  • Influence of face shields on exposures to respirable aerosol
    Influence of face shields on exposures to respirable aerosol.
    Jones RM ;
    Sleeth DK
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    The objective of this study was to determine the influence of face shields on the concentration of respirable aerosols in the breathing zone of the wearer. The experimental approach involved the generation of poly-dispersed respirable test dust aerosol in a low-speed wind tunnel over 15 min, with a downstream breathing mannequin. Aerosol concentrat ...
  • Crosswalks to Convert US Census Bureau Industry and Occupation Codes 19802018
    Crosswalks to Convert US Census Bureau Industry and Occupation Codes, 1980–2018
    Beard JD ;
    Bonsrah DA
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Occupation is reflective of workers' socioeconomic status (SES) and occupational exposures and experiences. Therefore, occupation has been used as a measure of SES, much like education and income, or to derive occupation-based indices of SES in many epidemiologic studies. Moreover, industry and occupation can be used to generate hypotheses regardin ...

  • Early care and education workers experience and stress during the COVID19 pandemic
    Early care and education workers' experience and stress during the COVID-19 pandemic.
    Otten JJ ;
    Quinn EL
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Early care and education (ECE) workers experience many job-related stressors. During the COVID-19 pandemic, ECE programs either closed or remained open while workers faced additional demands. We deployed a survey of the center-based ECE workforce in Washington State (United States) one year into the COVID-19 pandemic to assess impacts and workers' ...

    Physiological Impacts of Surgical Mask Coverage of Elastomeric Half-Mask Respirator Exhalation Valves in Healthcare Workers
    Chen HH ;
    Hines SE
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Objectives: Elastomeric half-mask respirator (EHMR) use in healthcare increased significantly during the COVID-19 pandemic. Concern for potential release of infectious aerosols from EHMR exhalation valves prompted recommendations to cover them with surgical masks (SMs), thereby improving source control. The physiological and subjective effects of w ...

  • Respiratory Health of American Indian and Alaska Native Coal Miners Participating in the Coal Workers Health Surveillance Program 20142019
    Respiratory Health of American Indian and Alaska Native Coal Miners Participating in the Coal Workers’ Health Surveillance Program, 2014–2019
    Blackley DJ ;
    Hall NB
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Background: In 2014, a federal rule reduced occupational exposure limits to coal mine dust and expanded medical surveillance eligibility beyond underground miners to surface and contract coal miners. This expansion may have provided an opportunity for more American Indian and Alaska Native (AI/AN) coal miners to participate in screening, since many ...

    Jones RM ;
    Kaur K
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Aerosolization of SARS-CoV-2 by COVID-19 patients can put healthcare workers and susceptible individuals at risk of infection. Air sampling for SARS-CoV-2 has been conducted in healthcare settings, but methods vary widely and there is need for improvement. The objective of this study was to evaluate the feasibility of using a high-volume filter sam ...

  • Comparative pulmonary toxicities of lunar dusts and terrestrial dusts TiO2 SiO2 in rats and an assessment of the impact of particlegenerated oxidants on the dusts toxicities
    Comparative pulmonary toxicities of lunar dusts and terrestrial dusts (TiO2 & SiO2) in rats and an assessment of the impact of particle-generated oxidants on the dusts' toxicities.
    Barger M ;
    Castranova, Vincent
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Humans will set foot on the Moon again soon. The lunar dust (LD) is potentially reactive and could pose an inhalation hazard to lunar explorers. We elucidated LD toxicity and investigated the toxicological impact of particle surface reactivity (SR) using three LDs, quartz, and TiO2. We first isolated the respirable-size-fraction of an Apollo-14 reg ...

  • Security Cameras in Taxicabs with Three Rows of Seating
    Security Cameras in Taxicabs with Three Rows of Seating
    Zeng S
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Taxicab security cameras are widely used to deter crimes against taxicab-drivers in two-row-seating taxicabs. Some of these cameras have difficulty for use in three-row-seating taxicabs due to increased distance between the camera and the third-row seats. This project tested five sample taxicab security cameras with different image-sensor pixel cou ...

    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    The toxicity of many "inert" ingredients of pesticide formulations, such as safeners, is poorly characterized, despite evidence that humans may be exposed to these chemicals. Analysis of ToxCast data for dichloroacetamide safeners with the ToxPi tool identified benoxacor as the safener with the highest potential for toxicity, especially liver toxic ...

    Long lasting permethrin-impregnated (LLPI) clothing can retain permethrin and repel ticks for up to three months and without exceeding EPA-approved safe levels; however, little is known about longer term effects of wearing LLPI clothing. Here, permethrin content was measured in new forester pants soon after initial impregnation (Insect Shield) and ...
