To inform the public.
Description:
Research has been conducted on aerosol emission rates during various activities as well as aerosol transport into the breathing zone under idealized conditions. However, there has been little effort to link the two into a model for predicting a person’s breathing zone concentration. The research objective was to link aerosol emission rates from a surface during a specific activity to the resulting breathing zone concentration using a Monte Carlo simulation on an aerosol and fluid dynamic theory based model. A successful model will improve our understanding of the links between emissions characterization environmental concentrations and human exposure in the overall exposure risk paradigm.
