Download or read book A Tentative Seven Day Test for Predicting Effects of Stress on Populations of Daphnia Pulex written by AL. Buikema and published by . This book was released on 1980 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both acute and chronic effects of water-soluble fractions of several hydrocarbon compounds and a simulated refinery effluent (SRE) were evaluated under laboratory conditions. The 48-h LC50 values (as percent water-soluble fractions) for creosote, No. 2 fuel oil, naphthalene, and phenanthrene were 2.9, 34.1, 57.5, and 100 percent, respectively. For the SRE, the 48-h LC50 was 0.03 times the formulation. For all the chronic studies, young Daphnia were exposed to sublethal concentrations corresponding to the calculated LC20 and LC30 values. Of the seven biological parameters measured, each compound had its greatest effect on the growth rate and number of live young produced. The effects of creosote and phenanthrene were the most dramatic.

Download or read book Biological Monitoring in Water Pollution written by John E. Cairns and published by Elsevier. This book was released on 2017-05-03 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Monitoring in Water Pollution focuses on the processes, methodologies, and experiments involved in monitoring water pollution. Divided into six parts, the selection features the contributions of authors who have devoted time and energy in advancing biological monitoring to measure pollution in water. The first part is a review paper that focuses on the strengths of biological monitoring relative to the detection of harmful conditions. This part stresses that biological monitoring has received considerable attention. The second part deals with review papers on biological monitoring. The discussions focused on the identification of problem; the review of functional methods; community and ecosystem indices used in biomonitoring; and structure and function relationships relative to ecosystem stress. The third part covers the application of community structural analysis to biomonitoring programs. This part puts emphasis on the need to develop methods to identify community structures relative to the conduct of ecological research. Other parts of the selection are devoted to toxicity testing and discussions on the monitoring of waste discharges and introduction of chemicals to the environment. Experiments and models are presented to support the claims of the authors. The book can be a valuable source of information for those interested in the monitoring of water pollution.

Download or read book Ecotoxicology Essentials written by Donald W. Sparling and published by Academic Press. This book was released on 2016-04-18 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology Essentials: Environmental Contaminants and Their Biological Effects on Animals and Plants provides a fundamental understanding of this area for students and professionals in ecotoxicology, ecology, conservation, chemistry, public health, wildlife management, fisheries, and many other disciplines. Although new chemicals and potential problems are developed every year, a basic education is essential to address these new challenges, and this work gives such training. Written with the regulatory framework in mind, the material guides readers on modelling, how to conduct assessments, and human and wildlife risk, focusing on effects on animals rather than transport of chemicals. Simple discussions of chemistry are complemented by coverage on the behavior of the animal, dynamics of the ecosystem, real-life situations like drought, and predators in the system – i.e., the natural system versus the lab setting. The book’s first section contains chapters on the principles of contaminant toxicology including a brief history of the science of ecotoxicology, basic principles of the science, testing methods, and ways of determining if animals have been exposed to either acute or chronic concentrations of contaminants. The second section deals with the primary classes of contaminants including their chemical characteristics, sources, uses, and effects on organisms. The third section focuses on more complex issues such as the regulation of pollution, population and community effects, risk assessment and modelling. Uses examples from both aquatic and terrestrial environments and species Includes a Terms to Know section and a list of study questions in each chapter, fostering a greater understanding of the issues Focuses on the effects of contaminants on wildlife while providing enough chemistry to allow a detailed understanding of the various contaminant groups Emphasizes natural examples and 'real' species, rather than laboratory studies on only a handful of organisms Features case histories, detailing actual events that include aspects of how the contamination occurred and its effects on wildlife Provides material from a wide variety of international sources

Available in PDF, EPUB and Kindle. Book excerpt: The volumes 3/I and 3/J present a modern account of polycyclic aromatic hydrocarbons (PAHs) and their heterocyclic analogs in the environment. The authors are internationally well recognized scientists belonging to those working presently in the frontline of the different subfields of this interdisciplinary area of environmental science; they give an integrated thorough overview on this hot topic. Extensive cross-referencing between chapters provides the readers with an easy access to all major areas. Due to the huge amount of material the text is published in two volumes (3/I and 3/J). It is expected that both volumes will soon become a major source of information and inspiration for all researchers actively working in PAH environmental chemistry or ecology.

Available in PDF, EPUB and Kindle. Book excerpt: ENVIRONMENTAL MANAGEMENT SERIES The current expansion of both public and scientific interest in environ mental issues has not been accompanied by a commensurate production of adequate books, and those which are available are widely variable in approach and depth. The Environmental Management Series has been established with a view to co-ordinating a series of volumes dealing with each topic within the field in some depth. It is hoped that this Series will provide a uniform and quality coverage and that, over a period of years, it will build up to form a library of reference books covering most of the major topics within this diverse field. It is envisaged that the books will be of single, or dual, authorship, or edited volumes as appropriate for respective topics. The level of presentation will be advanced, the books being aimed primarily at a research/consultancy readership. The coverage will include all aspects of environmental science and engineering pertinent to man agement and monitoring of the natural and man-modified environment, as well as topics dealing with the political, economic, legal and social con siderations pertaining to environmental management. J. CAIRNS and R.M. HARRISON v Preface The behaviour and effects of chemicals in our environment is a fascinating subject for scientific investigation. Furthermore, an understanding of these processes is of fundamental importance in our modern world, and should enable us to understand and limit the adverse effects of pollutants.

Available in PDF, EPUB and Kindle. Book excerpt: Hazard assessment of a compound (xenobiotic) discharged to the aquatic environment requires data on both exposure and effects to various components of the ecosystem. The multitude of ecological gradients in the Baltic Sea is used as a background example for discussing the complexity of the issue and the need for new approaches. Therefore, this book attempts to go beyond the simplistic, standardized short-term laboratory tests traditionally used as a basis for hazard assessment of chemicals, and gives strong emphasis to the interpretation of ecotoxicological data in their real, ecological context, pointing out the need to consider the natural mortality distribution of the population under study, the role of keystone species and of species with broad ecological niches versus those with narrow, specialized niches.
