Each day we are exposed to a myriad of natural and human-made chemicals in our food, drinking water, air, soil, at home or at the workplace—pesticide residues, food additives, drugs, household products—but how can we gauge the human health risk posed by these chemicals? Should we believe the somber headlines that depict a serious threat for humans and the environment, or should we follow the reassuring voices of others who claim that the angst is totally unfounded? Why the Dose Matters: Assessing the Health Risk of Exposure to Toxicants uses a rational, science-based approach to explain in plain language that a quantitative view is key for understanding and predicting potentially toxic effects of chemicals. Key Features: Explains the basics of toxicology in easily understandable terms. Includes numerous examples. Clears up common misconceptions and dispels myths. Provides take-home messages for each chapter. This book is aimed at interested laypeople. It uses numerous examples to illustrate the basic concepts and ensure that the reader will get a better understanding of why not only the hazard but also the overall exposure will determine whether some chemicals pose a serious risk while others are of little or negligible concern.

Assessing the Human Health Risks of Trichloroethylene by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Committee on Human Health Risks of Trichloroethylene Pdf
Trichloroethylene is a chlorinated solvent widely used as a degreasing agent in industrial and manufacturing settings. It is also used as a chemical intermediate in making other chemicals and is a component of products such as typewriter correction fluid, paint removers, adhesives, and spot removers. In 2001, EPA issued a draft health risk assessment and proposed exposure standards for trichloroethylene. PA's Scientific Advisory Board (SAB) reviewed the draft and it was issued for public comment. A number of scientific issues were raised during the course of these reviews. Assessing the Human Health Risks of Trichloroethylene identifies and assesses the key scientific issues relevant to analyzing the human health risks of trichloroethylene, considering pertinent toxicologic, epidemiologic, population susceptibility, and other available information, including relevant published scientific literature, EPA's 2001 draft health risk assessment of trichloroethylene, scientific and technical comments received by EPA from public and private sources, and additional relevant information to be provided by the sponsoring agencies. This report highlights issues critical to the development of an objective, realistic, and scientifically balanced trichloroethylene health risk assessment. Guidance for hazard characterization of trichloroethylene is presented in Chapters 2 through 10. Chapter 2 provides guidance for evaluating large sets of epidemiologic data. In Chapter 3, the committee applies this guidance as an example in its evaluation of the epidemiologic data on trichloroethylene and kidney cancer, and this example should help guide evaluations of other cancer risks. Chapter 3 also assesses new information on the kidney toxicity of trichloroethylene and its metabolites and potential modes of action. Chapters 4, 5, 6, 7, and 8 evaluate the key issues regarding liver toxicity and cancer, reproductive and developmental toxicity, neurotoxicity, respiratory tract toxicity and cancer, and immunotoxicity, respectively. However, the committee's review focused on mode-of-action information to understand how trichloroethylene might affect certain processes differently in different species. Chapter 9 discusses susceptibility to trichloroethylene and its metabolites, and Chapter 10 describes important factors in considering trichloroethylene in mixtures. Physiologically based pharmacokinetic models are evaluated in Chapter 11, and guidance is provided on future directions for model development. Finally, Chapter 12 considers issues related to dose-response assessment and quantitative assessment of risk.

Science and Decisions by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Committee on Improving Risk Analysis Approaches Used by the U.S. EPA Pdf
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 Dose—Response Relation in Pharmacology by Ronald J. Tallarida,Leonard S. Jacob Pdf
This book is designed to meet the modern need for a better understanding of drug-receptor interaction as applied to the gathering and interpretation of dose-response data. It is an introduction suitable for any student who has had a first course in pharmacology. This book is an extension of the pharmacology course into one area of what is now known as molecular pharmacology. The material included is an outgrowth of courses that we have given in recent years to health-science students in several professional schools and universities. The area of drug-receptor theory, although just a part of molecular phar macology, is already very broad. One major line of investigation is concerned with the chemical and structural nature of specific receptors and with efforts to isolate specific receptors. Another line of investigation is concerned with the kinetic theories of drug-receptor interaction, the effort there being to provide a general theory that is applicable to wide classes of drugs. We have chosen to deal with the latter. There are several reasons for our choice of topics. First, the information is very practical; that is, it permits one to use properly and consistently terms such as "efficacy," "partial agonist," "pure antagonist," "potency," "pA2'" etc., when describing drug action. Second, many students fail to appreciate the differences in and the limitations of the various theories, beginning with the classical theory of A. J. Clark, on up to the very recent allosteric theories.

Critical Aspects of EPA's IRIS Assessment of Inorganic Arsenic by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Committee on Inorganic Arsenic Pdf
The US Environmental Protection Agency (EPA) Integrated Risk Information System (IRIS) program develops toxicologic assessments of environmental contaminants. IRIS assessments provide hazard identification and dose-response assessment information. The information is then used in conjunction with exposure information to characterize risks to public health and may be used in risk-based decisionmaking, in regulatory actions, and for other risk-management purposes. Since the middle 1990s, EPA has been in the process of updating the IRIS assessment of inorganic arsenic. In response to a congressional mandate for an independent review of the IRIS assessment of inorganic arsenic, EPA requested that the National Research Council convene a committee to conduct a two-phase study. Critical Aspects of EPA's IRIS Assessment of Inorganic Arsenic is the report of the first phase of that study. This report evaluates critical scientific issues in assessing cancer and noncancer effects of oral exposure to inorganic arsenic and offers recommendations on how the issues could be addressed in EPA's IRIS assessment.

Issues in Risk Assessment by National Research Council,Division on Earth and Life Studies,Commission on Life Sciences,Committee on Risk Assessment Methodology Pdf
The scientific basis, inference assumptions, regulatory uses, and research needs in risk assessment are considered in this two-part volume. The first part, Use of Maximum Tolerated Dose in Animal Bioassays for Carcinogenicity, focuses on whether the maximum tolerated dose should continue to be used in carcinogenesis bioassays. The committee considers several options for modifying current bioassay procedures. The second part, Two-Stage Models of Carcinogenesis, stems from efforts to identify improved means of cancer risk assessment that have resulted in the development of a mathematical dose-response model based on a paradigm for the biologic phenomena thought to be associated with carcinogenesis.
Low Dose Exposures in the Environment by C. Streffer,H. Bolt,D. Follesdal,P. Hall,J.G. Hengstler,P. Jacob,D Oughton,K. Prieß,E. Rehbinder,E. Swaton Pdf
The ever-increasing release of harmful agents due to human activities have led in some areas of the world to heavy pollution. In order to protect human health and the environment, environmental standards that shall limit the release and the concentration of those toxic agents in the environment and hence the exposure to it have to be established. The related assessment and decision-making procedures have to be based on solid scientific data about the effects and mechanisms of these agents as well as on ethical, social and economic aspects. For risk evaluation, the knowledge of the dose response curve is an essential prerequisite. Dose responses without a threshold dose are most critical in this connection. Such dose responses are assumed for mutagenic and carcinogenic effects, which, therefore, dominate also the discussion in this book. In the environmentally important low dose range, risk estimation can only be achieved by extrapolation from higher doses with measurable effects. The extrapolation is accompanied with uncertainties which makes risk evaluation as well as risk communication frequently problematic. In order to ensure rational efficient and fair decisions beyond a sound scientific assessment the dialogue between disciplines, with the affected people and with the general public is necessary. In this book, the whole range of relevant and essential aspects of risk evaluation and standard setting is addressed. Starting with the ethical foundations, the sound analysis of recent scientific findings sets the frame for further reflections by theory of cognition, psychosocial sciences, and jurisprudence. The authors end up with concluding recommendations for coping with the recent problems of standard setting in the field of environmentally relevant low doses. The book is designed to a readership of scientists, legislators, administrators, and the interested public.

This is not a book about one thing. It's not a 250-page dissertation on leadership, teams or motivation. Instead, it's an agenda for building organizations that can flourish in a world of diminished hopes, relentless change and ferocious competition. This is not a book about doing better. It's not a manual for people who want to tinker at the margins. Instead, it's an impassioned plea to reinvent management as we know it—to rethink the fundamental assumptions we have about capitalism, organizational life, and the meaning of work. Leaders today confront a world where the unprecedented is the norm. Wherever one looks, one sees the exceptional and the extraordinary: Business newspapers decrying the state of capitalism. Once-innovative companies struggling to save off senescence. Next gen employees shunning blue chips for social start-ups. Corporate miscreants getting pilloried in the blogosphere. Entry barriers tumbling in what were once oligopolistic strongholds. Hundred year-old business models being rendered irrelevant overnight. Newbie organizations crowdsourcing their most creative work. National governments lurching towards bankruptcy. Investors angrily confronting greedy CEOs and complacent boards. Newly omnipotent customers eagerly wielding their power. Social media dramatically transforming the way human beings connect, learn and collaborate. Obviously, there are lots of things that matter now. But in a world of fractured certainties and battered trust, some things matter more than others. While the challenges facing organizations are limitless; leadership bandwidth isn't. That's why you have to be clear about what really matters now. What are the fundamental, make-or-break issues that will determine whether your organization thrives or dives in the years ahead? Hamel identifies five issues are that are paramount: values, innovation, adaptability, passion and ideology. In doing so he presents an essential agenda for leaders everywhere who are eager to... move from defense to offense reverse the tide of commoditization defeat bureaucracy astonish their customers foster extraordinary contribution capture the moral high ground outrun change build a company that's truly fit for the future Concise and to the point, the book will inspire you to rethink your business, your company and how you lead.
