This book was released on 2007-05-02 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Space Station is a closed and complex environment, so some contamination of its internal atmosphere and water system is expected. To protect space crews from contaminants in potable and hygiene water, the National Aeronautics and Space Administration (NASA) requested that the National Research Council (NRC) provide guidance on how to develop water exposure guidelines and review NASA's development of the exposure guidelines for specific chemicals. NASA selects water contaminants for which spacecraft water exposure guidelines (SWEGs) will be established; this involves identifying toxicity effects relevant to astronauts and calculating exposure concentrations on the basis of those end points. SWEGs are established for exposures of 1, 10, 100, and 1,000 days. This report is the second volume in the series, Spacecraft Water Exposure Guidelines for Selected Chemicals. SWEG reports for acetone, alkylamines, ammonia, barium, cadmium, caprolactam, formate, formaldehyde, manganese, total organic carbon, and zinc are included in this report. The committee concludes that the SWEGs developed for these chemicals are scientifically valid based on the data reviewed by NASA and are consistent with the NRC (2000) report, Methods for Developing Spacecraft Water Exposure Guidelines. SWEG reports for additional chemicals will be presented in a subsequent volume.

Book excerpt: Evaluates the risks to human health and the environment posed by the mining, processing, and industrial use of barium. The opening sections review both natural and man-made sources of release into the environment, including nuclear fallout following the testing of weapons. A section on environmental behaviour notes the contribution of industrial emissions, especially from the combustion of coal and diesel oil, to the presence of barium in air. Particular concern centres on concentrations found in water, where barium may have a residence time of several hundred years. Water supplies and food are identified as the most important routes of exposure for the general population. Other sections review what is known about the kinetics and metabolism of barium, discuss its capacity to mimic the role of calcium in many physiological processes, and consider effects on organisms in the environment, including effects on the infectivity of several viruses.
