The general approach to assement of risk from chemical contaminants in drinking water involves three steps: hazard identification, exposure assessment, and dose-response assessment.
Traditionally, the risks to humans associated with different levels of a chemical have been derived from the toxic responses observed in animals.
It is becoming increasingly clear, however, that further information is needed if risks to humans are to be assessed accurately.
Biologically based models help clarify the dose-response relationship and reduce uncertainty.
