  • Physicochemical Determinants of Linear Alkylbenzene Sulfonate LAS Disposition in Skin Exposed to Aqueous Cutting Fluid Mixtures
    Physicochemical Determinants of Linear Alkylbenzene Sulfonate (LAS) Disposition in Skin Exposed to Aqueous Cutting Fluid Mixtures
    Barlow BM ;
    Baynes RE
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Linear alkylbenzene sulfonate (LAS) is added to cutting fluid formulations to enhance the performance of metal machining operations, but this surfactant can cause contact dermatitis in workers involved in these operations. The purpose of this study was to determine how cutting fluid additives influence dermal disposition of 14C-LAS in mineral oil- ...

    Barriers to Expanding the Use of Vacuum Attachments in Dry-Wall Sanding: A National Survey of Union Contractors and Finishers
    Ashyk D ;
    Blade, Leo M.
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Exposure to silica-containing dust has been measured at high levels for workers who sand drywall. For many years, vacuum attachments that effectively protect against dust exposure have been available, and yet anecdotal evidence suggests that they are not usually used. Surveys of contractors and drywall finishers were conducted in order to identify ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    During a recent NIOSH field survey, thermal desorption tubes were used to qualitatively determine any volatile organic compounds to which the workers were being exposed. Two major compounds in the samples were identified by gas chromatography-mass spectrometry as N,N-dimethylethanolamine (DMEA) and N,N-dimethylisopropanolamine (DMIPA). A short-term ...

    Lead exposure in radiator repair workers: a survey of Washington State radiator repair shops and review of Occupational Lead Exposure Registry data
    Whittaker SG
    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    In Washington State, radiator repair workers have the greatest number of very elevated (> 60 ug/dl) blood lead levels reported to the Occupational Lead Exposure Registry (Registry) of any other worker population. Consequently, we assessed lead exposure in Washington State's radiator repair workers by reviewing Registry data and conducting a statewi ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Although existing sampling and analytical methods for ammonia may be adequate for evaluating exposure relative to the OSHA-PEL (50 ppm TWA), many projects involving the short-term measurement of ppb concentrations require more sensitive methods. This project focuses on the modification of a fluorometric method previously developed for analysis of a ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Dry powdered dyes of many chemical types are used extensively to color textiles. These dyes are typically provided in bulk drums holding up to several hundred pounds and are removed as needed in measured amounts. This "weight-out" operation is the time of greatest potential exposure to employees. Worker exposure to dye dust through breathing or ski ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Silica gel is not known to produce significant disease or toxic effects when total dust exposures are kept under 10 mg/m3. In response to a worker inquiry as to whether silica gel desiccant used in a well-ventilated confined space could cause or exacerbate small air-ways disease, NIOSH obtained a bulk sample of the silica gel desiccant for analysis ...

    2002/06/01 | National Institute for Occupational Safety and Health (NIOSH)
    Gamma interferon (IFN) plays a key role in host defense against pulmonary mycobacterial infections. A variety of lymphocyte subsets may participate in producing pulmonary IFN responses, but their relative contributions after mycobacterial infection have not been clearly elucidated. To address this question, C57Bl/6 female mice were infected by intr ...

    Accounts of adult lead poisoning are among the oldest and best known in the toxicological literature. Dr. Alice Hamilton, a pioneer in the area of occupational illnesses, described lead as one of the oldest industrial poisons, dating back to ancient Roman times (1). Today, however, it is children and not adults who are usually the focus of lead tox ...
