• Real-time Diesel Particulate Monitor for Underground Mines
  6/1/2013 - Peer reviewed journal articles
  An article evaluating a commercial instrument developed based on NIOSH research for measuring EC concentrations in real time.
• Mutagenicity of Biodiesel or Diesel Exhaust Particles and the Effect of Engine Operating Conditions
  3/1/2013 - Peer reviewed journal articles
  A study of the mutagenic potential of diesel emissions from neat and blended soy-based fatty acid methyl ester (FAME) biodiesel compared to ULSD PM using different engine operating conditions and exhaust aftertreatment configurations.
• Effects of a diesel particulate filter regeneration process on aerosols in an underground mine
  12/1/2012 - Peer reviewed journal articles
  This study was conducted to evaluate the effects of a diesel particulate filter (DPF) regeneration process on the concentrations and size distributions of aerosols in an underground mine.
• Toward developing a new occupational exposure metric approach for characterization of diesel aerosols
  12/1/2012 - Peer reviewed journal articles
  In this study, the current exposure metric and two additional metrics, the surface area and the total number concentration, were evaluated by conducting simultaneous measurements of diesel ultrafine aerosols in a laboratory setting.
• Field Evaluation of Diesel Particulate Matter Using Portable Elemental Carbon Monitors
  6/1/2010 - Conference papers
  NIOSH has developed a portable elemental carbon monitoring device for use in underground mines. This paper discusses a variety of ways that this instrument has been used to help lower DPM concentrations and exposure to DPM in active mines.
• The Effects of Passive Diesel Particulate Filters on Diesel Particulate Matter Concentrations in Two Underground Metal/Nonmetal Mines
  6/1/2010 - Conference papers
  In this study, NIOSH measured the atmospheric concentrations of DPM and gases in two mines in order to evaluate the effects of various control strategies on the atmospheric DPM concentrations.
• Mutagenicity of Diesel Exhaust Particles from an Engine with Differing Exhaust After Treatments
  1/1/2010 - Peer reviewed journal articles
  This paper discusses the results of a study to investigate the effects of engine operating conditions and exhaust aftertreatments on the mutagenicity of diesel particulate matter (DPM) collected directly in an underground mine environment.
• Controlling and Monitoring Diesel Emissions in Underground Mines in the United States
  11/1/2009 - Conference papers
  The Pittsburgh Research Laboratory (PRL) of NIOSH conducts research to evaluate control technologies and monitoring instrumentation that can be used to reduce the diesel particulate matter (DPM) exposure of mine workers.
• Real-Time DPM Ambient Monitoring in Underground Mines
  11/1/2009 - Conference papers
  The paper discusses how the Diesel Particulate Matter (DPM) monitors have performed within the underground mine environment in evaluating DPM during the various phases of longwall moves.
• Field Evaluation of a Passive Diesel Particulate Filter at a Limestone Mine
  4/1/2009 - Peer reviewed journal articles
  In this study, the operators of a limestone mine retrofitted a loader used for clean-up operations with a passive DPF that was lightly catalyzed and used a fuel additive to initiate regeneration at low exhaust temperatures.
