Download or read book Target Organ Toxicity in Marine and Freshwater Teleosts written by Daniel Schlenk and published by CRC Press. This book was released on 2003-09-02 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the numerous gaps in current information, Target Organ Toxicology in Marine and Freshwater Teleosts is an essential resource for researchers and professionals in aquatic toxicology and environmental risk assessment. All the chapters are written by researchers who are internationally recognised for their work in mechanistic aspects of aquatic toxicology. Each chapter focuses on a specific target organ or physiological system and describes how various agents disrupt the normal physiological system and processes. This volume is devoted to specific organs with coverage of the gill, kidney, skin, liver and gut. The companion volume, Systems, provides coverage of toxic effects in the central nervous, immune, neurobehavioural and reproductive systems as well as describing general mechanisms of toxicity.

Download or read book Biomonitoring of Trace Aquatic Contaminants written by David J.H. Phillips and published by Springer Science & Business Media. This book was released on 1994 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years ago, researchers wishing to identify contaminated areas in aquatic environments generally took water samples, and analysed them badly (as we have since discovered) for a few "pollutants" which were of topical note at the time (and which could be quantified by the methods then available). Today, the use of aquatic organisms as biomonitors in preference to water analysis has become commonplace, and many national and interna tional programmes exist around the world involving such studies. We believe that this trend will continue, and have complete faith in the methodology (when it is employed correctly). We hope that the following text assists in some part in attaining this goal, such that the quality of our most basic global resource -water - is adequately protected in the future. DAVE PHILLIPS, PHIL RAINBOW England, March 1992 vii Acknowledgements Our thanks for contributions to this book are due to several individuals and groups, for varying reasons. Firstly, a co-authored book is always a triumph, and we trust that the following text is an acceptable compromise of the views of two individual authors, on a complex and developing topic. Secondly, many of the ideas herein have crystallised over the last two decades as the field has grown, and we are individually and collectively grateful to a number of researchers for their insight and assistance.

Available in PDF, EPUB and Kindle. Book excerpt: During the twenty years the authors have been associated with the field of radiation ecology, there has been a diversified and increasing use of radionuclides in applied and basic biological research. Prior to the advent of the atomic age in the 1940s the use of radionuclides as tracers was initiated, and following that period one observed a dramatically increased use in many disciplines. Concurrent with this increase there appeared many books and articles on radionuclide tech niques useful to biologists in general. Although only a few ecological applications were evident in these early years, ecologists were quick to see the opportunities available in their field. In the United States, major centers for such activities included Oak Ridge National Laboratory and the U. S. Atomic Energy Com mission's Savannah River Plant. At Oak Ridge National Laboratory Dr. Stanley I. Auerbach, director of ecological activities, encouraged with remarkable suc cess the use of tracers by his associates. Dr. Eugene P. Odum had the foresight to see that radionuclide tracers provided the means to solve many problems of interest to ecologists. Consequently, his research included some unique radio tracer applications at the Savannah River Plant. In addition he encouraged others involved in ecological activities at the Savannah River Plant to do likewise. Ecologists such as Dr. Robert C. Pendleton at the U. S. Atomic Energy Com mission's Hanford Works applied radionuclides in their research. To these early investigators and to those who followed we owe the oppportunity to write this book.

This book was released on 1991-02-21 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has often been assumed by those studying animal behaviour that the social system adopted by a species is a fixed product of natural selection. There is now an interesting body of evidence that this is not always the case. In this book, first published in 1991, Professor Lott presents an overview of the understanding of this phenomenon.

Download or read book Boron written by C. Smallwood and published by . This book was released on 1998 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book evaluates the risks to human health and the environment posed by boron, a naturally occurring element widely distributed in the form of various inorganic borates in the oceans, sedimentary, rocks, coal, shale and some soils. Boron is also used in laundry bleach and in the manufacture of glass, glass products, fertilizers and herbicides, antiseptics, and pharmaceuticals. Since boron is widely detected in drinking-water and occurs naturally in fruits, nuts, and vegetables, the report gives particular attention to health risks associated with exposure of the general population through diet and drinking-water.A section on sources of human and environmental exposure cites evidence that boron enters the environment mainly through volatilization from seawater, volcanoes, geothermal steam, and natural weathering of clay-rich sedimentary rock. Although industrial uses account for much smaller releases, the report notes that all of the boron from the sodium perborate contained in detergents ultimately enters the wastewater system, and is not removed by standard water treatment procedures.
