In the past, no scientifically valid approach for determining the exposures of an urban population to a pollutant was available. Recently, EPA successfully field tested two separate but complementary approaches for determining population exposures to air pollution: (a) direct measurement of exposure profiles of a representative random sample of the population with personal exposure monitors, and (b) an indirect approach which combines human activity pattern data with micro-environmental concentration data to estimate exposure profiles. In the winter of 1982-83, the two approaches were field tested. This effort provides a rich human exposure data base and a methodology that can be applied to other pollutants and other urban areas.
