2/1/2007 - Peer reviewed journal articlesTo evaluate how elemental carbon (EC), a surrogate of diesel particulate matter (DPM), predicts DPM, measurements of total carbon (TC) and EC were taken away from potential interferences in four underground metal/nonmetal mines during production.
-
12/1/2004 - Peer reviewed journal articlesA commercial version of the BOM impactor, called the DPM Cassette, was recently introduced by SKC®. Tests were conducted to evaluate the performance of the DPM Cassette for measuring diesel-source elemental carbon in the presence of coal dust.

3/1/2015 - Peer reviewed journal articlesAn article describing an investigation of the relationship between total carbon and elemental carbon from diesel particulate matter samples to determine if a single conversion factor can be used for all metal/nonmetal mines.
-
12/1/2012 - Peer reviewed journal articlesIn 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.

6/1/2010 - Conference papersNIOSH 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.
-
6/1/2008 - Conference papersThis paper describes a portable device developed by NIOSH for measuring levels of elemental carbon in real time.
-
6/1/2006 - Conference papersElemental carbon (EC) is used as a surrogate for regulating the exposure to diesel particulate matter (DPM) of underground metal/nonmetal miners. Currently, EC represents DPM well in underground mines. Some control technologies have been shown to possib...
