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 707 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 The Eastern Screech Owl written by Frederick R. Gehlbach and published by Texas A&M University Press. This book was released on 2008 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eastern screech owl, widespread over the eastern half of North America and noticeably tolerant of human activity, is one of America's most familiar birds. Residing naturally in wooded environs with tree cavities, this owl lives well in suburbia and can be found nesting in mailboxes, porch columns, and purple martin houses. Based on a twenty-five-year study, biologist Frederick R. Gehlbach tells the life story of the eastern screech owl, focusing on case studies of suburban and rural study plots in Central Texas. This is the first thorough study of major life-history, behavioral, and ecological features of the species. Indeed, it is the first concurrent, comparative study of an urban and a rural population of any New World animal. Told in a personal voice, the story of these birds will interest all who have not lost touch with their ancestral world. However, Gehlbach has also included quantitative data and analysis of interest to ecologists, wildlife biologists, and ornithologists. Photographs (including color shots of the gray and rufous phases), figures, and tables provide further detail. Gehlbach's investigations have been those of not only an academic ecologist, but a suburbanite curious about his natural surroundings. The result is a model of research on species population dynamics and adaptation, yielding an emerging picture of what the eastern screech owl needs for successful coexistence with human neighbors.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Contamination of the environment by cadmium, a relatively rare heavy metal, is increasing and is especially severe in the vicinity of smelters and urban industrialized areas. Very low concentrations of cadmium have been implicated as the cause of numerous deleterious effects to fish and wildlife, especially aquatic life. This report briefly reviews ecological and toxicological aspects of cadmium, with emphasis on natural resources, and provides recommendations for the protection of sensitive species of wildlife and aquatic biota. Subtopics include: enviornmental chemiatry; background concentrations in terrestrial and aquatic organisms; toxic and sublethal effects, including bioaccumulation; and teratogenic, mutagenic, and carcinogenic properties. parag Keywords: contaminants; natural resources; toxicity; fishes; wildlife; cadmium; heavy metals; metabolism; sublethal effects

Download or read book Ecotoxicology of Soil Organisms written by Herman Eijsackers and published by CRC Press. This book was released on 1993-12-09 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive examination of all aspects of the ecotoxicology of soil organisms. The book explains how contaminants reach the soil, traces their transport through the soil, and then moves on to examine the effects of contaminants on different groups of soil organisms (e.g., microorganisms, micro- and mesofauna, larger soil animals including vertebrates). The book also considers food chain transfer and discusses risk assessment procedures that are specific to soil conditions. Ecotoxicology of Soil Organisms is the only book to take such a sweeping approach toward soil ecotoxicology.

Available in PDF, EPUB and Kindle. Book excerpt: Trace Elements in Human Health and Disease is a collection of papers presented at an international symposium on trace elements held in Detroit, Michigan on July 10-12, 1974. The symposium provided a forum for discussing the role of essential and toxic elements in human health and disease. These two volumes bring together a vast amount of information on trace elements zinc and copper, magnesium, selenium, fluoride, cadmium, lead, and mercury. They will be of great value to physicians, nutritionists, and toxicologists. A particularly interesting section relates to the leaching of important trace metals by excess dietary fiber in some developing countries. These books are one of the important monograph series published by the American Nutrition Foundation.

This book was released on 1999-11-24 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report examines seven disposal technologies being considered by the U.S. government as alternative methods to the process of incineration for destroying mortars, rockets, land mines, and other weapons that contain chemical warfare agents, such as mustard gas. These weapons are considered especially dangerous because they contain both chemical warfare agent and explosive materials in an assembled package that must be disassembled for destruction. The study identifies the strengths and weaknesses and advantages and disadvantages of each technology and assesses their potential for full-scale implementation.
