This volume entitled "Radionuclides and Heavy Metals in Environment" contains the Proceedings of the NATO Advanced Research Workshop (ARW) "Monitoring of Natural and Man-Made Radionuclides and Heavy Metal Waste in Environment" that was held at the Joint Institute for Nuclear Research (JlNR), Dubna, Russia from 3 October to 6 October, 2000. Originally, it was planned to held the ARW in 1999, the year when NATO was celebrating its 50th anniversary. Few days before opening it had to be postponed because of problems in issuing visa for all the colleagues who intended to participate. The ARW was organized and conducted by the co-directors Prof. Vladimir P. Perelygin, Joint Institute for Nuclear Research, Dubna, Russia and Dr. Peter Vater, Philipps Universitat, Marburg, Germany. The JlNR was chosen as the host institute of ARW because of the lack of contact and real co-operation between the former Soviet Union (FSU) countries specialists in ecology and their Western well experienced colleagues. The selection of this location and supplementary funds provided by Russian Foundation on Basic Research, Moscow, Russia, and the JINR, Dubna., Russia made it possible to attain a rather large number of participants and observers from FSU countries. The JlNR provided to all the participants of the workshop an effective car/minibus transportation Moscow-Dubna-Moscow and a rather good accommodation in Dubna.

This book examines the role that bioremediation can play in the detoxification of soil, water, and air to improve environmental and human health, with a specific focus on heavy metals and radionuclides. Environmental pollution, whether by natural or human causes, with industrial activities being a key player, is a challenge facing all nations across the world. While treatment has typically required the use of expensive technology, one promising solution is the use of phytoremediation, in which plants act by metabolizing or sequestering pollutants. This eco-friendly solution is a good alternative to the standard methods of soil and water treatments. This book provides not only the basic definitions and classification of technologies used for contaminant remediation but also the most recent studies dealing with the selection of new promising microbial stains and plant varieties involved in the treatment of radioactive and heavy metal contaminants. It provides a detailed description of the biochemical mechanisms and genes involved in the bioremediation of radionuclides and heavy metals, offering a clear insight for academics and practitioners interested in in vitro and in situ biological treatment. This book will be of great value to students and scholars interested in environmental pollution and environmental health from across a range of different disciplines, including environmental microbiology and chemistry, ecology and environmental science, biological and environmental engineering and biotechnology.

This book presents in detail the state of knowledge of the distribution, bioavailability, biomagnification, discrimination, fate and sources of chemical pollutants (metals, metalloids, radionuclides and nutrients) in all compartments (atmosphere, water, deposits, biota) of the Baltic environment. Particular components of the Baltic ecosystem are considered as potential monitors of pollutants. Budgets of chemical elements and the ecological status of the Baltic Sea in the past, present and future are presented. Estimates of health risks to man in respect to some toxic metals and radionuclides in fish and seafood are briefly discussed. The content of the book makes possible the identification of gaps in our environmental knowledge of the Baltic Sea, with certain sections establishing possible priorities, key areas or strategies for future research.

This book focuses on the mechanistic (microscopic) understanding of radionuclide uptake by plants in contaminated soils and potential use of phytoremediation. The key features concern radionuclide toxicity in plants, how the radioactive materials are absorbed by plants, and how the plants cope with the toxic responses. The respective chapters examine soil classification, natural plant selection, speciation of actinides, kinetic modeling, and case studies on cesium uptake after radiation accidents. Radionuclide contaminants pose serious problems for biological systems, due to their chemical toxicity and radiological effects. The processes by which radionuclides can be incorporated into vegetation can either originate from activity interception by external plant surfaces (either directly from the atmosphere or from resuspended material), or through uptake of radionuclides via the root system. Subsequent transfer of toxic elements to the human food chain is a concrete danger. Therefore, the molecular mechanisms and genetic basis of transport into and within plants needs to be understood for two reasons: The effectiveness of radionuclide uptake into crop plants – so-called transfer coefficient – is a prerequisite for the calculation of dose due to the food path. On the other hand, efficient radionuclide transfer into plants can be made use of for decontamination of land – so-called phytoremediation, the direct use of living, green plants for in situ removal of pollutants from the environment or to reduce their concentrations to harmless levels.

The goal of this book is to examine the complex state of radioactivity in the environment, and to understand the interplay of its two principal sources: man-made and natural. The text examines human contributions to release of radionuclides, with an eye to future reductions, and assesses natural occurrences in an evaluation of baseline radioactivity.

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.

Edited by One of the Best Specialists in Soil Science Recent studies reveal that Phosphorus (P) in the form of phosphate, a macronutrient essential for plant growth, and crop yields can influence the bioavailability, retention, and mobility of trace elements, metal(loid)s, and radio nuclides in soils. When this occurs, phosphates can affect the dynamics of heavy metals and influence soil characteristics, impacting soil mobility and toxicity. Phosphate in Soils: Interaction with Micronutrients, Radionuclides and Heavy Metals utilizes the latest research to emphasize the role that phosphate plays in enhancing or reducing the mobility of heavy metals in soil, and the soil-water-plant environment. It provides an in-depth understanding of each heavy metal species, and expands on phosphate interactions in geological material. Composed of 12 chapters, this text: Provides an overview of the reactions of metal(loid)s and common P compounds that are used as fertilizer in soils Emphasizes the effect of phosphorus on copper and zinc adsorption in acid soils Discusses findings on the influence of phosphate compounds on speciation, mobility, and bioavailability of heavy metals in soils as well as the role of phosphates on in situ and phytoremediation of heavy metals for contaminated soils Places emphasis on the influence of phosphate on various heavy metals species in soils, and their solubility/mobility and availability Provides extensive information on testing various high phosphate materials for remediation of heavy metal, micronutrients, and radionuclides contaminated sites Explores the reactivity of heavy metals, micronutrients and radionuclides elements in several soils Presents a case study illustrating various remediation efforts of acidic soils and remediation of Cu, Zn, and lead (Pb) contaminated soils around nonferrous industrial plants Emphasizes the significance of common ions (cations and anions) on phosphate mobility and sorption in soils, and more The author includes analytical and numerical solutions along with hands-on applications, and addresses other topics that include the transport and sorption modeling of heavy metals in the presence of phosphate at different scales in the vadose zone.

This book examines the way that lead enters the biosphere and the subsequent environmental impact. The contributing authors include international experts who provide methods for assessing and characterizing the ecological risk of lead contamination of soil and plants. Information is provided on the consequences for human health as a result of lead pollution. This book reveals that approximately 98% of stable lead in the atmosphere originates from human activities. Lead in Plants and the Environment reports on methods for detecting, measuring, and assessing the concentration of lead in plants. The authors provide a method for the measurement of 210Pb isotopes in plants. This method can be applied extensively in different environmental settings, not only as a way of revealing sources of lead, but also as a way to monitor lead transport in plants and animals that ingest them. The chapters include coverage on the following topics: · Lead bioavailability in the environment and its exposure and effects · Radioanalytical methods for detecting and identifying trace concentrations of lead in the environment · Lead contamination and its dynamics in soil plant systems · Lead pollution monitoring and remediation through terrestrial plants in mesocosm constructed wetlands · A review of phytoremediation of lead This book is a valuable resource to students, academics, researchers, and environmental professionals doing field work on lead contamination throughout the world.

In the past two decades there has been an increasing public awareness of the hazards that exist from the contamination of the environment by toxic substances. 'Heavy metals' and the terrestrial environment are but one facet of the impact of toxic substances on the natural environment, and the use of biological materials for indicating the occurrence of, and continually monitoring the presence of, these materials is a specific topic which is of considerable interest to a diverse range of individuals, organisations and disciplines. It was our intention when we first en visaged this book that it should contain a description of a range of circumstances in which biological monitoring techniques have been employed in the terrestrial environment and that it should be seen as a practical text which dealt with the merits, shortcomings and suitability of biological monitoring materials. Monitoring is, however, a manifold process. It serves not only to provide information on past and present concentrations of toxic materials in various components of the environ ment, but also to provide information on the processes of environmental release, transport, accumulation and toxicity. Indeed, this may be one of the greatest virtues of biological monitoring over other forms of monitor ing. According to the skill of the staff employed in the monitoring procedure, the information that is accrued can have a vastly different value.
