• Real-Time Estimation of Elemental Carbon Emitted from a Diesel Engine
  8/1/2007 - Peer reviewed journal articles
  This paper describes a simple, inexpensive, dependable, and field portable method for estimating the mass concentration of elemental carbon exiting the tailpipe of a diesel engine using a direct reading photometer in underground mines.
• Explosion Temperatures and Pressures of Metals and Other Elemental Dust Clouds
  7/1/2007 - Peer reviewed journal articles
  NIOSH's Pittsburgh Research Laboratory conducted a study of the explosibility of various metals and elemental dusts, focusing on explosion temperatures. The data will aid in evaluating explosion hazards in the minerals/metals processing industries.
• The Fate of Metal (Fe) During Diesel Combustion: Morphology, Chemistry, and Formation Pathways of Nanoparticles
  4/1/2007 - Peer reviewed journal articles
  This report describes an investigation in which NIOSH used iron-doped diesel fuel to generate metal-bearing diesel particles and a subsequent analysis of the particles using transmission electron microscopy (TEM) and energy-dispersive spectroscopy (EDS).
• Effects of Trace Metals on Particulate Matter Formation in a Diesel Engine: Metal Contents from Ferrocene and Lube Oil
  10/1/2006 - Peer reviewed journal articles
  In this study, the single particle mass spectrometer (SPMS) was applied to explore the composition of DPM, namely the origin of metals and size preferences of metals originating from metallic fuel additives and lube oil.
• Explosion Temperatures of Metals and Other Elemental Dust Clouds
  8/1/2006 - Conference papers
  NIOSH conducted a study of the explosibility of various metals and other elemental dusts dispersed in air to aid in understanding dust cloud combustion and in evaluating the explosion hazards in the minerals and metals processing industries.
• The Effects of Water Emulsified Fuel on Diesel Particulate Matter Concentrations in Underground Mines
  6/1/2006 - Conference papers
  The ambient diesel particulate matter (DPM) concentrations (at the intakes and exhausts of the mine) was evaluated as an entire vehicle fleet of a stone mine switched from using 35% biodiesel to a water-emulsified fuel (PuriNOx).
• Implementation of Diesel Particulate Filter Technology in Underground Metal and Nonmetal Mines
  6/1/2006 - Conference papers
  This paper provides detailed analysis of some of those challenges and short overviews of several projects launched by the NIOSH Pittsburgh Research Laboratory in an attempt to provide the underground mining industry with more adequate DPF systems.
• Instrumentation for Diesel Particulate Matter Emissions Research
  6/1/2006 - Conference papers
  The results of a series of tests in an underground mine were used to evaluate several measurement methods that are currently used to characterize particulate matter emitted by diesel-powered equipment. This paper presents an overview of these techniques...
• A New Method to Clean Dust from Soiled Work Clothes
  6/1/2006 - Conference papers
  Dust from worker's clothes has been shown to be a problematic source of personal dust exposure. A recently completed effort between NIOSH and Unimin Corp. has resulted in a quick and effective way to clean worker clothing. Field testing indicated that t...
• DEEP Project on Evaluation of Diesel Particulate Filters at Inco's Stobie Mine
  6/1/2006 - Conference papers
  The objective of the Diesel Emissions Evaluation Program (DEEP)-sponsored project at Inco Ltd.'s Stobie Mine was to conduct a long-term field evaluation of diesel particulate filter (DPF) systems available to the underground mining industry. Some of the...
