The discussion on arsenic in the environment is complex and must grasp the importance of very many, mostly unrelated works on individual aspects. This volume represents one of the first comprehensive and interdisciplinary examinations into arsenic's behaviour in air, water, soils, sediments, plants and the human body. Based on state-of-the-art investigations into the global arsenic cycle, the related human toxicology and available remediation technologies, arsenic is assessed holistically in all the environmental compartments. Using the results of primary research, the authors offer concrete suggestions for risk reduction and management of environmental pollution that allow the reader to successfully tackle similar problems and find sustainable solutions. The book consists of three essential parts: Review of the current knowledge of arsenic behaviour in the environment (global biogeochemical cycles), toxicology, remediation techniques, immobilization technologies and environmental legislation Case studies for mining-related arsenic problems Discussion of mitigation and remediation technologies and approaches such as environmental education, hygiene training, backed by real experience and successful implementation in the study area In a highly coherent manner, the book makes use of 120 tables and figures, a large number of literature citations, and very detailed subject index (that encompasses references) to provide rapid and up-to-date access to all relevant information. Cross-references provide a great manoeuvrability between the chapters. The book delivers very insightful and hands-on approaches for graduate students and professionals working on arsenic questions not only in environmental science, but also in the fields of environmental engineering, medicine and social science.

Groundwater resources naturally contain rather high levels of arsenic in many parts of the world. During the last two decades, the As-containing groundwater in South-East Asia has received much attention. However, the situation seems to be equally important in Latin America, where the number of studies is still relatively low, and the extent and severity of As-exposure in the populations is only marginally evaluated. Following this lack, the book aims to improve the knowledge and understanding on the occurrence and genesis of As-rich groundwaters in Latin America. It deals with constraints on the mobility of As in groundwater, As-uptake from soil and water by plants, As-propagation through the food chain, human health impacts, and As-removal technologies. Case studies are presented from Argentina, Bolivia, Chile, Ecuador, El Salvador, Mexico, Nicaragua, Peru, and other Latin American countries, and are backed up by experiences from other world regions. is designed to: create interest within the Latin American countries affected by the presence of arseniferous aquifers, address the international scientific community, increase awareness among administrators, policy makers and company executives, and improve the international cooperation on that topic.

Naturliche Stoffkreislaufe weisen teilweise sehr komplizierte Ruckkopplungsmechanismen auf. Geochemie und "Umwelt" beschreibt solche Regelkreislaufe in der Atmosphare, der Pedosphare, der Anthroposphare und der Hydrosphare. Ein klares Konzept und die Konzentration auf wichtige und aktuelle Forschungsschwerpunkte kennzeichnen die Beitrage, die von fuhrenden Wissenschaftlern der Umweltgeochemie verfasst sind. Das Buch ist nicht nur Ausbildungsstandard fur Studenten und Hochschullehrer, sondern liefert auch Praktikern das aktuelle Wissen fur ihre Arbeit."
