Book Description
With an increased demand for wastewater reuse, groundwater recharge with treated wastewater has been practiced across the globe. As a result, groundwater quality deteriorates by emerging micropollutants from various anthropogenic origins, including untreated wastewater, seepage of landfill leachate, and runoff from agricultural lands. The fate of such emerging and geogenic contaminants in subsurface systems, especially in the groundwater, depends on several factors. Physicochemical properties of contaminants such as octanol-water partition coefficient, dissociation constant, water solubility, susceptibility to biodegradation under anaerobic conditions, and environmental persistence under diverse geological and pH conditions play a critical role during subsurface mass flow. Thus, advanced wastewater treatment techniques, followed by implementing stricter guidelines, are some of the measures that can safeguard water resources. This book, in general, gives an understanding of the fate and mitigation strategies for emerging and geogenic contaminants in the groundwater. The first and second sections provide a detailed insight into various removal techniques and mitigation approaches. Possible treatment strategies, including bioremediation and natural attenuation, are also covered in those sections. Environmental assessment, groundwater vulnerability, health effects, and regulations pertaining to various contaminants are systematically presented in the third section.

Book Description
This volume takes a multidisciplinary approach to study and evaluate the global human vulnerability to the exposure of contaminants of emerging concern (CECs) in the natural environment. It provides a comprehensive resource on structurally diverse groups of chemical compounds that have adverse effects on the aquatic environment. It explores the global strength, environmental status, chemical risk assessment and management strategies of CECs with relevant modern techniques. The principle focus is on concurrent emerging water quality issues. It defines the impacts of the environmental exposure of trace concentrations of CECs and/or their metabolites and discusses possible technological advances to combat the emerging pollutants. It will be useful to researchers, multi-stakeholder expert groups, policymakers, and graduate students.

Book Description
Emerging Aquatic Contaminants: One Health Framework for Risk Assessment and Remediation in the Post COVID-19 Anthropocene highlights various sources and pathways of emerging contamination, including their distribution, occurrence, and fate in the aquatic environment. The book provides detailed insight into emerging contaminants' mass flow and behavior in various spheres of the subsurface environment. Possible treatment strategies, including bioremediation and natural attenuation, are discussed. Ecotoxicity, relative environmental risk, human health risk, and current policies, guidelines, and regulations on emerging contaminants are analyzed. This book serves as a pillar for future studies, with the aim of bio-physical remediation and natural attenuation of biotic and abiotic pollution. - Includes real-world applications and case studies to show how these practices can be adopted - Presents global coverage, with a diverse list of contributors, all of whom are experts in the field - Uses illustrative diagrams to provide a clear and foundational understating of the topics

Book Description
In the last years the release of emerging pollutants such as Endocrine Disruptors (EDCs), Pharmaceuticals and Personal Care Products (PPCPs) into the environment has raised great concern. While investigating how to treat emerging pollutants from water and wastewater, researchers have drawn attention on the implementation of more environmentally friendly technologies able to achieve high removal efficiency at low costs. Emerging Compounds Removal from Wastewater by Green Technologies: Natural and Solar Based Treatments introduces green chemistry in relation to these treatment technologies. More specifically, this volume: • Reviews the suitability of alternative adsorption processes that use natural adsorbents natural materials or agricultural waste in light of the inefficiency of conventional wastewater treatment plants; • Evaluates the potential of constructed wetlands for the removal of some categories of trace contaminant of worldwide relevance in view of their application as decentralized systems; • Highlights the promising role of a special class of oxidation techniques defined as Advanced Oxidation Processes (AOPs) supported by sunlight. This volume will be of great interest to students, technicians, and academics alike who are interested in evaluating and selecting the technologies that lead to better and more sustainable treatment of this huge class of pollutants.

Book Description
This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
