Book Description
Introduction to Chemical Exposure and Risk Assessment focuses on the principles involved in assessing the risks from chemical exposure. These principles include the perception of risk, an understanding of how numbers are handled, and how chemicals affect health. The book briefly describes the major sinks, such as water and air, where chemicals are introduced. This is followed by a discussion on how concentrations are estimated and risk assessments are made. A discussion of risk benefit analysis and a presentation of several case studies using the principles for assessing risks are also included.

Book Description
A state-of-the-art review of methods and procedures for assessing the risks to human health posed by environmental chemicals. Addressed to regulatory authorities, risk managers and other decision-makers, the book aims to demystify the principles of risk assessment and thus encourage wider use of this powerful tool for protecting populations. Since the detection of chemical hazards may have socioeconomic and political consequences, the book gives particular attention to methods for the accurate identification of risks and determination of their severity. The book has four chapters covering each logical step in the process of risk assessment. The first, on hazard identification, explains how data on a chemical's toxicity and mode of action can be used to determine whether the chemical will cause adverse effects on health. The strengths and limitations of different types of data are discussed together with criteria commonly used to establish causality. Methods for assessing dose-response relationships are reviewed in chapter two, which explains how to characterize the relationship between the dose administered or received and the incidence of an adverse effect. Exposure assessment is covered in the next chapter, which describes methods for determining the nature and extent of contact with chemical substances and discusses the characteristics of exposure in the general environment, in the workplace, and from consumer products. The final chapter explains the procedure of risk characterization as a decision-making tool that brings together estimates of exposure levels and risks and summarizes sources of uncertainty in the scientific data. Practical options for risk management are presented as a range of regulatory, non-regulatory, economic, and technological measures.

Book Description
Can the electric and magnetic fields (EMF) to which people are routinely exposed cause health effects? This volume assesses the data and draws conclusions about the consequences of human exposure to EMF. The committee examines what is known about three kinds of health effects associated with EMF: cancer, primarily childhood leukemia; reproduction and development; and neurobiological effects. This book provides a detailed discussion of hazard identification, dose-response assessment, exposure assessment, and risk characterization for each. Possible Health Effects of Exposure to Residential Electric and Magnetic Fields also discusses the tools available to measure exposure, common types of exposures, and what is known about the effects of exposure. The committee looks at correlations between EMF exposure and carcinogenesis, mutagenesis, neurobehavioral effects, reproductive and developmental effects, effects on melatonin and other neurochemicals, and effects on bone healing and stimulated cell growth.

Book Description
Site-specific risk assessment is the process of evaluating whether or not a site poses a risk to human health or the environment. The purpose of all hazardous waste site remediation is ultimately to render a site safe for human or ecological populations. Consequently, risk assessment, as the process used to measure the effectiveness of the remediation process, is critical to all hazardous waste-site work. Risk assessment at hazardous waste sites involves the use of standard approaches and assumptions in a reasoned, common sense manner. The purpose of this book is to provide practical guidance to people wishing to learn about, conduct, or use risk assessment procedures in evaluating hazardous waste sites. Critical issues, standard formulas and assumptions, and guidance on characterizing risk results in a useable manner are presented. The use of risk assessment as a key tool in selecting appropriate remedial options at hazardous waste sites is also described. Most attention is given to human health risks associated with exposure to toxic chemicals, but descriptions of the strategies used to estimate radiation health risks and to evaluate risks to the environment are also provided. Although most commonly applied to hazardous waste site remediation, the procedures outlined in this book are generally applicable to any situation involving a potential for health risks to an exposed population. This book provides guidance on the mechanics of risk assessment preparation and illustrates these approaches with examples. However, the focus of the book is on the subjective nature of risk assessment, the art rather than the science. The actual risk (i.e., the right answer) can never be known. Consequently, while it is valuable to attempt to obtain the best numeric solution, reasonableness and the application of common sense are equally important. The book therefore devotes a substantial amount of space to issues of uncertainty that are inherent in risk assessment, and the need to address this uncertainty.

Book Description
The field of occupational health and safety constantly changes, especially as it pertains to biomedical research. New infectious hazards are of particular importance at nonhuman-primate facilities. For example, the discovery that B virus can be transmitted via a splash on a mucous membrane raises new concerns that must be addressed, as does the discovery of the Reston strain of Ebola virus in import quarantine facilities in the U.S. The risk of such infectious hazards is best managed through a flexible and comprehensive Occupational Health and Safety Program (OHSP) that can identify and mitigate potential hazards. Occupational Health and Safety in the Care and Use of Nonhuman Primates is intended as a reference for vivarium managers, veterinarians, researchers, safety professionals, and others who are involved in developing or implementing an OHSP that deals with nonhuman primates. The book lists the important features of an OHSP and provides the tools necessary for informed decision-making in developing an optimal program that meets all particular institutional needs.

Book Description
In fact, with the control and containment of most infectious conditions and diseases of the past millennium having been achieved in most developed countries, and with the resultant increase in life expectancies, much more attention seems to have shifted to degenerative health problems. Many of the degenerative health conditions have been linked to thousands of chemicals regularly encountered in human living and occupational/work environments. It is important, therefore, that human health risk assessments are undertaken on a consistent basis - in order to determine the potential impacts of the target chemicals on public health.
