This book introduces various mathematical models used in ecological risk assessment, primarily discussing models used in hazard assessment. The book aims to link ecology and conservation biology with risk assessments, bringing together the knowledge of ecotoxicology and ecology for effective risk assessment. The first part describes population-level assessment in ecological risk assessment. The chapters cover current methodologies for ecological risk assessment, individual-level assessment, population dynamics models for population-level assessment, case studies, mathematical models for population extinctions, the derivation of mean time to extinction (MTE) and their case studies. The second part of the book discusses the mathematical models involved in hazard assessments. It introduces the method of risk assessment using species sensitivity distributions (SSDs), hazard assessment of metals, chemical mixtures using the Michaelis-Menten equation, basic elements of statistics and related topics. Expected readers are risk assessors in governments and public sectors, students and young researchers interested in environmental science. The book is made accessible and easy to follow by beginners in mathematical biology and theoretical ecology.

Human and Ecological Risk Assessment: Theory and Practice assembles the expertise of more than fifty authorities from fifteen different fields, forming a comprehensive reference and textbook on risk assessment. Containing two dozen case studies of environmental or human health risk assessments, the text not only presents the theoretical underpinnings of the discipline, but also serves as a complete handbook and "how-to" guide for individuals conducting or interpreting risk assessments. In addition, more than 4,000 published papers and books in the field are cited. Editor Dennis Paustenbach has assembled chapters that present the most current methods for conducting hazard identification, dose-response and exposure assessment, and risk characterization components for risk assessments of any chemical hazard to humans or wildlife (fish, birds, and terrestrials). Topics addressed include hazards posed by: Air emissions Radiological hazards Contaminated soil and foods Agricultural hazards Occupational hazards Consumer products and water Hazardous waste sites Contaminated air and water The bringing together of so many of the world's authorities on these topics, plus the comprehensive nature of the text, promises to make Human and Ecological Risk Assessment the text against which others will be measured in the coming years.

What data is needed to complete a quantitative risk assessment for environmental and public health? How accurate does a quantitative risk assessment have to be? How confident does a risk assessor need to be when presenting risk estimates to a decision maker? Find out the answers to these questions and more with Comparative Environmental Risk Assessment, the first major commercial publication that describes the current state of the art in comparative environmental risk assessment. This book examines the problems involved in such analyses and offers ideas and thoughts for future development. The book examines major problems in this area and covers all aspects of the environment, including human and ecological health. Comparative Environmental Risk Assessment is an excellent guide for risk assessment experts, environmentalists, regulators, planners, legislators, scientists in industry, instructors, and students.

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.

With contributions from a wide array of economists, ecologists, and government agency professionals, Economics and Ecological Risk Assessment: Applications to Watershed Management provides a multidisciplinary approach to environmental decision-making at a watershed level. It introduces the fields of ecological risk assessment (ERA) and economic ana

The definitive reference in its field, Ecological Risk Assessment, Second Edition details the latest advances in science and practice. In the fourteen years since the publication of the best-selling first edition, ecological risk assessment (ERA) has moved from the margins into the spotlight. It is now commonly applied to the regulation of c

Rice is cultivated throughout the world under submerged conditions. The high water requirements and the heavy pesticide load used in rice paddies worldwide have resulted in contamination of associated surface water, such as streams, ditches, rivers and lakes. The uniform risk assessment approach which has been developed for other crops is not applicable to rice paddies, because of the specific conditions applied to rice cultivation. Pesticide Risk Assessment in Rice Paddies: Theory and Practice fills the gap in information on this subject. Written by experts, this book summarizes the methods used for pesticide risk assessment in rice paddies, the limitations and problems encountered and future developments. It also examines the various agronomic, pesticide application and risk assessment approaches used in different rice cultivated zones in Asia, America and Europe and is an essential reference for those working in this area.* The only up-to-date book dealing with pesticide risk assessment in the flooded conditions of rice paddies* Offers guidelines on the use and application of existing modeling tools, specific for rice cultivation* Presents the differences and similarities in rice cropping systems and how these relate to pesticide risk assessment

A Special Publication of the Society of Environmental Toxicology and Chemistry (SETAC) Aquatic Mesocosm Studies in Ecological Risk Assessment discusses the methods currently used for conducting simulated field studies and provides a series of case histories in which mesocosm type studies have been used to assess the impact of pesticides on aquatic ecosystems. Specific chapters address the dosing and exposure components of such studies and how they influence experimental design. Advantages and disadvantages of various statistical designs are addressed in detail. Regulatory aspects of the design and interpretation of these studies are also covered. The book will be a superb reference for aquatic biologists, ecologists, toxicologists, environmental toxicologists, environmental chemists, and regulatory personnel.

At the heart of environmental protection is risk assessment: thelikelihood of pollution from accidents; the likelihood of problemsfrom normal and abnormal operation of industrial processes; thelikely impacts associated with new synthetic chemicals; and so on.Currently, risk assessment has been very much in the news--therisks from BSE and E. coli, and the public perception of risks fromnuclear waste, etc. This new publication explains how scientificmethodologies are used to assess risk from human activities and theresultant objects and wastes, on people and the environment.Understanding such risks supplies crucial information--to framelegislation, manage major habitats, businesses and industries, andcreate development programmes. Unique in combining the science of risk assessment with thedevelopment of management strategies. Covers science and social science (politics, economics,psychology) aspects. Very timely - risk assessment lies at the heart of decisionmaking in various topical environmental questions (BSE, Brent Spar,nuclear waste).
