How can environmental regulators use information on 48-hour toxicity tests to predict the effects of a few minutes of pollution? Or, at the other extreme, what is the relevance of 96-hour toxicity data for organisms that may have been exposed to a pollutant for six months or more? Time to event methods are the key to answering these types of questions. Risk Assessment with Time to Event Models is the first comprehensive treatment of these methods in the context of ecological risk assessment. Leading experts from industry, academia, and government regulatory agencies explain how these methods can be used to extract more useful information from laboratory data than is present in simple summary statistics like 48-h LC50. The book offers a clear introduction to the field through several approaches, from the introductory to the more mathematical. Risk Assessment with Time to Event Models demonstrates the relevance of time in the analysis and reporting of toxicity data through the use of practical examples from the field of environmental toxicology. It also incorporates helpful analogies from other disciplines that commonly use time to event modeling.

Most ecological risk assessments consider the risk to individual organisms or organism-level attributes. From a management perspective, however, risks to population-level attributes and processes are often more relevant. Despite many published calls for population risk assessment and the abundance of available scientific research and technical tools assessing risks to populations, risk assessors worldwide still have difficulty determining how population level considerations can be integrated into environmental decision-making. Population-Level Ecological Risk Assessment establishes a framework for goals, methods, and data needs for different assessment applications and for integrating population-level risk assessment into risk management decisions. Beginning with a summary of legal, regulatory, business, and other contexts, the book presents population-level ecological risk assessment as an internationally recognized, science-based tool and offers specific recommendations for using this tool to support environmental management decisions. It gives clear, explicit, operational population assessment definitions and explains the relevance of density dependence, genetics, and spatial considerations, as well as applicable lessons from conservation biology and natural resource management. The authors provide a "tool box" of empirical and modeling methods and describe the general approaches, assumptions, data requirements, strengths, and limitations of each method. They establish a working foundation for designing and conducting population-level ecological risk assessments consistent with North American, European, and Japanese risk management approaches. The book concludes by highlighting key considerations needed to improve the scientific quality and interpretation of assessments. Detailed appendices include examples of population-level assessment approaches applicable to specific environmental management contexts, a modeling case study, and a supplemental reading list.

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 chemicals, the remediation of contaminated sites, the monitoring of importation of exotic organisms, the management of watersheds, and other environmental management issues. Delineating the processes for performing an ERA, the book begins by defining the field, then goes on to describe its relationship to other environmental assessment practices and its organizational framework. The book also includes a chapter on ecological epidemiology, which has previously been treated as a type of ERA, but is now recognized as a distinct practice in itself. It explores important concepts in the ERA process including probability, uncertainty, scale, mode of action and multiple causes. Reflecting changes in the field, the book’s scope has been broadened to include discussions of the application of ERA to agents other than chemical contaminants. The multitude of illustrative figures provides a flavor for the diverse practice of ERA. The author has re-organized the material, presenting a unitary process of ERA that is applicable to various problems, scales, and mandates. He keeps the emphasis squarely on providing clear, scientifically sound, and unbiased technical advice on the risks from chemicals and chemical mixtures.

Environmental impact assessment (EIA) is now firmly established as an important and often obligatory part of proposing or launching any development project. Delivering a successful EIA needs not only an understanding of the theory but also a detailed knowledge of the methods for carrying out the processes required. Peter Morris and Riki Therivel bring together the latest advice on best practice from experienced practitioners to ensure an EIA is carried out correctly. This new edition: • explains how an EIA works and how it should be carried out • demonstrates the relationship of the EIA to socio-economic, environmental and ecological systems • includes completely updated legislative and policy contexts • has added explanations of shared and integrative methods including a new chapter on EIA and sustainability. Invaluable to undergraduate and MSc students of EIA in planning, ecology, geography and environment courses, this third edition of Methods of Environmental Impact Assessment is also of great use to planners, EIA practitioners and professionals seeking to update their skills.
