As a subfield of public health, environmental health is concerned with evaluating and ameliorating the effects of people on the environment and the effects of the environment on people. Separating hazards from risks, and characterizing the magnitude, likelihood, and uncertainty of risks is at the heart of environmental health in the 1990s. To this end, a full range of data is needed, including data that characterize the distribution of hazards, the population potentially at risk, and the contact between people and pollution that creates the risk. Several government-sponsored data systems contain information on a range of exposure estimators. The challenge is to develop meaningful, properly validated models to identify public health needs and evaluate public health programs.
