This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its inherent characteristics, mercury contamination from gold mining is a major environmental problem compared to past mercury contamination from industrial point sources. The worsening of social-economical conditions and increasing gold prices in the late 1970s resulted in a new rush for gold by individual entrepreneurs for whom Hg amalgamation is a cheap and easily carried out operation. Even after the present-day mining areas are exhausted, the mercury left behind will remain part of the biochemical cycle of the tropical forest. This book reviews the current information on mercury from gold mining, its cycling in the environment and its long-term ecotoxicological impact. The book is illustrated with numerous diagrams and photographs.

This book was released on 2021-11-09 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue aims to provide new insights into the issue of the mercury contamination of terrestrial and aquatic ecosystems. This ubiquitous contaminant has been used by humans for many years, resulting in global contamination. When this toxic contaminant is converted to methylmercury, it accumulates in trophic chains, which is a major issue for wildlife and human health. The nine articles contained within this Special Issue on ''Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems'' endeavour to identify the historical evolution of Hg and MeHg levels in aquatic environments, and to evaluate the impact of current and historical human activities, such as mining, climate change, and soil erosion, on receptor ecosystems and food chains.

Available in PDF, EPUB and Kindle. Book excerpt: This is a wonderful book rich in empirical detail, full of theoretical insights, offering hope in a bleak world, altogether inspiring. . . a tremendous achievement of having helped to create the disciplines of ecological economics and political ecology, bringing them alive in this book, and making their insights available to the developing worldwide movement for environmental justice. Pat Devine, Environmental Values Any book by the ecological economist Joan Martinez-Alier is a Big Publishing Event. . . this is a book by a writer who loves his subject, knows it well, respects its history, and is driven by the desire to do justice. These are qualities enough to send you to the bookshop or the library in search of The Environmentalism of the Poor. Andrew Dobson, Environment Politics The book is a worthy and in-depth contribution to debates about political ecology and ecological economics. It should be read by all environmental and ecological economists who wish to make their analysis more relevant. Tim Forsyth, Progress in Development Studies A marvellous combination of insight, research and activism. . . A must-read for policymakers, practitioners and academics alike, and for anyone concerned with sustainable development, environmentalism or poverty alleviation. Human Ecology Journal . . . one of the most important environmental books to have been published recently. Martinez-Alier integrates two of the most significant areas of environmental theory political ecology and ecological economics. Eurig Scandrett, Friends of the Earth Scotland The book has three main strengths: its bibliography, which is extensive; the global perspective on the environmental movement and the relationship with poverty; and the general theme of this interdisciplinary work, which is not so much to provide new information, but to consider the existing information in a new light. Martinez-Alier is to be commended for taking such a step in the literature . . . the writing style is extremely approachable . . . Recommended. B.J. Peterson, Choice [Joan] Martinez-Alier combines the honest discipline of a scholar with the passionate energy of an activist. The result, The Environmentalism of the Poor, is highly recommended! Herman E. Daly, University of Maryland, College Park, US The Environmentalism of the Poor has the explicit intention of helping to establish two emerging fields of study political ecology and ecological economics whilst also investigating the relations between them. The book analyses several manifestations of the growing environmental justice movement , and also of popular environmentalism and the environmentalism of the poor , which will be seen in the coming decades as driving forces in the process to achieve an ecologically sustainable society. The author studies, in detail, many ecological distribution conflicts in history and at present, in urban and rural settings, showing how poor people often favour resource conservation. The environment is thus not so much a luxury of the rich as a necessity of the poor. It concludes with the fundamental questions: who has the right to impose a language of valuation and who has the power to simplify complexity? Joan Martinez-Alier combines the study of ecological conflicts and the study of environmental valuation in a totally original approach that will appeal to a wide cross-section of academics, ecologists and environmentalists.

Download or read book Toxicological Effects of Methylmercury written by National Research Council and published by National Academies Press. This book was released on 2000-09-27 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.

Download or read book Socioecological Transitions and Global Change written by Marina Fischer-Kowalski and published by Edward Elgar Publishing. This book was released on 2007 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'In an important contribution to sustainability science, Fischer-Kowalski and Haberl extend the frontiers of contemporary socio-ecological research to articulate a theory of material, energy and land-use transitions across multiple scales based on detailed empirical studies in Europe and Asia. The insights it presents on agrarian-industrial transitions are crucial to understand the potential impact of emerging nations like India and China on global change.' - Aromar Revi, India China Institute, The New School University, US 'This volume represents the culmination of several years of empirical research and refinement of the social metabolism approach. That approach is one of the most exciting and illuminating innovations in the fields of human ecology, industrial ecology, and environmental history. Here the team from Vienna's Institute of Social Ecology shows masterfully how the insights of social metabolism shed light on transitions to high-energy society in Austria, in Britain, and in the world at large.' - J.R. McNeill, Georgetown University, US This significant new book analyses fundamental changes in society-nature interaction: the socioeconomic use of materials, energy and land. The volume presents a number of case studies addressing transitions from an agrarian to an industrial socioecological regime, analysed within the materials and energy flow accounting (MEFA) framework. It is argued that by concentrating on the biophysical dimensions of change in the course of industrialization, social development issues can be explicitly linked to changes in the natural environment. From the historical transition in Europe, to current transitions in developing countries, the book offers a broad and comprehensive analysis of transition processes across scales, from local to national. The comparison of historical and current assessments allows a theory of the underlying patterns of the agrarian-industrial transition to emerge. On this basis, future trends and possible pathways towards (or indeed further departures from) sustainability are discussed. Empirical in character and cautious in its assumptions, this insightful book provides rich and in-depth material for further studies in socioecological research. It will be essential reading for students and researchers of ecological economics, industrial ecology, human ecology, environmental sociology, environmental history, geography as well as land, energy and development studies.
