Identification of an Accurate Soil Suspension/Dispersion Modeling Method for Use in Estimating Health-Based Soil Cleanup Levels of Hexavalent Chromium in Chromite Ore Processing Residues

Abstract: The primary health concern associated with chromite ore processing residues (COPR) at sites in Hudson County, NJ, is the inhalation of Cr(VI) suspended from surface soils. Since health-based soil standards for Cr(VI) will be derived using the inhalation pathway, soil suspension modeling will be necessary to estimate site-specific, health-based soil cleanup levels (HBSCLs). The purpose of this study was to identify the most appropriate particulate emission and air dispersion models for estimating soil suspensio… Show more

“…Once researchers began to consider human exposure in residential neighborhoods and on farms, field studies were designed that included potential or actual soil contamination, and they focused on quantifying the movement of resuspended, contaminated outdoor soil and road dust into indoor locations (46)(47)(48)(55)(56)(57)(58)(59)(60)(61). These studies were designed to examine the exposure and risk posed by toxicants deposited in the lungs of people living in zones potentially affected by point and area sources.…”

“…Since the publication of Scott et al, 1 the AP-42 model for particulate emissions from vehicle traffic over unpaved roads has been revised three times, with the most recent revision being in November 2006. 4 In addition, EPA has changed its choice of preferred models twice, first selecting the ISC3 to replace the ISC2 and, as of November 2005, selecting the American Meteorological Society/Environmental Protection Agency Regulatory Model (AER-MOD) as the preferred model.…”

“…4 In addition, EPA has changed its choice of preferred models twice, first selecting the ISC3 to replace the ISC2 and, as of November 2005, selecting the American Meteorological Society/Environmental Protection Agency Regulatory Model (AER-MOD) as the preferred model. 5 Furthermore, Scott et al 1 focused exclusively on modeling approaches for sites with vehicle traffic, and there has been recent interest in quantitatively evaluating the impact of particulate emissions due to wind erosion at COPR sites.…”
