Meeting these new challenges requires a public health approach (Goldstein 1995), including an enhanced scientific capability to measure exposure in the target human or ecosystem rather than at the end of the pipe, a better understanding of the relation between external dose and target organ toxicity, and translation of advances in analytical chemistry and molecular biology to develop better biological indicators of exposure, effect, and susceptibility.
