"Heavy Metals: Problems and Solutions" is divided into three sections dealing with basic geochemical processes, remediation and case studies. The basic geochemical processes are discussed with respect to mobility in the environment and impact as well as methods to derive guidelines for heavy metals. Remediation focuses on currently available methods to treat contaminated sediments and soils. In addition, it considers the concept of geochemical engineering for remediation of large areas contaminated by metals. A number of case studies of polluted sediments and soils and their environmental impact highlight the principles discussed in the first two sections.

Most publications on heavy metals and the environment have focused on environmental pathways and risks. The present book establishes a link between the environmental risks of heavy metals and the societal causes of the risks. Economic models, substance flow models and environmental fate and risk assessment models have been integrated into a single analytical framework that has been used to trace and understand the routes by which four heavy metals enter the economy, through to their final destination in the environment. The long-term impacts of the current metals management regime in the Netherlands have been used as a case study by which to assess the effectiveness of certain policy measures. Readership: Environmental scientists, especially those practising in the areas of ecological economics, industrial ecology, materials flow accounting and integrated environmental assessment. Environmental policy makers will also find the book an invaluable aid in their deliberations.

This volume explores how the scientific tools of ecology can be used more effectively in dealing with a variety of complex environmental problems. Part I discusses the usefulness of such ecological knowledge as population dynamics and interactions, community ecology, life histories, and the impact of various materials and energy sources on the environment. Part II contains 13 original and instructive case studies pertaining to the biological side of environmental problems, which Nature described as "carefully chosen and extremely interesting."

Complexity, division, mistrust, and "process paralysis" can thwart leaders and others when they tackle local challenges. In Democracy as Problem Solving, Xavier de Souza Briggs shows how civic capacity -- the capacity to create and sustain smart collective action -- can be developed and used. In an era of sharp debate over the conditions under which democracy can develop while broadening participation and building community, Briggs argues that understanding and building civic capacity is crucial for strengthening governance and changing the state of the world in the process. More than managing a contest among interest groups or spurring deliberation to reframe issues, democracy can be what the public most desires: a recipe for significant progress on important problems. Briggs examines efforts in six cities, in the United States, Brazil, India, and South Africa, that face the millennial challenges of rapid urban growth, economic restructuring, and investing in the next generation. These challenges demand the engagement of government, business, and nongovernmental sectors. And the keys to progress include the ability to combine learning and bargaining continuously, forge multiple forms of accountability, and find ways to leverage the capacity of the grassroots and what Briggs terms the "grasstops," regardless of who initiates change or who participates over time. Civic capacity, Briggs shows, can -- and must -- be developed even in places that lack traditions of cooperative civic action.

Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children’s neurological development; to recommend a prevention strategy for protecting children’s health and development.
