  • Estimating LongTerm PM1025 Concentrations in Six US Cities Using SatelliteBased Aerosol Optical Depth Data
    Estimating Long-Term PM10-2.5 Concentrations in Six US Cities Using Satellite-Based Aerosol Optical Depth Data
    Adar SD ;
    Dorman M
    2022/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    A major challenge in assessing the health risks of PM10-2.5 is the limited ground-level measurement data from which to estimate exposure. This is especially problematic for studying long-term PM10-2.5 health effects since PM10-2.5 is more spatially variable than PM2.5 or PM10, particularly in urban areas. Fortunately, Aerosol Optical Depth (AOD) da ...

    2022/02/27 | National Institute for Occupational Safety and Health (NIOSH)
    Respirable rock dust poses serious long-term health effects to workers in mining and tunneling underground hard rock environments. When inhaled, respirable silica particles commonly found in quartz and other minerals will scar sensitive lung tissue and cause irreversible lung diseases. Characteristics such as concentration, type of mineral, particl ...

    A Network Model Analysis of an Unconventional Gas Well Breach Above an Underground Coal Mine [2022]
    Dougherty H ;
    Kimutis R
    2022/02/27 | Mining Publications
    Gas wells have often intersected mining resources, but unconventional shale well drilling has more recently challenged mines to balance the risk of interaction due to higher pressures and larger quantities of gas. Full extraction mining, such as the longwall method, induces ground movement that may influence the casings if wells are drilled within ...
