Title: LONG-TERM EFFECTS OF DEICING SALT ON THE ROADSIDE ENVIRONMENT: PART I: FORESTRY

Availability: Find a library where document is available Abstract: The effects of winter road maintenance constitute a complex system of many interrelationships. One of these relationships is the effect of deicing salt on vegetation. Such effects are described in the form of a DPSIR (Driving force, Pressure, State, Impact, Response) model. According to the model, the need for transportation (D) leads to a roadside exposure to salt (P), which alters the state of the vegetation (S), thereby leading to different kinds of impacts (I), which may require some kind of response (R). The impacts of deicing salt on roadside vegetation are grouped into three spheres of interest: the public, landowners, and ecology. In Sweden, the Environmental Code requires that the Swedish National Road Administration work to understand how these complex systems operate and to take active measures to prevent damage to human health and the environment. This mandate requires knowledge of each DPSIR model element as well as the relationships between the elements. So far, research on this topic has resulted mainly in model indicators that cannot be used easily by road administrators. It is therefore of great importance to be able to assign adequate indicators to all levels of the model and to monitor these indicators on both a temporal and spatial scale that facilitates responding with the proper actions. To establish an environmentally sustainable winter road maintenance system, it is also crucial to establish the long-term tolerance limits of human health and nature as the base for salting strategies.
