Download A Review on Advanced Treatment Methods for Arsenic Contaminated Soils and Water Book in PDF, ePub and Kindle
A number of treatment methods have been investigated in the laboratory or full scale to remove arsenic from drinking water and to remediate arsenic-contaminated sites. This paper gives a review on the advanced technologies for the treatment of arsenic-contaminated soils and water. Treatment methods such as oxidation, anion exchange, membrane separation, and adsorption/precipitation have been developed to remove arsenic from drinking water or groundwater. However, further research is needed to find new and more efficient substitute materials for the ion exchange resins, membranes, and adsorbents to improve the treatment and cost efficiencies. A stabilization/solidification method has been demonstrated successfully to contain arsenic in contaminated soils, sediments, and solid wastes. Vitrification is also applicable but may be more expensive due to the high energy requirements. Electrochemical methods based on electrokinetics are emerging. Especially, electrokinetics and electrodialysis are suited for fine-grained soils. Chemical extraction, either in-situ or ex-situ, can be efficient to remove bulk arsenic from contaminated soils and solid wastes. Selection of proper extractants is the key to the success of this method. Bioremediation, phytoremediation, and natural attenuation show great potential for future developments because of their environmental compatibility and cost effectiveness. Generally, it is critical to recognize that no single specific technology may be considered as generally applicable. Combination of existing technologies may provide an efficient and cost-effective treatment alternative. Use of biodegradable and environmentally benign products to enhance the remediation processes should be further investigated.

Download Managing Arsenic in the Environment Book in PDF, ePub and Kindle
Arsenic is one of the most toxic and carcinogenic elements in the environment. This book brings together the current knowledge on arsenic contamination worldwide, reviewing the field, highlighting common themes and pointing to key areas needing future research. Contributions discuss methods for accurate identification and quantification of individual arsenic species in a range of environmental and biological matrices and give an overview of the environmental chemistry of arsenic. Next, chapters deal with the dynamics of arsenic in groundwater and aspects of arsenic in soils and plants, including plant uptake studies, effects on crop quality and yield, and the corresponding food chain and human health issues associated with these exposure pathways. These concerns are coupled with the challenge to develop efficient, cost effective risk management and remediation strategies: recent technological advances are described and assessed, including the use of adsorbants, photo-oxidation, bioremediation and electrokinetic remediation. The book concludes with eleven detailed regional perspectives of the extent and severity of arsenic contamination from around the world. It will be invaluable for arsenic researchers as well as environmental scientists and environmental chemists, toxicologists, medical scientists, and statutory authorities seeking an in-depth view of the issues surrounding this toxin.

Download Best Practice Guide on the Control of Arsenic in Drinking Water Book in PDF, ePub and Kindle
Arsenic in drinking water derived from groundwater is arguably the biggest environmental chemical human health risk known at the present time, with well over 100,000,000 people around the world being exposed. Monitoring the hazard, assessing exposure and health risks and implementing effective remediation are therefore key tasks for organisations and individuals with responsibilities related to the supply of safe, clean drinking water. Best Practice Guide on the Control of Arsenic in Drinking Water, covering aspects of hazard distribution, exposure, health impacts, biomonitoring and remediation, including social and economic issues, is therefore a very timely contribution to disseminating useful knowledge in this area. The volume contains 10 short reviews of key aspects of this issue, supplemented by a further 14 case studies, each of which focusses on a particular area or technological or other practice, and written by leading experts in the field. Detailed selective reference lists provide pointers to more detailed guidance on relevant practice. The volume includes coverage of (i) arsenic hazard in groundwater and exposure routes to humans, including case studies in USA, SE Asia and UK; (ii) health impacts arising from exposure to arsenic in drinking water and biomonitoring approaches; (iii) developments in the nature of regulation of arsenic in drinking water; (iv) sampling and monitoring of arsenic, including novel methodologies; (v) approaches to remediation, particularly in the context of water safety planning, and including case studies from the USA, Italy, Poland and Bangladesh; and (vi) socio-economic aspects of remediation, including non-market valuation methods and local community engagement.
