Book Description
The risk assessment approach described in this monograph applies only to essential trace elements (ETEs) involved in human health and not to non-essential elements. The purpose of this monograph is to provide the scientific principles that support the concept of an acceptable range of oral intake (AROI) which uses a homeostatic model for determining the range of dietary intakes for essential trace elements (ETEs) that meet the nutritional requirements of a healthy population and avoid excess intakes. To facilitate comparisons AROIs are discussed in relation to other risk assessment approaches. Although it includes examples this monograph is not a compendium of assessments on ETEs nor is it a textbook detailing the scientific basis of risk assessment of the derivation of dietary reference intakes. Described in the book is the process of risk assessment which begins with the selection of the database for a particular ETE. A weight-of-evidence approach is then used for hazard identification selecting relevant end-point of deficient and excess exposures. Next the probability of risk and the severity of various effects are quantified and critical effects are selected. The AROI is then established by balancing end-points of comparable health significance. At this time the exposure assessment is conducted. Finally a risk characterization enumerating the strengths and weaknesses of the databases is performed integrating the AROI and exposure assessment. ... The amount of work which is entailed in these volumes is very great and the low cost does not reflect the time of experts travelling nor even the hours expended UN staff in Geneva... This well informed book with its predecessors in the series is essential reading for biologists chemists and medical professionals concerned with essential trace elements. - The International Journal of Environmental Studies

Book Description
Experts explore the influence of trace metals on the pathogenesis of infectious diseases. Many parts of the world in which common infectious diseases are endemic also have the highest prevalence of trace metal deficiencies or rising rates of trace metal pollution. Infectious diseases can increase human susceptibility to adverse effects of metal exposure (at suboptimal or toxic levels), and metal excess or deficiency can increase the incidence or severity of infectious diseases. The co-clustering of major infectious diseases with trace metal deficiency or toxicity has created a complex web of interactions with serious but poorly understood health repercussions, yet has been largely overlooked in animal and human studies. This book focuses on the distribution, trafficking, fate, and effects of trace metals in biological systems. Its goal is to enhance our understanding of the relationships between homeostatic mechanisms of trace metals and the pathogenesis of infectious diseases. Drawing on expertise from a range of fields, the book offers a comprehensive review of current knowledge on vertebrate metal-withholding mechanisms and the strategies employed by different microbes to avoid starvation (or poisoning). Chapters summarize current, state-of-the-art techniques for investigating pathogen-metal interactions and highlight open question to guide future research. The book makes clear that improving knowledge in this area will be instrumental to the development of novel therapeutic measures against infectious diseases. Contributors M.

Book Description
In what ways can the process for developing Dietary Reference Intakes (DRIs) be enhanced? The workshop entitled "The Development of DRIs 1994-2004: Lessons Learned and New Challenges" offered a valuable window into the issues and challenges inherent in the development of nutrient reference values. The dialogue-carried out under the auspices of the Institute of Medicine (IOM), Food and Nutrition Board (hereafter referred to jointly as the IOM)-was enriched by the 10 years of experience in deriving the expanded set of values known as the DRIs, plus the decades of experience that grounded the earlier Recommended Dietary Allowances for the United States and the Recommended Nutrient Intakes for Canada. The lessons learned and the knowledge gained will guide decisions about the next phase of the DRIs. To paraphrase one participant, we are now asking better questions. In 2006, the IOM, with support from the United States and Canadian governments, undertook an effort to synthesize the research needs identified during the 10 years of DRI development. While the workshop summarized here was predicated on the fact that the development of DRIs is improved by better data, its focus was different. Its goals were to examine the framework and conceptual underpinnings for developing DRIs and to identify issues important for enhancing the process of DRI development. The workshop was designed to use the existing framework for DRI development as a basis for the discussions and to consider the components of the framework in sequence. Consideration of the pros and cons of the current conceptual underpinnings of the framework opened the workshop, followed by the general "road map" for decision making and the needed scientific criteria. Next, the challenges associated with providing guidance for users were explored. The Development of DRIs 1994-2004: Lessons Learned and New Challenges: Workshop Summary explains an array of issues germane to the future process for developing DRIs, including strategies for updating and revising existing DRIs and opportunities for stakeholder input.

Book Description
Risk Assessment for Human Metal Exposures: Mode of Action and Kinetic Approaches examines the current principles of risk assessment in human metal exposures, with a focus on Mode of Action(MOA), Toxicokinetic and Toxicodynamic (TKTD) considerations, and computer models. Derived from the highly respected Handbook on the Toxicology of Metals, Fourth Edition (2014), the book summarizes principles and methods and provides examples of how MOA –TKTD can be used. In addition, it presents tactics on how information generated by such methods can be confirmed by epidemiological data. Furthermore, it demonstrates how epidemiological data can be confirmed and evaluated by the examined models and considerations. This resource uniquely integrates several important topics, such as risk assessment, characterization, management and communication—the classic risk assessment paradigm—with mode of action, TKTD, and epidemiology, all topics related to human exposure. Written by pioneers in the field, this book is an essential reference for researchers, students and technicians in toxicology and risk assessment. Covers fundamental risk assessment concerns for the effects of metals on human health Provides an easy-to-use structure to quickly locate specific methods Uses case studies to illustrate the methods and theories described Written to be understood by students, researchers and industry workers who need to conduct risk assessment in metals and human health
