Abstract : The evaporation of sulfur mustard from concrete was studied as a function of temperature, drop size, and air flow rate using the same instrumentation as prior studies on glass and sand. The evaporation rate increased with higher temperature, drop size, and wind speed; an empirical equation was determined that would allow for the calculation of the evaporation rate given the atmospheric conditions. The data collected provide input for the validation of empirical and physics-based models on the evaporation of agent designed by other authors. Comparisons with the evaporation rates of sulfur mustard from glass and sand are given.
