"Reflecting current health concerns, the book also addresses such timely issues as oxidative stress and asbestos, the role of oxygen in lung toxicity induced by mineral fibers and particulates, as well as an alternative attainment criteria for a secondary federal standard for ozone. A selective and incisive look at the current state of research on oxidants, Environmental Oxidants provides environmental scientists and engineers with an informative, detailed discussion of just how and why oxidants have emerged as a key issue in human health and environmental integrity."--Jacket.

Advanced oxidation processes (AOPs) use chemical treatment to remove contaminants from water by oxidation with hydroxyl radicals. These hydroxyl radicals can be produced using UV light, ozone or hydrogen peroxide, but recently reactions have been developed that use persulfates as the radical source. Persulfates are strong oxidants with flexible in situ activation characteristics, including activation with heat, alkali conditions, electricity, ultrasonic treatment, transition metals, carbon and even organics. Persulfate activation can generate sulfate radicals as well as other reactive species. These reactive species, especially the sulfate radical, can degrade most organic pollutants making them valuable in the fields of water purification, soil remediation, disinfection, sludge dewatering, and other important applications in environmental systems. Describing recent developments in persulfate-based AOPs, this book aims to provide a summary of environmental applications for persulfate-based AOPs and to guide the reader, in a comprehensive way, through various advanced oxidation processes in environmental applications. Topics include new activation methods, activation mechanisms, and advanced materials for use in activating persulfate-based AOPs for different environmental applications.

Photochemical oxidants are secondary air pollutants formed under the influence of sunlight by complex photochemical reactions in air which contains nitrogen oxides and reactive hydrocarbons as precursors. The most adverse components formed by photochemical reactions in polluted air are ozone (0 ) 3 and peroxyacetyl nitrate (PAN), among many other products such as aldehydes, ketones, organic and inorganic acids, nitrates, sulfates etc. An analysis and evaluation of the available knowledge has been used to characterize the relationships among emissions, ambient air concentrations, and effects, and to identify the important controlling influences on the formation and effects of photochemical oxidants. The biological activity of photochemical oxidants was first clearly manifested during the early 1940's, when vegetation injury was observed in the Los Angeles Basin in the United States. Since that time, as a consequence of the increasing emissions of photochemical oxidant precursors, the photochemical oxidants have become the most important air pollutants in North America. In other parts of the world, for example South and Central America, Asia, and Australia, photo chemical oxidants threaten vegetation, particularly the economic and ecological performance of plant life. According to my knowledge, the first observations of ozone and PAN injury to vegetation in Europe were made by Dr. Ellis F. Darley (Statewide Air Pollution Research Center, University of California, Riverside, California) during a study visit (1963/64) to the Federal Republic of Germany.

Advanced Oxidation Technologies (AOTs) or Processes (AOPs) are relatively new and innovative technologies to remove harmful and toxic pollutants. The most important processes among them are those using light, such as UVC/H2O2, photo-Fenton and heterogeneous photocatalysis with TiO2. These technologies are also relatively low-cost and therefore useful for countries under development, where the economical resources are scarcer than in developed countries. This book provides a state-of-the-art overview on environmental applications of Advanced Oxidation Technologies (AOTs) as sustainable, low-cost and low-energy consuming treatments for water, air, and soil. It includes information on innovative research and development on TiO2 photocatalytic redox processes, Fenton, Photo-Fenton processes, zerovalent iron technology, and others, highlighting possible applications of AOTs in both developing and industrialized countries around the world in the framework of “A crosscutting and comprehensive look at environmental problems”. The book is aimed at professionals and academics worldwide, working in the areas of water resources, water supply, environmental protection, and will be a useful information source for decision and policy makers and other stakeholders working on solutions for environmental problems.

From a symposium at the 204th National Meeting of the American Chemical Society, Washington, D.C., August 1992. The research in this area is motivated by the locally severe environmental impacts and toxicity associated with the products of sulfide oxidation. Thirty- nine multidisciplinary papers address various aspects of sulfide oxidation: laboratory studies of kinetics; numerical modeling in tailings, waste rock, and in situ deposits; solubility and sorption control in formation of sulfide-oxidation products; transport products in surface waters, and in sediments; effects on ground-water geochemistry; processes in wetlands and the oceans; analytical methods; and remediation and prevention of environmental effects.
