Risk Evaluation and Development of Soil Quality Level of Cd and Pb using Biotic Ligand-Based Model in Former Smelter Area
In this study,the risk of Cd and Pb in a former smelter area was evaluated using the toxicity predicting tool based on the Biotic Ligand Model and the sensitivity of Vibrio fischeri.The evaluated toxicities show that all the areas on the site have high risks due to the presence of Cd in soil,while Pb in soil does not pose risk.The site specific soil quality levels (SQLs) of Cd and Pb were suggested based on the same tool,and compared with the Korean soil regulatory level.The suggested SQLs of Cd were much lower than the Korean soil regulatory level; while the suggested SQLs of Pb were higher than the regulatory level.The total concentrations of Cd or Pb in soil determined and the suggested SQLs were compared.At all areas of the site,the total concentration of Cd in soil exceeded the site specific SQL; however,for Pb,the risk pollution level exceeded 1 only for one sample among 51 samples.The huge difference of suggested SQLs and the present standards of Cd could be explained by the low sensitivity of V.fischeri for Cd.
