World water resources seem to be abundant; however, only 0.7% of this total amount is usable water. And owing to their nonuniform distribution, some countries have abundant water resources, whereas some others suffer from inadequate water, and even face severe water scarcity problems. Moreover, serious water pollution problems make 1/5 of the world’s population (approximately 1.1 billion people) under the risk of water-related diseases. In order to give a guideline to maintain the required quality of water according to the intended use, a group of international experts have come together to write this book. Authors target to pass recent available knowledge and information to the readers, who will vary from academicians, professional engineers and scientists, to undergraduate and graduate engineering students concerned with water quality problems all over the world. This book covers the main fields of Wastewater Treatment with 12 chapters, and uses knowledges in economic, information technologies, biology, etc. to make comprehensive analyses and applications.
Since 1988, there has been much literature published on the chemistry of nitric oxide, particularly in the field of S-nitrosation and the chemistry of S-nitroso compounds. Written by a chemist for the chemistry community, this book provides an update of the chemistry of nitrosation reactions, dealing with both the synthetic and mechanistic aspects of these reactions. It also looks at the chemistry of nitric oxide in relation to the amazing biological properties of this simple diatomic molecule, which were unknown until around 1990. * Provides an update on previously published literature on nitric oxide chemistry* Contains chapters on reagents for nitrosation, nitrosation at nitrogen, aliphatic and aromatic carbon, oxygen, sulfur and metal centres* Looks at hot research topics such as synthesis, properties and reactions of s-nitrosothiols
Constant media attention on oil spills has created global awareness of their risks and the damage they do. Often under-reported is the average cost of the cleanup - often as high as $200 per liter of oil spilled. Oil is a necessity in today's industrial society, and since our dependence on it is not likely to and any time soon, we will continue to
Volume is indexed by Thomson Reuters CPCI-S (WoS). Collection of selected, peer reviewed papers from the 2013 2nd Global Conference on Civil, Structural and Environmental Engineering (GCCSEE 2013), September 28-29, 2013, Shenzhen, China.

Investigates the compound formation, bioactivation, and detoxification of the N-nitroso group of compounds, which increasingly appears to be implicated in human carcinogenesis. The topics include exposure, formation, and blocking; nitric oxide; nitrosamine; toxic, mutagenic, and carcinogenic effects; and reactive intermediates. The 45 papers largely report on research rather than review the literature. The symposium that occasioned them was in Washington, DC, in August 1992.

Surveillance for waterborne disease and outbreaks associated with drinking water and water not intended for drinking-- United States, 2005-2006: "Problem/Condition: Since 1971, CDC, the U.S. Environmental Protection Agency (EPA), and the Council of State and Territorial Epidemiologists have maintained a collaborative Waterborne Disease and Outbreak Surveillance System (WBDOSS) for collecting and reporting data related to occurrences and causes of waterborne-disease outbreaks (WBDOs) and cases of waterborne disease. This surveillance system is the primary source of data concerning the scope and effects of waterborne disease in the United States. Reporting Period: Data presented summarize 28 W...
In 1982 the International Association on Water Pollution Research and Control (IAWPRC), as it was then called, established a Task Group on Mathematical Modelling for Design and Operation of Activated Sludge Processes. The aim of the Task Group was to create a common platform that could be used for the future development of models for COD and N removal with a minimum of complexity. As the collaborative result of the work of several modelling groups, the Activated Sludge Model No. 1 (ASM1) was published in 1987, exactly 25 years ago. The ASM1 can be considered as the reference model, since this model triggered the general acceptance of wastewater treatment modelling, first in the research comm...
