Available in PDF, EPUB and Kindle. Book excerpt: En el pasado, la sociedad humana obtenía los recursos de la Tierra de forma sostenible, pero por las altas concentraciones poblacionales, comenzaron a aparecer distintos tipos de contaminación del agua, a causa de las aglomeraciones urbanas y la consiguiente actividad humana. La revolución industrial del siglo XIX alteró el equilibrio entre el ser humano y la naturaleza, surgiendo la contaminación y la degradación medioambiental. Este desequilibrio llegó a su límite cuando la contaminación ocupó la extensión geográfica de todo el planeta. La ecotoxicología surge por la evolución de la Toxicología hacia el estudio del entorno en el transcurso del desarrollo industrial. Pretende ser una aportación más al estudio del Medio Ambiente, dentro de la creciente demanda de bibliografía sobre contaminación, toxicología, polutantes, biocidas, etc.
Download or read book Ecotoxicology Ecological Risk Assessment and Multiple Stressors written by Gerassimos Arapis and published by Springer Science & Business Media. This book was released on 2006-02-09 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of ecotoxicology and the practice of ecological risk assessment are evolving rapidly. Ecotoxicology as a subject area came into prominence in the 1960s after the publication of Rachel Carson's book on the impact of pesticides on the environment. The rise of public and scientific concern for the effects of chemical pollutants on the environment in the 1960s and 1970s led to the development of the discipline of ecotoxicology, a science that takes into account the effects of chemicals in the context of ecology. Until the early 1980s, in spite of public concern and interest among scientists, the assessment of ecological risks associated with natural or synthetic pollutants was not considered a priority issue by most government. However, as the years passed, a better understanding of the importance of ecotoxicology emerged and with it, in some countries, the progressive formalization of an ecological risk assessment process. Ecological risk assessment is a conceptual tool for organizing and analyzing data and information to evaluate the likelihood that one or more stressors are causing or will cause adverse ecological effects. Ecological risk assessment allows risk managers to consider available scientific information when selecting a course of action, in addition to other factors that may affect their decision (e. g. , social, legal, political, or economic). Ecological risk assessment includes three phases (problem formulation, analysis, and risk characterization).
Download or read book Community Ecotoxicology written by William H. Clements and published by John Wiley & Sons. This book was released on 2003-02-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.'
Download or read book Multiple Stresses in Ecosystems written by Jr. Cech and published by CRC Press. This book was released on 2017-11-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is the evaluation of toxic effects within the environment, typically within one specific ecosystem, like a forest, stream, or lake. For years now, ecotoxicological studies have tended to focus on one toxicant at a time. But that isn't how an ecosystem encounters toxicants (or stresses): there may be several elements at work in the air, several more in the water, and still more already within the soil of any given ecosystem, and all have some level of toxic influence on that ecosystem. Multiple Stresses in Ecosystems presents the state-of-the-art in determining the effects of these multiple impacts upon ecosystems. Resulting from a vanguard conference originally held in 1993 at UC Davis, this new work is divided into three sections that present methodolgies for assessing the health of an ecosystem; the effects of multiple toxicological impacts upon an ecosystem, and which tools are worth using to assess these dangers. Environmental scientists, chemists, toxicologists, risk analysts, and probably the entire membership of SETAC will find need for this book, as will wetlands scientists, ecologists, and research biologists.

Download or read book Environmental Ecology written by Bill Freedman and published by Elsevier. This book was released on 2013-09-25 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Ecology: The Impacts of Pollution and Other Stresses on Ecosystem Structure and Function deals with environmental studies on the ecological impacts of anthropogenic stresses. The book discusses more particularly the ways that anthropogenic or natural influences affect the quality of the inorganic and biotic components of the biosphere, as well as the human environment. The text discusses the sources of air pollution, the different toxic elements (naturally occurring contamination or anthropogenic sources), and acidifying substances or "acid rain." The author also cites several studies that deal with the reclamation of acidified bodies of water. Another topic the author addresses is declining forest areas; he then cites several case studies of this occurrence, such as those by Fowells, 1965; Hepting, 1971; and Auclair, 1987. The text also investigates the ecological effects of oil pollution caused during the refining process and transportation. The author then examines the general response patterns to ecological stress. The text is intended for advanced students of environmental ecology and environmental science, as well as for ecologists, environmentalists, and urban planners and officials.
Download or read book Ecotoxicology Problems and Approaches written by Simon A. Levin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is the science that seeks to predict the impacts of chemi cals upon ecosystems. This involves describing and predicting ecological changes ensuing from a variety of human activities that involve release of xenobiotic and other chemicals to the environment. A fundamental principle of ecotoxicology is embodied in the notion of change. Ecosystems themselves are constantly changing due to natural processes, and it is a challenge to distinguish the effects of anthropogenic activities against this background of fluctuations in the natural world. With the frustratingly large, diverse, and ever-emerging sphere of envi ronmental problems that ecotoxicology must address, the approaches to individual problems also must vary. In part, as a consequence, there is no established protocol for application of the science to environmental prob lem-solving. The conceptual and methodological bases for ecotoxicology are, how ever, in their infancy, and thus still growing with new experiences. In deed, the only robust generalization for research on different ecosystems and different chemical stresses seems to be a recognition of the necessity of an ecosystem perspective as focus for assessment. This ecosystem basis for ecotoxicology was the major theme of a previous pUblication by the Ecosystems Research Center at Cornell University, a special issue of Environmental Management (Levin et al. 1984). With that effort, we also recognized an additional necessity: there should be a continued develop ment of methods and expanded recognition of issues for ecotoxicology and for the associated endeavor of environmental management.
Download or read book Applied Ecotoxicology written by Johann F. Moltmann and published by CRC Press. This book was released on 2020-09-10 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new book illustrates the complex nature of ecotoxicological issues, using pesticides as an example. It focuses on the assessment and monitoring of the amounts of pollutants in the environment and the subsequent damage. The text provides the basic information and methodology to help the reader determine the extent of ecological damage caused by a given substance. Legislatures in industrialized countries have taken the initiative in dealing with these issues by formulating new priorities for environmental protection. Applied Ecotoxicology describes these regulatory efforts, which are separated by their two distinct objectives: those that seek to expand the scope of protection against the pollutants' negative impacts, and those shifting the level of investigation from the individual to the ecosystem. Pollutants are only one of a number of different environmental factors to which organisms are exposed. Their impact in the field is presented in the context of other forms of human intervention in the environment. The increasing use of pesticides in tropical regions, a growing ecotoxicological concern in these countries, is also discussed.
Download or read book Ecotoxicology written by Frank Moriarty and published by Academic Press. This book was released on 1999-04-30 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology, Third Edition discusses the ecological effects of pollutants: the ways in which ecosystems can be affected, and current attempts to predict and monitor such effects. The emphasis is on ecosystems; therefore toxicological approaches are critically assessed. Following a brief introduction to the principal characteristics of both pollutants and ecosystems, the various ecosystem components are considered in more detail. Populations, communities and gene pools are examined with an emphasis on the ways in which pollutants affect them specifically. The indirect effects of pollution are considered separately in a new chapter with particular attention paid to the mechanisms and biological effects of global warming. A discussion of the methods used to predict and to monitor the effects of pollutants, some illustrative examples of pollution problems and a final summary discussion, complete the book. A classic proven by its second edition Still the only book to properly integrate ecological principles with chemistry/biochemistry Focuses on the interaction between ecology and toxicology Designed for use by toxicologists with no ecology training, and for ecologists with no toxicology training There is a new chapter on pollutants in habitats and global warming
Download or read book Ecological Assessment of Environmental Degradation Pollution and Recovery written by O. Ravera and published by Elsevier. This book was released on 2012-12-02 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ispra Course on Ecological Assessment of Environmental Degradation, Pollution and Recovery'' was structured according to the following topics: (a) terrestrial and aquatic ecosystem concept; (b) structure, functions and evolution of the ecosystem in relation to the natural and anthropogenic influences, and (c) concept of stress, assessment and restoration of terrestrial and aquatic ecosystems. These general concepts were developed in a series of lectures presented by well-known experts in their specific fields, taking into account the ecological principles and environmental management. For the various aspects of the environmental problems, the state-of-the-art, the principles of restoration techniques, the results obtained by their application and the research needs to acquire a better knowledge of the ecological processes, were discussed. The lectures were illustrated by several case studies concerning forests, lakes, reservoirs, rivers, soil and the interrelations between air and terrestrial and aquatic ecosystems.This book contains the lectures presented at the course, reviewed by the authors, and complemented throughout with numerous figures and tables.
