REVIEW OF MATHEMATICAL-MODELS FOR HEALTH RISK ASSESSMENT .5. CHEMICALCONCENTRATIONS IN THE FOOD-CHAIN

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 concentrations of chemicals in the food chain.
