Abstract [en]

The environmental model is a submodel in the Swedish winter maintenance management system, the Winter Model. The Winter Model will make it possible to assess the most important effects and their monetary value of changes in winter maintenance strategies and operations in Sweden. The effects are assessed for road users, road administrators, and the environment. Modeling the impact of the use of chemical anti- and deicing on roadside environment requires knowledge of the roadside exposure to salt, the vulnerability or dose-response relationship of the modeled environmental subjects and, preferably, the “cost” of the following impacts. In this paper, research results from some recent field studies are used to illustrate how the transport mechanisms responsible for the roadside exposure to deicing salt is working under different weather conditions. In order to improve the current model describing the roadside exposure to salt for even better prediction, the occurrence of plowing actions is also suggested to be incorporated into the model. Further it is suggested that, if also the presumably small depositions of dry salt aerosol particles on larger distance are to be described, the transport mechanism of dry salt crystals, breaking up into small airborne fragments and transported by the wind is also to be incorporated into the model describing the roadside exposure to deicing salt. The results in this paper are beeing incorporated into the Swedish Winter Model.
