Download or read book Selenium Contamination in Water written by Pooja Devi and published by John Wiley & Sons. This book was released on 2021-05-12 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

Download or read book Agricultural Drainage Water Management in Arid and Semi arid Areas written by Kenneth K. Tanji and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2002 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains guidelines to sustain irrigated agriculture and protect water resources from the negative impacts of agricultural drainage water disposal. Using case studies from Central Asia, Egypt, India, Pakistan and the US, this study highlights four broad groups of drainage water management options and provides information to enable assessment of their impact and contribution towards development goals and to facilitate the preparation of drainage water management plans and designs. The options are: water conservation, drainage water re-use, drainage water disposal and drainage water treatment. The full texts of the case studies can be found on the attached CD-ROM.

Download or read book Biotechnology for the Treatment of Hazardous Waste written by Daphne L. Stoner and published by Routledge. This book was released on 2017-11-22 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of biologically based processes for the treatment of hazardous inorganic and organic wastes is a multi-disciplinary effort requiring the consideration of a number of biological, chemical, and physical parameters, as well as the effective teaming of biologists, chemists, engineers, and regulatory agencies. This new text/reference bridges the disciplines in a unique way, allowing an exchange of fundamental information to take place. The book begins with a description of the biological transformations of inorganic and organic compounds and a review of strategies that may be used for the treatment of hazardous wastes. It continues with a discussion of the physiological and engineering factors that must be considered for successful process development and concludes with a discussion of the regulations that have influenced biological waste treatment and environmental remediation.
Download or read book Novel Bioremediation Processes for Treatment of Seleniferous Soils and Sediment written by Shrutika Laxmikant Wadgaonkar and published by CRC Press. This book was released on 2018-10-26 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this Ph.D. was to develop a technology for the remediation of seleniferous soils/sediments and to explore microbial reduction of selenium oxyanions under different respiration conditions and bioreactor configurations. Seleniferous soil collected from the wheat-grown agricultural land in Punjab (India) was characterized and its soil washing was optimized by varying parameters, where addition of oxidizing agents showed a maximum selenium removal efficiency. Aquatic plants, Lemna minor and Egeria densa were used to study phytoremediation of the selenium-rich soil leachate containing oxidizing agents. Additionally, migration of the soluble selenium fraction from the upper to the lower layers and its subsequent reduction and accumulation in the lower layers of the soil column was observed during soil flushing. Furthermore, the soil leachate containing selenium oxyanions obtained from soil washing was treated in a UASB reactor by varying the organic feed. Ex situ bioremediation of selenium oxyanions was studied under variable conditions. An aerobic bacterium (Delftia lacustris) capable of transforming selenate and selenite to elemental selenium was isolated and characterized. Anaerobic bioreduction of selenate coupled to methane oxidation was investigated in serum bottles and a biotrickling filter using marine sediment as inoculum. Finally, the effect of contamination of other chalcogen oxyanions (tellurium) on selenium bioreduction was studied in a continuous system (UASB reactor).
