The contents of five heavy metals such as lead, cadmium, zinc, copper and manganese in soil and vegetables collected from four sites in Busan district with composite sampling method were determined with ICP emission spectrometer. The ranges of their contents in soil were lead, $1.65sim4.36ppm;$ cadmium, $0.05sim0.09ppm;$ zinc, $6.33sim11.09ppm;$ copper, $0.44sim1.35ppm;$ manganese, $8.40sim19.39ppm$, respectively. These contents were lower than the Clarke number. The range of heavy metal contents in four vegetables such as lettuce, radish and its roots, spinach and cabbage were lead, $0.09sim0.48ppm;$ cadmium, $0.01sim0.08ppm;$ zinc, $1.81sim14.62ppm;$ copper, $0.14sim1.87ppm;$ manganese, $0.71sim14.5$ 5ppm with the order of Zn(7.30 ppm)>Mn(4.35 ppm)>Cu(0.53 ppm)>Pb(0.19 ppm)>Cd(0.04 ppm) in average contents. The average transfer ratio of metals from soil to vegetables was order of Zn(77.8 %)> Cd(37.5 %)>Cu(34.5 %)>Mn(18.6 %)>Pb(6.7 %). In case of the same cultivating soil, the transfer ratio could be expected to the order of spinach<radish<cabbage<lettuce for copper, $lettuce{approx}cabbage$<radish<spinach for manganese, respectively.
