A stabilization technique was applied to immobilize lead (Pb) in contaminated soils obtained from army firing ranges using waste oyster shells. Both natural waste oyster shells (NOS) and pretreated oyster shells (POS) were used as the main stabilizing agents. The pas were roasted at a high temperature to activate quicklime from the calcite in the shells. The treatments were performed with two different particle sizes (2 ㎜ 0.853 ㎜) at a curing period of 8 days. Pb leaching tests from both NOS and pas stabilized soil samples cured for 28 days were evaluated using the Korean Standard Test (KST) method (01N Hel extraction). The treatment results using oyster shells of 2 ㎜ in size, after 28 days of curing, indicated that the pas treatment was more effective than the NOS treatment at stabilizing the Pb in the contaminated soils. All the NOS treatments failed to meet the Korean warning standard of 100 ㎎/㎏. However, less than 50 ㎎/㎏ of Pb leached (> 99% Pb reduction) from the 15 wt% and 20 wt% pas stabilized soils, after 28 days of curing. Moreover, the particle size reduction of NOS using the 0.853 ㎜ size showed better performance in reducing Pb leachability while the particle size reduction of pas showed no significant effects on the reduction of Pb leachability. Overall, it could be concluded that the pas treatment was significantly effective at immobilizing the Pb in the contaminated soils and the pas could be utilized as a cost effective stabilizing agent.
