Hydrogen cyanide in ambient air near a gold heap leach field: Measured vs. modeled concentrations

The MERSADE (European Union) project: Testing procedures and environmental impact for the safe storage of liquid mercury in the Almadén district, Spain

“…The models were specifically developed to simulate air pollution resulting from emissions from industrial sources and simulate the impact of a contaminating source such as emissions from mineral dumps, contaminated soils, etc. (e.g., Orloff et al, 2006). The models use meteorological data averaged over 1-h periods of time to estimate 1h steady-state concentrations of air contaminants.…”

Identification and elucidation of anthropogenic source contribution in PM 10 pollutant: Insight gain from dispersion and receptor models

“…It assumes a Gaussian plume distribution in the vertical and horizontal direction for stable boundary layers; and Gaussian in the horizontal and bi-Gaussian in the vertical for convective boundary layers (Barrat, 2001). This model is typically used for large areas or stationary sources (Orloff et al, 2006). It is a steady-state plume model which assumes that concentrations at all distances during an hour of modeling are governed by the temporally averaged meteorology of the hour.…”

Odor Load Investigation for a Pharmaceutical Plant by Open Path Fourier Transform Infrared (OP-FTIR)/Environmental Protection Agency Regulatory Dispersion Model (AERMOD)

“…The coefficient of determination (R 2 ) of 0.9687 indicated that the modeled results are adequate to represent the observed results. With the slope of 0.9072, the modeled result from AERMOD is slightly under-predicted for the observed odor index, but is still acceptable based on a previous report using AERMOD (Venkatram et al, 2004;Kumar et al, 2006;Orloff et al, 2006).…”
