Environmental indicators are the first line of warning against hazards caused by humans or nature catastrophes to prevent diseases and death of living organisms. The present book covers a large variety of environmental indicators from physical-chemistry through economical, bioinformatics, electromagnetic irradiation and health aspects, all dealing with environmental pollution. This volume has been intended to environmentalists, engineers, scientists and policy makers as well to anybody interested in the latest development in the indicator field.

Researchers and agencies collect reams of objective data and authors publish volumes of subjective prose in attempts to explain what is meant by environmental quality. Still, we have no universally recognized methods for combining our quantitative measures with our qualitative concepts of environ ment. Not all of our environmental goals should be reduced to mere numbers, but many of them can be; and without these quantitative terms, we have no way of defining our present position nor of selecting positions we wish to attain on any logically established scale of environmen tal values. Stated simply, in our zeal to measure our environment we often forget that masses of numbers describing a system are insufficient to understand it or to be used in selecting goals and priorities for expending our economic and human resources. Attempts at quantitatively describing environmental quality, rather than merely measuring different environmental variables, are relatively recent. This condensing of data into the optimum number of terms with maximum information content is a truly interdisciplinary challenge. When Oak Ridge National Laboratory initiated its Environmental Program in early 1970 under a grant from the National Science Foundation, the usefulness of environmental indicators in assessing the effects of technology was included as one of the initial areas for investigation. James L. Liverman, through his encouragement and firm belief that these indicators are indispensable if we are to resolve our complex environmental problems, deserves much of the credit for the publication of this book.

This report is the summary of the fourth workshop of The Roundtable on Environmental Health Sciences, Research, and Medicine. Environmental Indicators: Bridging the Chasm Between Public Health and the Environment, continues the overarching themes of previous workshops on rebuilding the unity of health and the environment. The purpose of the workshop was to bring people together from many fields, including federal, state, local, and private partners in environmental health, to examine potential leading indicators of environmental health, to discuss the proposed national health tracking effort, to look into monitoring systems of other nations, and to foster a dialogue on the steps for establishing a nationwide environmental health monitoring system. This workshop brought together a number of experts who presented, discussed, and debated the issues surrounding the implementation of a monitoring system.

Finding and using indicators that are most suited for tracking progress, raising awareness and supporting analysis is a challenge. Indicators need to be used in appropriate contexts and should ideally be fit-for-purpose. For example, indicators which are best used for awareness-raising cannot be used for monitoring policy goals. This report presents a short review of different indicators typically encountered by environmental policy makers. General advice is provided regarding their uses. In the second part of the report, an overview of the environmental-economic accounting work of the Nordic statistical institutes is presented. Lessons learned from the development of these accounts as well as ideas for future work are described. These types of environmental accounts provide a framework for developing information about the connections between the economy and the environment. The study was commissioned by the Nordic Council of Ministers and conducted by the national statistical agencies in the Nordic countries, led by Statistics Norway and Statistics Sweden.

The field of ecosystem health explores the interactions between natural systems, human health, and social organization. As decision makers require a sound, modular approach to environmental management and sustainable development, ecosystem health assessment indicators are increasingly used across any number of applications.
