Abstract

The first purpose of this book is to provide a comprehensive review of the state of development of natural analogue studies with emphasis on those studies which are relevant to the following repository designs: Nagra (Switzerland) disposal concepts for high-level waste/low and intermediate-level waste; SKB (Sweden) disposal concepts for spent fuel/low and intermediate-level waste; and Nirex (UK) disposal concept for low and intermediate-level waste. The book's second aim is to discuss the expanding application of natural analogues for non-performance assessment purposes, especially their pot

Abstract

In recent years, radioactive contamination in the environment by uranium (U) and its daughters has caused increasing concerns globally. This book provides recent developments and comprehensive knowledge to the researchers and academicians who are working on uranium contaminated areas worldwide. This book covers topics ranging from the beginning of the nuclear age until today, including historical views and epidemiological studies. Modelling practices and evaluation of radiological and chemical impact of uranium on man and the environment are included. Also covered are analytical methods used for the determination of uranium in geo/bio environments. Some chapters explore factors which influence uranium speciation and in consequence plant uptake/translocation. Last but not least, several chapters provide approaches and practices for remediation of uranium contaminated areas.

Abstract

Medical mineralogy and geochemistry constitute an important field, yet little attention has been paid to it by scientists, administrators, or the public. The aims of this book are: (a) to focus on a selection of current challenges and research opportunities and (b) to encourage knowledge transfer between geochemists and mineralogists whose work concerns medical problems and medical scientists who study problems surrounding biominerals and geomaterials. This book covers a variety of novel approaches, tools and techniques, and scenarios of contamination in water and wastewater, and is a key resource for policymakers and environmental scientists working hard to address environmental pollutants. The key features are: state-of-the-art techniques for the assessment and remediation of heavy metals, presenting the interdisciplinary impacts of heavy metals, including those on human health, ecosystems and water quality, and including various contamination indices, such as contamination factor, geoaccumulation index, enrichment factor, pollution index and ecological risk index.

Abstract

The book compiles scientific articles describing advances in nanomaterial synthesis and their application in water remediation. The publications treat diverse problems such as dye degradation, heavy metal ion, as well as radioactive element capture and sequestration. There are 10 original research articles and one review article. The latter proposes graphene/CNT and Prussian blue nanocomposites for radioactive 137-cesium extraction from aqueous media. All reports thoroughly characterize the nanomaterials post-synthesis and describe their catalytic, photocatalytic, or ion exchange activities in contaminated water. The dyes studied in the collection are azo dyes, i.e. methylene blue and orange, rhodamine B, phenolic dyes viz. bromophenol blue, and other dyes with sulfonyl groups. Extraction of radioactive elements, including cationic 137Cs+ and anionic 125I?, is also investigated. The omnipresence of ZnO nanoparticles in everyday products and their effects in wastewater are also evaluated. Layered double hydroxide are capable of capturing Ag ions, which then has a catalytic effect on dye degradation. The nanomaterials considered are varied, viz., graphene, CNT, Prussian blue, nanoporous carbon, layered double hydroxides, magnetite, ferrites, organic powders, polymer membranes, bacteria, and inorganic nanomaterials such as MnO and Ag. The book targets an interdisciplinary readership.

Abstract

The book deals with various consequences of major nuclear accidents, such as in 1986 in Chernobyl and in 2011 in Fukushima. The public is extremely interested in learning more about the movements and risks posed by radiation in the environment related to food supply and food safety. Radionuclides are found in air, water, soil and even in us not only after nuclear accidents because they occur also in nature. Every day, we ingest and inhale radionuclides in our air and food and the water. This book provides a solid underpinning of the basic physical-chemistry and biogeochemistry of naturally occurring and anthrop radioactivity. The mechanisms of radioactive element transfer in the atmosphere, tropospheric and stratospheric diffusion of radioactivity, environmental contamination from accidents and the impact of atmospheric pollution on the food chain, soil and plants, are analyzed and the analytical methods are illustrated. The question of natural radioactivity concentration in building materials is addressed too. While the book contains many case studies and data for Greece, it is of general value. It contributes to the development of international environmentally safe standards and economically reasonable standard regulations based on justified radiological, social and economical legislation concepts.

Abstract

Many countries are currently exploring the option to dispose of highly radioactive solid wastes deep underground in purpose built, engineered repositories. A number of surface and shallow repositories for less radioactive wastes are already in operation. One of the challenges facing the nuclear industry is to demonstrate confidently that a repository will contain wastes for so long that any releases that might take place in the future will pose no significant health or environmental risk. One method for building confidence in the long-term future safety of a repository is to l

Abstract

Food Additives & Contaminants, Part A publishes original research papers and critical reviews covering analytical methodology, occurrence, persistence, safety evaluation, detoxification and regulatory control of natural and man-made additives and contaminants in the food and animal feed chain. Papers are published in the areas of pesticide and veterinary drug residues, environmental contaminants, natural toxicants, mycotoxins, trace elements, migration from food packaging, food processing contaminants, authenticity and allergenicity of foods. Papers are published on animal feeds where residues and contaminants can give rise to food safety concerns. Contributions cover chemistry, biochemistry and bioavailability of these substances, factors affecting levels during production, processing, packaging and storage; the development of novel foods and processes; exposure and risk assessment.
