Special Report: Research Directions to Improve Estimates of Human Exposure and Risk from Diesel Exhaust. Cambridge, MA: Health Effects Institute, 2002 Apr; :39-40
A Special Report of the Institute's Diesel Epidemiology Working Group. The Diesel Epidemiology Working Group was formed in the fall of 2000 to (1) review reports from 6 diesel feasibility studies funded by HEI to provide information on potential study populations and on exposure assessment methods; and (2) onsider the results of the feasibility studies and other ongoing research in order to develop a new research agenda to seek better information for quantitative risk assessment of lung cancer and other chronic diseases that may result from exposure to diesel exhaust. The 6 feasibility studies described in this report were funded by HEI to provide insight about whether a new retrospective or prospective epidemiologic study could provide data to improve estimates of cancer risk from exposure to diesel exhaust, and about whether new methods of exposure analysis would allow us to reevaluate older epidemiologic studies. This study by Dr David Kittelson and colleagues (Measurement of Diesel Aerosol Exposure: A Feasibility Study) evaluated the feasibility of measuring EC, mass of black carbon, and surface area, number concentration, and size distribution of airborne diesel PM in 3 populations occupationally exposed to relatively low levels of diesel exhaust. The populations were bus drivers, parking garage attendants, and mechanics. The investigators used several methods to measure diesel PM. The different instruments and methods gave results that were consistent among the methods, detecting diesel PM at the low end of typical occupational exposures (which are, in turn, at the high end of typical ambient exposures). The 3 occupational groups had similar exposures to airborne diesel PM when analyzed by mass, but different exposures when analyzed by particle surface area and particle number distributions.
