• Evaluation of the Approach to Respirable Quartz Exposure Control in U.S. Coal Mines
  2/1/2012 - Peer reviewed journal articles
  The performance of the current regulatory approach was found to be lacking due to the use of a variable property - quartz content in airborne dust - to establish a standard for subsequent exposures.
• Identifying Sources of Respirable Quartz and Silica Dust in Underground Coal Mines in Southern West Virginia, Western Virginia, and Eastern Kentucky
  4/1/2009 - Peer reviewed journal articles
  This paper discusses the geochemical analyses which were applied in an effort to identify the specific source rock of respirable quartz dust in coal mines.
• Implementing Infrared Determination of Quartz Particulates on Novel Filters for a Prototype Dust Monitor
  5/1/2008 - Peer reviewed journal articles
  This article describes the results from analysis of open-face samples which suggest that the new formulations for PDM filters have fully addressed the analytical obstacles that existed with the original filter design.
