This page provides a description and a link to a "Hazardous Air Pollutant Exposure Model (HAPEM)" modeling tool that can be used for modeling exposure levels or information needed in exposure assessment.

Short description

The HAPEM model 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 relationship data, population data, and human activity pattern data to estimate an expected range of inhalation exposure concentrations for groups of individuals.
