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 Application of Phytotechnologies for Cleanup of Industrial Agricultural and Wastewater Contamination written by Peter A. Kulakow and published by Springer Science & Business Media. This book was released on 2009-11-03 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: As government and community leaders, private companies, citizens, and applied scientists search for low-cost methods to cleanup environmental pollution, phytotechnologies can contribute to the solution by utilizing natural processes to reduce environmental risk. Phytotechnologies use vegetation to manage environmental contaminants in soil, surface water, and groundwater based on site-specific design considerations that can save 50 to 75 percent of the capital and operating costs compared to conventional remediation and containment technologies. Successful phytotechnology applications are based on scientific knowledge of plant physiology, chemical contaminants, climate, and soil conditions. This book presents current research findings that address soil and water contamination with obsolete pesticides, radionuclides and other inorganic and organic contaminants. This book documents international sharing of information by scientists and stakeholders seeking to use the best available information: to disseminate existing knowledge on phytotechnologies and exchange experience of field-scale applications for cleanup of industrial, agricultural, and wastewater contamination, to assess existing knowledge and identify research needs and directions for future work especially in regard to environmental management in Central and Eastern Europe and Central Asia, and to promote collaboration between different countries in preparing applications for environmental remediation and restoration.

Download or read book Aquatic Contamination written by Rouf Ahmad Bhat and published by John Wiley & Sons. This book was released on 2024-01-25 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: "More than two-thirds of the earth is covered with aquatic habitats that play a key role in stabilizing the global environment and providing a wide variety of services to increasing human needs. Nevertheless, anthropogenic activities are rapidly destroying the quality of both fresh and marine waters over the globe due to excessive use of chemicals and fertilizers, and pollution from suburban and industrial areas eventually make their way into the aquatic world. To preserve the integrity of aquatic environs is the greatest challenge in the current era because more than 80 per cent of urban wastewater, millions of tons of heavy metals chemical, toxic sludge and other waste are being directly discharged into inland waters. There are many reports that bacteria and plant species are using biodegradation and bioremediation strategies. The potential drivers of the commercial use of biological resources are yet to be explored as there are issues involved with technological facilitation and it's need for large investment funds, so there is a need to explore better training and development of more eco-friendly biological resources. After global investigation, the use of biological remediation technologies to deal with environmental problems should become standard practice, even though respondents are striving to apply bioremediation techniques. As microorganisms have evolved different survival strategies in heavier metal-polluted conditions such as biosorption, bioaccumulation or biomineralisation, which are either ex situ or in situ exploitation, these organisms are known to evolve and introduce specific detoxification mechanisms. The use of microbes as a time-saver for bioremediation was a result of the complexities involved in conventional soil regeneration methods. There are so many fungal species (like genera Penicillium, Aspergillus and Rhizopus) which has been identified as potential microbial agents for the removal of heavy metals from aqueous solutions but due to toxicity of chemical or heavy metals, it is difficult to maintain a healthy population of microorganisms hence high throughput genetic engineering tools and techniques need to be employed to attain resistant strains to degrade xenobiotic compounds. A novel technology for obtaining highly efficient biosorbents from endophytes, a hyperaccumulator, which is more convenient than the traditional method of obtaining biosorbents. Genomics, for instance in GMO plants, have been studied and used primarily in microbial genetics, but it is now a new instrument for bioremediation. Knowledge of genomics in the sense of understanding microbiological remediation provides a view of genes linked to microbial exposure to soil toxic metals. The use of genomics in bioremediation enables microorganisms to be analyzed on the basis both of biochemical and mechanism-related molecular levels."--

Download or read book Soil Remediation and Plants written by Khalid Hakeem and published by Academic Press. This book was released on 2014-08-29 with total page 771 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone's health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. - Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil - Examines the challenges and possibilities towards the various phytoremediation candidates - Includes the latest research and ongoing progress in phytoremediation
