Precipitation Scavenging of Organic Contaminants

Abstract

The EPAEC gas washout model has been applied to the organic tracers ethylacetoacetate and diethylamine. This model uses source strength, vapor solubility and basic meteorological parameters to estimate the tracer concentration in downwind rain samples. A detailed error analysis has identified poorly defined tracer solubility as the major source of measured discrepancy with predictions. Field results have also been used to calculate the fractional washout of the vapor per kilometer from the source. The results together with existing diffusion models may be used to estimate the vapor concentrations of these materials along a plume trajectory.
