Download or read book Polybrominated Diphenyl Ethers PDBEs and Polychlorinated Biphenyls PCBs in the Serum of Domestic Canines sentinels for Evaluating Environmental Pollutant Exposure written by Grace Christina Lau and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are human-made chemicals that are environmentally persistent and ubiquitous in nature due to their resistance to degradation and lipophilic nature. Since household dogs share the human environment, they may serve as biosentinels of human exposure to these contaminants. Serum samples were collected from client-owned dogs visiting the University of California Davis William R. Pritchard Veterinary Medical Teaching Hospital during 2012 to 2016 for routine appointments. The relationship between the concentrations of 14 PBDEs and 23 PCBs in serum of domestic canines diagnosed with hypothyroidism was investigated. Of the 51 dogs enrolled in this study, 15 dogs were diagnosed with hypothyroidism. The median concentrations of total PBDE and PCB in the hypothyroid group were 660 and 1371 ng/g lipid, respectively, which were higher than concentrations detected in the control group. However, logistic regression analysis determined that current concentrations of PBDEs and PCBs in canines were not associated with hypothyroidism diagnosis. BDE 183 was the only congener showing near significance (p = 0.068). PBDE and PCB congeners were detected in all canine samples confirming ongoing exposure to these pollutants. Because of the high metabolic capabilities of dogs, metabolism of PBDEs and PCBs via hydroxylation and dehalogenation may have resulted in formation of metabolites interfering with thyroid function. Since household dogs share the human environment, they may serve as biosentinels of human exposure to these contaminants.

This book was released on 2011-09-09 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Impacts of Toxic Chemicals presents a comprehensive, yet readable account of the known disturbances caused by all kinds of toxic chemicals on both aquatic and terrestrial ecosystems. Topics cover the sources of toxicants, their fate and distribution through the planet, their impacts on specific ecosystems, and their remediation by natural systems. Each chapter is written by well-known specialists in those areas, for the general public, students, and even scientists from outside this field. The book intends to raise awareness of the dangers of chemical pollution in a world dominated by industry and globalization of resources. Because the problems are widespread and far reaching, it is hoped that confronting the facts may prompt better management practices at industrial, agricultural and all levels of management, from local to governmental, so as to reduce the negative impacts of chemical contaminants on our planet.

Download or read book The Rasputin Effect When Commensals and Symbionts Become Parasitic written by Christon J. Hurst and published by Springer. This book was released on 2016-07-05 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.

Available in PDF, EPUB and Kindle. Book excerpt: The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.

This book was released on 2000-02-03 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.
