Available in PDF, EPUB and Kindle. Book excerpt: Metal Poisoning in Fish provides a comprehensive look at many aspects of metal poisoning of euryhaline and stenohaline fish. Metals and metalloids are considered individually and collectively and include arsenic, lead, selenium, copper, cadmium, mercury, and zinc. This informative, readable volume is designed to help regulatory personnel, enforcement personnel, and scientists understand the impact of these elements on fish. Topics covered include mechanisms of action, toxicity, biological effects, accumulation, tissue distribution, concentration factors, maximum acceptable toxicant concentrations, application factors, biological half-lives, uptake kinetics, depuration kinetics, elemental speciation, and detoxification mechanisms. The book emphasizes the use of data gathered from a variety of sources to pinpoint specific elemental agents as causal factors in the morbidity and mortality of fish.

Download or read book Health Effects of Metals and Related Substances in Drinking Water written by Dr. Marco Ferrante and published by IWA Publishing. This book was released on 2013-11-15 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals are inorganic substances that occur naturally in geological formations. Naturally occurring metals are dissolved in water when it comes into contact with rock or soil material. Some metals are essential for life and are naturally available in our food and water. Trace amounts of metals are common in water, and these are normally not harmful to your health. In fact, some metals are essential to sustain life. Calcium, magnesium, potassium, and sodium must be present for normal body functions. Cobalt, copper, iron, manganese, molybdenum, selenium, and zinc are needed. However many of the metals and metalloids that are found in drinking water can have an adverse impact on human health. This book provides a 'state-of-the-art' review of the health implications of metals and metalloids in drinking water and is a key reference in the risk assessment and management of water supplies. The increased urbanization and increased water demand in industrial areas has amplified the metals problem in groundwater sources. In fact the contamination of our water resources by poisonous metals occurs largely due to human activity. These activities include industrial processes, such as electronics industry and mining activity, agricultural activities, and the dumping of wastes in landfills. The International standard references concerning water resources are various and, though they are based on WHO guidelines, they are extremely diversified in relation to local issues and emerging problems. This report pulls the information together to provide an important reference source.

Download or read book Quantitative Methods in Aquatic Ecotoxicology written by Michael C. Newman and published by CRC Press. This book was released on 1994-12-21 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a quantitative treatment of the science of ecotoxicology. The first chapters consider fundamental concepts and definitions essential to understanding the fate and effects of toxicants at various levels of ecological organization as covered in the remaining chapters. Scientific ecotoxicology and associated topics are defined. The historical perspective, rationale, and characteristics are outlined for the strong inferential and quantitative approach advocated in this book. The general measurement process is discussed, and methodologies for defining and controlling variance, which could otherwise exclude valid conclusions regarding ecotoxicological endeavors, are considered. Ecotoxicological concepts at increasing levels of ecological organization are discussed in the second part of the book. Quantitative methods used to measure toxicant effects are outlined in this section. The final chapter summarizes the book with a brief discussion of ecotoxicological assessment. Numerous figures and tables accompany text, with many statistical tables found in the appendix for quick reference. Although the book primarily focuses on aquatic systems, with appropriate modification the concepts and methods can be applied to terrestrial systems.

Book excerpt: Following up on his popular Techniques in Aquatic Toxicology with a second volume, now nine years later, Dr. Ostrander has once again called on the top aquatic toxicologists from across the world to present 39 chapters of unique collection and testing procedures. Updating five techniques from the first volume, the authors have gone on to add over two dozen new techniques. Every chapter covers a specific procedure that can easily be reproduced by any competent technician with basic knowledge. Each of the chapter authors provides and interprets typical and anomalous results, false positives, and artifacts. Data is provided either from recently published experiments or from work being published for the first time.

Download or read book Pollution Threat of Heavy Metals in Aquatic Environments written by G. Mance and published by Springer. This book was released on 2011-10-05 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of the European Community in developing environmental legislation has focused the minds of pollution control agencies and industrialists on the need for, and the evidence to support, water quality standards. This is particularly so for the Dangerous Substances Directive which has led to European standards for cadmium, mercury and lindane. Additionally the United Kingdom has published standards for six other non-ferrous metals. In this book I have sought to review the aquatic toxicity information for these and other metals, not just by the collation of the results of all the published toxicity tests, but by the critical consideration of the test techniques. A surprising proportion of the reported toxicity studies for aquatic organisms are based on unsatisfactory chemical or biological methods. That such weaknesses persist at a time of limited resources for environmental research is disappointing, especially when sound metho dologies are extensively documented and widely published. Evaluation of the critically reviewed and vetted data indicates that many of the previously accepted generalisations about the toxicity of metals to aquatic life are invalid: for instance the assumption that salmonid species of fish are more susceptible to these metals than coarse fish, or that increased water hardness decreases toxicity. Too few studies have actually sought to test such hypotheses.

This book was released on 2020-10-27 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy metal and metalloid contamination of groundwater and surface water ecosystems involves important policy-related and ethical issues besides its more well-known scientific aspects. Heavy Metal and Metalloid Contamination of Surface and Underground Water: Environmental, Policy, and Ethical Issues has brought these three dimensions under a single volume. The book presents an updated status of the nature and extent of heavy metal and metalloid contamination of water and discuss its future implications. In Section I, the book provides a state-of-the-art review of research findings on entry, storage, and release, human health risks, and the uptake and accumulation by freshwater biota and the toxic effects experienced by them. The book also provides information on the bioremediation of heavy metals and metalloids, and the possible effects of climate change on their distribution and toxicity. Section II of the book throws light on the policies and legislations adopted in several countries to deal with the vexed issue of metal contamination of waters in both historical and current perspectives. Special emphasis has been given to the contamination of drinking water and its attendant implications for human health. The book also treats the relevance and applications of Integrated Water Resources Management (IWRM), which forms the backbone of the water policies of several countries. In Section III, discussions focus on ethical issues rising out of heavy metal and metalloid contamination of water, and on the different ethical approaches and principles in both indigenous and other societies. Features: A systematic overview of the major facets of heavy metal and metalloid contamination of water Compilation and analysis of the latest research in the subject area Ample case studies in all chapters that highlight specific problems Review of policy and legislation for the control of heavy metal pollution of water Water ethics in indigenous societies This book will be a vital resource for students and research scholars in the field of environmental science, ecotoxicology, and pollution studies.
