Book Synopsis Comparison of Laboratory Microcosms and Field Responses to Copper by : MC. Harrass
Download or read book Comparison of Laboratory Microcosms and Field Responses to Copper written by MC. Harrass and published by . This book was released on 1985 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a biological model, a Standardized Aquatic Microcosm has demonstrated trophic interactions and community recovery after pesticide treatment. Daphnia magna were temporarily eliminated by treatment with 0.5 mg/L copper, leading to changes in algal and rotifer densities. Algae were severely affected by treatment with 2.0 mg/L copper, demonstrating altered dominance and productivity. Recovery of treated communities after inactivation or isolation of active toxicant was demonstrated by populations attaining densities equivalent to control communities. Comparison with published studies of natural communities treated with copper indicates that similar trophic interactions have often been demonstrated, although field studies suggested that responses are quite variable.

Book Synopsis Ecological Microcosms by : Robert J. Beyers
Download or read book Ecological Microcosms written by Robert J. Beyers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Microcosms is a seminal work which reviews the expanding field of enclosed ecosystem research, and relates the results and models of microcosm studies to general concepts in ecology. Microcosms are miniaturized pieces of our biosphere, ranging from streams and lakes to terraria, agroecosystems, and waste systems. The study of these simplified ecosystems is providing provocative insights into ecological principles as well as issues of environmental management and global stability. The authors have used the well-known thermodynamic approach of H.T. Odum and numerous computer simulations. The book also includes an evaluation of alternative mesocosm approaches for the support of humans in space, as well as appendices to aid in the teaching of environmental concepts using student-created microcosms. Ecological Microcosms will be of interest to ecologists, environmental engineers, policy makers and environmental managers, space scientists, and educators. Robert J. Beyers is a Professor of Biology at the University of South Alabama. Howard T. Odum is Graduate Research Professor of Environmental Engineering Sciences at the University of Florida, and was awarded, with Eugene Odum, the 1987 Crafoord Prize in the Biosciences.

Book Synopsis Community Toxicity Testing by : John Cairns
Download or read book Community Toxicity Testing written by John Cairns and published by ASTM International. This book was released on 1986 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although community level toxicity testing is now being used for practical purposes, it is not the intent of this book to espouse the use of community level testing in all situations or to replace single-species tests that are the best source of information on growth, reproductive success, behavior, and a variety of other end points. On the other hand, since field validation of laboratory predictions is becoming increasingly important and since community level testing offers the possibility of validation by using more comparable or identical end points in complex natural systems, which is not possible for single-species tests, it is now worthy of attention by ASTM members.

Book excerpt: Research into ecotoxicology can be classified into three fundamental concerns: abiotic factors, which characterize the physicochemistry of environments; biotic factors, relating to biological structures and functions; and contamination factors, which define the modes of pollution of ecosystems. The most significant research methodologies currently being developed in aquatic ecotoxicology are presented, specifically experimental approaches in the laboratory

Book Synopsis Freshwater Field Tests for Hazard Assessment of Chemicals by : Ian R. Hill
Download or read book Freshwater Field Tests for Hazard Assessment of Chemicals written by Ian R. Hill and published by CRC Press. This book was released on 2018-05-04 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater field tests are an integral part of the process of hazard assessment of pesticides and other chemicals in the environment. This book brings together international experts on microcosms and mesocosms for a critical appraisal of theory and practice on the subject of freshwater field tests for hazard assessment. It is an authoritative and comprehensive summary of knowledge about freshwater field tests, with particular emphasis on their optimization for scientific and regulatory purposes. This valuable reference covers both lotic and lentic outdoor systems and addresses the choice of endpoints and test methodology. Instructive case histories show how to extrapolate test results to the real world.

Book Synopsis Progress in Standardization of Aquatic Toxicity Tests by : Amadeu Soares
Download or read book Progress in Standardization of Aquatic Toxicity Tests written by Amadeu Soares and published by CRC Press. This book was released on 1993-06-16 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in Standardization of Aquatic Toxicity Tests provides a critical evaluation of the level of standardization achieved by freshwater and marine ecotoxicity tests used to evaluate potential risk of new chemicals and wastewater effluents. Tests at the sub-cellular, individual, laboratory microcosm, and ecosystem levels are presented and critically evaluated. The influence of environmental and genetic heterogeneity on test standardization is also discussed. The book will be an excellent reference for industry professionals, consultants, regulatory officials, and students working in the ecotoxicology field.

Book Synopsis Ecological Risk Assessment by : Glenn W. Suter II
Download or read book Ecological Risk Assessment written by Glenn W. Suter II and published by CRC Press. This book was released on 1992-10-23 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
