Integrating ecotoxicological concepts across a range of hierarchical levels, Ecotoxicology: A Comprehensive Treatment focuses on the paradigms and fundamental themes of ecotoxicology while providing the detail and practical application of concepts often found in more specialized books. By synthesizing the best qualities of a general textbook and the narrower, more specific scope of a technical reference, the authors create a volume flexible enough to cover a variety of instructional vantages and thorough enough to engender a respect for the importance of understanding and integrating concepts from all levels of biological organization. Divided into six sections, the book builds progressively from the biomolecular level toward a discussion of effects on the global biosphere. It begins with the fundamentals of hierarchical ecotoxicology and vantages for exploring ecotoxicological issues. The second section introduces organismal ecotoxicology and examines effects to biochemicals, cells, organs, organ systems, and whole organisms, and bioaccumulation and bioavailability of contaminants. Population ecotoxicology, section three, places the discussion in the larger context of entire populations by analyzing epidemiology, population dynamics, demographics, genetics, and natural selection. Section four encompasses issues of community ecotoxicology. This section presents biotic and abiotic factors influencing communities, biomonitoring and community response, and the application of multimetric and multivariate approaches. Section five evaluates the entire ecosystem by describing assessment approaches, identifying patterns, analyzing relationships between species, and reviewing the effects of global atmospheric stressors. A detailed conclusion integrating the concepts discussed and promoting a balanced assessment of the overarching paradigms rounds out the coverage in section six.

Ecotoxicology is the study of the effects of toxicants on ecological systems. Ecological effects of contaminants may occur at several levels of biological organisation, from individual organisms to the entire biosphere. Communities consist of interacting populations that overlap in time and space. Thus, community ecotoxicology is concerned with effects of contaminants on communities. This is one of a series of five books that will provide a comprehensive treatment of field ecotoxicology, it provides important insights into how contaminants affect the distribution and abundance of organisms in nature. * Both authors are well known highly respected scientists in the field. * The first book to be dedicated to 'community ecotoxicology.'

Quantitative Ecotoxicology, Second Edition explores models and methods of quantitative ecotoxicology at progressively higher biological scales using worked examples and common software packages. It complements the author’s previous books, Fundamentals of Ecotoxicology, Third Edition and Ecotoxicology: A Comprehensive Treatment. Encouraging a more rigorous inferential approach to research, the book examines the quantitative features of the science of ecotoxicology. The first chapters lay the foundation by introducing fundamental concepts and definitions. The author traces the historical perspective, rationale, and characteristics of scientific ecotoxicology as well as the general measurement process. He also considers methodologies for defining and controlling variance, which could otherwise exclude valid conclusions from ecotoxicological endeavors. The book then discusses ecotoxicological concepts at increasing levels of ecological organization and outlines quantitative methods used to measure toxicant accumulation and effects. Reflecting the importance of establishing type I and type II error rates, it highlights design issues, particularly sample size and power estimation. The final chapter summarizes the book with a brief discussion of ecotoxicology from a nonregulatory perspective. Extensively updated, this second edition has been expanded to include terrestrial as well as aquatic ecotoxicology. Requiring only a basic knowledge of statistics, this highly readable book is suitable for graduate students and researchers as well as practicing environmental scientists and engineers. It guides readers to better understand the fate and effects of toxicants in the biosphere—and helps them frame this understanding in quantitative terms. What’s New in This Edition More than 40 new figures and 20 new worked examples Updated measurement quality methods and software Expanded coverage of synecological models and methods More integration of Bayesian concepts Appendices for power analysis and basic matrix methods Additional mixture toxicity and up-and-down methods Greatly expanded discussion of significance testing Expanded discussion of metapopulations Matrix tools for population demography Light isotope-based models for trophic transfer of toxicants Inclusion of metacommunity and SHE analysis techniques R script examples by Eduard Szöcs (University Koblenz-Landau) available at http://edild.github.io/blog/categories/quantitative-ecotoxicology-with-r/

The application of nanotechnology in different consumer products has delivered new products with highly desirable properties, but at same time has opened a new window for a wide group of emerging contaminants and a new type of human exposure which needs to be assessed. Most of the current human toxicological information on nanomaterials comes from nano-sized particles in air, and their effects via inhalation. Other routes of human exposure, such as water and food, and the effects on human health and the environment have been less studied. It is the recent research in these areas that is highlighted here in one of the first books covering the analysis and ecotoxicological evaluation of nanomaterials in food and the environment, with both matrices being of considerable interest. In addition to providing a global summary of recent research, this book shows how widely used chromatographic and spectroscopic methods can be added to the analytical arsenal of microscopic techniques that have commonly been used to characterize nanomaterials. Describes the analytical techniques used to characterize nanomaterials and their applications in environmental or food samples Includes analysis and ecotoxicological evaluation of nanomaterials in food and environmental matrices Takes a detailed look at the research on emerging fields of human exposure to nanomaterials and their environmental risks

The Nature and Use of Ecotoxicological Evidence: Natural Science, Statistics, Psychology, and Sociology examines how toxicologists and environmental professionals come to understand and make decisions about possible harm from pollutants. Drawing on concepts and techniques from the natural, social and mathematical sciences, the book emphasizes how pollutant-related evidence is gathered, assessed, communicated and applied in decision-making. Each chapter begins with a real-world example before exploring fundamental cognitive, social, statistical or natural science concepts to explain the opening example. Methods from other disciplines for recognizing, reducing or removing the influence of impediments in wise decision-making are highlighted in each chapter. Misreading evidence by the scientific community, and miscommunication to regulators and the public, remain major impediments to wise action in pollution issues. Which evidence comes to dominate the dialogue among scientists, regulators and decision makers depends on social and scientific dynamics. Yet psychological and sociological factors that influence the movement of evidence through scientific communities to regulators receive cursory discussion by professionals unfamiliar with the sociology literature. Toxicologists, environmental scientists, psychologists and professionals and students across the sciences will find the book useful for understanding how evidence is generated, assessed and communicated in their own fields. Includes groundbreaking research synthesizing information from across the sciences to understand the decision-making process Provides real life examples and uses theoretical concepts to analyze them in clear, direct language Encourages critical thinking about complex problems
