Ground water reactive transport models are useful to assess and quantify contaminant precipitation, absorption and migration in subsurface media. Many ground water reactive transport models available today are characterized by varying complexities, strengths, and weaknesses. Selecting accurate, efficient models can be a challenging task. This ebook addresses the needs, issues and challenges relevant to selecting a ground water reactive transport model to evaluate natural attenuation and alternative remediation schemes. It should serve as a handy guide for water resource managers seeking to achieve economically feasible results.

Hazardous Waste Management and Health Risks presents a systematic overview of evaluating solid and hazardous waste management practices. The book introduces readers to the basic principles of hazardous waste management and progresses into related topics that allow managers to assess environmental quality. These topics include heavy metal pollution, reproductive biomarkers as signals of environmental pressure and health risks, and environmental contamination in an international perspective. With an emphasis on sustainable development throughout the text, a zero-waste strategy as an alternative way to manage hazardous waste is suggested in a dedicated chapter. This reference book is intended as an introductory guide for managers taking waste management training courses and students involved in degree courses related to environmental engineering and management.

Mechanisms of Landscape Rehabilitation and Sustainability is based on the results of landscape rehabilitation with the help of fabricated soil and a new approach on the use of restored soils for building houses and communities. This book presents discoveries and proposals that have emerged from the authors' research and explains ways to protect Earth's ecosystems against further degradation. These proposals are founded on the philosophy of sustainable development and its application to various aspects essential to the long-term success of human beings; these include community coexistence, education, water purification and recycling, agriculture, the production of fabricated soil for landscape rehabilitation, and the preservation and propagation of wild flora. Strategies for both indoor and outdoor systems are covered in this publication. The book covers several subjects including molecular biology, botany, microbiology, soil biochemistry and human interaction with the ecosystem. Methods for soil rehabilitation ultimately allow us to obtain optimal crop yield. Mechanisms of Landscape Rehabilitation and Sustainability is of particular interest to academic and professional biologists, soil scientists, ecologists, agronomists and architects.

Nitrogen containing compounds produced by industrial processes are pollutants which pose a significant environmental and health hazard. There are a number of processes that have been devised for removing nitrogen compounds from wastewater. This reference book summarizes different denitrification methods for wastewater processing. The book introduces readers to toxic nitrogen compounds responsible for water pollution. This introduction is followed by chapters which explain different nitrogen removal methods including conventional methods, biological methods, food industry wastewater treatment and new approaches towards environmental pollution remediation: Bio Electrochemical Systems (BESs). This book is a handy reference guide for industrial and environmental engineers and students learning about wastewater management and industrial denitrification.

Although a lot is known about the influence of Polycyclic Aromatic Hydrocarbons (PAHs) on the marine environment, there are still many unanswered questions. Petrogenic Polycyclic Aromatic Hydrocarbons in the Aquatic Environment is a monograph that sums up basic knowledge about this topic while highlighting current research practices useful in studying the aquatic environment. It starts with an introduction to effect of PAH in the marine environment. It then proceeds to provide information on techniques to monitor PAH levels and investigate the affected environment in order to control the subsequent negative effects. Chapters also detail the carcinogenic and endocrine effects of PAHs on fish as well as the degradation of PAHs by microorganisms. This monograph is a useful reference for environmental science students and professionals learning about the role of PAH in the marine environment.

Photographs Across Time: Studies in Urban Landscapes presents a record of urban environments in Britain, including Oxford, York, Scarborough, Dunbar, Edinburgh, and Inverness. It is a unique demonstration of how digital photography bridges urban landscape studies with archaeology and heritage studies. The book revisits several landscape and weathering studies in churchyards throughout England and Scotland in the UK. The book explains cross temporal and archival applications of digital photography and explores the archaeological use of photographs. Readers can also learn about issues related to creating and maintaining digital records as well as issues relevant to heritage sustainability. Researchers, landscape experts and professional photographers as well archivists will find Photographs Across Time as a handy reference for quantitative geomorphological studies on English heritage sites and the qualitative realm of historical archaeology.

Discussions on historical and philosophical issues in ecology have been rather limited. This volume presents an enriched and comprehensive review on ecological issues. The topics covered in this e-book include the emergence of the field of life-history strategies in population ecology, the model building tradition in community ecology, the holism/reductionism debate, the ecosystemic and systemic approach as well as a discussion of the emergence, development and dominance of the biodiversity concept. By bringing together diverse ideas, points of view and theoretical traditions, often treated separately, the book allows the development of ecology as a whole discipline to emerge. This introductory book is intended to stimulate discussion among both beginners and professionals in the field of history and/or philosophy of science, as well as ecologists. The topics covered are also central to the concerns of scholars engaged in environmental studies, environmental ethics and policy-making.

This reference presents reviews and case studies of hazardous waste management in a selection of cities. The overarching themes of the compiled topics include 1) the problems of healthcare waste management, 2) case studies of hazardous waste mismanagement, 3) health risks associated with environmental waste, issues in environmental health and 4) grassroots environmentalism. The volume initially presents reviews and case studies from developing countries, including countries in South America (Argentina), Africa (Algeria and Nigeria), and Asia (India). The latter chapters of the book focus on environmental issues in Campania, a region in Italy. These chapters also provide an insight into the impact of the COVID-19 pandemic on waste management practices in this region. Risks and Challenges of Hazardous Waste Management is an insightful reference for management trainees, professionals and researchers associated with waste management and environmental health firms. Readers will gain insights into current issues and practices in the respective industries. The reviews and case studies presented in the reference are also useful to professionals involved in risk assessment studies.

The removal of contaminants and pollutants from natural or valuable materials is a critical issue in environmental management and conservation. Fundamentally, the procedure consists of measures employed to separate what is good (recyclable materials, soil and sediments) from what is bad (non recyclable materials, contaminants). A perspective of current technologies developed for mineral processing is of great assistance for finding appropriate solutions for different environmental situations. The liberation and separation processes adopted to recover valuable minerals from a gangue are, in principle, the same processes that can be applied to waste materials for recovering useful materials and to soil and sediments to reduce contamination. Separating Pro-Environment Technologies for Waste Treatment, Soil and Sediments Remediation investigates how technologies for separation, that take origin form mineral processing, have improved and evolved when applied to waste treatment and soil and sediment remediation.
