Book Description
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.

Book Description
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.

Book Description
Soil as World Heritage celebrates a half century of field experiments on the Balti Steppe, in Moldova - where Dokuchaev first described the Typical Chernozem in 1877, protected from the elements by a unique system of shelter belts designed by the great man, and now provisionally listed as the first World Heritage Site for soil. The book presents contributions to the 2012 international symposium attended by researchers, practitioners and policy makers from the European Commission and countries as diverse as Belarus, Bulgaria, the Czech Republic, France, Germany, Italy , the Netherlands, Romania, Russia, Ukraine, United Kingdom, USA and, of course, Moldova itself. The experimental data demonstrate the damage caused by human activity to the productivity and integrity of the black earth and, also, ways to restore its fertility. Results from even longer-established trials worldwide also demonstrate that agricultural practices are driving global warming, leaching of nutrients, pollution of water resources, diversion of rainfall away from replenishment of soil and groundwater to destructive runoff, and destroying soil organic matter and biodiversity. These are pressing issues for our generation and will press harder on future generations. Long-term field experiments, and the scientific skills and experience that they nurture, will be more and more valuable as a foundation and focus for interdisciplinary teams studying the effects of farming practices on the soil and soil life so as to devise a sustainable alternative. Europe-wide and worldwide contributions also discuss economic incentives - carbon and green water credits - which themselves require robust supporting data, and legislative aspects of promoting more sustainable farming systems. The outcomes of the conference include recommendations for institutional support for sustainable farming and a draft of the law on land and soil management for the Parliament of Moldova.

Book Description
Metal contamination is an increasing ecological and eco-toxicological risk. Understanding the processes involved in metal mobilization, sorption and mineralization in soils are key features for soil bioremediation. Following an introduction to the physical, chemical and biological components of contaminated soils, various chapters address the interactions of soil, microorganisms, plants and the water phase necessary to transfer metals into biological systems. These include topics such as potential hazards at mining sites; rare earth elements in biotic and abiotic acidic systems; manganese redox reactions; biomineralisation, uranium in seepage water; metal-resistant streptomycetes; mycorrhiza in re-forestation; metal (hyper)accummulation in plants; microbial metal uptake; and their potential for bioremediation. This book will be of interest to soil biologists, geologists and chemists, researchers and graduate students, as well as consulting companies and small enterprises involved in bioremediation.

Book Description
Predicting the potential migration of metals and radionuclides from waste pits and trenches will require understanding the effects of carbon and electron flow through these environments. Important aspects of this flow include the physiological activity of cellulolytic and non-cellulolytic fermentative microbial populations, as well as the subsequent activity of metal and radionuclide reducing bacteria. The activity of subsurface fermentative microbial populations is significantly understudied even though these organisms can affect contaminant migration by at least two mechanisms. In the first mechanism, products of the fermentation process can act as chelators for metals and radionuclides increasing their transport through underlying geological media. The second mechanism is the reduction and immobilization of metals and radionuclides since some fermentative bacteria have been shown to directly reduce metals and radionuclides, while their fermentation products can provide carbon and energy for respiratory metal reducing bacteria that can also reduce oxidized metals and radionuclides.

Book Description
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.
