  • Significance of radiation exposure from workrelated chest xrays for epidemiologic studies of radiation workers
    Significance of radiation exposure from work-related chest x-rays for epidemiologic studies of radiation workers
    Buncher CR ;
    Cardarelli, John J. II
    2001/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Introduction: Occupational epidemiologic studies provide an opportunity to evaluate the health risks from exposure to low-levels of ionizing radiation. These studies rarely include exposures from medical sources. In two studies of atomic bomb survivors, the authors concluded that medical x-ray exposures should be evaluated to better understand the ...

    Shi X
    2001/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Chromium (VI) compounds are widely recognized as human carcinogens. Extensive studies in vitro and in model systems indicate that the reactive intermediate, Cr (V), generated by cellular reduction of Cr (VI), is likely the candidate for the ultimate carcinogenic form of chromium compounds. Here we review our current understanding of the in vivo red ...

    Page, Steven J.
    2001/06/01 | Mining Publications
    Airborne dust generation is one of the byproducts of coal mining, processing, and handling. The amount of airborne total dust (ATD, respirable size and larger) and airborne respirable dust (ARD) generated is of primary interest for designing the level of engineering controls needed for adequate dust abatement. Laboratory crushing experiments were c ...

    Perry WG
    2001/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Epidemiologic and animal studies have identified several metals and metal-containing compounds as potent mutagens and carcinogens. The metals associated with these biological effects include As, Cd, Cr, and Ni. During the last two decades, chemical and cellular studies have contributed enormously to our understanding of metal-induced carcinogenesis ...

    The purpose of this study was to examine a broad range of toxicologic responses in rats exposed to a multi-component pollutant atmosphere. Cumulative and adaptive respiratory tract responses to 3 concentrations of an inhaled particle-oxidant mixture were examined in Fisher 344 N rats exposed 4 h/day, 3 days/week for 4 weeks. The mixtures contained ...

    Problem: Compared to other industries, construction has the third-highest death rate. Many agree, and research has shown, that one way to change these statistics is through effective worker safety and health training. Little is known about the quality and nature of safety and health training available to open-shop (nonunion) construction workers. M ...

    Technological intervention to eliminate back injury risks for nailing
    Bernold LE ;

    2001/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    "Ergonomics" is derived from the Greek words "ergon,"' meaning work. and "nomos,'' meaning natural laws. Thus, one can interpret ergonomics as the "natural laws of work." As documented in the literature, ergonomics has long been ignored by management and workers in construction alike. Unfortunately, a sore back in the evening is not always the effe ...

    Introduction: Chlorpyrifos is an organophosphorus insecticide widely used in the United States to control structural termites. It is metabolized in the liver to chlorpyrifos oxon, which is further detoxified to 3,5,6-trichloro-2-pyridinol (TCP) and excreted into the urine. The mean urine elimination half-life of TCP in humans after administration o ...

    Cr (VI) compounds are widely used industrial chemicals and are recognized human carcinogens. The mechanisms of carcinogenesis associated with these compounds remain to be investigated. The present study focused on dose-dependence of Cr (VI)-induced uptake and cellular responses. The results show that Cr (VI) is able to enter the cells (human lung e ...

    Tumor promoting effects of arsenic are believed to be associated with its transactivation activity on transcription factors, such as AP-1 and NFkappaB. However, the results from different groups studying the effects of arsenic on NFkappaB activation are contradictory in different cell models. Since arsenic is a strong skin carcinogen, we have inves ...
