On a global basis, or among different metals, there is certainly no level playing field. The international journals Aquatic Toxicology and Environmental Toxicology and Chemistry were founded just 30 years ago, in 1981 and 1982, respectively. Furthermore, the fact that dying fish were suffering from both respiratory and ionoregulatory distress led to the discovery of the two main mechanisms of acute Al toxicity see Wilson, Chapter 2, Vol. Please be aware that the delivery time frame may vary according to the area of delivery and due to various reasons, the delivery may take longer than the original estimated timeframe. These include sources of metals, their economic importance, environmental situations of concern, essentiality or non-essentiality, bioconcentration or lack thereof, and the overarching importance of chemical speciation in understanding their effects on fish. In addition to the core focus, each chapter includes a brief summary of geochemical speciation, environmental concentrations in natural and polluted areas, environmental quality criteria from different countries, uses, and arguments for and against essentiality.
A few others, including Se and As, are honorary metals metalloids , sharing some but not all properties of true metals. Shipping: Item will be shipped through Canada Post the next business day upon payment is received. I would rate the book condition as 9. The other chapters of these two volumes illustrate many comparable situations. Not only did these researchers sacrifice nights, weekends, and holidays to craft their chapters, they also constructively reviewed many of the other chapters.
Furthermore, the chapters should help guide future research by pointing out significant data gaps for particular metals. Characterization of Excretion Routes 11. 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. Dividing estimated cumulative production by population is another way of putting these data into perspective; note the large increases in the cumulative metal burden per capita, despite the greater than four-fold increase in world population from 1900 to 2000 Fig. Sometimes not all items in your order are available for shipment at the same time, and items may be delivered separately. The mechanistic explanations are explored in the metal-specific chapters, and include direct protection by the competition of Ca²+ and Mg²+ with cationic metals for binding and uptake sites on organisms Section 3 , stabilization of tight junctions and membrane integrity of the gills by these ions Hunn, 1985 , and natural covariation with hardness of other protective features of water chemistry such as complexing agents, e. The chapters and volumes are constructed with a parallel structure that helps comparisons across the different metals.
The terms heavy metal universally viewed in a negative light by the general public and light metal often positively viewed are outdated and chemically meaningless Duffus, 2002; Hodson, 2004. Regardless, the two volumes are fully integrated by cross-referencing between the various chapters, and they share a common index. 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. Please Note: Deliveries of items with this status cannot be tracked. The publisher lists them as the First Edition. The computer on which this manuscript was typed contains 30—40 different metals. 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.
The careful reader will notice a heterogeneity among chapters in these summaries, which reflects both the present situation and the difficulty in obtaining exact information. 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. 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. These 2 volumes are likely to stand for some time as the defining compendium on the homeostasis and toxicology of metals in fish. All parcels are priced by the weight and destination. The most interesting and as yet poorly studied aspects of metal speciation occur in the brackish waters of estuaries, locations where metals are often discharged by sewage treatment plants and industries. Tony has received a number of awards for his scientific contributions: an honorary degree from the University of Gothenburg in Sweden; Awards of Excellence from the American Fisheries Society for Fish Physiology, Conservation and Management; the Fry Medal from the Canadian Society of Zoologists; and the Beverton Medal from the Fisheries Society of the British Isles.
In addition to the core focus, each chapter includes a brief summary of geochemical speciation, environmental concentrations in natural and polluted areas, environmental quality criteria from different countries, uses, and arguments for and against essentiality. Finally, a very practical consideration is that most aquatic metals research is funded by the industries that discharge or market the specific metals, or by their research associations, or by government agencies interested in improving environmental regulations. 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. This enlightened approach is where the level of protection is geared to the use and value of an ecosystem. The rationale is that hardness appears to be generally protective for most metals; Fe Bury et al.
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. The chapters and volumes are constructed with a parallel structure that helps comparisons across the different metals. Condition: Brand New, Product Type: Textbook, Format: Hardcover, Publication Year: 2011, Language: English See More. This will contain your All our estimates are based on business days and assume that shipping and delivery don't occur on holidays and weekends. Metals such as Ag, Al, Cd, Pb, Hg, As, Sr, and U have no known nutritive function in fish at present, but are toxic at fairly low levels. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr.
Please note that if the delivery address is incorrect and the order has been shipped, depending on the delivery option selected we may not be able to change the delivery address until the order has been returned. One notable exception is Pb only 2—3× , a metal that was heavily exploited in preindustrial times, and whose production in the latter part of the twentieth century was greatly curtailed owing to health concerns and efficient recycling. There are hundreds of similar examples in the literature for other metals. Randall A complete list of books in this series appears at the end of the volume Fish Physiology Homeostasis and Toxicology of Essential Metals Chris M. Indeed, we prefer to work at the interface of the two fields where physiological understanding of mechanisms explains toxic response, and toxicological phenomena illuminate physiological theory. No marks, highlights or such, still strong and tight. Chemical Speciation in Freshwater and Seawater 2.
Note that the largest increases are for Hg, mainly owing to prolific burning of coal in which it is a trace contaminant. The growth of such concern paralleled the growth of the environmental movement, catalyzed by the publication of Silent Spring by Rachel Carson 1962. A simple example will suffice. Na, Mg, K, Ca, Rb, Li, U, Al tend to bond ionically with oxygen donors, while soft class B metals e. The smallest increases are for Cr and Ni, for which exploitation only started in about 1950. Homeostasis and Toxicology of Non-Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years.
