Abstract: Many atmospheric contaminants decay or react in the atmosphere. in situations such as the diffusion of radioactive contaminants, certain chemical pollutants and viable microorganisms, a first-order decay rate is considered ...

Abstract: A Gaussian model for continuous elevated sources is developed which uses a continuous distribution of ground-level sources to replace the use of the image source. For the case of Fickian diffusion with uniform wind, this ...

Abstract: A modification of the Gaussian plume model is proposed for the deposition of fine and heavy particulates and gases. It combines a downward-sloping plume to account for settling and the assumption of constant deposition ...

Abstract: Plume models were developed to predict the concentration due to a nonbuoyant release from a source whose strength decreases exponentially with time of a pollutant that reacts in the atmosphere at a first-order rate. Models ...
