Impacts of Pollutants of Emerging Concern on Ecosystems and Human Health highlights the occurrence and the environmental and health risks of emerging contaminants. It covers the detection, source identification, and concentration of various emerging pollutants, such as pharmaceuticals, pesticides, and microplastics. This book delves into the transport, transformation, and bioaccumulation of these pollutants, analyzing their ecological and human health impacts. Additionally, it provides an overview of conventional and advanced treatment methods, presenting innovative, eco-friendly solutions for pollution control and remediation.Provides a comprehensive understanding of the occurrence of emerging pollutants in the environmentDescribes source tracking and the ecotoxicity threat posed by the emerging pollutantsDescribes the current obstacles in predicting the environment and human health risks of emerging pollutants

Explains the role of reactive intermediates in biological systems as well as in environmental remediationWith its clear and systematic approach, this book examined the broad range of reactive intermediate that can be generated in biological environments, detailing the fundamental properties of each reactive intermediate. Readers gain a contemporary understanding of how these intermediates react with different compounds, with an emphasis on amino acids, peptides, and proteins. The author not only sets forth the basic chemistry and nature of reactive intermediates, he also demonstrates how the properties of the intermediates presented in the book compare with each other.Oxidation of Amino Acids, Peptides, and Proteins begins with a discussion of radical and non-radical reactive species as well as an exploration of the significance of reactive species in the atmosphere, disinfection processes, and environmental remediation. Next, the book covers such topics as: Thermodynamics of amino acids and reactive species and the effect of metal-ligand binding in oxidation chemistryKinetics and mechanisms of reactive halogen, oxygen, nitrogen, carbon, sulfur and phosphate species as well as reactive high-valent Cr, Mn, and Fe speciesReactivity of the species with molecules of biological and environmental importanceGeneration of reactive species in the laboratory for kinetics studiesOxidation of amino acids, peptides, and proteins by permanganate, ferryl, and ferrate speciesApplication of reactive species in purifying water and treating wastewaterWith this book as their guide, readers will be able to assess the overall effects of reactive intermediates in biological environments. Moreover, they’ll learn how to apply this knowledge for successful water purification and wastewater treatment.

This book makes a serious effort at bringing forth and synergistically combining the concepts of green chemistry,sustainability and nanotechnology and should motivate scientistsat all levels to think clearly and seriously about creating and optimizing novel and sustainable green approaches to nanotechnology. The chapters in this book can be divided into three broad categories: 1) Advancement in research on pollution control through the green chemistry principles of nanotechnology; 2) Emergence of nanomaterials in widespread applications in various scientific fields, including but not limited to sensorsand catalysts; 3) Extension of research into nanotechnology and green nanotechnology at a rapid pace. Review articles on the individual aspects of these diverse and complementary topics have become important resources for researchers, industry leaders, and regulators, both nationally andinternationally. This book contains a few chapters associated with these particular themes, and provides glimpses of the many difficulties and challenges faced by those who seek to not only understand but also regulate the new nanomaterials. Nanotechnology represents a unique field of science, and necessitates new and novel sustainable approaches to create usable end products for the market place with the primary goal of yielding less adverse effects upon both human health and theenvironment.

This book is targeted for chemists and environmental scientists and engineers who are engaged in understanding the chemistry of high-valent iron (Ferrate) and in applications of chemical oxidants to treat contaminants in water, wastewater, and industrial effluents. This book will be of interested to biochemical engineers and microbiologists who want to understand ferrate's disinfection performance. Additionally, the book will be of tremendous interest to graduatestudents who are performing research on the understanding of the mechanism of higher oxidation states of iron and in developing innovative drinking water and wastewater treatment technologies. This book addresses synthesis and properties of Ferrate(VI), which is an environmentally friendly chemical for oxidation, coagulation, and disinfection for the multipurpose treatment of water and wastewater. It provides information on using different approaches to synthesize ferrate(VI). New processes to synthesize ferrate(VI) are detailed. Properties and generations of high oxidation states of iron including ferrate(IV) and ferrate(V) are discussed. Interestingly, possible formations of ironin unusual oxidation states, +7 and +8 are also discussed. The potential use of ferrate(VI) in high energy density rechargeable batteries is thoroughly reviewed. Chapters of the book demonstrate development of new technology for removing emerging pollutants without forming toxic side reactions orby-products. Examples include endocrine disruptors (EDs) and pharmaceuticals, which are of a great concern because of their possible toxic effects on humans and the ecology of the environment. Ferrate(VI) is an emerging water-treatment disinfectant, which can address the concerns raised by the currently used oxidants and disinfectants. Interestingly, ferrate(VI) does not react with the bromide ion; carcinogenic bromate ion would thus not be produced in the treatment of bromide-containing water.Ferrate(VI) can inactivate chlorine resistant bacteria. This book also provides information on the means to oxidize highly resistant organics and microorganisms in order to design appropriate remediation and water treatment technology which is cleaner and greener.
