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 798 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.

Download or read book Boron written by C. Smallwood and published by . This book was released on 1998 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book evaluates the risks to human health and the environment posed by boron, a naturally occurring element widely distributed in the form of various inorganic borates in the oceans, sedimentary, rocks, coal, shale and some soils. Boron is also used in laundry bleach and in the manufacture of glass, glass products, fertilizers and herbicides, antiseptics, and pharmaceuticals. Since boron is widely detected in drinking-water and occurs naturally in fruits, nuts, and vegetables, the report gives particular attention to health risks associated with exposure of the general population through diet and drinking-water.A section on sources of human and environmental exposure cites evidence that boron enters the environment mainly through volatilization from seawater, volcanoes, geothermal steam, and natural weathering of clay-rich sedimentary rock. Although industrial uses account for much smaller releases, the report notes that all of the boron from the sodium perborate contained in detergents ultimately enters the wastewater system, and is not removed by standard water treatment procedures.

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 Boron in Soils and Plants written by R.W. Bell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The economic significance of boron (B) in agriculture, horticulture, and forestry has been beyond dispute for several decades. Even in the last two decades, the areas where B deficiency limits plant production has grown with increased reports from China, south Asia and southeast Asia. The present volume is reflective of the growing awareness of the significance of low soil B with reports from Australia, Bangladesh, Brazil, north, central and southern China, India, Nepal, and the North West Frontier Province of Pakistan contained herein. Boron deficiency also continues to be a problem for crop yield and quality in areas where B deficiency has been known for some time, for example in Germany and the USA. The problem of low soil B is not limited to effects on field crop yield, with papers reporting on depressed wood yield and quality in timber trees (Lambert et al. ), and depressed fruit quality (Dong et al. ; Smith et al. : Zude et al. ) also appearing in the present volume. Globally, Shorrocks (1997)1 estimates that ?? tonnes of B fertiliser is applied annually in agriculture. The economic benefits from the use of B fertiliser have not been quantified but are clearly enormous. Paradoxically, the clear economic imperatives for using B fertiliser on low B soils are not matched by a similar clarity of understanding of the role and functions of B in plants.

Download or read book Boron Separation Processes written by Nalan Kabay and published by Elsevier. This book was released on 2015-01-19 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impending crisis posed by water stress and poor sanitation represents one of greatest human challenges for the 21st century, and membrane technology has emerged as a serious contender to confront the crisis. Yet, whilst there are countless texts on wastewater treatment and on membrane technologies, none address the boron problem and separation processes for boron elimination. Boron Separation Processes fills this gap and provides a unique and single source that highlights the growing and competitive importance of these processes. For the first time, the reader is able to see in one reference work the state-of-the-art research in this rapidly growing field. The book focuses on four main areas: - Effect of boron on humans and plants - Separation of boron by ion exchange and adsorption processes - Separation of boron by membrane processes - Simulation and optimization studies for boron separation - Provides in one source a state-of-the-art overview of this compelling area - Reviews the environmental impact of boron before introducing emerging boron separation processes - Includes simulation and optimization studies for boron separation processes - Describes boron separation processes applicable to specific sources, such as seawater, geothermal water and wastewater
