Book Description
La recuperacion de los suelos contaminados con elementos traza y metales pesados resulta muy dificil debido a que estos no son degradables, al contrario que los contaminantes organicos o los radionucleidos de vida corta. La mayoria de las tecnicas de recuperacion se basan en metodos fisicos y quimicos economicamente costosos y que alteran drasticamente la estructura y las propiedades fisico-quimicas del suelo. Sin embargo, en la ultima decada ha crecido el interes por el desarrollo de tecnicas respetuosas con el medioambiente y economicamente viables. Dentro de estas tecnicas esta la Recuperacion Natural Asistida, basada en la utilizacion de enmiendas y/o plantas que aceleran los procesos de adsorcion, precipitacion y complejacion que ocurren de forma natural en el suelo, los cuales disminuyen la movilidad y la biodisponibilidad de los contaminantes. Dicha tecnica estimula asimismo la actividad microbiana del suelo y el reciclado de nutrientes. El presente trabajo representa un estudio detallado y unico sobre el potencial de varias enmiendas y/o el desarrollo de cubiertas vegetales para estabilizar elementos traza en el suelo y recuperar suelos contaminados con dichos elementos.

Book Description
The environment is considered the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people who are by and large ruining the environment both for themselves and for all other organisms. This book reviews the latest research in this field which is vital for everyone.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.
