In order to evaluate the pollution potential of agricultural crops after the construction of Onsan Industrial Complex (non-ferrous metal refineries), concentrations of hazardous heavy metals were analyzed for crop samples (rice, barley, soybean, vegetables and fruits) grown near the Complex in 1978. Although a slight difference was found among the kinds, parts and growing regions of the crops, no definite tendency was observed. The mean/maximum concentrations of crop samples were 0.23/4.0ppm As, 0.4/1.2 ppm Cd, 4.88/12.7ppm Cu, 0.09/0.4 ppm Hg, 3.86/5.0 ppm Pb and 41.3/105 ppm Zn, which may serve as the natural background data for this region.
