    2002/07/01 | Fatality Assessment and Control Evaluation Reports (FACE)
    Background: By the time teenagers leave high school, approximately 80 percent will have held a job. While work has many benefits, it also can pose risks. Approximately 70 teenagers under the age of 18 in the US die each year from injuries incurred on the job. In this incident the victim was performing a task prohibited for teens under the child lab ...

    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    This paper identifies and ranks food items by estimating their contribution to the dietary exposure of the US population and 19 subpopulation groups. Contributions to dietary exposures to arsenic, cadmium, chromium, lead, nickel, benzene, chlorpyrifos, and diazinon are estimated using either the Dietary Exposure Potential Model (DEPM) approach, the ...
  • Comparison of Endotoxin Assays Using Agricultural Dusts
    Comparison of Endotoxin Assays Using Agricultural Dusts
    Connaughton I ;
    Croteau EA
    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Endotoxins from gram-negative bacteria pose a significant respiratory hazard. Establishing dose-response relationships is problematic because there are no standard procedures for sampling and analysis. The goal of this study was to compare endotoxin analyses in six laboratories using Limulus-based assays for analysis of organic dusts from three agr ...
  • NIOSH Evaluates Worker Exposures at a Popcorn Plant in Missouri

  • Methods for assessing risks of dermal exposures in the workplace
    Methods for assessing risks of dermal exposures in the workplace
    Boeniger, Mark F. ;
    McDougal JN
    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    The skin as a route of entry for toxic chemicals has caused increasing concern over the last decade. The assessment of systemic hazards from dermal exposures has evolved over time, often limited by the amount of experimental data available. The result is that there are many methods being used to assess safety of chemicals in the workplace. The proc ...

    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    A number of prospective studies have examined lead levels in umbilical cord blood at birth as predictors of infant mental development. Although several have found significant inverse associations, others have not. Measurement of lead levels in maternal bone, now recognized as the source of much fetal exposure, has the potential to serve as a better ...

    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Home care is one of the most rapidly expanding segments of the health care industry, with both demographic and fiscal pressures ensuring that this type of care will continue into the future. Much of the care is provided by low wage workers, mostly women, without the typical protections and benefits that workers in traditional health care settings r ...

    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    The actin filament-associated protein and Src-binding partner, AFAP-110, is an adaptor protein that links signaling molecules to actin filaments. AFAP-110 binds actin filaments directly and multimerizes through a leucine zipper motif. Cellular signals downstream of Src(527F) can regulate multimerization. Here, we determined recombinant AFAP-110 (rA ...

    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Metal working fluids (MWFs) are widely used in industry for metal cutting, drilling, shaping, lubricating, and milling. Many occupational health concerns have arisen for workers exposed to MWFs. It has been reported earlier that occupational exposure to MWFs causes allergic and irritant contact dermatitis. Previously, we have shown that dermal expo ...

    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    A major health hazard to coal miners is development of emphysema following long-term exposure to coal dust. One mechanism underlying development of emphysema is the oxidation of critical methionine (Met) residues in antiproteolytic factor, alpha1-antitrypsin (A1AT) resulting in a protease-antiprotease imbalance in the lung. Several studies have doc ...

    Work-related asthma (WRA) is the most common work-associated respiratory disease in developed countries. We report shark cartilage dust as a new potential cause of occupational asthma (OA) in the context of other fatal OA case reports. A 38-year-old white male worked for 8 years in a facility which primarily granulated and powdered various plastics ...

    Anti-vibration gloves have been used as personal protective equipment to reduce the exposure intensity of hand-transmitted vibration. Although a method based upon the measured transfer function has been recently proposed to predict the tool-specific anti-vibration performance of these gloves, its validity for real tool applications has not been suf ...
