Book Description
Provides a comprehensive chemical and biochemical treatment on the effects of chromium in the environment and in man. Such an integrated treatment of the chemical and biochemical aspects of chromium is novel and has not appeared in the published literature. Reviews the information on global cycling and environmental occurrence of chromium compounds, which defines the extent of the environmental and toxicological concern. The treatment of chromium chemistry provides the basis for toxicological models of chromium hypersensitivity, mutagenicity, carcinogenicity, and toxicokinetics. Chapters contain graphical representations of the voluminous mutagenicity and animal carcinogenicity data according to chromium compound type, and a tabular summary of all published epidemiological data, broken down according to industry. Also covers clinical patterns, prognosis, pathogenesis, prophylaxis, and environmental and biological monitoring.

Book Description
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 Description
The importance of understanding complex toxicological and chemical properties of hexavalent and trivalent chromium has increased rapidly over the last few years as state and federal regulators reevaluate environmental standards. The risk management of chromium-contaminated soils continues to be a very dynamic process that presents interesting challenges. Chromium in Soil discusses the challenges faced by those investigating and remediating chromium-impacted soils and groundwater. The chapters address numerous ground-breaking developments in various fields of environmental chromium research, including toxicity, chemistry, environmental fate and transport, remediation technology, and health-based cleanup standards.

Book Description
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 Description
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.
