Book excerpt: El suelo y subsuelo constituyen un recurso natural dificilmente renovable y que desempena funciones entre las que destaca su papel como medio filtrante durante la recarga de los mantos acuiferos y la proteccion de los mismos. El suelo y subsuelo tambien estan integrados al escenario donde ocurren los ciclos biogeoquimicos, hidrologicos y las redes troficas, ademas de ser el espacio donde se realizan las actividades agricolas, ganaderas y es el soporte de la vegetacion. Los metodos existentes para tratar los suelos contaminados pueden ser de naturaleza fisica, quimica o biologica y tanto unos como otros pueden aplicarse en el lugar de la contaminacion, in situ, o como tratamiento ex situ; siendo los primeros los mas recomendados. Dentro de las tecnologias emergentes de remediacion destaca el uso de particulas biocatalizadoras. Se emplea el termino de particulas biocatalizadoras cuando se inmovilizan microorganismos en alginato de calcio y las celulas son capaces de participar como agentes en reacciones quimicas o bioquimicas. Se ha demostrado la factibilidad de emplear las particulas biocatalizadoras en la remocion de contaminantes en medio acuoso."

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: La remediación de suelos contaminados ha tomado un gran auge en los últimos años debido a la aprobación de normatividades que regulen este problema. Dentro de las técnicas de remediación más utilizadas se encuentran los tratamientos biológicos, ya que representan procesos de bajo costo y fácil operación, aunado a la amplia variedad de compuestos orgánicos e inorgánicos que pueden ser tratados. En varios estudios se ha demostrado la factibilidad de utilizar la técnica de bioventeo, la cual consiste en el suministro de una corriente de aire por la matriz del suelo, para el tratamiento de Hidrocarburos Totales de Petróleo (HTP's). La bioaumentación, la cual consiste en la adición de microorganismos exógenos capaces de degradar el contaminante presente en la matriz de suelo es otra técnica de biorremediacón que ha incrementado su uso debido a los beneficios que conlleva en costo y tiempo; sin embargo, aún existen áreas necesitadas de investigación como son la biorremediación de Hidrocarburos Policíclicos Aromáticos (HPA's) presentes en Fases Líquidas No Acuosas (NAPL's). Por tal motivo, en el presente estudio se planteó como objetivo el analizar la efectividad del uso del bioventeo y bioaumentación en suelo contaminado con un NAPL el cual contenía concentraciones conocidas de naftaleno y fenantreno, con el fin de establecer el potencial de degradación de HPA's. Se utilizó como suelo arena de río la cual fue contaminado con naftaleno y fenantreno presentes en un NAPL. Se estudió el efecto en las tasas de remoción de contaminantes debido a la inoculación del suelo con una cepa denominada como pseudomonas putida, en contraste con aquellos suelos que solo contenían microorganismos nativos. En las 12 unidades de tratamiento estudiadas, circulaba una corriente de aire húmedo que proporcionaba el oxígeno necesario para el proceso de biodegradación, además de mantener las condiciones de humedad requeridas en el suelo.

Available in PDF, EPUB and Kindle. Book excerpt: El problema de contaminación de aguas y suelos más habitual lo constituyen las fugas de combustibles durante su almacenamiento o transportación. El tratamiento por bioremediación o tratamiento microbiológico aumentado de ambientes contaminados con una variedad de compuestos orgánicos e inorgánicos, es una tecnología efectiva de resiente surgimiento. Un aspecto de controversia excepcional del trabajo es la bioaumentación; la adición de microorganismos al suelo. En el presente trabajo de investigación se utilizó una muestra de suelo contaminada con hidrocarburos (Diesel/Aceite) con una concentración inicial de 110,000 ppm; proveniente de un taller de ferrocarriles en Empalme Sonora, México. Por lo que el suelo estuvo sujeto a los fenómenos de intemperización previo a la bioremediación y la fracción de hidrocarburos de menor peso molecular no estaba ya presente en el suelo. En el laboratorio se trató de simular las condiciones para la remediación del suelo por la técnica denominada biopila/composteo. El estudio comprendió la utilización de un agregado orgánico (estiércol de vaca), agregado inorgánico (urea), surfactante y cultivo bacteriano; con un contenido de humedad del suelo del 20%. Encontrándose que la mejor estimulación de la actividad microbiológica del suelo se obtuvo con la adición del agregado orgánico y el cultivo bacteriano, resultando en una remoción del 82% de TPH's durante un periodo de 100 días. En comparación con la muestra control (sin agregados) donde se registró una reducción del 54% de TPH's en el mismo periodo de tiempo. La utilización del agregado orgánico (estiércol de vaca) presentó buenos resultados respecto a la degradación de los hidrocarburos presentes en el suelo, además de proporcionarle una mejor textura al suelo y mayor capacidad de retención de humedad.

This book was released on 2012-05 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: La contaminacion del suelo tiene consecuencias muy diversas, desde el propio riesgo toxicologico para la salud humana o ecotoxicologico para el medio, como perdidas de recursos naturales, riesgos de explosion o perdidas economicas. La problematica de la contaminacion de suelos no es un problema actual, aunque si su tratamiento. En Espana hace solo 14 anos que se definio el significado de un suelo contaminado, y que en la Comunidad de Madrid se hizo un inventario de suelos contaminados, siendo este uno de los primeros a nivel nacional. El objetivo de este proyecto es la remediacion de un suelo arenoso, para alcanzar unas concentraciones aceptables desde el punto de vista toxicologico como medioambiental, tras producirse una fuga de un deposito de combustibles que conlleva a la contaminacion del suelo por compuestos volatiles. Los contaminantes a tratar son los denominados compuestos BTEX: Benceno, Tolueno, Etilbenceno y Xileno presentes en el combustible. La tecnologia escogida es la extraccion de vapor, siendo esta una tecnica in-situ poco invasiva. Este tratamiento resulta el mas apropiado para el suelo en cuestion teniendo en cuenta criterios de aplicabilidad, coste y eficacia."

Book Synopsis Times Gone By by : Vicente Pérez Rosales
Download or read book Times Gone By written by Vicente Pérez Rosales and published by Oxford University Press. This book was released on 2003-05-01 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: These memoirs trace the wild and adventurous life of Pérez Rosales from his childhood up to the 1860s. During that approximately half-century he saw and did more than a dozen ordinary men. At age eleven in Argentina he witnessed the executions of Luis and Juan Jose Carrera. From there, his activities and adventures took him on several journeys on sailing vessels around Cape Horn; to Paris, where he witnessed the July revolution of 1830; to various commercial endeavors including a distillery, the practice of medicine, and cattle smuggling; into service as an advisor to an Argentine warlord; as a miner for precious metals in the north of Chile; as participant in the California Gold Rush in 1849; as director of the government's project for German immigration and settlement in the wild south of Chile; and also as Chilean consul and immigration agent in Hamburg. Around the world, Rosales lived through many of his era's watershed moments. His exciting memoirs offer a chance to relive the rush and chaos of these times--from a much safer vantage.

Book Synopsis Developments in Surface Contamination and Cleaning by : Rajiv Kohli
Download or read book Developments in Surface Contamination and Cleaning written by Rajiv Kohli and published by Elsevier. This book was released on 2008-01-10 with total page 1209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface contamination is of cardinal importance in a host of technologies and industries, ranging from microelectronics to optics to automotive to biomedical. Thus, the need to understand the causes of surface contamination and their removal is very patent. Generally speaking, there are two broad categories of surface contaminants: film-type and particulates. In the world of shrinking dimensions, such as the ever-decreasing size of microelectronic devices, there is an intensified need to understand the behavior of nanoscale particles and to devise ways to remove them to an acceptable level. Particles which were functionally innocuous a few years ago are ôkiller defectsö today, with serious implications for yield and reliability of the components. This book addresses the sources, detection, characterization and removal of both kinds of contaminants, as well as ways to prevent surfaces from being contaminated. A number of techniques to monitor the level of cleanliness are also discussed. Special emphasis is placed on the behaviour of nanoscale particles. The book is amply referenced and profusely illustrated. • Excellent reference for a host of technologies and industries ranging from microelectronics to optics to automotive to biomedical. • A single source document addressing everything from the sources of contamination to their removal and prevention. • Amply referenced and profusely illustrated.

Book Synopsis Oiling the Urban Economy by : Franklin Obeng-Odoom
Download or read book Oiling the Urban Economy written by Franklin Obeng-Odoom and published by Routledge. This book was released on 2014-06-13 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a critical analysis of the ‘resource curse’ doctrine and a review of the international evidence on oil and urban development to examine the role of oil on property development and rights in West Africa’s new oil metropolis - Sekondi-Takoradi, Ghana. It seeks answers to the following questions: In what ways did the city come into existence? What changes to property rights are oil prospecting, explorations, and production introducing in the 21st century? How do the effects vary across different social classes and spectrums? To what extent are local and national institutions able to shape, restrain, and constrain trans-national oil-related accumulation and its effects on property in land, property in housing (residential, leisure, and commercial), and property in labour? How do these processes connect with the entire urban system in Ghana? This book shows how institutions of varying degrees of power interact to govern land, housing, and labour in the city, and analyses how efficient, sustainable, and equitable the outcomes of these interactions are. It is a comprehensive account of the tensions and contradictions in the main sectors of the urban economy, society, and environment in the booming Oil City and will be of interest to urban economists, development economists, real estate economists, Africanists and urbanists.
Book Synopsis Vehicular Air Pollution by : Bekir Onursal
Download or read book Vehicular Air Pollution written by Bekir Onursal and published by World Bank Publications. This book was released on 1997-01-01 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much is expected of private financing to help meet the infrastructure requirements of the rapidly growing East Asian economies. Although private financing grew briskly during the 1990s, it represents only a small share of all infrastructure investment in the region (between 12 and 18 percent). This monograph draws on experience in a number of countries in East Asia, as well as Australia, Chile, and India, to analyze the impediments to and prospects for private financing of infrastructure. The chapters discuss the choices available to policymakers and the strategies that governments have followed. An overview chapter describes recent trends in international financing of infrastructure projects in the region, discusses the key policy and institutional impediments to greater private participation, and assesses the role of domestic capital markets and finance. It also outlines a national and regional strategy for stimulating private investment in infrastructure. The case studies from countries outside East Asia illustrate the payoffs of increased integration and concerted moves toward private provision of infrastructure.
