Download or read book Assessing Speciation and Availability of Heavy Metals in Soils and Soil Solutions written by Zongling Ren and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The elevated heavy metal contamination in soils has given rise to the accurate assessment of the availability and mobility of heavy metals and the development of remediation strategies. In this study, soi! column-Donnan membrane technique (SC-DMT) and diffusive gradients in thin¬films gels (DGT) were used to measure the concentration and speciation of Cd, Cu, Ni, Pb, and Zn in eighteen soil solutions, covering a wide range of metal sources (natural and anthropogenic) and concentrations. The availability of Cd, Cu, Pb, and Zn in nine contaminated soils was evaluated by combining chemical extractions with multi-elementary stable isotopic dilution (ID) method. The isotopically exchangeable pool and the operationally defined pool determined by chemical extractions were then compared to probe the relationships between metal availabilities and their bearing phases. The mufti-surface model was used to assess the rote of the major soil components (organic matter, clay, iron hydroxides, and manganese hydroxides) in controlling metal availability. The combination of analytical approaches and speciation modeling can provide mutual validation and a more comprehensive picture of the availability of metals. In our work, model calculation generally provided an adequate prediction of metal speciation in soi! solution and solid phase, and it can be a promising tool to decipher the underlying mechanisms of the differences in metal availabilities in soils.

Available in PDF, EPUB and Kindle. Book excerpt: Land contaminated with heavy metals such as Cd and Zn can be remediated using a number of different approaches. Many of these strategies are very expensive (e. g. removal and disposal of the soil, covering the soil with uncontaminated soil, extraction with acids or chelates) whilst others provide only short term solutions (e. g. reduction of metal bioavailability by liming or adding organic matter). An alternative approach is the use of hyperaccumulator plants to remove the heavy metals. Phytoremediation, as this process is known, is an attractive method for remediation of contaminated land since it is relatively inexpensive and has the potential through the appropriate selection of plant species to be effective. However, there are many factors that need to be considered for phytoremediation, perhaps the most important is the bioavailability of metals from different component or functional pools within the soil. The bioavailability of heavy metals has been assessed through a variety of approaches, with extraction using chemicals being the most common. Another approach is the isotopic exchange method which has been regularly used for estimating the bioavailable P in soil. This technique relies on the assumption that isotopically exchangeable P is available to a growing plant and yields the so called E-value for a soil. In past studies, particularly in highly P fixing soils, the E-value has been shown to overestimate the soil available P. To overcome this a second procedure based on the measurement of isotope uptake by a plant growing on a spiked soil has been proposed and yields the so called L-value. As well as P, this method has been applied to Ni and only very recently to Cd and Zn using radioisotopes. In the present work, stable isotopes are used for the first time to measure the Cd and Zn available for plant uptake using isotopic exchange principles based on the E and L-values using a contaminated (Great Billings) and a non-contaminated (Countesswells) soil. The.

Download or read book Advances in Microbe assisted Phytoremediation of Polluted Sites written by Kuldeep Bauddh and published by Elsevier. This book was released on 2022-08-03 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Microbe-assisted Phytoremediation of Polluted Sites provides a comprehensive overview of the use of phytoremediation to decontaminate polluted land through microbial enhanced phytoremediation, including the use of plants with respect to ecological and environmental science. The book discusses the potential of microbial-assisted phytoremediation of the contaminant, including heavy metals, pesticides, polyaromatic hydrocarbons, etc., with case studies as examples. Key subjects covered include plant-microbe interaction in contaminated ecosystems, microbe-augmented phytoremediation for improved ecosystem services, and success stories on microbe-assisted phytoremediation of contaminated sites. With increasing demand for land-space for social, industrial and agricultural use, the theoretical millions of hectares of contaminated sites around the world are a resource sorely needed that currently cannot be utilized. Decontamination of this land using ecologically-sound methods is paramount not only to land use, but in the prevention of toxic substances deteriorating local ecosystems by reducing productivity and contaminating the food chain – which can eventually aggregate in food chains and pose the potential risk of non-curable diseases to humans such as cancer. - Provides novel information on the potential for microbial inoculants to be used in phytoremediation - Discusses principles and mechanisms of plant-microbe interaction for enhanced phytoremediation with improved soil health - Investigates phytoremediation solutions for a multitude of contaminants, including heavy metals, fly ash, petroleum, arsenic, TPH, mining effluents, fluoride, lead and other major pollutants

Download or read book Agromining Farming for Metals written by Antony van der Ent and published by Springer. This book was released on 2017-10-28 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on global agromining/phytomining technology. It presents the complete metal farming or agromining chain; an emerging technology expected to be transformative in the extraction of resources of those elements not accessible by traditional mining techniques. Meeting the demand for critical minerals (rare earth elements, platinum group elements, nickel cobalt) is increasingly difficult in the 21st century due to resource depletion and geopolitical factors. Agromining uses hyperaccumulator plants as “metal crops” farmed on sub-economic soils or mineral waste to obtain valuable elements. This book, which follows the metal farming chain, starts with the latest information on the global distribution and ecology of hyperaccumulator plants, biogeochemical pathways, the influence of rhizosphere microbes, as well as aspects of propagation and conservation of these unusual plants. It then presents the state of the art in new tools for identifying hyperaccumulator plants and for understanding their physiology and molecular biology. It goes on to describe the agronomy of “metal crops,” and opportunities for incorporating agromining into rehabilitation and mine closure, including test-cases of nickel, cobalt, selenium, thallium, rare earth elements and PGEs. Finally, it concludes with an overview of the latest developments in the processing of bio-ores and associated products. This book is edited and authored by the pioneers in the field who have been at the foreground of the development of agromining over the past three decades. It is timely as agromining is now at a pivotal point in its development with rapid expansion of activities in the field around the globe. As such it is of interest to environmental professionals in the minerals industry, government regulators and academics.
