Abstract: | This paper describes the roles that dose-response andbiogeochemical-cycle models play in the comparative and integratedassessment of several atmospheric issues. The two approaches aredescribed briefly, as they are commonly used, and as they might beapplied when multiple stressors and receptors, and when interactingcycles, respectively, are involved. Examples are drawn from thecarbon and sulfur cycles to demonstrate how knowledge of a cycleprovides a useful link among various current pollution issues. Possibleinteractions and some shortcomings of the two approaches are given,leading to suggestions for the appropriate use of the two tools forscientific analysis and policy development for the various air issues. |
