The regulation of potentially hazardous substances has become a controversial issue. This volume evaluates past efforts to develop and use risk assessment guidelines, reviews the experience of regulatory agencies with different administrative arrangements for risk assessment, and evaluates various proposals to modify procedures. The book's conclusions and recommendations can be applied across the entire field of environmental health.

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.

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.

This book provides an easy, but comprehensive and rigorous access to the main concepts, terminology, methods and procedures of risk analysis intended for all those involved in the EU policy and regulatory decision making on risks. It establishes a common ground of knowledge which enables a more informed dialogue on risks, a closer collaboration between decision makers and scientists and a better appraisal of the potential and limits of risk science. The book also brings together in an accessible way much multidisciplinary knowledge which had been dispersed over many technical documents and specialist books. The EU is in the front line of health, safety and environmental risk management. GMOs, food safety, hazardous chemicals, climate change, radiation hazards, are just a few of the popular risk issues addressed by the EU through policy and regulatory measures. The risk analysis paradigm, including risk assessment, management and communication has been at the core of the EU decision making for a long time already. EU Institutions strive for a science-based approach to risk management. Nevertheless, the dialogue and collaboration on risk issues between policy makers, stakeholders and scientists are still difficult and the potential and limits of science in support of decision making, as well as the basic concepts of risk analysis are not fully understood outside the narrow specialist circles.

This publication presents recent OECD papers on risk and regulatory policy. They offer measures for developing, or improving, coherent risk governance policies.
