  • The impact of biotechnology on agricultural worker safety and health
    The impact of biotechnology on agricultural worker safety and health
    Jenkins SM ;
    Shutske JM
    2002/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    Biotechnology applications such as the use and production of genetically modified organisms (GMOs) have been widely promoted, adopted, and employed by agricultural producers throughout the world. Yet, little research exists that examines the implications of agricultural biotechnology on the health and safety of workers involved in agricultural prod ...
  • InDepth Survey Report Control of Perchloroethylene PCE in Vapor Degreasing Operations Site 2
    In-Depth Survey Report: Control of Perchloroethylene (PCE) in Vapor Degreasing Operations, Site #2
    Almaguer, Daniel ;
    Khan, Amir
    2002/08/01 | Engineering and Physical Hazards Survey Reports
    Worker exposures to perchloroethylene (PCE) occur in a large number of industries where PCE is used for organic solvent vapor cleaning (degreasing). Solvent degreasing does not constitute a distinct industrial category, but is an integral part of many major industries. This report examines worker exposures to PCE during the loading and unloading of ...

    Quantification of respirable, thoracic, and inhalable quartz exposures by FT-IR in personal impactor samples from construction sites
    Bello D ;
    Kalil AJ
    2002/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    The classification of quartz as a group 1 human carcinogen by the International Agency for Research on Cancer (IARC) highlights the need to develop a method to assess quartz exposures in the thoracic and inhalable particle size fractions to supplement the current method for the respirable size fraction. Heavy and highway construction operations can ...

    Jacob, Lilian C. B.
    2002/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    Despite the fact that the term occupational hearing loss is usually associated with noise-induced hearing loss, the scientific literature indicates that there are other work-related agents that can be damaging to the worker's auditory health. Lead is considered as one of these agents, and several researchers have investigated its effects on the aud ...

  • Comparative Pulmonary Toxicity of Blasting Sand and Five Substitute Abrasive Blasting Agents
    Comparative Pulmonary Toxicity of Blasting Sand and Five Substitute Abrasive Blasting Agents
    Barger M ;
    Battelli L
    2002/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    Blasting sand is used for abrasive blasting, but its inhalation is associated with pulmonary inflammation and fibrosis. Consequently, safer substitute materials for blasting sand are needed. In a previous study from this laboratory, the comparative pulmonary toxicity of five abrasive blasting substitutes and blasting sand was reported. In this stud ...

    Emerging Issues in Occupationally Relevant Zoonoses
    Hubbs, Ann F.
    2002/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    Diseases that are transmitted from animals to humans are known as zoonoses. Humans can contract such diseases directly from animals, as in the case of rabies. They also can contract zoonoses after environmental contamination; this is the case with leptospirosis (Weil's disease), which results from infected urine contaminated soil or water. Vectors ...

    2002/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    Like all types of farming, raising tobacco has many hazards that may lead to injury, disability, or death. Burley tobacco farming is a multistep process that is not highly mechanized. An 8-year emergency department surveillance system in Kentucky identified 674 injury cases related to the production of burley tobacco. Most of the injuries were a re ...
  • Investigation of Filter Bypass Leakage and a Test for Aerosol Sampling Cassettes
    Investigation of Filter Bypass Leakage and a Test for Aerosol Sampling Cassettes
    Baron, Paul A. ;
    Grinshpun SA
    2002/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    Plastic filter cassettes (37 and 25 mm), which are press fitted together to seal and hold a filter in place, are commonly used for sampling aerosols. Aerosol bypass leakage around the filter has been reported by several researchers and attempts have been made to test for leakage and to reduce the likelihood of leakage by improving cassette design. ...
