Book Description
Biokinetic modeling provides a mathematical technique for estimating absorption, distribution, metabolism, and excretion of chemicals, including particles and metals, in humans. Such models can be used to relate the amount of lead external exposure to the amount of lead found in the blood and other tissues at different points in time. At the request of the Department of Defense (DoD), Review of the Department of Defense Biokinetic Modeling Approach in Support of Establishing an Airborne Lead Exposure Limit evaluates whether the model used by DoD to derive airborne lead concentrations from blood lead levels is appropriate. This report also considers whether DoD's modifications to the model are appropriately justified, and whether the assumptions in and inputs to the model are reasonable.

Book Description
Between 1942 and 1975, the U.S. Army conducted tests with human subjects to study the effects of a variety of agents, including chemical warfare and biological agents. The potential long-term health effects on the test subjects from their exposures have been evaluated periodically, most recently in a report titled Assessment of Potential Long-Term Health Effects on Army Human Test Subjects of Relevant Biological and Chemical Agents, Drugs, Medications and Substances: Literature Review and Analysis (the Report), which was prepared by a contractor to assist the Army with making determinations about providing medical care to former test subjects. In response to a request by the Army, the National Academies of Sciences, Engineering, and Medicine formed a committee that was tasked with examining whether the Report appropriately identified potential long-term health effects from exposure to the test agents and whether an adequate weight-of-evidence approach was used to characterize the strength of the associations between the agents and their potential health effects. The committee was made aware at its first meeting on November 30, 2017, that the Army had already begun to receive applications for medical care and that some determinations may need to be made before the committee's evaluation of the Report was completed. Because of this urgency, the Army developed a process by which applications for medical care will be reviewed, and as a result, the committee was given the additional task of reviewing the Army's Memorandum that describes the approach that will be used by the Army to evaluate agent- and outcome-specific associations. This interim report was prepared to facilitate the Army's deliberations. A review of the Report is presented first, followed by a review of the Memorandum.

Book Description
For more than 100 years, the Coeur d' Alene River Basin has been known as "The Silver Valley" for being one of the most productive silver, lead, and zinc mining areas in the United States. Over time, high levels of metals (including lead, arsenic, cadmium, and zinc) were discovered in the local environment and elevated blood lead levels were found in children in communities near the metal-refining and smelter complex. In 1983, the U.S. Environmental Protection Agency (EPA) listed a 21-square mile mining area in northern Idaho as a Superfund site. EPA extended those boundaries in 1998 to include areas throughout the 1500-square mile area Coeur d'Alene River Basin project area. Under Superfund, EPA has developed a plan to clean up the contaminated area that will cost an estimated $359 million over 3 decades-and this effort is only the first step in the cleanup process. Superfund and Mining Megasites: Lessons from Coeur d'Alene River Basin evaluates the issues and concerns that have been raised regarding EPA's decisions about cleaning up the area. The scientific and technical practices used by EPA to make decisions about human health risks at the Coeur d'Alene River Basin Superfund site are generally sound; however, there are substantial concerns regarding environmental protection decisions, particularly dealing with the effectiveness of long-term plans.
