Human Exposure Modeling - Hazardous Air Pollutant Exposure Model (HAPEM)

The HAPEM has been designed to estimate inhalation exposure for selected population groups to various air toxics. Through a series of calculation routines, the model makes use of ambient air concentration data, indoor/outdoor microenvironment concentration relationships, population data, and human activity pattern data to estimate an expected range of inhalation exposure concentrations for groups of individuals.

Three versions of this model are currently available: HAPEM5 and HAPEM6, and the latest version, HAPEM7.
