Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Available in PDF, EPUB and Kindle. Book excerpt: Humedales para tratamiento es el séptimo volumen de la serie “Tratamiento biológico de aguas residuales” (en inglés “Biological Waste Water Treatment Series”), que provee una presentación de vanguardia sobre la ciencia y tecnología del tratamiento de aguas residuales. Los principales tipos de sistemas de humedales son tratados en este volumen, a saber: (i) Humedales de flujo subsuperficial horizontal, (ii) Humedales de flujo vertical; (iii) Humedales de flujo vertical tipo francés; (iv) Humedales intensificados; (v) Humedales de flujo libre; (vi) otras aplicaciones de los humedales para tratamiento. El libro presenta en forma clara y didáctica, los conceptos básicos, los principios de la tecnología, desempeños esperados, criterios de diseño, ejemplos de diseño, aspectos constructivos y guías para la operación. El libro ha sido escrito en su versión inglesa, y traducido al castellano, por un equipo internacional de expertos en el campo de los humedales para tratamiento.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: What are the environments, the public spaces, in which ordinary people become participants in the complex, ambiguous, engaging conversation about democracy: participators in governance rather than spectators or complainers, victims or accomplices? What are the roots, not simply of movements against oppression, but also of those democratic social movements which both enlarge the opportunities for participation and enhance people's ability to participate in the public world? In Free Spaces, Sara M. Evans and Harry C. Boyte argue for a new understanding of the foundations for democratic politics by analyzing the settings in which people learn to participate in democracy. In their new Introduction, the authors link the concept of free spaces to recent theoretical discussions about community, public life, civil society, and social movements.

Book excerpt: This volume is based on the recognition that heritage is popular and popular culture is now readily transformed into heritage, whose meanings and myths reshape social life and political and economic realities, as well as re-make "tradition". The papers in this volume consider: What does popular heritage look like? To whom does it speak? Is it active in dissolving class and cultural boundaries or just in reproducing new ones? How do societies manage a heritage that is fluid, immediate and that straddles extremes of serious conflict and hedonistic frivolity? When and under what circumstances is the creation and expression of new cultural forms - popular culture - capable of being transformed into heritage?

Book excerpt: The long-term productivity of forest ecosystems depends on the cycling of nutrients. The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.
