Pyle, B. AND J. McCain. CRITICAL REVIEW OF OPEN SOURCE PARTICULATE EMISSION MEASUREMENTS: FIELD COMPARISON. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-86/072 (NTIS PB86239787), 1986.
Description:
The report gives results of a review of sampling and analytical procedures used by various testing firms to quantify particulate emissions from open sources; e.g., roads and storage piles. Seven firms, who account for nearly 100 percent of all open source data in the literature, described their current sampling and analytical procedures. Five of these firms then participated in a simultaneous side-by-side field test on a simulated unpaved road at a major steel plant. Each firm independently measured the particulate emission concentrations produced by roadway traffic. These measurements produced not only the particle-size dependence of the emissions but also the concentrations as functions of the distance above the road surface. The results for each firm were expressed as emission factors for total particulate and the mass fractions of the particulate with sizes <20, <15, <10, and <2.5 micrometers diameter. Based on an analysis of the results, it was found that all five profiling systems could produce equivalent results in terms of total emissions.
