Book Description
Drinking water quality has been a matter of concern for several decades. Disinfection of drinking water improves its microbiological quality and prevents disease outbreaks. However, continuously increasing scientific research concerns the presence of organic and inorganic contaminants in water. Many of these compounds, named haloforms, originate from the procedure of disinfection, being formed during reactions of disinfectants with natural organic matter present in water. Haloforms may possess carcinogenic or mutagenic properties; therefore minimization of their concentrations in drinking water is a critical issue. Regulatory measures are becoming more and more stringent, as new health effects become known and optimized high-sensitivity analytical methodologies are being developed. Up-to-date research findings concerning all these aspects have been collected, critically reviewed, summarized, and are presented and discussed in the present book.

Book Description
Disinfection By-Products in Water Treatment describes new government regulations related to disinfection by-products. It explains the formation of microorganism by-products during water treatment and the methods employed to control them. The book includes several chapters on chlorine by-products and discusses techniques for the removal of chloroform from drinking water. It also describes gamma radiation techniques for removing microorganic by-product precursors from natural waters and the removal of bromate from drinking water.

Book Description
For the last decade, concern over drinking water safety has rapidly increased. Revelations of chemical contamination of surface and ground waters, and the realization that drinking water treatment by traditional methods such as chlorination may introduce unforeseen new problems, has focused the attention of the public as well as the research community on these issues. Crossing disciplines, this timely new book addresses the whole issue, combining the expertise of specialists in engineering, biology and chemistry. An ACS Environmental Chemistry Division Symposium book.

Book Description
This volume of the IARC Monographs provides an assessment of the carcinogenicity of 18 chemicals present in industrial and consumer products or food (natural constituents, contaminants, or flavorings) or occurring as water-chlorination by-products. The compounds evaluated include the widely used plasticizer di(2-ethylhexyl) phthalate and the food contaminant 4-methylimidazole. In view of the limited agent-specific information available from epidemiological studies, the IARC Monographs Working Group relied mainly on carcinogenicity bioassays, and mechanistic and other relevant data to evaluate the carcinogenic hazards to humans exposed to these agents.

Book Description
Evaluates the carcinogenic risk to humans posed by the consumption of chlorinated drinking-water by two chemicals used in the chlorination of drinking-water by a number of halogenated by-products formed when chlorine interacts with organic matter in water and by a selection of other halogenated compounds found in drinking-water. Chlorination was selected for evaluation because of its widespread use and because potentially carcinogenic by-products have been measured in chlorinated water. The book also includes a separate monograph on cobalt and cobalt compounds. The volume opens with a discussion of the many methodological problems that complicate efforts to assess the carcinogenicity of chlorinated water. Against this background the book evaluates the design and findings of all studies relevant to the carcinogenicity assessment of chlorinated drinking-water two chemicals (sodium chlorite and hypochlorite salts) used in the chlorination of water eight of the by-products most frequently measured in drinking-water and three additional halogenated chemicals detected in drinking-water. Because of the formidable methodological obstacles faced by all investigations only one of these substances could be classified: bromodichloromethane was classified as possibly carcinogenic to humans. The final monograph considers data on metallic cobalt, cobalt alloys including cobalt-containing surgical implants and dental devices and cobalt compounds. In view of the strength of evidence linking cobalt metal powder and cobalt[II] oxide to cancer in experimental animals cobalt and cobalt compounds were classified as possibly carcinogenic to humans.

Book Description
Disinfection Byproducts in Drinking Water: Detection and Treatment presents cutting-edge research on how to understand the procedures, processes and considerations for detecting and treating disinfection by-products from drinking water, swimming pool water, and wastewater. The book begins with an overview of the different groups of Disinfection Byproducts (DBPs), such as: Trihalomethanes (THM), Halo acetic acids, and Haloacetonitrile (HAN). This coverage is quickly followed by a clear and rigorous exposition of the latest methods and technologies for the characterization, occurrence, formation, transformation and removal of DBPs in drinking water. Other chapters focus on ultraviolet-visible spectroscopy, electron spin resonance, and gas chromatography-mass spectrometry. Researchers will find a valuable resource to a breath of topics for DBP detection and treatment, including various recent techniques, such as microfiltration, nanofiltration membrane and nanotechnology. Explains the latest research in detection, treatment processes and remediation technologies Includes sampling, analytical and characterization methods and approaches Covers cutting-edge research, including membrane based technologies, nanotechnology treatment technologies and bioremediation treatment technologies Provides background information regarding contamination sources
