Download or read book The Nutritional Biochemistry of Chromium(III) written by John Vincent and published by Elsevier. This book was released on 2011-10-13 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromium nutritional supplements are the second best selling mineral supplements after calcium as chromium is found in pills, sports drinks, chewing gums, smoothies, and numerous other products. Chromium has been promoted to promote weight loss and muscle development and most recently to be available to treat the symptoms of type 2 diabetes and related conditions. The aim of The Nutritional Biochemistry of Chromium(III) is to examine the four most controversial areas of chromium nutrition and biochemistry: - is chromium an essential element for humans and are chromium nutritional supplements of value? - what biochemical role, if any, does chromium play in the body - can large doses of chromium(III) be used to treat symptoms of type 2 diabetes, cardiovascular disease, and related medical conditions - is the use of chromium(III) supplements a health concern. Scientific experts, who are recognized leaders in the field, weigh in with their opinions on both sides of these issues in this book. A background review of the field from 1955-1995 by Vincent opens the book and concludes with a summary by Dr. Forrest Nielsen, Center Director of the USDA's Grand Forks Human Nutrition Research Center concludes the book. * Point-counterpoint format, providing both sides of major issues * Complete coverage of current issues, including nutrition, health, biochemical role and toxicology * Authors are recognised experts and leaders in this field
Book Synopsis Low-Level Hexavalent Chromium Treatment Options by : Philip Brandhuber
Download or read book Low-Level Hexavalent Chromium Treatment Options written by Philip Brandhuber and published by American Water Works Association. This book was released on 2005-07-31 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: In February 1999, the California Office of Environmental Health Hazard Assessment issued a Public Health Goal (PHG) for total chromium of 2.5 μg/L. The PHG, based on a 10^6 risk level for 0.2 μg/L hexavalent chromium [Cr(VI)], was 40 times less than the USEPA's contaminant MCL of 100 μg/L for total chromium [Cr(III) ] Cr(VI)]. The success of the movie Erin Brockovich, which popularized a groundwater chromium pollution lawsuit in Hinkley, California, sensitized the public to the health hazards of chromium in drinking water. In 2001, the California state legislature passed a bill requiring the California Department of Health Services to adopt an MCL for Cr(VI). All of these actions must be viewed from the perspective that, at the time, no technology had been demonstrated to be effective at treating chromium to concentrations consistent with the total chromium PHG or the Cr(VI) 10^6 risk level of 0.2 μg/L. The purpose of this report was to present the results of this partnership study, which included an analysis of chromium occurrence and co-occurrence, an evaluation of Cr(VI) removal technologies, and an examination of chromium oxidation and reduction chemistry. This study investigated nearly all of the potential methods of controlling Cr(VI) either through the use of technologies that remove Cr(VI) directly (adsorption, anion exchange, membrane filtration) or those that remove the reduced form of chromium, Cr(III) (precipitation with membranes or coagulation and precipitation with conventional or membrane filters). These technologies were investigated using laboratory-scale testing methods, including batch isotherm tests, bench membrane systems, flow-through mini-columns, and jar testing techniques. For most technologies, controlled water matrices were used to screen performance. Selected technologies were further assessed using natural groundwater matrices from the Los Angeles Department of Water and Power and the Glendale Water and Power groundwater facilities.

Download or read book Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc written by Institute of Medicine and published by National Academies Press. This book was released on 2002-07-19 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.
Book Synopsis Occurrence Survey of Boron and Hexavalent Chromium by : Michelle Frey
Download or read book Occurrence Survey of Boron and Hexavalent Chromium written by Michelle Frey and published by American Water Works Association. This book was released on 2005-07-31 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Only limited information existed about the occurrence of boron and chromium in drinking water sources prior to this project. In addition, chromium speciation in drinking water sources was not well understood. In fact, due to analytical method deficiencies, previous field sampling experiences had resulted in total chromium concentrations less than corresponding hexavalent chromium concentrations. This project specifically addressed the following questions: . What are the analytical method challenges and sensitivities for reliable low-level detection of chromium species and boron in drinking water supplies? . What are the national occurrence patterns for chromium species and boron in drinking water sources? . What is the fate of these compounds through drinking water facilities and distribution systems? The project approach included . an investigation of analytical challenges for both chromium and boron analysis, . a review of existing occurrence data sources, . a design and an implementation of the national occurrence survey, . an analysis of the national occurrence results, and . an investigation of the fate of chromium and boron through drinking water facilities and distribution systems.

Download or read book Biological and Environmental Aspects of Chromium written by S. Langård and published by Elsevier. This book was released on 2013-10-22 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological and Environmental Aspects of Chromium focuses on the biological and environmental aspects of chromium and its compounds, with emphasis on the most important aspects of their toxicology and physiology. Topics covered range from the production and occupational exposure of chromium compounds to the presence of chromium in air, soil, and natural waters. The applications of chromium in cell biology and medicine are also discussed. Comprised of 11 chapters, this volume begins with an overview of the toxic and carcinogenic effects of chromium and chromium compounds, followed by a discussion on the production and occupational exposure of chromium compounds. The reader is then introduced to the more common analytical methods used in the determination of chromium in environmental and biological samples. Subsequent chapters explore the nutritional role of chromium; absorption, transport, and excretion of chromium in humans and animals; mutagenic and cytogenetic effects of chromium compounds; and organ toxicity of chromium in animals. The carcinogenic effects of chromium, including its effects on the skin, are also considered. This monograph will be of interest to students, practitioners, and researchers in the fields of biology, physiology, and chemistry, as well as those with an objective interest in the ways in which chromium and its compounds act in biological materials and in the human environment.
