History Of Risk Assessment In Toxicology

Book Description :

History of Risk Assessment in Toxicology guides the reader through the historical narrative of the evolution of risk assessment thinking in human and environmental practices. Risk assessment concepts are used in many different professional practice areas. In the health and environmental practices of risk assessment, the critical issue is often what chemical concentration in air, water, food, or a solid substance is acceptable, or considered not to result in any adverse effect. The book reviews examples from early scientific and health studies to showcase the foundations of risk assessment. The book also explores the development of risk assessment as practiced by major regulatory bodies such as the US Food and Drug Administration (FDA), the Occupational Safety & Health Administration (OSHA), and the US Environmental Protection Agency (EPA) to reveal how risk assessment has evolved in the 20th and 21st centuries. Modern technology has created opportunities in silicon in vitro, computational modeling, omics, and big data techniques to assess the toxicity of chemicals, while traditional approaches to risk assessment are being challenged with new and innovative approaches. Finally, current issues being debated and tested in risk assessment are outlined with possible future avenues suggested. Presents the first dedicated history on the evolution of risk assessment in toxicology Reviews the development of major US and EU regulatory bodies Provides a context to current debates surrounding the future of risk assessment Reviews examples from early scientific and health studies to showcase the foundations of risk assessment

Book Description :

Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.

The book allows students to concurrently learn concepts in both biomedical and environmental toxicology fields, thus better equipping them for the many career opportunities toxicology provides. This book will also be useful to those wishing to reference how disciplines interact within the broad field of toxicology. Covers major topics and newer areas in toxicology, including nanotoxicology, Tox21, epigenetic toxicology, and organ-specific toxicity Includes a variety of perspectives to give a complete understanding of toxicology Written by specialists within each subject area, e.g., a chemical engineer, to ensure concepts are clearly explained

Book Description :

Molecular Biological Markers for Toxicology and Risk Assessment provides an introduction to the exciting field of biomarkers and their use in toxicology and risk assessment. In recent years, new classes of molecular biomarkers capable of detecting early manifestations of ongoing chemical-induced cell injury and cell death have been developed as a result of advances in analytical chemistry, molecular biology, and computational modeling. The interplay between these emergent tools of science has resulted in new insights into initial mechanisms of chemical-induced toxicity and carcinogenicity. Molecular Biological Markers for Toxicology and Risk Assessment guides the reader through a broad range of molecular biological markers, including the "omic" biomarkers, and provides an examination of the various elements in the evolution of these modern tools. It then explores possible ways in which these markers may be applied to advance the field of chemical risk assessment. Since molecular biomarkers and related technologies are inherently complex, the book concludes with a section on risk communication in order that readers may appreciate both the strengths and limitations of molecular biological marker approaches to risk assessment practice. Introduces the use of molecular biomarkers to detect toxic effects of chemicals as early as possible Provides an accessible overview of this emerging, interdisciplinary field, to best inform decision making in chemical and pharmaceutical safety Includes a section on risk communication of these complex concepts, essential for effective risk assessment Provides new insights into the initial mechanisms of chemical-induced toxicity and carcinogenicity

Book Description :

Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Book Description :

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.

Book Description :

The History of Alternative Test Methods in Toxicology uses a chronological approach to demonstrate how the use of alternative methods has evolved from their conception as adjuncts to traditional animal toxicity tests to replacements for them. This volume in the History of Toxicology and Environmental Health series explores the history of alternative test development, validation, and use, with an emphasis on humanity and good science, in line with the Three Rs (Replacement,Reduction, Refinement) concept expounded by William Russell and Rex Burch in 1959 in their now classic volume, The Principles of Humane Experimental Technique. The book describes the historical development of technologies that have influenced the application of alternatives in toxicology and safety testing. These range from single cell monocultures to sophisticated, miniaturised and microfluidic organism-on-a-chip devices, and also include molecular modelling, chemoinformatics and QSAR analysis, and the use of stem cells, tissue engineering and hollow fibre bioreactors. This has been facilitated by the wider availability of human tissues, advances in tissue culture, analytical and diagnostic methods, increases in computational processing, capabilities, and a greater understanding of cell biology and molecular mechanisms of toxicity. These technological developments have enhanced the range and information content of the toxicity endpoints detected, and therefore the relevance of test systems and data interpretation, while new techniques for non-invasive diagnostic imaging and high resolution detection methods have permitted an increased role for human studies. Several key examples of how these technologies are being harnessed to meet 21st century safety assessment challenges are provided, including their deployment in integrated testing schemes in conjunction with kinetic modelling, and in specialized areas, such as inhalation toxicity studies.

Book Description :

The public depends on competent risk assessment from the federal government and the scientific community to grapple with the threat of pollution. When risk reports turn out to be overblownâ€"or when risks are overlookedâ€"public skepticism abounds. This comprehensive and readable book explores how the U.S. Environmental Protection Agency (EPA) can improve its risk assessment practices, with a focus on implementation of the 1990 Clean Air Act Amendments. With a wealth of detailed information, pertinent examples, and revealing analysis, the volume explores the "default option" and other basic concepts. It offers two views of EPA operations: The first examines how EPA currently assesses exposure to hazardous air pollutants, evaluates the toxicity of a substance, and characterizes the risk to the public. The second, more holistic, view explores how EPA can improve in several critical areas of risk assessment by focusing on cross-cutting themes and incorporating more scientific judgment. This comprehensive volume will be important to the EPA and other agencies, risk managers, environmental advocates, scientists, faculty, students, and concerned individuals.
