Available in PDF, EPUB and Kindle. Book excerpt: "More than 5 million Canadians take part in recreational angling each year, spending over 50 million days fishing on open water. Recreational anglers contribute to environmental lead deposition through the loss of lead fishing sinkers and jigs. Each year, lost or discarded fishing sinkers and jigs amounting to an estimated 500 tonnes of lead, and representing up to 14% of all nonrecoverable lead releases in Canada, are deposited in the Canadian environment. Wildlife, primarily piscivorous birds and other waterbirds, ingest fishing sinkers and jigs during feeding, when they either mistake the sinkers and jigs for food items or grit or consume lost bait fish with the line and weight still attached."--from Abstract.

Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Download or read book Environmental Contaminants in Biota written by W. Nelson Beyer and published by CRC Press. This book was released on 2011-02-23 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examining tissue residues of contaminants in biota reveals the movement of contaminants within organisms and through food chains as well as the context for understanding and quantifying injuries to organisms and their communities. Yet tissue concentrations of some contaminants are especially challenging to interpret and the ability of today’s analytical chemists to provide reliable analytical data of most important environmental contaminants often surpasses the ability of ecotoxicologists to interpret those data. Offering guidance on the ecotoxicologically meaningful interpretation of tissue concentrations, Environmental Contaminants in Biota, Interpreting Tissue Concentrations, Second Edition is updated with current data and new ways of analyzing those data as well as additional contaminants not previously considered. Beginning with a history of wildlife toxicology and data interpretation, chapters cover a wide range of contaminants and their hazardous and lethal concentrations in various animals including DDT, Dioxins, PCBs, and PBDEs in aquatic organisms; methylmurcury, selenium, and trace metals in fishes and aquatic invertebrates; and pharmaceuticals and organic contaminants in marine mammals. The book considers the impact of Polychlorinated Biphenyls, Dibenzo-p-Dioxins and Dibenzofurans, and Polybrominated Diphenyl Ethers; cyclodiene; and other organochlorine pesticides in birds and mammals. Later chapters examine the effects and analysis of lead, cadmium, and radionuclides in biota. With thousands of published research papers reporting tissue concentrations each year, Environmental Contaminants in Biota, Interpreting Tissue Concentrations, Second Edition gives ecotoxicologists the ability to draw actionable value regarding the toxicological consequences of those concentrations and relate tissue concentrations quantitatively to injury: the core of ecotoxicology.

Download or read book Singing Wilderness written by Sigurd F. Olson and published by Knopf. This book was released on 2012-05-30 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: To do with the calling of loons, with northern lights, and the great silences of land lying northwest of Lake Superior. It is concerned with the simple joys, the timelessness and perspective found in a way of life which is close to the past. I have heard the singing in many places, but I seem to hear it best in the wilderness lake country of the Quetico-Superior, where travel is still by pack and canoe over the ancient trails of the Indians and voyageurs." Thus the author sets the theme and tone of this enthralling book of discovery about one of the few great primitive areas in our country which have withstood the pressures of civilization. Acute natural perceptivity and a profound knowledge of the relationships to be found in nature combine here in vivid evocations of the sights, the sounds, the vast stillnesses, and the events of the wilderness as the seasons succeed each other. But Mr. Olson is not content merely to "describe; he probes for meanings that will lead the reader to a different and more revealing way of looking at the out-of-doors and to a deeper sense of its eternal values. In each of the thirty-four chapters of The Singing Wilderness he has sought to capture an essential quality of our magnificent lake and forest heritage. He shows us what can be read from the rocks of the great Canadian Shield; he offers a delightful essay on the virtues of pine knots as fuel; he writes of the ways of a canoe, of flashing trout in the pools of the Isabella, of tamarack bogs, caribou moss, the flight of wild geese, timber wolves, and the birds of the ski trails. And much more, with something to satisfy every taste for wilderness experience. Superbly illustrated with 38 black-and-white drawings by Francis Lee Jaques, The Singing Wilderness is a book that no lover of nature will want to be without. To anyone who contemplates a vacation in the lake country of northern Minnesota and adjoining Canada, it is the perfect vade mecum.
