| Resumo: |
The purpose of this work is to study the potentially contaminating trace elements present in industrial waste that is discharged into the environment. The aim was to assess the parameters needed for it to be used in controlling the mobility of the potentially contaminating trace elements present in the residues. In this way were studied a refuse slag from Cia Siderúrgica Nacional – CSN). Even though this waste is considered relatively stable within the established standards set by current legislation due to its characteristics (Cd<0.5 mg/Kg, Pb<10 mg/Kg, Co<5 mg/Kg, Cu=61 mg/Kg, Cr=280 mg/Kg, Ni<1.5 mg/Kg, Zn=75 mg/Kg), there is so far no feasible alternative for its total reutilization. Bench-scale tests were performed whereby an acidified liquid to simulate the rainfall typical in highly industrialized regions was introduced in the cells that contained layers of the steelworks slag and clay minerals.
