    Sylvain, David C.
    2000/09/01 | Health Hazard Evaluation Reports (HHE)
    On January 27, 1999, the National Institute for Occupational Safety and Health (NIOSH) received a confidential request from staff at Haverhill High School in Haverhill, Massachusetts, for an evaluation of exposures to crystalline silica and other compounds in ceramics. The request indicated that employees were concerned about developing emphysema, ...

    Wallace, Marjorie E.
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    The manual transfer of powder dyes from bulk containers to smaller process containers generates significant amounts of dust. Worker exposure to dye dust through breathing or skin contact can result in adverse health effects such as occupational asthma, eczema, and severe allergic reactions. In addition, the National Institute for Occupational Safet ...

    Goodman, Gerrit V. R.
    2000/09/01 | Mining Publications
    The importance of controlling respirable dust and methane gas levels in underground coal mining cannot be underestimated. While respirable dust can significantly affect the occupational health of underground coal miners, methane gas accumulations pose significant safety concerns for these same workers. Water sprays and machine mounted dust scrubber ...

    Bailer AJ ;
    Dankovic, David A.
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Rodent studies are frequently used to assess risk in humans, yet it is not known whether the overloading of lung clearance, as observed in rodents, occurs in humans, or whether overloading is related to particle-related lung diseases in humans. The objective of this study is to develop a biologically based mathematical model to describe the retenti ...

    Changes in Bronchoalveolar Lavage Indices Associated with Radiographic Classification in Coal Miners
    Castranova, Vincent ;
    Goins M
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Previous studies on symptomatic coal miners have shown that alveolar macrophages, recovered by bronchoalveolar lavage (BAL), release excessive amounts of reactive oxygen species (ROS) and inflammatory cytokines. It has been proposed that these secretions may mediate cell injury and initiate the disease process. We hypothesized that acellular bronch ...

    Fuller DC ;
    Suruda, Anthony J.
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Alice Hamilton described fatal work injuries from acute hydrogen sulfide poisonings in 1925 in her book Industrial Poisons in the United States. There is no unique code for H2S poisoning in the International Classification of Diseases, 9th Revision; therefore, these deaths cannot be identified easily from vital records. We reviewed US Occupational ...

    The Occupational Physicians' Reporting Activity (OPRA) surveillance scheme for occupational physicians has now been in place for 4 years. During this period, an estimated 43,764 new cases of work-related disease have been reported. Musculoskeletal conditions make up nearly half (49%) of all cases; mental ill-health and skin disease account for 20% ...

    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Only recently have toxicologists come to understand the role of inflammation, and TNFalpha specifically, in classical toxicological processes. This relationship appears fairly complex, as inflammation and proliferation may well be only one facet of a time- and dose-dependent continuum of toxicological and repair processes. Not surprisingly, conside ...

    Nonenzymatic glycosylation contributes to the formation of crosslinks, which leads to the structural and functional deterioration of tissue protein. The accumulation of these crosslinks in tissue proteins has been implicated in the alteration of biomechanical properties of connective tissues. The objective of this study was to determine whether ten ...
