Download or read book Metal Poisoning in Fish written by Elsa M. B. Sorensen and published by CRC Press. This book was released on 1991-05-03 with total page 392 pages. 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 Environmental Contaminants in Fish written by Derek C. G. Muir and published by The Study. This book was released on 1996 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarises and interprets the analytical results for various organic chlorine contaminants in fish collected from northern Alberta river systems and also compares the observed organochlorine levels with the regulatory limits set by Health Canada. Major organochlorine groups detected were polychlorinated biphenyls, DDT- and chlordane-related compounds, toxaphene, and chlorinated phenolics. Background information is included on the properties, uses, toxicity, sources, environmental fate and transport, and bioaccumulation of the contaminants studied. Results are given for such fish species as mountain whitefish, burbot, northern pike, and longnose sucker, and for concentrations observed at locations downstream and upstream of known sources of contaminants.
Download or read book Contaminated Fish written by Patrizio Da Como and published by Nova Science Publishers. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results from the National Lake Fish Tissue Study indicate that mercury, PCBs, and dioxins and furans are widely distributed in lakes and reservoirs in the lower 48 states. These waterbodies occur in a variety of landscapes, and they can receive contaminants from several sources, including direct discharges in the water, air deposition and agricultural or urban runoff. Monitoring fish contamination in lakes and reservoirs is a critical activity for protecting human and ecosystem health because lakes and reservoirs provide important sports fisheries and other recreational opportunities. Lake ecosystems also provide critical habitat for aquatic species, and they support wildlife populations that depend on aquatic species for food. This book is a study of contaminants found in fish and their environmental impact.

Available in PDF, EPUB and Kindle. Book excerpt: Pollution, specifically heavy metal pollution, in various bodies of water has been a significant issue for decades. Research has been conducted on heavy metals and their effects on the environment, larger fish species, and humans since the 1970s (Skidmore, 1964; Adeniyi et al., 2007; Adeosun et al., 2015; Bawuro et al., 2018). It is known that zinc is a neurotoxin in some species and causes harm to the environment. It is also known that it causes harm to people if it is ingested or if they are exposed to it for long periods of time (Mahurpawar, 2015; Mizuno and Kawahara, 2013; Mohod & Dhote, 2013; Morris & Levenson, 2017) There is ample research on certain heavy metals and their effects on behaviors in commercially and scientifically important fish species, such as feeding and swimming. However, there is little research in other areas of behavior, such as learning, in fish species that are non-anthropocentrically important. One such species is Peter’s Elephantnose fish, Gnathonemus petersii. This research project aims to thoroughly review previous publications on the subject of heavy metals and their effect on various aspects of fish behavior and physiology and to assess the effects that zinc has on the learning abilities of weakly electric fish.
Download or read book Oil in the Sea III written by National Research Council and published by National Academies Press. This book was released on 2003-03-14 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
Download or read book Water Reuse written by Chris Binnie and published by IWA Publishing. This book was released on 2008-05-14 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differently wastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater. In the first section water reuse practices around the world are described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view. Each reuse purpose demands different water quality, not only to protect health and the environment but also to fulfil the requirements of the specific reuse. Reuses considered are agricultural, urban agriculture as a special case of the former, municipal and industrial. Alongside these uses, the indirect reuse for human consumption through aquifer recharge is also discussed. The third section deals with emerging and controversial topics. Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as the different international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered. The fourth section of the book presents contrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse. Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for human consumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for regulating water reuse in several countries, the Mediterranean situation is described. Other case studies presented refer to the reuse situation in Israel, Spain, Cameroon, Nepal and Vietnam, these latter countries being located in water rich areas. This book will be an invaluable information source for all those concerned with water reuse including water utility managers, wastewater policy makers and water resources planners as well as researchers and students in environmental engineering, water resources planning and sanitary engineering.
