In order to investigate the pollution of heavy metal in soil, chinese cabbage and radish collected from Singal interchange (highway area), Anyang stream, Jungryang stream (stream basin) and Chunchun dong, Suweon (non-polluted area), this study was carried out from July to October in 1983. The contents of cadmium, copper, lead, and zinc were determined by atomic absorption spectrqphotometry. Generally in soil, the contents of heavy metals in highway area were lower than that in Anyang stream and Jungryang stream, but higher than that in non-polluted area. (Chunchun dong, Suweon). The vegetable samples of highway area were more polluted compared with that of Chunchun dong, Suweon. The contents of heavy metals in radish were higher than that of chinese cabbage and radish leaves were more polluted than roots.
