The occurrence of heavy metals in the environment, even in traces, represents a severe risk for the ecosystems and can be dangerous to human health. However, a better understanding of the main aspects involved is still needed to reduce its negative impact on the environment and health. This book covers the recent methods used for the evaluation of heavy metal pollution and the identification of its sources, descriptions of some of the processes involved in its mobility and transport, attempts to address health and environmental effects of heavy metals pollution, and presents alternative technologies for its removal and remediation from environmental samples. Therefore, this book is recommended for experts in the comprehensive management of metal contamination in different environmental compartments.

Mercury is a serious environmental toxin that is distributed globally by large-scale atmospheric circulations. The chapters in this book cover measurements of speciated atmospheric mercury, regional modeling, continental-scale distributions across the U.S. and Canada, large-scale distributions in the free troposphere, and changes in wet deposition across the U.S. The diverse topics give snap-shots of current research areas in atmospheric mercury and some insight into policy issues in Europe. Together, the work demonstrates the complexity of atmospheric mercury and provides aspects on measuring and modeling it. Much work is needed in the future to unravel the chemical forms of oxidized atmospheric mercury and how it is intertwined in global cycling of mercury. The complexities of this work are extremely challenging for emerging atmospheric chemists.

The last decade has seen the rise of urban design which has taken a central position in the new agendas for urban regeneration and renaissance. Urban design has moved from marginality to mainstream. The principles espoused by urban designers over the past thirty years are now accepted as key to a better urban environment and as we move towards greater sustainability, different ideas are emerging that are challenging some of the accepted urban design norms; urban design is at a watershed. Urban Design Futures presents essays from an international cast of authors to review progress and explore emerging ideas: should urban design reflect the future rather than recreate the past? What are the new driving forces that will shape urban living and hence urban design in the future? This book explores new concepts and points the way towards a series of urban design paradigms for the twenty-first century.

Urban planning intends to promote urban living conditions through reasonable land use, always maintaining harmony between urban planning and nature. The cities are the focus of growth within states; their industrialization and growth in housing large populations worldwide have caused a disordered and chaotic development. The objective of planning is to correct the urban chaos and prevent it from happening again due to inadequate planning, thus improving inhabitants' quality of life. Contextually, urban green spaces are a pivotal piece of this puzzle. In fact, the existence of abundant vegetation in cities has a universal appeal that persists beyond temporal, spatial, and cultural divisions, incorporating itself within the concept of environmental quality and leading to a better quality of life. Thereby, it is essential to assess and analyze the design, function, and role of urban green spaces in today's and tomorrow's cities.

"This book explores the existential redistributions that extractivist frontiers create, going beyond existing studies by bringing into the English-language discussion much of the wisdom from Latin American rural and forest communities' understandings of extractivist phenomena, and the destruction and changes in lives and lived environments they create. The author explores the many different types of extractivism, ranging from agro-extractivist monocultures to mineral extraction, and analyzes the differences between them. The existential transformations of Brazil's Amazon and Cerrado regions, previously inhabited by Indigenous people but now being deforested by colonizers who expand soybean plantations, are analyzed in detail. The author also compares extractivisms with the local and broader existential changes through global production networks and their shifts, produced by monoculture plantation-based extractivist operations. Anchored in the author's own ethnographic data and comparison of lessons across multiple extractivist frontiers, the chapters integrate the many accounts of violence, and onto-epistemic and moral changes in extractivist enclaves, looking at these with the help of political ontology. The book offers details on how to characterize and compare different types and degrees of extractivisms and anti-extractivisms. This transdisciplinary book provides new organizing concepts and theoretical frameworks for starting to analyze the unfolding natural resource politics of the post-coronavirus era, the advancing climate emergency, and the ever more chaotic multi-polar world. It will be of interest to students and scholars in the fields of international development, global value chains, political economy, Latin American Studies, political ecology, and international trade, as well as anyone engaged with the practical and political issues related to globalization"-- Provided by publisher.
