    Biddle, Elyce A. ;
    Grosch J
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Prior research has shown that older workers experience high fatality rates due to traumatic occupational injuries. Between 1980 and 1997, there were 21,887 fatalities of civilian workers aged 55 years and older reported through the National Traumatic Occu­pational Fatalities (NTOF) surveillance system. Historically, the occupational fatality rate f ...

    Benzene Metabolism by the Isolated Perfused Lung
    Carlson GP ;
    Powley MW
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Benzene is an occupational hazard and environmental toxicant whose toxic effects are dependent on its metabolism by cytochrome P-450. Most physiologically based pharmacokinetic models assume that benzene is metabolized only in the liver. They may not be completely accurate in predicting metabolism, especially following inhalation exposure, if metab ...

    Ten-Year Update on Mortality Among Mild-Steel Welders
    Steenland, Kyle
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    This study is an update on the lung cancer risk of mild-steel welders with no asbestos exposure using a cohort of nonwelders for comparison. The subjects came from three United States (US) plants that manufactured heavy equipment. The follow-up was extended from 1988 to 1998. The welders were not exposed to asbestos (typical of shipyard welders) or ...

    Stachybotrys chartarum (atra) is a toxigenic fungus frequently found in water-damaged buildings. Although microbial volatile organic compounds (MVOCs) produced by Aspergillus, Penicillium, and other fungi have been investigated extensively, little information exists on what MVOCs can be produced by S. chartarum. In this study, three strains of S. c ...
