This book was released on 1980 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population densities of the Asiatic clam, Corbicula fluminea, in the thermally influenced areas of the New River at the Glen Lyn power plant, Glen Lyn, Va., increased from zero before 1975 to approximately 11 522/m2 by February 1978. Since their establishment, clams in the thermal effluent have served as a source of propagules for clam invasion into other areas of the New River during the warmer seasons.

This book was released on 2012-12-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of the European Community in developing environmental legislation has focused the minds of pollution control agencies and industrialists on the need for, and the evidence to support, water quality standards. This is particularly so for the Dangerous Substances Directive which has led to European standards for cadmium, mercury and lindane. Additionally the United Kingdom has published standards for six other non-ferrous metals. In this book I have sought to review the aquatic toxicity information for these and other metals, not just by the collation of the results of all the published toxicity tests, but by the critical consideration of the test techniques. A surprising proportion of the reported toxicity studies for aquatic organisms are based on unsatisfactory chemical or biological methods. That such weaknesses persist at a time of limited resources for environmental research is disappointing, especially when sound metho dologies are extensively documented and widely published. Evaluation of the critically reviewed and vetted data indicates that many of the previously accepted generalisations about the toxicity of metals to aquatic life are invalid: for instance the assumption that salmonid species of fish are more susceptible to these metals than coarse fish, or that increased water hardness decreases toxicity. Too few studies have actually sought to test such hypotheses.

Download or read book Freshwater Bivalve Ecotoxicology written by Jerry L. Farris and published by CRC Press. This book was released on 2006-11-16 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Responding to the growing need for an aggressive yet conservative approach to evaluating mussel populations, Freshwater Bivalve Ecotoxicology provides a collective review of the techniques and approaches for assessing contaminant impact on freshwater ecosystems. The editors incorporate coverage of research topics and management issues from a cross-section of scientists in the field. They explore current advances in general monitoring of population responses to stressors, fundamental concepts of ecotoxicology specific to burrowing bivalves, and useful insights that offer direction and priority for resolving specific problems challenging protection and conservation efforts. This book lays the groundwork with discussions of topics such as impact assessment, toxicokinetics, biomarkers, and pollution tolerance. The authors then explore fundamental concepts surrounding responses measured in freshwater bivalves as a consequence of chemical exposures or accumulated contaminants in target organs or tissues. They highlight the difficulties encountered with the laboratory culture of these organisms for toxicity testing or other controlled experiments, and examine the use of surrogate test organisms to relate sensitivities of response and reduce pressure on already impacted fauna. The book also reviews innovative field research using in situ bivalve toxicity testing, discusses effects-oriented tissue contaminant assessment, and concludes with threefour specific laboratory or combined field/laboratory ecotoxicology studies. A summary of methods from more than 75 laboratory toxicity studies conducted with freshwater mussels, the book provides an overview of a standardized method for conducting water-only acute and chronic laboratory toxicity tests with glochidia juvenile freshwater mussels. It focuses on studies that report measured contaminant treatments, had robust experimental designs, including replication of control and contaminant treatments, and were published in the peer-reviewed literature. The resulting array of viewpoints provides a framework that can be used to establish priorities in the rehabilitation and management of freshwater ecosystems.
