Book Synopsis A Guide to the Canadian Wildlife Service National Registry of Toxic Chemical Residues by : John E. Elliott
Download or read book A Guide to the Canadian Wildlife Service National Registry of Toxic Chemical Residues written by John E. Elliott and published by . This book was released on 1987 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The computerized National Registry of Toxic Chemical Residues is a repository for information on wildlife specimens analyzed for toxic chemicals by the Canadian wildlife Service (CWS), or deposited in the CWS National Specimen Bank. Since 1963, residue data for more than 30, 000 individual specimens representing 327 species of Canadian wildlife have been added to the data base. Specimens were collected mainly from Canadian territories or near boundary U.S. territories, especially in the Great Lakes. There are also limited data from Canadian migratory species and their prey collected in Central and South America. The registry contains data only from specimens collected in the field and not experimentally dosed. This "User Guide" should help interested persons understand the registry system and assist the user in obtaining both data on residue levels in wildlife and information on the contents of the CWS National Specimen Bank"--Abstract, p. iv.
Book Synopsis Wildlife Ecotoxicology by : John E. Elliott
Download or read book Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

Book Synopsis Environmental Specimen Banking and Monitoring as Related to Banking by : R.A. Lewis

This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a great dispar.ity between the ability of the major industrial nations to produce and distribute chemicals and our ability to comprehend the nature and potential severity of unintended consequences for man, his life support systems and the environment generally. Furthermore, the gap between our ability to produce and distribute myriad chemicals and our ability to identify, understand or predict unfavorable environmental impacts may widen. As environmental scientists we are conscious of the interrelatedness, not only of environmental systems, but of nations as well. Materials are continually moved across boundaries by human as well as natural agencies. The extent, rate and nature of transfer for most pollutants is largely unknown. We can only guess which of the numerous chemicals produced are candidates for concern. More important still is our practical ignorance of the mechanisms of chronic effects upon natural systems and of the concentrations, combinations and circumstances that may lead to irreversibilities or to serious consequences for man. We know very little also regarding the potential for or the kinds of indirect effects that might occur. With respect to the environmentltself, we know little of its assimilative capacity with regard to widely dispersed pollutants and their transformation products. But what we do know is disquieting, and a much-improved system for the evaluation and management of toxic and hazardous chemicals is needed.
Book Synopsis Element Analysis of Biological Samples by : G. Venkatesh Iyengar
Download or read book Element Analysis of Biological Samples written by G. Venkatesh Iyengar and published by CRC Press. This book was released on 2020-11-25 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the development of innovative new analytical techniques for biological trace element research, today's trace element investigators face formidable obstacles to obtaining reliable data. This complete reference identifies and assesses the challenges the analyst encounters at each stage of an analysis, and discusses the effects of various techniques on the sample. Three internationally recognized scientists and authors consider the effects of the numerous collection, storage, and sample preparatory techniques used in sample analysis. Proper analytical quality control, including such critical factors as sampling and sample preparation, specimen preservation and storage, and ashing, is examined. The book also looks at sample preparation methods unique to various instruments and speciation chemistry issues, and examines the link between chemical analysis and specimen banking. A previously unrecognized source of error, presampling factors, is also discussed.

Book Synopsis Trends in Levels and Effects of Persistent Toxic Substances in the Great Lakes by : Michael Gilbertson
Download or read book Trends in Levels and Effects of Persistent Toxic Substances in the Great Lakes written by Michael Gilbertson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: `Are the Great Lakes getting better or worse?' This is the question that the public, scientists and managers are asking the International Joint Commission after a quarter-century of cooperative action by the United States and Canadian governments to clean up the Great Lakes. This volume contains papers from the workshop on Environmental Results, hosted in Windsor, Ontario, by the Great Lakes Science Advisory Board of the International Joint Commission, on September 12 and 13, 1996. The Great Lakes have been through almost a century of severe pollution from the manufacture, use and disposal of chemicals. In the 1960s wildlife biologists started to investigate the outbreaks of reproductive failure in fish-eating birds and ranch mink and to link these to exposure to organochlorine compounds. Human health researchers in the 1980s and 1990s linked growth retardation, behavioral anomalies and deficits in cognitive development with maternal consumption of Great Lakes fish prior to pregnancy. The Great Lakes became the laboratory where the theory of endocrine disruptors was first formulated. Now a group of Great Lakes scientists, hosted by the International Joint Commission, has compiled the story of the trends in the concentrations and effects of persistent toxic substances on wildlife and humans. The technical papers review the suitability of various organisms as indicators, and present the results of long-term monitoring of the concentrations and of the incidence of effects. The evidence shows that there was an enormous improvement in the late 1970s, but that in the late 1990s there are still concentrations of some persistent toxic substances that have stubbornly remained at levels that continue to cause toxicological effects.
