs. Analyzing this tension philosophically, Cranor argues for an appropriate balance between these social concerns. Although the use of somewhat less stringent evidentiary standards for expert testimony in tort law cases and the use of expedited procedures in the regulatory field might in some cases lead to mistakes of overcompensation or overregulation, the overall social costs would be less than the alternatives. Justice requires that we tolerate the chance of such errors and that we resist the temptation to demand the most science intensive evaluation of each substance in order to protect individuals better from mistakes of undercompensation and underregulation. The role of science in the control of toxic substances is an important public philosophical issue, yetuntil now has received little discussion by philosophers. Regulating Toxic Substances addresses this subject in a way that speaks both to a well-informed public and to experts in several disciplines, including philosophy, risk assessment, environmental and tort law, environmental studies, and public health policy.

Human exposure to toxic substances that cause cancer, reproductive abnormalities, and other adverse health effects is a topic of increasing interest to scientists, journalists, workers, business executives, advocacy groups, and the public at large. Citizen concern has prompted the government to establish an elaborate regulatory system designed to protect people from chemical exposures. Harnessing Science examines the role of science in toxic chemical regulation at the U.S. Environmental Protection Agency. The book postulates that scientific knowledge and advice from experts outside of government is critical to the competence and credibility of regulations designed to protect public health.

This unique volume takes a close look at the contributions of three specific organizations that were designed to improve regulatory science: the Chemical Industry Institute of Toxicology (CIIT), the Science Advisory Board of the EPA, and the Health Effects Institute. Early chapters trace the origins and histories of each of these three organizations. Then regulatory case studies of selected chemical substances (unleaded gasoline, perchloroethylene, formaldehyde, nitrates, and carbon monoxide) are used to assess the contributions of CIIT, SAB, and HEI. The final chapter makes specific recommendations designed to strengthen these organizations. Harnessing Science for Environmental Regulation is essential reading for anyone who is interested in how science influences regulatory decisions about human exposure to toxic chemicals. It will be of special interest to federal and state policy makers, practicing scientists, environmental advocates, risk assessors, corporate managers, and environmental journalists.

Chromium and its compounds are widely used by modern industries resulting in large quantities of this element being discharged into the environment and there is now a growing concern about the effects of chromium in the environment. This volume provides a comprehensive assessment of the uses of chromium, its sources and occurrence in the air, water and soils. It gives a detailed and expert description of chromium chemistry, analytical chemistry, biochemistry and known health effects. It also contains a comprehensive compendium of epidemiological data listed according to exposure type along with models of toxicity. Most of the known environmental and health effects of chromium are treated here along with a discussion of dose-response relationships. A key aspect of the book and one of its most useful features is that it serves as a guide to the analytical procedures and their limitations that are suitable for use in environmental and biological monitoring.

Continuing a long tradition, Lu's Basic Toxicology, Seventh Edition, combines relatively comprehensive coverage of toxic substances in food, air, and water with brevity, thereby continuing to serve as an updated introductory text for toxicology students and for those involved in allied sciences that require a background in toxicology. The new edition, which now becomes an edited work with contributions from experts around the globe, features four new chapters and a number of existing chapters that have been updated and expanded, notably those on mechanisms of toxic effects, conventional toxicity studies, the cardiovascular system, and risk assessment and regulatory toxicology. The book consists of four parts (Part I-Part IV) that provide guidance on principles of toxicology and testing procedures for toxicities as well as a concise, yet detailed, mechanism of both target organ and nontarget organ toxicities. The book is rounded off with a final section (Part IV) on the toxic effects of chemicals and risk assessment, giving toxicologists, both students and practicing professionals, the necessary tools to enhance their practice. This edition includes new chapters on Clinical Toxicology, Systems Toxicology, Chemicals and Children, and Toxicology of Reproductive Systems, providing the essentials of these topics in the same style as the other chapters in the book. With separate subject and chemical indexes, this is a useful, quick shelf reference for everyone working in toxicology today.

Traditional toxicology textbooks tend to be doorstops: tomes filled with important but seemingly abstract chemistry and biology. Meanwhile, magazine and journal articles introduce students to timely topics such as EPA and endocrine disruption or the carcinogenic effects of pesticides, but don't provide the fundamentals needed to understand the science of toxicity. Written by a professor of toxicology, Modern Poisons bridges this gap. This accessible book explains basic principles in plain language while illuminating the most important issues in contemporary toxicology. Kolok begins by exploring age-old precepts of the field such as the dose-response relationship and the concept, first introduced by Ambroise Pare in the sixteenth century, that a chemical's particular action depends on its inherent chemical nature. The author goes on to show exactly how chemicals enter the body and elicit their toxic effect, as well as the body's methods of defence. With the fundamentals established, Kolok digs into advances in toxicology, tracing the field's development from World War II to the present clay. The book examines both technical discoveries and their impacts on public policy. Highlights include studies of endocrine-disrupting chemicals in toiletries and prescriptions, the emerging science on prions, and our growing understanding of epigenetics. Readers learn not only how toxic exposure affects people and wildlife, but about the long-term social and environmental consequences of our chemicals. Whether studying toxicology itself, public health, or environmental science, readers will develop a core understanding of, and curiosity about, this fast-changing field.

This glossary expands upon the Comprehensive Glossary of Terms Used in Toxicology. Like its predecessor, it addresses the need for harmonized toxicology terminology, and has undergone a full, comprehensive and rigorous review by IUPAC Committees. It serves as the reference glossary for students and researchers studying the chemical and molecular biological bases of toxicology, and for those involved in chemicals legislation, regulation and risk assessment. Toxicology uses terminology from many disciplines that have been revolutionized by recent developments in molecular biology and biochemistry, and this glossary provides a compilation of definitions of molecular entities that impact on toxicology. Extensive Notes are included to provide context for many of the proteins and important genes defined, with disambiguation where entities are referred to by different names in the literature. We hope that this will be helpful to students and professionals alike.

The potential impact of anthropogenic pollutants such as agrochemicals on the environment is of global concern. Increasing use of certain compounds can result in contamination of food, water and atmospheric systems and in order to combat this pollution it is important to be able to accurately monitor the short and long term effects. This book describes the latest non-traditional terrestrial species models used as indicators of the toxic effects of environmental pollutants. The book enables understanding of the effects of pollutants in non-target species, and therefore enables analysis of the effects on ecosystems. This book will be of interest to anyone interested in developing new biomarker species with high degrees of ecological relevance. It will serve as a useful resource for regulatory and research toxicologists, particularly those interested in soil screening and the effects of pollutants on wildlife and insects and their use as biological indicators.

The tools for detecting false positives, false negatives, and interference in interactions when testing and monitoring therapeutic drug use For physicians monitoring a patient's progress, efficacy of treatment is often linked to a patient's response to medication. Determining whether a patient is taking the prescribed amount, the drug or dosage is effective, or the prescribed medication is interacting with other drugs can be determined through drug testing. Written as a guide for toxicologists, chemists, and health professionals involved in patient care, Resolving Erroneous Reports in Toxicology and Therapeutic Drug Monitoring provides an up-to-date introduction to the tests and methodologies used in a toxicology lab as well as the sources of testing error that can lead to false positives, false negatives, and unreliable conclusions of drug abuse or under use. Covering a host of common therapeutic drugs as well as specific types of interference in immunoassays used in drug testing, the book details a number of possible testing scenarios and problems as well as solutions: * False positive results in immunoassays for drugs in abuse testing * Interferences in immunoassays used for monitoring anticonvulsants, tricyclic antidepressants, and digoxin * False positive alcohol tests using breath analyzers and automated analyzers * When a toxicology report is negative in a suspected overdose patient: the world of designer drugs * Effects of drug-herb interactions on therapeutic drug monitoring * Pharmacogenomics and the general principles of genetic analysis * Approaches for eliminating interference/discordant specimen in therapeutic drug monitoring and drugs in abuse testing * What to do in case there is no readily available method for testing Complete with easy-to-read tables and flowcharts, this book helps toxicologists, clinical chemists, clinical pathologists, and forensic pathologists develop accurate, unbiased drug monitoring and toxicology reports. Health care professionals involved in patient care, especially of critically ill patients, will find this guide indispensable in making sure lab tests are reliable enough to provide high-quality care. An indispensable handbook to the entire suite of toxicology lab tests, as well as all the possible sources of testing error, Resolving Erroneous Reports in Toxicology and Therapeutic Drug Monitoring offers clear remedies for eliminating and preventing testing error.

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.

Contaminants of emerging concern in the marine environment: current challenges in marine pollution reviews the available data in relation to contaminants of emerging concern (CECs) in the marine environment: main sources, transport pathways, distribution in seawater and sediments, bioaccumulation, and biological effects. Each chapter recaps the most relevant information about the main groups of CECs, describing the particularities and specificities of each group and focusing on the most relevant individual contaminants. CECs are not regulated substances, and therefore not considered in national and international monitoring programs, even though they may have a potential impact on the environment due to their continuous input, relative persistence, and/or toxicity. CECs are relevant not only in continental and coastal areas close to their main sources, but also in the open sea, because some of them are likely to be transported long distances through air deposition or absorbed into particulate material. The persistence of many degradable substances in the marine environment increases when they are absorbed into particulate material/sediments and/or when they are subjected to anaerobic conditions that slow down the degradation kinetic of many contaminants. Bioaccumulation of several CECs has been confirmed in different coastal organisms; however, in general, the information available (species and trophic levels considered) is very limited because most studies are mainly focused on specific coastal areas. This book offers useful information about not regulated contaminants that are not considered in international monitoring programs but have potential impacts in coastal and open-sea areas. Therefore reading the book will allow them to improve their view about the real impact of current-use contaminants in the marine environment.

Environmental pollution as a consequence of diverse human activities has become a global concern. Urbanization, mining, industrial revolution, burning of fossil fuels/firewood and poor agricultural practices, in addition to improper dumping of waste products, are largely responsible for the undesirable change in the environment composition. Environmental pollution is mainly classified as air pollution, water pollution, land pollution, noise pollution, thermal pollution, light pollution, and plastic pollution. Nowadays, it has been realized that with the increasing environmental pollution, impurities may accumulate in plants, which are required for basic human uses such as for food, clothing, medicine, and so on. Environmental pollution has tremendous impacts on phenological events, structural patterns, physiological phenomena, biochemical status, and the cellular and molecular features of plants. Exposure to environmental pollution induces acute or chronic injury depending on the pollutant concentration, exposure duration, season and plant species. Moreover, the global rise of greenhouse gases such as carbon monoxide, carbon dioxide, nitrous oxides, methane, chlorofluorocarbons and ozone in the atmosphere is among the major threats to the biodiversity. They have also shown visible impacts on life cycles and distribution of various plant species. Anthropogenic activities, including the fossil-fuel combustion in particular, are responsible for steady increases in the atmospheric greenhouse gases concentrations. This phenomenon accelerates the global heating. Studies have suggested that the changes in carbon dioxide concentrations, rainfall and temperature have greatly influenced the plant physiological and metabolic activities including the formation of biologically active ingredients. Taken together, plants interact with pollutants, and cause adverse ecological and economic outcomes. Therefore, plant response to pollutants requires more investigation in terms of damage detection, adaptation, tolerance, and the physiological and molecular responses. The complex interplay among other emerging pollutants, namely, radioisotopes, cell-phone radiation, nanoparticles, nanocomposites, heavy metals etc. and their impact on plant adaptation strategies, and possibility to recover, mitigation, phytoremediation, etc., also needs to be explored. Further, it is necessary to elucidate better the process of the pollutant's uptake by plant and accumulation in the food chain, and the plant resistance capability against the various kinds of environmental pollutants. In this context, the identification of tolerance mechanisms in plants against pollutants can help in developing eco-friendly technologies, which requires molecular approaches to increase plant tolerance to pollutants, such as plant transformation and genetic modifications. Pollutant-induced overproduction of reactive oxygen species that cause DNA damage and apoptosis-related alterations, has also been examined. They also trigger changes at the levels of transcriptome, proteome, and metabolome, which has been discussed in this book.
