6/1/2010 - Conference papersThis study examined the potential for coal mine roof bolter dust to be a source of a worker's exposure to respirable quartz.
-
5/1/2009 - Conference papersThis study shows a very good agreement between observations of partially burnt coal particles under a scanning electron microscopy (SEM) and floor dust samples, collected and analyzed using the alcohol coking test and SEM, to estimate flame travel.
-
7/1/2008 - Peer reviewed journal articlesIn this study, NIOSH investigated the effects of adsorption artifact on diesel particulate matter samples from occupational settings.
-
11/1/2007 - Peer reviewed journal articlesThis paper concludes a five-year program on research into the use of a portable X-ray fluorescence (XRF) analyzer for analyzing lead in air sampling filters from different industrial environments, including mining, manufacturing and recycling.
-
8/1/2007 - Peer reviewed journal articlesThis article examines the spatial variability of dust concentrations within a coal miner’s breathing zone and the impact of sampling location at the cap lamp, nose, and lapel.
-
7/1/2007 - Peer reviewed journal articlesResults indicate that particle sizes of mine coal dust in intake airways are finer and would require more incombustible matter to be effectively inerted than the 65% incombustible specified in current regulations.
-
6/1/2007 - Conference papersResults from underground dust surveys to identify current operating practices and the types of controls being used at longwall operations are presented as an update on longwall dust control technology and operating practices.
-
1/1/2007 - Peer reviewed journal articlesThe Thermo personal DataRam (pDR) is an instantaneous sampler that uses light-scattering technology to provide relative measures of airborne respirable dust. The pDR can be used in active and passive modes to measure respirable dust levels.
-
6/1/2006 - Conference papersThe relationship of dust concentrations measured by personal gravimetric samplers to those measured by the SKCDD, an affordable, person-wearable, real-time dust monitor.
-
6/1/2006 - Conference papersThe 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...
