Book Synopsis Arsenic is Everywhere: Cause for Concern? by : William R Cullen
Download or read book Arsenic is Everywhere: Cause for Concern? written by William R Cullen and published by Royal Society of Chemistry. This book was released on 2016-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic is a naturally occurring element and, as such, it is present in the environment and in our food and drink. It can even be involved in supporting life processes. However, due to its toxicity, there is concern about its presence in our diet. This book examines the real risks and impacts of arsenic in our lives. Looking at arsenic and its compounds, this book explores the presence of arsenic in food and water, the need to clarify its toxicity, and current scientific and public misconceptions about arsenic. It also looks at the use of arsenic in medicine, from cancer treatments to alternative therapies such as homeopathy. Following on from "Is Arsenic an Aphrodisiac?: The Sociochemistry of an Element", this book continues the authors work in addressing the issues surrounding arsenic. It is a fascinating read for general readers as it unveils the reality of our exposure to arsenic in our daily lives.
Book Synopsis The Metabolism of Arsenite by : Joanne M. Santini
Download or read book The Metabolism of Arsenite written by Joanne M. Santini and published by CRC Press. This book was released on 2018-10-03 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up to 200 million people in 70 countries are at risk from drinking water contaminated with arsenic, which is a major cause of chronic debilitating illnesses and fatal cancers. Until recently little was known about the mobility of arsenic, and how redox transformations determined its movement into or out of water supplies. Although human activities contribute to the release of arsenic from minerals, it is now clear that bacteria are responsible for most of the redox transformation of arsenic in the environment. Bacterial oxidation of arsenite (to the less mobile arsenate) has been known since 1918, but it was not until 2000 that a bacterium was shown to gain energy from this process. Since then a wide range of arsenite-oxidizing bacteria have been isolated, including aerobes and anaerobes; heterotrophs and autotrophs; thermophiles, mesophiles and psychrophiles. This book reviews recent advances in the study of such bacteria. After a section on background—geology and health issues—the main body of the book concerns the cellular machinery of arsenite oxidation. It concludes by examining possible applications. Topics treated are: The geology and cycling of arsenic Arsenic and disease Arsenite oxidation: physiology, enzymes, genes, and gene regulation. Community genomics and functioning, and the evolution of arsenite oxidation Microbial arsenite oxidation in bioremediation Biosensors for arsenic in drinking water and industrial effluents

Book Synopsis Final Project Report on Arsenic Biogeochemistry in the Clinch River and Watts Bar Reservoir, Volume 2 by :
Download or read book Final Project Report on Arsenic Biogeochemistry in the Clinch River and Watts Bar Reservoir, Volume 2 written by and published by . This book was released on 1995 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic contamination was studied in the Clinch River/Watts Bar Reservoir (CR/WBR) system downstream from the U.S. Department of Energy's Oak Ridge Reservation (ORR). Arsenic is of particular interest and concern because (1) it occurs commonly in coal-bearing rock and waste products such as fly ash associated with the burning of coal, (2) it is classified as a Class A carcinogen by the U.S. Environmental Protection Agency, and (3) disposal of fly ash, both on and off the ORR, may have contaminated surface water and sediments in the Clinch River and Watts Bar Reservoir. The present study differs from previous reports on arsenic concentrations in the CR/WBR system in the use of much more sensitive and precise processing and analytical techniques to measure arsenic species (arsenate, arsenite, and organic arsenic) at levels well below the ecological and human health risk screening criteria. The absolute detection limits using these techniques are approximately 20 to 40 pmol/L, or 0.0015 to 0.003 {micro}g/L. Four main sites were sampled quarterly over a 3-year period (1990 through 1992). Sites investigated included Lower Watts Bar Reservoir near the Watts Bar Dam (Tennessee River kilometer 849.6), the Kingston area (Clinch River kilometer 1.6), Poplar Creek (Poplar Creek kilometer 1.6), and the McCoy Branch Embayment (McCoy Branch kilometer 0.3). Additional sites were investigated in the vicinity of these main stations to determine the distribution of contamination and to identify possible alternative or additional sources of arsenic. Detection limits that were a factor of 20 below the minimum risk screening criteria were achieved for 100% of arsenic speciation data. However, 118 samples for inductively coupled plasma metals analysis were not preserved to analytical specifications, and the analytical holding times for 180 ion chromatography samples were not met. More rigorous preservative testing protocols and more tightly defined analytical statements of work will prevent these problems in the future. Introduction, background, materials and methods, results, discussion, and conclusions are presented in Volume 1. The Quality Assurance/Quality Control Summary Report; the listing of water quality and surface water arsenic speciation data by source and site; and the listing of pore water arsenic speciation and particle-to-water distribution coefficients for As, Fe, and Mn by source, site, and season are presented in Volume 2. The Clinch River Environmental Restoration Program is currently completing the second phase of the Clinch River Remedial Investigation, with the intent of performing a baseline risk assessment on collected data. The data collected for this report will contribute to the baseline risk assessment for the Clinch River. Many of the goals of the Clinch River Remedial Investigation were refined using the results of this study.
