Book Synopsis The Sublethal Effects of Cu Exposure on the Osmoregulatory and Swimming Performance in Juvenile Rainbow Trout (Oncorhynchus Mykiss) by : Sydney Alexandra Sherwood Love
Download or read book The Sublethal Effects of Cu Exposure on the Osmoregulatory and Swimming Performance in Juvenile Rainbow Trout (Oncorhynchus Mykiss) written by Sydney Alexandra Sherwood Love and published by . This book was released on 2016 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cu is a widely occurring contaminant in aquatic systems and is acutely toxic to fish. The current paradigm of copper's toxic mechanism of action in fish is believed to be through direct effects on several important functions of the teleost gill; therefore experiments were conducted to examine Cu effects on the osmoregulatory ability and swimming performance of juvenile rainbow trout (Oncorhynchus mykiss) in water of varying hardness. Fish were exposed to three Cu concentrations (0, 20 and 60 μg/L in hard water [100 mg/L CaCO3], and 0, 6 and 16 μg/L in soft water [6 mg/L CaCO3]), for 4, 8 and 16 d and then tested for their ability to osmoregulate and burst swim. Burst swimming speed (Uburst) was not different between control and Cu-exposed fish in either soft or hard water. Osmoregulatory ability following Cu exposure was examined through several biochemical measurements related to osmoregulation and a seawater challenge. Cu exposure did not elicit a change in any osmoregulatory-related measurement or result in mortalities during the seawater challenge. These results indicate that the current paradigm of Cu toxicity may not reflect the mechanism of sublethal Cu toxicity or that compensatory mechanisms are offsetting major physiological disturbances caused by Cu, at concentrations that are near those which typically cause mortality in salmonids.

Book Synopsis Suitability of a Biochemical Method for Assessing the Exposure of Feral Fish to Lead by : BR. Blunt
Download or read book Suitability of a Biochemical Method for Assessing the Exposure of Feral Fish to Lead written by BR. Blunt and published by . This book was released on 1983 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of biochemical techniques have been used to assess the response of fish to contaminants. These techniques may provide valuable tools for determining the degree of impact on real fish populations of contaminant exposure and for identifying areas of contamination. Many of these techniques have not proven useful because they were not sensible, sensitive, or specific. This paper reviews the use of erythrocyte ?-amino levulinic acid dehydratase (ALAD) activity to indicate lead exposure of fish, both in the laboratory and in field surveys of Great Lakes fish. The enzyme has proven to be a reliable tool in laboratory studies of lead effects on rainbow trout (Salmo gairdneri). The field survey demonstrated that ALAD activity is a suitable indicator of lead exposure of lake trout (Salvelinus namaycush) but that more research is required to confirm its applicability to other species.
Book Synopsis Fish Physiology: Homeostasis and Toxicology of Essential Metals by :
Download or read book Fish Physiology: Homeostasis and Toxicology of Essential Metals written by and published by Academic Press. This book was released on 2011-08-11 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homeostasis and Toxicology of Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses. The companion volume, Homeostasis and Toxicology of Non-Essential Metals, Volume 31B, covers metals that have no known nutritive function in fish at present, but which are toxic at fairly low levels, such as Ag, Al, Cd, Pb, Hg, As, Sr, and U. In addition, three chapters in Volumes 31A and 31B on Basic Principles (Chapter 1, 31A), Field Studies and Ecological Integration (Chapter 9, 31A) and Modeling the Physiology and Toxicology of Metals (Chapter 9, 31B) act as integrative summaries and make these two volumes a vital set for readers. All major essential metals of interest are covered in metal-specific chapters Each metal-specific chapter is written by fish physiologists/toxicologists who are recognized authorities for that metal A common format is featured throughout this two volume edition
Book Synopsis Sediment Quality Assessment by : Graeme Batley
Download or read book Sediment Quality Assessment written by Graeme Batley and published by CSIRO PUBLISHING. This book was released on 2016-02-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.

Book Synopsis Mineral Tolerance of Animals by : National Research Council
Download or read book Mineral Tolerance of Animals written by National Research Council and published by National Academies Press. This book was released on 2006-01-22 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess minerals in the diet and water of animals can have an adverse effect on animal health, consumers, and the environment. Preventing unsafe mineral exposure is a fundamental part of animal nutrition and management. At the request of the Food and Drug Administration, the National Academies convened a committee to make recommendations on animal tolerances and toxic dietary levels, updating a 1980 report on mineral tolerance in domestic animals. Based on a review of current scientific data and information, the report sets a "maximum tolerable level" (MTL) for each mineral as it applies to the diets of farm animals, poultry, and fish. The report includes an analysis of the effects of toxic levels in animal diets, and it identifies elements that pose potential human health concerns. The report recommends research that includes a better characterization of animal exposure to minerals through feedstuffs; a better understanding of the relationship between mineral concentrations in feed and water and the levels in consumer products such as meat, milk, and eggs; and more research on the maximum tolerable level of minerals for aquatic and companion animals.
