Swamp cabbage was analyzed in the roots, stems and leaves at the age of 2 weeks to 4 weeks. The levels of Pb 2+  ion was determined by dry destruction method, then measured by atomic absorption spectrophotometry. Pb 2+  ion was accumulated on the ground kale plants. The highest levels of Pb 2+  ion was contained in the roots of ground kale plants on media cropping which added 1.5 L of leachate at the age of 3 weeks of 2.0642 mg / kg wet weight. The lowest level of Pb 2+  ion was contained in the leaves of control plants at the age of 2 weeks that was 0.0177 mg / kg wet weight.
