Integrating Exposure and Exposure–Response

The primary task of risk characterization is to integrate the exposure estimates from the

analysis of exposure with the exposure-response relationships from the analysis of effects to

estimate the nature and magnitude of risks. In effect, response is estimated by solving the

exposure-response function for the exposure estimate. In most assessments, this task has

been performed by simple methods that require little thought. However, as more attention

is paid to varia bility and uncerta inty (Chapter 5), probabil istic methods are be coming more

common.
