    Abstract

    A computer program was developed for the assessment of human exposure to airborne pesticides in the work place, such as a greenhouse or a chemical production plant. The program considers various aspects of aerosol physics including accounting for sources, transport, deposition, and evolution of the size distribution of aerosol materials. In addition, it addresses phase transition phenomena and photolysis. It evaluates level of exposure to airborne particles based on arbitrary schedule of worker activities. Results of model calculations using the computer code show the importance of source strength, droplet size, air flow patterns, applicator activities and location, and atmospheric conditions.
