Health-based risk assessments have uncertainties in many areas.
These uncertainties necessitate the use of assumptions which are required to err on the side of public health protection.
One source of uncertainty in risk assessment is the extent of human exposure to pollutants in various media such as air, water, soil, sediment and biota.
The pollutant concentrations in these media can be simulated through multimedia modeling of the complex physical, chemical, and biological processes that govern the fate and transport of the pollutants.
By reducing uncertainty (which often leads to conservatism) and providing realistic scenarios, multimedia modeling can help develop operating and control strategies which will minimize expenditures of societal resources without compromising environmental quality and public health.
