The health risk assessment of chemical emissions from industrial facil
ities requires the mathematical modeling of a variety of processes, in
cluding transport and fate of chemicals in and between various environ
mental media, population exposure to these chemicals, their associated
doses, and health effects. Several models are presently available to
address these different components of the health risk assessment. Exis
ting models were reviewed and recommendations are provided for the sel
ection of models suitable for screening and refined risk assessments.
This article reviews mathematical models for estimating population exp
osure to chemicals.
