Multidisciplinary approach to the environmental impact of steel slag reused in road construction
Given the large quantities of natural materials used daily in road building, it is necessary to find a way to reduce its adverse environmental impact. The modern approach is the application of new materials, usually waste ones, resulting in the preservation of natural materials but also the reduction of waste materials in dumping sites. In this study, steel slag as waste material in steel production is validated for its usage in road construction based on its potential adverse environmental impact through a multidisciplinary approach. Results of their leaching potential and impact on earthworms (Eisenia fetida) are presented. Chemical composition, dissolved oxygen, and pH value of leachate, radioactivity and mortality, and molecular biomarkers in earthworm E. fetida on two steel slag samples are analysed to fulfil present knowledge of steel slag environmental impact by a multidisciplinary approach. Results indicate that the analysed slags present no hazard for the environment if used in road construction (unbound pavement layers or embankment).
