    Colicino E ;
    Dasaro CR
    2024/12/09 | National Institute for Occupational Safety and Health (NIOSH)
    Background: In the aftermath of the World Trade Center (WTC) attack on 11 September 2001, rescue and recovery workers faced hazardous conditions and toxic agents. Prior research linked these exposures to adverse health effects, but mainly examined individual factors, overlooking complex mixture effects. Methods: This study applies an exposomic appr ...
  • Assessment of Dermal Sensitization by Nickel Salts in a Novel Humanized TLR-4 Mouse Model (Dataset)
    Aldinger, Jeffrey A. ;
    Anderson S
    2024/12/09 | National Institute for Occupational Safety and Health (NIOSH)
    Nickel is one of the most common contact allergens worldwide. Despite this prevalence, many of the underlying immunological mechanisms responsible for nickel allergy remain unclear. This knowledge gap is partially attributable to the inherent resistance of laboratory rodents (mice and rats) to dermal sensitization with nickel salts. The fundamental ...

    Chiggers are larval mites that pose a significant health risk globally via the spread of scrub typhus. However, fundamental studies into the bacterial microbiome in North America have never been considered. In this investigation, chiggers were collected in the wild from two locally common rodent host species (i.e., Sigmodon hispidus and Peromyscus ...
  • Effect of Physicochemical Properties on Critical Sinking and Attachment of Respirable Coal Mine Dust Impacting on a Water Surface
    Effect of Physicochemical Properties on Critical Sinking and Attachment of Respirable Coal Mine Dust Impacting on a Water Surface
    Han S ;
    Rezaee M
    2024/12/05 | National Institute for Occupational Safety and Health (NIOSH)
    Respirable coal mine dust (RCMD) inhalation is identified as the main cause of the resurgence of coal worker's pneumoconiosis (CWP) since the mid-1990s. At present, the predominant dust control technology is the water spray system. However, in practice, the capture efficiency of RCMD by this technology is relatively low. To understand the capturing ...

    2024/12/05 | National Institute for Occupational Safety and Health (NIOSH)
    Rockfalls pose a significant risk to personnel and equipment in open pit mines, yet there is currently no widely adopted tool for the detection and real-time monitoring of these hazards. This paper explores the use of thermal infrared cameras to observe, detect, and record rockfall events in surface mining operations, with the aim of protecting min ...
