Book Description
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. The chapter "Mechanochemical Forces as a Synthetic Tool for Zero and One-Dimensional Titanium Oxide-Based Nano-photocatalysts" is available open access under a CC BY 4.0 License via link.springer.com.

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
Globally, 2.1 billion people live without access to safe water, and about 159 million people collect their drinking water directly from surface water sources. This issue is particularly prominent in water-stressed areas, such as India, which has a rural population of around 700 million, 63 million of whom do not have access to clean water. Contaminants of Emerging Concern (CECs), of both a chemical and biological nature, are increasingly being detected in wastewater effluents around the world. Chemical CECs include pollutants such as pharmaceuticals and personal care products, pesticides, hormones, and endocrine disruptors, and biological CECs include antibiotic resistant bacteria, pathogenic protozoans, and viruses. New technologies to remove the contaminants from water are urgently needed and photochemical approaches offer an exciting array of possibilities. Covering chemical analysis, molecular biology methods and computational approaches important for the elucidation of mechanisms and evaluation of photochemical processes, this book presents advanced photochemical processes for the removal of CECs from water. Readers will find chapters on advanced photochemical treatment prototypes and pilot plants, and discussions on translation from lab to field-scale implementation. Examples include highly transparent materials, integrated membranes, adsorbents, and photocatalysts for enhancing the photochemical processes by direct sunlight induced reactions, photo-Fenton, and photo-electrochemical reactions. Discussing both the advantages and disadvantages of these technologies, this book is a great resource both for academics researching photocatalytic processes and for water treatment professionals.
