As debates over how relative risk can be used to shape landscape-scale environmental management intensify, Regional-Scale Risk Assessment demonstrates the capabilities of RRM using nine case studies in the Pacific Northwest, Pennsylvania, Brazil, and Tasmania. The authors use a process of ranking and filters to interrelate different kinds of risks and illustrates how these relative risks are defined, mapped, and analyzed to determine remediation and management priorities. This book provides detailed descriptions for each step of RRM-from the determination of assessment goals to documentation, evaluation, and communication with decision-makers-that can benefit practitioners in environmental risk assessment and related fields worldwide.

In Alternative Ecological Risk Assessment theauthor, Lawrence V. Tannenbaum, provides a critical review ofcurrent practices in the ecological risk assessment field andproposes alternatives that are supported by established science andkeen observation. It is hoped that this approach will pave the wayto a greater understanding of what appropriate and usefulecological assessment for contaminated sites should entail. Hedemonstrates that in most cases current practices do not providefor an assessment of ecological risk, and moreover, thatendeavoring to assess ecological risk is actually an unnecessaryundertaking at conventional hazardous waste sites. (Hestates, for example, that the concept of scale is often ignored bypractitioners, questions why animals like deer are routinelyassessed at 5-acre sites, and challenges the ecotoxicology datacurrently used.) The book is aimed at students and professionals in the fields ofenvironmental science, ecology, ecotoxicology, and health riskassessment.

An important guide to assessing and managing the environment from a landscape perspective Ecological relationships are nested within the landscape. Identifying the relevant spatial and temporal scales is critical for an effective understanding of ecological functions that human societies depend upon. Moreover, human encroachment into natural areas, or changes in climate, can alter spatial relationships, which in turn can negatively affect vital plant and wildlife patterns—and weaken economic structures needed to sustain human societies. This book is the first to combine multiple disciplines into one cohesive strategy to study these crucial connections, and looks toward building a social paradigm that embraces the dynamics of ecological systems. This book: Integrates landscape ecology, environmental risk assessment, valuation of ecological goods and services, and environmental management decision processes into one single source Includes chapters on quantitative measures, Bayesian modeling,¿economic analysis, and sustainable landscapes Covers marine, forest, agricultural, and pharmaceutical risk assessment Has a chapter on predicting climate change risk to ecosystems Has a companion ftp site with color graphics, animations, and risk assessment tools With material that is accessible across all knowledge levels, Environmental Risk Assessment and Management from a Landscape Perspective moves beyond looking solely at chemical contaminants to diagnose environmental threats, and aims to accomplish practical risk assessment in a manner that supports long-term sustainable management.

After fifteen years and three editions, Introduction to Environmental Toxicology: Molecular Substructures to Ecological Landscapes has become a standard that defines the field of environmental toxicology, and the fourth edition is no exception. The authors take an integrated approach to environmental toxicology that emphasizes scale and context as important factors in understanding effects and management options. New in the Fourth Edition: New author, Dr. Ruth M. Sofield 8-page color insert New chapter on fate and transport of contaminants Emphasis on the use of all types of models in understanding how nature works Revised sections on synergy and atrazine toxicity Updated coverage of the analysis of impacts to populations, communities and ecosystems Enlarged risk assessment chapter with an in-depth description of a regional scale risk assessment This edition benefits from the insight of a new author, Dr. Ruth M. Sofield, who prepared the new chapter on the fate and transport of contaminants. The relationship between structure and toxicological properties has been a major theme of this book since its inception and this new chapter expands this fundamental concept to include fate and transport. In the early chapters the use of models in science is discussed and this theme carries throughout the rest of the book. So much has changed in the fifteen years since the publication of the first edition. The mid-1990s seem so long ago, when our understanding of environmental toxicology was very basic. Ecological risk assessment was in its very early stages and the consideration of the effects of toxicants on landscapes was only beginning. Computation was still hard, genes stayed put, and it was only becoming recognized that xenobiotics could have hormonal effects — developments that are taken for granted in this edition. Written by authors who teach this subject, a feature that is reflected in their straightforward style, the book provides a foundation for understanding environmental toxicology and its application.

Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.

The Environmental Monitoring and Assessment Program was created by EPA to develop the capability for tracking the changing conditions of our natural resources and to give environmental policy the advantages ofa sound scientific understanding of trends. Former EPA Administrators recognized early that contemporary monitoring programs could not even quantify simple unknowns like the number of lakes suffering from acid rain, let along determine if national control policies were benefiting these lakes. Today, adding to acidification impacts are truly complex problems such as determining the effects of climate change, of increases in ultraviolet light, toxic chemicals, eutrophication and critical habitat loss. Also today, the Government Performance and Results Act seeks to have agencies develop performance standards based on results rather than simply on levels of programmatic activities. The charge to EMAP of ecosystems is, therefore, the same today as it was a with respect to measuring the condition decade ago. We welcome the increasing urgency for sound scientific monitoring methods and data by efforts to protect and improve the environment. Systematic nationwide monitoring of natural resources is more than anyone program can accomplish, however. In an era of declining budgets, it is crucial that monitoring programs at all levels of government coordinate and share environmental data. EMAP resources are dwarfed by the more than $500 million spent on federal monitoring activities each year.
