This title includes a number of Open Access chapters. This new compendium volume examines the significant impact of air quality on human health. Assessing air pollution in complex morphologies has become an important issue in order to implement mitigation measures and limit emissions from the most relevant sources, such as waste incineration, traffic emissions, emissions from fuel and electricity production, and household emissions. These pollutants result in adverse health effects, material damage, damage to ecosystems, and global climate change. The book looks at these issues and is divided into several sections, covering air pollution and where we came from and where we're headed waste incineration and its impact on air quality air pollution vehicle and transportation emissions emissions from fuel and electricity production The chapters in Pollution and the Atmosphere: Designs for Reduced Emissions contain recent research looking at the two major components of air pollution: air pollution control and air-quality engineering. Air pollution control focuses on the fundamentals of air pollutant formation in process technologies and the identification of options for mitigating or preventing air pollutant emissions. Air quality engineering deals with large-scale, multi-source control strategies, with focus on the physics and chemistry of pollutant interactions in the atmosphere.
Unique problem-and-solution approach for quickly mastering a broad range of calculations This book's problem-and-solution approach enables readers to quickly grasp the fundamentals of air pollution control equipment and essential applications. Moreover, the author sets forth solid principles for the design and selection of air pollution control equipment as well as for its efficient operation and maintenance. Readers gain a deep understanding of both the equipment itself and the many factors affecting performance. Following two introductory chapters, the book dedicates four chapters to examining control equipment for gaseous pollutants, including adsorption, absorption, and incineration equipment. The remaining six chapters deal with equipment for managing airborne particulate pollutants, including gravity settlers, cyclones, electrostatic precipitators, scrubbers, and baghouses. The appendix contains discussions of hybrid systems, the SI system (including conversion constants), and a cost-equipment model. Each chapter offers a short introduction to the control device discussed. Next, progressively more difficult problems with accompanying solutions enable readers to build their knowledge as they advance through the chapter. Problems reflect the most recent developments in pollution control and include a variety of performance equations and operation and maintenance calculations. Each problem includes a statement of the problem, the data used to solve the problem, and a detailed solution. Readers may further hone their skills by visiting the text's Web site for additional problems and solutions. This publication serves both as a textbook for engineering students and as a reference for engineers and technicians who need to ensure that air pollution control equipment operates efficiently and enables their facility to meet all air pollution control standards and regulations.

Since 2009, the U.S. Environmental Protection Agency (EPA) has proposed and promulgated numerous regulations to implement the pollution control statutes enacted by Congress. Critics have reacted strongly. Some, both within Congress and outside of it, have accused the agency of reaching beyond the authority given it by Congress and ignoring or underestimating the costs and economic impacts and overestimating the benefits of proposed and promulgated rules.

Energy demand in the United States is expected to continue to grow over the coming decades, and the Department of Energy (DOE) considers nuclear energy to be one way to help meet this increased demand without producing air pollution. However, the current domestic commercial nuclear reactor fleet, consisting of 99 large light water reactors (LWRs) that provide about 20 percent of U.S. electricity is aging, and some reactors have shut down in recent years. LWRs use light, or ordinary, water to cool the reactor. New reactor concepts are under development as alternative energy options. Light water small modular reactors (SMRs) have some similarities, including the coolant used, to the existing large LWRs, and advanced reactors differ more from the large LWRs. Both new reactor concepts differ from the existing large LWRs in potential applications. This book discusses the status of light water SMR and advanced reactor concepts under development; the intended benefits of these new reactor concepts; and the challenges associated with developing and deploying these new types of reactors. Furthermore, the book describes DOE's Office of Nuclear Energy's (NE) approach to advanced nuclear reactor research and development (R&D) and examines how NE plans and prioritises its advanced reactor R&D activities, including deploying an advanced reactor.
In recent decades, it has been recognized that environmental pollution causes serious local and global harmful effects, both to human health and ecosystems, and therefore the protection and restoration of the environment is a matter of great importance. Through the joint efforts of mathematicians, geophysicists and environmentalists, diverse methods for solving varied problems of environmental pollution have been developed. In this text, mathematical methods for analyzing the problems of transport and dispersion of relatively passive pollutants, control of air emissions and remediation of polluted aquatic systems are presented in such form that they are easily understood by undergraduate and graduate students. The application of the adjoint method is emphasized as a way to get dual estimates of average concentrations of different substances. This methodology helps to establish simple variational and linear programming formulations in order to calculate optimal solutions of these problems in the sense that they meet the standards of air quality and cause the minimal variations in the industrial processes or in the environment. This text is primarily intended for scientists, engineers and other professionals working in the field of environmental modeling (transport of air and water pollutants, assessment of pollution levels, optimal control of emission rates from point, line and area sources, the optimal location of a new industrial plant, bioremediation of oil-contaminated aquatic zones, etc.). We hope that this book will be useful for undergraduate and graduate students of engineering sciences and earth sciences as well.
Il volume approfondisce il complesso tema dei rapporti tra vegetazione e inquinanti dell'aria, affrontandone in modo capillare e ben documentato sia gli aspetti scientifici sia le implicazioni storico-culturali. Dopo una rassegna delle sorgenti di inquinanti, vengono analizzate le risposte di tipo fisiologico, metabolico, ecologico ed economico delle piante agrarie e forestali ai principali inquinanti gassosi e particellari, tra i quali l'ozono e di gran lunga il problema numero uno a livello mondiale. Ugualmente trattati sono i meccanismi di veicolamento da parte delle piante di elementi potenzialmente tossici (per esempio, metalli pesanti e radionuclidi) nella catena alimentare e anche le possibili conseguenze sugli animali e sulla salute umana. La ricca iconografia a colori, l'approccio didattico, gli aggiornamenti normativi nazionali e comunitari, cosi come la dettagliata trattazione di tematiche quali la fitotossicologia, l'ecologia, la patologia vegetale, il biomonitoraggio, l'educazione ambientale e la valutazione di impatto ambientale, rendono il testo un sussidio indispensabile per i laureandi e gli specializzandi nelle Facolta di Agraria e di Scienze Biologiche, Ambientali e Naturali, per i tecnici e per tutti i professionisti e gli operatori che necessitano di una conoscenza completa dell'argomento.
Pesticides used to control weeds, unwanted insects, and fungi contribute to agricultural productivity and public health by preventing crop damage and controlling pests. However, pesticides may also have adverse effects. EPA's OPP reviews applications for pesticide products and registers those that it determines do not have unreasonable adverse effects on health and the environment. This book examines the extent to which EPA inspects for GLP compliance laboratories that test pesticides and the challenges EPA faces in doing so; uses the information obtained through GLP inspections in its pesticide decision-making process; and collaborates with FDA on GLP inspections.
Concerns for fuel economy and reduced emissions have turned the attention of automotive internal combustion engine manufacturers to the exhaust system and towards technological system development to account for the significant levels of potential energy that can be recovered. The present volume on "Automotive Exhaust Emissions and Energy Recovery" for both gasoline and diesel engines is therefore both timely and appropriate. Whereas diesel engines have been predominantly turbocharged, only a relatively small percentage of gasoline engines are similarly equipped, which has led to significant efforts by engine manufacturers in recent years to downsize and down-speed these engines. On the other hand, the relative focus in diesel engine development in terms of emissions and exhaust energy recovery has shifted toward devices other than the turbocharger for enhanced energy recovery and emissions control technologies in order to allow the diesel engines of the future to keep up with the dual-demand for very low emissions and increasing levels of fuel economy. The book focuses on the exhaust system and the technologies and methods used to reduce emissions and increase fuel economy by capitalising on the exhaust gas energy availability (either in the form of gas kinetic energy or as waste heat extracted from the exhaust gas). It is projected that in the short to medium term, advances in exhaust emissions and energy recovery technologies will lead the way in internal combustion engine development and pave the way towards increasing levels of engine hybridisation until fully electric vehicle technology can claim a level of maturity and corresponding market shares to turn the bulk of this focus away from the internal combustion engine. This book is aimed at engine research professionals in the industry and academia, but also towards students of powertrain engineering. The collection of articles in this book reviews the fundamentals of relevance, recent exhaust system technologies, details recent or on-going projects and uncovers future research directions and potentials.
Petroleum perhaps is one of the most important substances in the modern society due to its wide use in the most diverse productive sectors. Besides serving as raw material to the production of plastics and other compounds, it is the fuel source used in the production of electric energy, in industries and in different transport sectors. However, the ecosystems located in areas of extractions, processing and distribution of petroleum end up being highly susceptible to the direct and indirect impacts of these activities, as well as those located in their transport route. As the large extraction fields are located in coastal areas, these environments are, generally, the most affected, although other ecosystems also suffer influence of petroleum activities. Oil spills and leakages provoke immediate effects into the environment, easily viewed by the generalized mortality of animals and consequent ecosystems losses, but also provoke more persistent effects, such as alteration of the animals behaviour and permanence of compounds derived from petroleum in the food webs. Accidents with petroleum are unpredictable and the resources needed to minimize their impacts, often, are not liable to an immediate application. This book discusses different prevention methods as well as environmental and ecological impacts oil spills have.
Despite the fact that water covers two-thirds of the Earth's surface, it is surprisingly vulnerable to human influence and activity. Marine ecosystems receive large amounts of a variety of pollutants from either treated or untreated wastewater. The extensive use of chemicals and their introduction into the environment has resulted in increased public concern for the potential threats to ecosystems, human health and safety. Persistent organic pollutants such as polychlorinated biphenyls, polycyclic aromatic hydrocarbons, polybrominated diphenyl ethers and pesticides, as well as heavy metals, surfactants; endocrine disrupting chemicals or personal care products and pharmaceuticals are pollutants usually present in marine environments. This book focuses on discussing the types of marine pollutants. It provides topics on the environmental significance and management strategies available.
This book is a compilation of research on oil spills in ice-covered Arctic waters and recommendations for future work. Research entities in governmental, nongovernmental, industrial, and private organizations are identified. An introduction to the topic is provided. In this book, the U.S. Arctic Research Commission (USARC) recommended to the federal government an invigorated oil spill research effort in the Arctic and a funding strategy that did not require new fiscal appropriation. Considering the potential for increased energy exploration and production in deeper, offshore waters, as well as an anticipated escalation in shipping in a rapidly evolving marine environment, the risks of oil spills remain a real and growing challenge. In developing these recommendations, USARC worked closely with the federal Interagency Coordinating Committee on Oil Pollution Research (ICCOPR), stakeholders, and the public.
Greenhouse gas emissions have increased markedly since the pre-industrial era and are increasing at such a rate that their concentration in the atmosphere is producing a warming influence on the global climate. In order to make well-informed decisions on ways to reduce greenhouse gas emissions, it is important to understand how the different economic sectors contribute to the production of greenhouse gases, which sectors are relatively carbon dioxide (CO2) intensive, and how these patterns have evolved over time. This book analyses energy-related CO2 emissions and intensities for 349 industries, Government (Federal, state and local), and Households. The 349 industries cover the entire economy, providing information on detailed sub-sectors within the aggregate sectors of Agriculture, Forestry and Fisheries, Mining, Construction, Manufacturing, Transportation Services, and all other services.
The term ecotoxicology is the branch of toxicology concerned with the study of toxic effects, caused by natural or synthetic pollutants, to the constituents of ecosystems, animal (including human), vegetable and microbial. This book discusses the ecotoxicological effects of pharmaceuticals in the environment; the effects of various ecotoxicants on nematodes; salinity threats to agricultural productivity; sorption and the ecological risk assessment of non-ionic organic contaminants; and the application of ecotoxicological tools in the assessment, monitoring of Brazilian waters; and others.
Fly ash is one of the residues generated in the combustion of coal. Fly ash is generally captured from the chimneys of coal-fired power plants, and is one of two types of ash that jointly are known as coal ash; the other, bottom ash, is removed from the bottom of coal furnaces. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline) and calcium oxide (CaO). Toxic constituents include arsenic, beryllium, boron, cadmium, chromium, chromium VI, cobalt, lead, manganese, mercury, molybdenum, selenium, strontium, thallium, and vanadium, along with dioxins and PAH compounds. In the past, fly ash was generally released into the atmosphere, but pollution control equipment mandated in recent decades now require that it be captured prior to release. In the US, fly ash is generally stored at coal power plants or placed in landfills. About 43 percent is recycled, often used to supplement Portland cement in concrete production. It is increasingly finding use in the synthesis of geopolymers and zeolites.
This new book is devoted to leading-edge research on environmental biodegradation which is the destruction of organic compounds by microorganisms. Microorganisms, particularly bacteria, are responsible for the decomposition of both natural and synthetic organic compounds in nature. Mineralisation results in complete conversion of a compound to its inorganic mineral constituents (for example, carbon dioxide from carbon, sulphate or sulphide from organic sulphur, nitrate or ammonium from organic nitrogen, phosphate from organophosphates, or chloride from organochlorine). Since carbon comprises the greatest mass of organic compounds, mineralisation can be considered in terms of CO2 evolution. Radioactive carbon-14 (14C) isotopes enable scientists to distinguish between mineralisation arising from contaminants and soil organic matter. However, mineralisation of any compound is never 100% because some of it (10-40% of the total amount degraded) is incorporated into the cell mass or products that become part of the amorphous soil organic matter, commonly referred to as humus. Thus, biodegradation comprises mineralisation and conversion to innocuous products, namely biomass and humus. Primary biodegradation is more limited in scope and refers to the disappearance of the compound as a result of its biotransformation to another product. Compounds that are readily biodegradable are generally utilised as growth substrates by single microorganisms. Many of the components of petroleum products (and frequent ground-water contaminants), such as benzene, toluene, ethylbenzene, and xylene, are utilised by many genera of bacteria as sole carbon sources for growth and energy.
Hazardous waste is a waste with properties that make it dangerous or potentially harmful to human health or the environment. Hazardous waste generally exhibits one or more of these characteristics: ignitability, corrosivity, reactivity or toxicity. The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sludges. They can be the by-products of manufacturing processes or simply discarded commercial products, like cleaning fluids or pesticides. One major type is radioactive waste. This book brings together the latest research in this diverse field.
Time-activity diaries kept by members of the general public indicate that on average people spend around 90% of their time indoors, this is associated with considerable exposure to air pollutants as not only is there infiltration of pollutants from outdoors, there are also emissions indoors that can lead to elevated pollutant concentrations. Despite this, and the fact that the WHO produces air quality guidelines for indoor air, the only statutory requirements for monitoring of airborne pollutant concentrations relate to the outdoor environment. Given its importance as a source of air pollution exposure, increasing attention is being given to pollution of the indoor environment. This volume considers both chemical and biological pollutants in the indoor atmosphere from their sources to chemical and physical transformations, human exposure and potential effects on human health. It is a valuable reference for those working in in environmental policy, civil and environmental engineering as well as for atmospheric chemists.
Starting with the 2010 Gulf of Mexico Deepwater Horizon oil spill incident, Oil Spill Impacts: Taxonomic and Ontological Approaches chronicles a timeline of events that focus on the impact of oil spills and provides an understanding of these incidents using a number of approaches. The book includes an interdisciplinary oil spill taxonomy, an oil spill topic map, and highlights information-organization tools, such as indexes, taxonomies, and topic maps that can be used to connect information resources with concepts of interest. The topic map combines the function of ontology with the function of organized information resources, and contains thousands of concepts and their relationships extracted from approximately 300 documents stemming from various academic conference presentations, journal articles, news reports, and web pages. Divided into four parts, the book begins with a brief introduction of the Gulf of Mexico Deepwater Horizon oil spill events followed by a breakdown of the taxonomy concepts distributed into categories and their subcategories. The book then describes the oil spill topic map separated by concepts, relationships, and references. This interdisciplinary reference provides to its readers: The perspective of multiple disciplines instead of just one discipline An indication of the most important topics in the oil spill domain Developed research in the oil spill and oil drilling areas A broad and detailed view of oil spill issues The book serves students, teachers, and researchers interested in oil spill issues, oil spill incidents, and addresses their impacts that involve coastal and marine environmental sciences, biological sciences, chemistry, disaster management, geology, sociology, and government policy. |
