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 Study of Desorption of Contaminant from Synthetic Soil by : Kung-Fu Hwang
Download or read book Study of Desorption of Contaminant from Synthetic Soil written by Kung-Fu Hwang and published by . This book was released on 1996-12-01 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: A better understanding of sorption and desorption processes could improve estimates of time and cost required for remedial activities, exposure times and health risk, and bioavailability. Conventional rate-limited sorption models do not accurately define the diffusion domain at the grain scale. Heyse (1994) proposed the multiple sites in series (MSS) model, which allows more general description of the geometry of the sorption domain than the classical spherical or discrete distributions. A version of this model was tested by deVenoge (1996). The model was able to accurately simulate sorption rate data, but could not estimate unique geometry parameters. This research is to develop techniques to study desorption, and compare the results to the sorption study conducted by deVenoge (1996). This study examines whether sorption and desorption of anthracene by paraffin are reversible processes. The ability of the MSS model to predict geometry parameters was also tested. One finding of this study was the apparent volatilization of anthracene from wax during the heating and molding processes. This phenomenon may be responsible for the non- zero intercept of the desorption isotherm. It may have also confounded the initial conditions required by the MSS model in predicting the sorption distribution. If the initial concentration of anthracene in the wax is adjusted, the desorption process does appear to be the reverse of the sorption process. The equilibrium partition coefficients for sorption and desorption are similar. The diffusion coefficient appears to be faster for desorption than sorption, but this may have been affected by solvation of the paraffin. The MSS model did not successfully predict geometry parameters, possibly due to uncertain initial concentration in wax.

Download or read book Handbook of Research on Green Synthesis and Applications of Nanomaterials written by Garg, Rajni and published by IGI Global. This book was released on 2022-01-14 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials can be synthesized by physical, chemical, and biological methods; however, the latter technique is preferred as it is eco-friendly, non-toxic, and cost-effective. The green synthesized nanomaterials have been found to be more efficient with potential applications in diverse fields. It is crucial to explore green synthesized nanomaterials and the applications that can be made in order to support water remediation, pharmaceuticals, food processing, construction, and more. The Handbook of Research on Green Synthesis and Applications of Nanomaterials provides a multidisciplinary approach to the awareness of using non-toxic, eco-friendly, and economical green techniques for the synthesis of various nanomaterials, as well as their applications across a variety of fields. Covering topics such as antimicrobial applications, environmental remediation, and green synthesis, this book acts as a thorough reference for engineers, nanotechnology professionals, academicians, students, scientists, and researchers pursuing research in the nanotechnology field.

Book Synopsis Soil pollution: a hidden reality by : Food and Agriculture Organization of the United Nations
Download or read book Soil pollution: a hidden reality written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-04-30 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.

Book Synopsis Contaminant Geochemistry by : Brian Berkowitz
Download or read book Contaminant Geochemistry written by Brian Berkowitz and published by Springer Science & Business. This book was released on 2014-04-22 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this updated and expanded second edition, new literature has been added on contaminant fate in the soil-subsurface environment. In particular, more data on the behavior of inorganic contaminants and on engineered nanomaterials were included, the latter comprising a group of “emerging contaminants” that may reach the soil and subsurface zones. New chapters are devoted to a new perspective of contaminant geochemistry, namely irreversible changes in pristine land and subsurface systems following chemical contamination. Two chapters were added on this topic, focusing attention on the impact of chemical contaminants on the matrix and properties of both liquid and solid phases of soil and subsurface domains. Contaminant impacts on irreversible changes occurring in groundwater are discussed and their irreversible changes on the porous medium solid phase are surveyed. In contrast to the geological time scale controlling natural changes of porous media liquid and solid phases, the time scale associated with chemical pollutant induced changes is far shorter and extends over a “human lifetime scale”.
