Overall, 30 researchers will take part in this event coming from several universities (Alicante, Cantabria, Rovira i Virgili, Salamanca, Sevilla, and Valladolid) and the IMDEA Materials Institute. The program includes a plenary lecture imparted by Prof. Grossmann, one keynote presentation representative of each institution and around 15 oral presentations from young researchers.
Book Synopsis Use of an Upflow Column Leaching Test to Study the Release Patterns of Heavy Metals from Stabilized/Solidified Heavy Metal Sludges by : TM. Brown
Download or read book Use of an Upflow Column Leaching Test to Study the Release Patterns of Heavy Metals from Stabilized/Solidified Heavy Metal Sludges written by TM. Brown and published by . This book was released on 1986 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stabilization/solidification of hazardous liquids and sludges with portland cement has been investigated as a method of treatment that will bind hazardous materials in a form that minimizes adverse effects on the environment after landfilling. Research has been conducted to determine the long-term acceptability of this technique for disposal of heavy metal sludges by determining the rate of release of metals from solidified/stabilized wastes. The primary concern of this research was to determine the manner in which the heavy metals are released from the paste, as this will be important in extrapolation of the short-term leaching test results to long time periods. These studies utilized upflow leaching columns to determine the effects of acid flux (meq/g/day) and waste particle size on the release of metals from the solidified cement paste containing heavy metal sludges. Two particle size ranges and two acid fluxes were evaluated. Leachates from the column were collected on a daily basis and analyzed for pH, alkalinity, cadmium, chromium, and lead. Release patterns were modelled successfully using a diffusion-based equation. An effective diffusion coefficient and leachability index were calculated for each combination of heavy metal, particle size, and acid flux. These values can be used to predict metal release rates.

Book Synopsis Evaluation of the Removal of Heavy Metals from Contaminated Sediment in Continuous Flow Tests with Selective Sequential Extraction by : B. Dahrazma
Download or read book Evaluation of the Removal of Heavy Metals from Contaminated Sediment in Continuous Flow Tests with Selective Sequential Extraction written by B. Dahrazma and published by . This book was released on 2006 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solutions to heavy metal-contaminated sediment require the understanding of the availability of heavy metals, interaction of the contaminants with soil and sediment particles, and metal retention mechanisms, which are complicated phenomena. The objective of this investigation was to study the removal of heavy metals (copper, zinc, and nickel) from the sediments by employing a biosurfactant rhamnolipid in continuous flow tests. Continuous flow of the biosurfactant in a column was applied to evaluate the feasibility of this type of setup since the configuration simulates the process of soil flushing. In the case of heavy metals, the flowing washing agent is believed to reduce the possibility of readsorption of the metals on to the soil and sediment. In addition, since the distribution of heavy meals between soil and solute is the key to evaluating the environmental impact of the metals, to determining the mobility of metals and to recommending reliable removal techniques, selective sequential extraction tests were used to determine the portion of sediment from which the metal was removed. This method is based on extracting metals with solutions of increasing strengths from different fractions of soils or sediments. Exchangeable, carbonate, reducible oxide, and organic fractions responded to washing techniques while residually bound contaminants are not economical or feasible to remove. This information is vital in proposing the most appropriate conditions for sediment washing.

Book Synopsis Sediment Toxicity Assessment by : G.Allen Burton
Download or read book Sediment Toxicity Assessment written by G.Allen Burton and published by CRC Press. This book was released on 2018-05-04 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Toxicity Assessment provides the latest information regarding how to evaluate sediment contamination and its effects on aquatic ecosystems. It presents an integrated ecosystem approach by detailing effective assessment methods, considerations, and effects to each major component of marine and freshwater systems, including the benthos, plankton, and fish communities. The approaches emphasize defining habitat conditions (physical and chemical), toxicant bioavailability, factors influencing toxicity (lab and field), biomarkers, acute and chronic toxicity, study design, collection methods, and EPA management strategies. The book also explains how to integrate the assessments. Sediment Toxicity Assessment will be useful to to all environmental managers, environmental scientists, ecotoxicologists, environmental regulators, aquatic ecologists, environmental contractors and consultants, instructors, students, conservation commissions, and environmental activist organizations.

Book Synopsis Bioavailability of Contaminants in Soils and Sediments by : National Research Council
Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Book Synopsis Contaminated Sediments by : Ulrich Förstner
Download or read book Contaminated Sediments written by Ulrich Förstner and published by Springer. This book was released on 1989-04-12 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediments are increasingly recognized as both a carrier and a possible source of contaminants in aquatic systems, and they may also affect groundwater quality and agricultural products when disposed on land. Four aspects are covered reflecting the development of knowledge in particle-associated pollutants during the past twenty-five years: - the identification, surveillance, monitoring and control of sources and distribution of pollutants, - the evaluation of solid/solution relations of contaminants in surface waters, - the study of in-situ processes and mechanisms of pollutant transfer in various compartments of the aquatic ecosystems, - the assessment of the environmental impact of particle-bound contaminants, i.e. the development of sediment quality criteria. A final chapter focusses on practical aspects concerning contaminated sediments.
