As the discipline of ecotoxicology grows and develops, the concepts and data used are proving increasingly useful in improving the quality of risk assessment of soil pollution by professional scientists in a regulation context as well as in research. This volume illustrates how strengthening scientific basis for the ecotoxicological approach is helping substantially in environmental policy decision making. This book should be of interest to ecotoxicologists, pollution control managers, soil scientists, environmental scientists, toxicologists, applied ecologists and agriculturalists.

How is one to make good, cost-effective decisions about the management or remediation of polluted soils? The application of bioindication techniques may provide information on the availability of contaminants, and may thus help to support management decisions. In addition, the repeated application of bioindicators may reveal temporal trends and the spatial extent of the ecological effects of contaminants. This book presents a set of new approaches to the development of bioindication systems for the soil environment. The emphasis is on the use of invertebrates, as part of the soil life-support system. One of the book's main messages is that bioindicators should integrate information derived from invertebrate communities, micro-organisms and soil processes. It discusses general ecotoxicological approaches, community and systems approaches, as well as various case studies in Eastern and Western Europe and the USA.

Many industrialized and developing countries are faced with the assessment of potential risks associated with contaminated land. A variety of human activities have left their impacts on soils in the form of elevated and locally high concentrations of potential toxicants. In several cases sources have not yet been stopped and contamination continues. Decisions on the management of contaminated sites and on the regulation of chemicals in the terrestrial environment require information on the extent to which toxicants adversely affect the life support function of soils. Ecological insights into the soil as an ecosystem may support such decisions. This book reviews the latest ecological principles that should be considered in this respect.

KRIVOLUTSKY* **Department of Ecology and Ecotoxicology VrUe Universiteit, De Boelelaan 1087, 1081 HV Amsterdam, The Netherlands *Institute of Evolutionary Animal Morphology and Ecology Russian Academy of Sciences, Leninsky Prospekt 33 117071 Moscow, Russian Federation Many industrialized and developing countries are faced with the assessment of potential risks associated with contaminated land. A variety of human activities, including municipal waste disposal, industrial emissions, military testing, and agricultural practices have left their impacts on soils in the form of elevated, and locally high concentrations of toxicants. In several cases sources have not yet been stopped and contamination continues. Decisions on the management of contaminated sites require information on the extent to which toxicants adversely affect the soil ecosystem. For this purpose, it is often insufficient to extrapolate from abiotic sampling. The detection of a toxicant in the abiotic environment usually does not allow a very strong conclusion on the potential hazards.
