Indoor air quality and human health are of continuously growing importance. Indoor air quality may be affected by many factors excluding, but not limited to, more loosely sealed buildings, the use of air purifiers and other pollutant sources (for example, room air fresheners), the use of various chemicals for pesticide management and cleaning, and finally, the use of synthetic building materials and furnishings. In recent years, people have become more aware of potential health and comfort problems that may be associated with poor indoor air quality. It is partly due to the move to more tightly sealed buildings, the implementation of energy conservation programs, and the growing use of laser printers, photocopiers, and other sources of indoor air contamination. Greater general awareness of environmental issues may also play a part. Most IAQ complaints from building occupants are related to a respiratory headache, irritation, odours, or fatigue. These concerns may be associated with chemical vapours, dust generated in the work environment, contaminants associated with fungal growth (mould), materials infiltrating from outside sources (such as pollen or engine exhaust), or other factors such as elevated carbon dioxide levels. This handbook aims to turn the attention to these subjects and to promote methods and technologies to reduce poor indoor air quality and to distribute outdoor air throughout the building, remove contaminants and odours, and control the indoor temperature and humidity. The information in this guide will help to maintain good indoor air quality in a building, prevent indoor air quality problems, and correct issues that may arise. It will also help to understand the indoor air quality requirements. The structure of this text allows for flexibility in course content and design. It may be used equally well either as a textbook for students or a handbook for environmental consultants, mechanical engineers, building occupants, labour unions and suppliers. Furthermore, this text may be useful data for either the undergraduate or the graduate level.

Integrating information from several areas of engineering geology, hydrogeology, geotechnical engineering, this book addresses the general field of groundwater from an engineering perspective. It covers geological engineering as well as hydrogeological and environmental geological problems caused by groundwater engineering. It includes 10 chapters, i.e., basic groundwater theory, parameter calculation in hydrogeology, prevention of geological problem caused by groundwater, construction dewatering, wellpoint dewatering methods, dewatering wells and drilling, groundwater dewatering in foundation-pit engineering, groundwater engineering in bedrock areas, numerical simulation in groundwater engineering, groundwater corrosion on concrete and steel. Based on up-to-date literature, it describes recent developments and presents several case studies with examples and problems. It is an essential reference source for industrial and academic researchers working in the groundwater field and can also serve as lecture-based course material providing fundamental information and practical tools for both senior undergraduate and postgraduate students in fields of geology engineering, hydrogeology, geotechnical engineering or to conduct related research.

Cadmium Toxicity and Tolerance in Plants: From Physiology to Remediation presents a single research resource on the latest in cadmium toxicity and tolerance in plants. The book covers many important areas, including means of Cd reduction, from plant adaptation, including antioxidant defense, active excretion and chelation, to phytoextraction, rhizo filtration, phytodegradation, and much more. In addition, it explores important insights into the physiological and molecular mechanisms of Cd uptake and transport and presents options for improving resistance to Cd stresses. It will be ideal for both researchers and students working on cadmium pollution, plant responses and related fields of environmental contamination and toxicology.

What light does nearly twenty-five years of scientific study of the Exxon Valdez oil spill shed on the fate and effects of a spill? How can the results help in assessing future spills? How can ecological risks be assessed and quantified? In this, the first book on the effects of Exxon Valdez in fifteen years, scientists directly involved in studying the spill provide a comprehensive perspective on, and synthesis of, scientific information on long-term spill effects. The coverage is multidisciplinary, with chapters discussing a range of issues including effects on biota, successes and failures of post-spill studies and techniques, and areas of continued disagreement. An even-handed and critical examination of more than two decades of scientific study, this is an invaluable guide for studying future oil spills and, more broadly, for unraveling the consequences of any large environmental disruption.

This book is a systematic compilation of the most recent body of knowledge in the rapidly developing research area of greenhouse gas interaction with clay systems. Unexpected results of the most recent studies - such as unusually high sorption capacity and sorption hysteresis of swelling clays -stimulated theoretical activity in this fascinating field. Classical molecular dynamics (MD) explains swelling caused by intercalation of water molecules and to a certain degree of CO2 molecules in clay interlayer. However, unusual frequency shifts in the transient infrared fingerprints of the intercalated molecules and the following accelerated carbonation can be tackled only via quantum mechanical modeling. This book provides a streamlined (from simple to complex) guide to the most advanced research efforts in this field.

This book focuses on value addition to various waste streams, which include industrial waste, agricultural waste, and municipal solid and liquid waste. It addresses the utilization of waste to generate valuable products such as electricity, fuel, fertilizers, and chemicals, while placing special emphasis on environmental concerns and presenting a multidisciplinary approach for handling waste. Including chapters authored by prominent national and international experts, the book will be of interest to researchers, professionals and policymakers alike.

This book focuses on various aspects related to air pollution, including major sources of air pollution, measurement techniques, modeling studies and solution approaches to control. The book also presents case studies on measuring air pollution in major urban areas, such as Delhi, India. The book examines vehicles as a source of air pollution and addresses the quantitative analysis of engine exhaust emissions. Subsequent chapters discuss particulate matter from engines and coal-fired power plants as a major pollutant, as well as emission control techniques using various after treatment systems. The book's final chapter considers future perspectives and a way forward for sustainable development. It also discusses several emission control techniques that will gain relevance in the future, when stricter emission norms will be enforced for international combustion (IC) engines as well as power plants. Given its breadth of coverage, the book will benefit a wide variety of readers, including researchers, professionals, and policymakers.

This book offers a first-of-its-kind, standalone review of coalbed methane (CBM) in India, covering all the major technical and policy aspects. As an authoritative text on CBM in India, it addresses the essential geological, engineering and policy issues. The Coalbed Methane industry is a rapidly developing sector in Indian energy supply. The book presents the characteristics of coal beds in India's Damodar and Son river valleys, which influence the commercial viability of CBM in the regions, as well as a study of the gas contents of the country's major coalfields. The book begins with a brief review of methane emissions from Indian coal mines and the current coalbed methane situation in the country. Its unique features include a coalfield-by-coalfield technical assessment of CBM throughout India. Policy matters are addressed, including the National Exploration Licencing Policy (NELP) of the Indian Government Ministry of Petroleum and Natural Gas, which is vital to an overall understanding of CBM development in the country. The scope and depth of its book's coverage will benefit students, practising engineers, researchers and policy-makers.
