MODELING EXPOSURE OF THE DUTCH POPULATION TO AIR-POLLUTION

The AirPEx (air pollution exposure) model is a mathematical model to e stimate the inhalatory exposure of humans to air pollution. The model quantifies individual and population exposures using data from air qua lity time series and activity pattern surveys. This paper presents the basic exposure concepts of the model, including contact, actual expos ure concentration, intake rate, and standardisation. A case study incl uding the exposure to ozone of the Dutch population in the 1991 summer demonstrates the application of the model. (C) 1998 Elsevier Science B.V. All rights reserved.
