The transfer of heavy metals from soil to plants under conditions of soil pollution is a process of significant importance, because it is considered as the main pathway of human exposure to heavy metal through foodchain. BioConcentration Factor (BCF) is an indicator of heavy metal mobility in soils and a factor that quantifies bioavailability of heavy metals to agricultural products. BCF is defined as ratio of heavy metal concentration in vegetable (dry weight) to that in soil (dry weight). This study was carried out to measure the transfer ability of Arsenic (As), Cadmium (Cd), and Lead(Pb) from soil to agricultural products. We investigated heavy metals (As, Cd and Pb) concentrations in 8 agricultural products (sesame leaf, spinach, chinese cabbage, lettuce, chinese chive, ginseng, deodeok, balloonflower) as well as in cultivated soils. BCF for heavy metals from soil to vegetables for three elements including As, Cd, and Pb was calculated based on total soil concentration. The result showed that BCF values was calculated average 0.006∼0.026 (As), 0.015∼1.395 (Cd), 0.015∼0.076 (Pb). The mean BCF value was the highest as ginseng 0.026 in As, balloonflower 1.395 in Cd, chinese chive 0.076 in Pb. It were dependent on the vegetable type and species. Root vegetables are showed higher than leafy vegetables in As and Cd. We found that BCF are useful in predicting the uptake of heavy metals. Further study of uptake and accumulation mechanism of toxic metals by agricultural products will be required to assess the human health risk associated with soil contamination.
