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.
-
1/1/2011 - Book chaptersWhile approaches to workplace aerosol measurement differ; this book chapter emphasizes the basic sampling philosophies and methods used routinely in the workplace and the application of direct-reading monitors.
-
7/1/2010 - Peer reviewed journal articlesAn air quality survey was conducted at a precious metals refinery in order to evaluate worker exposures to airborne metals and to provide detailed characterization of the aerosols.
-
6/1/2010 - Peer reviewed journal articlesResearchers at NIOSH are developing methods for characterizing ultrafine aerosols in workplaces. One method includes the detailed analysis of collected particles using electron microscopy (EM).
-
6/1/2008 - Conference papersThis NIOSH study was conducted to establish the effects of a diesel particulate filter (DPF) system with sintered metal substrate on the concentrations and size distributions of nano and ultrafine aerosols and concentrations of nitric oxides in undergro...

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.
-
10/1/2007 - Peer reviewed journal articlesThe primary goal of this study was to investigate the formation of combustion-generated particles derived from lubrication oil in the absence of fuel-produced soot.
-
10/1/2007 - Conference papersA paper describing tests conducted in the NIOSH Diesel Laboratory at the Lake Lynn Laboratory experimental mine, a facility developed to allow evaluation of control technologies directly in an underground environment.
-
4/1/2007 - Peer reviewed journal articlesThe objective of this paper is to compare the results among (1) a NIOSH published standard to determine the mass of EC and OC on filter samples, (2) the aethalometer, which uses light extinction to measure "black carbon" or BC, and (3) measuring particl...
-
4/1/2007 - Conference papersThis paper identifies and characterizes nanometer and ultrafine aerosols emitted by diesel engines in the underground environment and evaluates the effects of selected contemporary control technologies.
