Held in 1993 in Niterói, Brazil, the first International Conference on Environmental Geochemistry in Tropical Countries established a starting point for this book. The book opens with a discussion of the points that arose during the closing session, summarised by Dr. E.K. Duursma: The Environment in the Tropics Remains Unknown. Most of the processes that occur in temperate environments turn out to be completely different in the tropics. This can already be seen in Chapter 3, where estimates of radionuclide transfer factors reach values considerably greater than in temperate areas. The utilisation of variables measured in temperate environments for modelling of the tropics can result in completely erroneous conclusions and, worse, inefficient remediation solutions.

Hardbound. The use of exploration geochemistry has increased enormously in the last decade. The present volume specifically addresses those geochemical exploration practices appropriate for tropical, sub-tropical and adjacent areas - in environments ranging from rainforest to desert. Practical recommendations are made for the optimization of sampling, and analytical and interpretational procedures for exploration according to the particular nature of tropically weathered terrains. The underlying theme is the recognition that regions between 35N and 35S in particular have a common history of deep chemical weathering and lateritization during the late Mesozoic and early Tertiary. This has had a profound and lasting effect, so that the surface geochemical expressions of mineralization throughout these regions have many similar features, with local modification due to more recent weathering under changed climates.The volume discusses the da

Environmental and Low-Temperature Geochemistry presents conceptual and quantitative principles of geochemistry in order to foster understanding of natural processes at and near the earth’s surface, as well as anthropogenic impacts on the natural environment. It provides the reader with the essentials of concentration, speciation and reactivity of elements in soils, waters, sediments and air, drawing attention to both thermodynamic and kinetic controls. Specific features include: • An introductory chapter that reviews basic chemical principles applied to environmental and low-temperature geochemistry • Explanation and analysis of the importance of minerals in the environment • Principles of aqueous geochemistry • Organic compounds in the environment • The role of microbes in processes such as biomineralization, elemental speciation and reduction-oxidation reactions • Thorough coverage of the fundamentals of important geochemical cycles (C, N, P, S) • Atmospheric chemistry • Soil geochemistry • The roles of stable isotopes in environmental analysis • Radioactive and radiogenic isotopes as environmental tracers and environmental contaminants • Principles and examples of instrumental analysis in environmental geochemistry The text concludes with a case study of surface water and groundwater contamination that includes interactions and reactions of naturally-derived inorganic substances and introduced organic compounds (fuels and solvents), and illustrates the importance of interdisciplinary analysis in environmental geochemistry. Readership: Advanced undergraduate and graduate students studying environmental/low T geochemistry as part of an earth science, environmental science or related program.

At the International Earth Summit convened in Rio de Janeiro in 1994, all nations of the world were mandated to protect the environment for the benefit of present and future generations. This collection introduces the reader to the major issues involved in the management of a number of resources critical to Caribbean development. The chapters discuss the sustainability of water, fisheries and agriculture in the region from a variety of perspectives. Particular emphasis is also given to the use of energy, recreation and coastal resource management and their impact on the fragile ecosystem. The book makes a contribution to the ongoing debate of sustainable environmental management within the region and the world.

Phytoremediation is the process that uses plants to remove pollutants from soils. These pollutants are stored in the edible parts of plants and, if they are consumed above a certain level, they become a health risk for humans and animals. This book is a critical review of phytoremediation, its direct or indirect effects on food products, and the risks posed by this cost-effective technology in food safety. It shows how different plants are suited for phytoremediation, explains the role of toxicants in the environment, and analyses their effects and risks in the food chain at a global level. It also reviews the extraction methods of toxicants from plants after they are exposed to phytoremediation. Features: Summarizes the phytoremediation technology for effective remediation Describes different types of pollutants in soils that render food products useless Identifies the role of phytoremediation in the environment and its advantages and disadvantages Explains the role of phytoexclusion and phytostabilization in foods and food safety Includes many case studies to describe the extraction protocols in postharvest for food safety This book is intended for practitioners in public and private companies involved in soil remediation and food production, as well as graduate students and academics, in both developed and developing countries, who are involved in soil and environmental sciences, the food industry, agriculture, and biotechnology.

Geochemistry at the surface of the earth is dominated by two somewhat antagonistic forces: chemical reactions which attempt to attain a steady state (equilibrium) and geological movement of materials in time and space which changes the parameters that control chemical equilibrium. Another aspect that is extremely important to earth surface geochemistry is the effect of plants on the chemical and physical stability of materials (soils). Plant systems in fact work against the normal chemical changes (loss of silica, potassium, etc.) and the normal physical changes (stabilizing fine grained materials (clays) in the surface zones to avoid erosion). Biological effects are clearly seen in redox effects in the various parts of the earth surface movement cycle; soil formation, stream transport, sedimentation. This book attempts to outline these different parameters and their interactions as they affect earth surface geochemistry in order to give a better understanding of movement and accumulation of elements at the surface of the earth.

Recent critiques of air quality management approaches currently employed in developed and many developing countries have suggested that efficiencies could be achieved if air quality management practices shifted from pollutant-by-pollutant approaches to a comprehensive multipollutant approach in which emission reduction decisions are based on relative risk and evaluated on their effectiveness in meeting environmental and health goals. This book assesses our technical readiness to undertake such an approach, and it outlines the technical developments that will be needed to achieve a risk-based approach air quality management that includes means for measuring the effectiveness of management decisions.
