This study has developed a complete procedure for the measurement of oxygen isotopes in arsenic oxyanions in natural waters by using different adsorbents. The experimental results of kinetic exchange of oxygen between AsO43- and water show that the entire exchange procedure happens in a very short time at different pH conditions and temperatures.

Immigrants and Foreigners in Central and Eastern Europe during the Twentieth Century challenges widespread conceptions of Central and Eastern European countries as merely countries of origin. It sheds light on their experience of immigration and the establishment of refugee regimes at different stages in the history of the region. The book brings together a variety of case studies on Poland, Hungary, Czechoslovakia, and Yugoslavia, and the experiences of return migrants from the United States, displaced Hungarian Jews, desperate German social democrats, resettled Magyars, resourceful tourists, labour migrants, and Zionists. In doing so, it highlights and explores the variety of experience across different forms of immigration and discusses its broader social and political framework. Presenting the challenges within the history of immigration in Eastern Europe and considering both immigration to the region and emigration from it, Immigrants and Foreigners in Central and Eastern Europe during the Twentieth Century provides a new perspective on, and contribution to, this ongoing subject of debate.

Selenium (Se), being an essential nutrient and a toxin, enters the food chain mainly via plants. Selenium isotope signatures were proved to be an excellent redox tracer, making it a promising tool for the exploration of the Se cycle in plants. The analytical method is sensitive on organic samples and requires particular preparation methods, which were developed and validated in this study. Plant cultivation setups revealed the applicability of these methods to trace plant internal processes.

The aim of this study was to describe and quantify Se transfer at the interface between soil and plant. For this purpose, three Se reservoirs were defined: soil, soil solution and plant, represented by kaolinite or goethite, nutrient solution and rice. First, Se transfer from solution to plant and Se partitioning in the plant was studied; then adsorption-desorption processes of Se onto kaolinite and goethite were investigated. Finally, a mass balance of the combined experiment was modelled.

This book consolidates much of what is known about the geochemistry of arsenic and provides new information on relationships between high concentrations of arsenic in ground water and geochemical environments. The subject matter of this book ranges in scope from molecular-scale geochemical processes that affect the mobility of arsenic in ground water, to arsenic contaminated ground water at the national scale. Chapters were contributed by an international group of research scientists from a broad range of backgrounds.

The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use
