Managing human exposure and health risks: An integrated approach and the role of uncertainty
Human populations contact environmental pollutants through food,water, and air in varying amounts each day throughout a lifetime. A realistic strategy for managing health risks of environmental contaminants therefore requires a comprehensive and integrated approach. Using examples for exposure to contaminants in potable water and to contaminants transferred from air to food, this paper considers two important issues in exposure assessment -- the completeness of current exposure models and the treatment of uncertainty in exposure estimates. The results indicate that risk managers should consider the potential for multiple pathways, avoid risk assessments derived from single value estimates, be aware of the uncertainty in risk estimates, and include this awareness in their decisions.
