AFTOX can be used to model the impacts from point, area, and liquid spill sources. For each source type, the release can be continuous, finite, or instantaneous in duration. For liquid spills, AFTOX can calculate the evaporation rate from the pool using one of three evaporation models (Vossler, Shell, or Clewell), in addition to providing the downwind plume concentrations. For each release, AFTOX assumes the plume distribution is Gaussian in the downwind and crosswind directions. The model uses Pasquill-Gifford dispersion coefficients with modifications to account for a user-specified averaging time. AFTOX is included in the BREEZE HAZ DISPERSION and BREEZE HAZ PROFESSIONAL product suites.	HAZ Flash Demo HAZ Dispersion HAZ Professional
