Available in PDF, EPUB and Kindle. Book excerpt: The Chernobyl accident drew attention to the difficulties of understanding the dynamics of radionuclide transport through the environment using older methods developed after the pseudo steady state pollution resulting after the weapons testing fallout. More recent approaches, which are reported in this book, have incorporated both the dynamic aspects highlighted by the pulse Chernobyl input and the importance of improvement in models that can be brought about by constraining parameters on the basis of a knowledge of the fundamental physics, chemistry, biology and ecology of the ecosystems involved. The papers within this volume include hydrodynamic models of suspended solids transport, ion exchange interpretation of radionuclide sorption: approaches applying a knowledge of membrane transport kinetics to the uptake of radionuclides by biota; the effects of different ecological niches on the relative uptake of radionuclides by different species; kinetic models of radionuclide uptake through trophic chains and the success and failure of different countermeasures attempted after the Chernobyl accident.

Download or read book Fish Physiology Homeostasis and Toxicology of Essential Metals written by and published by Academic Press. This book was released on 2011-06-28 with total page 524 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

Download or read book Modelling radiocesium in lakes and coastal areas new approaches for ecosystem modellers written by Lars Håkanson and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last 10 years, there has been a `revolution' in ecosystem modelling. The generality and predictive power of our models have increased in a way that was inconceivable 10 years ago. This book describes a new generation of practically useful models that predict as well as one can measure - if one measures well. And yet, they are driven by readily available driving variables and have a general structure that applies to most types of pollutants in aquatic systems. The major reason for this development is, in fact, the Chernobyl accident. Large quantities of radiocesium were released in April/May 1986 as a pulse. To follow the pulse of radiocesium through ecosystem pathways has meant that important fluxes and mechanisms, i.e., ecosystem structures, have been revealed. It is important to stress that many of these new structures and equations are valid not just for radiocesium, but for most types of contaminants, e.g. for metals, nutrients and organics. This means that the models, methods (of building and testing models) and equations described in this book for lakes and coastal areas should be of great interest also to other ecosystem modellers. This book will be of considerable interest to: students in radioecology, geosciences and biology; environmental engineers; consultants; administrators and scientists interested in the spread, biouptake and ecosystem effects of chemical pollutants in aquatic ecosystems.

Download or read book Modelling Radioactivity in the Environment written by E.M. Scott and published by Elsevier. This book was released on 2003-05-22 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Just as an environmental model typically will be composed of a number of linked sub-models, representing physical, chemical or biological processes understood to varying degrees, this volume includes a series of linked chapters exemplifying the fundamental nature of environmental radioactivity models in all compartments of the environment. Why is a book on modelling environmental radioactivity necessary? There are many reasons why such a boook is necessary, perhaps the most important that: - modelling is an often misunderstood and maligned activity and this book can provide, to a broad audience, a greater understanding of modelling power but also some of the limitations. - modellers and experimentalists often do not understand and mistrust each other's work yet they are mutually dependent, in the sense that good experimental science can direct good modelling work and vice-versa; we hope that this book can dispel mistrust and engender improved understanding. - there is an increasing reliance on model results in environmental management, yet there is also often misuse and misrepresentation of these results. This book can help to bridge the gap between unrealistic expectations of model power and the realisation of what is possible, practicable and feasible in modelling of environmental radioactivity; and finally, - modelling tools, capacity and power have increased many-fold in a relatively short period of time. Much of this is due to the much-heralded computer revolution, but much is also due to better science. It is useful to consider what gap if any still remains between what is possible and what is necessary.
