Abstract

The principles of the interaction between gaseous air pollutants and ecosystems are investigated using a pharmacokinetic model. This model illustrates the importance of pollutant flux determinations by measurements and/or by modeling in order to provide a description of the adequate dose entity. It serves as a mechanistic base for the present discussion of flux-based versus concentration-based air quality guidelines. Consequently, the results obtained from chamber experiments can onlybe transferred to ambient conditions, if the function relating fumigation concentrations to absorbed fluxes is established. Adequate dose-response relationships for airborne pollutants and plant/soil systems presuppose a combination of flux measurements, free-air exposure systems and Soil-Vegetation-Atmosphere Transfer models.
