Book Synopsis Principles for the Assessment of Risks to Human Health from Exposure to Chemicals by : United Nations Environment Programme

Download or read book Principles for the Assessment of Risks to Human Health from Exposure to Chemicals written by United Nations Environment Programme. This book was released on 1999. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Introduction to Chemical Exposure and Risk Assessment by : W.Brock Neely

Download or read book Introduction to Chemical Exposure and Risk Assessment written by W.Brock Neely. This book was released on 2020-04-28. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Public Health Risk Assessment for Human Exposure to Chemicals written by K. Asante-Duah. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Risk Assessment by : Peter LaGoy

Download or read book Risk Assessment written by Peter LaGoy. This book was released on 1994-12-31. Available in PDF, EPUB and Kindle. Book excerpt: 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.
