—The content of copper, lead, cadmium, and zinc on tissues of Lycopersicon esculentum Mill. grown around a contaminated area. Rhizomes showed a high content of the metals, followed by the leaves, and finally the stems, which had the lowest content of the metals. Lead concentrations in rhizomes, stems, leaves were 430 mg/Kg, 180 mg/Kg, and 120 mg/Kg, respectively, while copper concentrations were 810 mg/Kg, 463 mg/Kg, and 250 mg/Kg, respectively. In contrast, cadmium and zinc concentrations were lower and varied from 30 mg/Kg on rhizomes, 58 mg/Kg on leaves, and 46 mg/Kg on stems for cadmium, and the content of zinc found ranged from 31 mg/Kg on rhizomes, 35 mg/Kg on stems, and 42 mg/Kg on leaves. Soil concentrations were high in site 3 for lead and copper, 4,621 mg/Kg and 5,631 mg/Kg, respectively; lower concentrations were found for cadmium and zinc, 223 mg/Kg and 57 mg/Kg, respectively. As expected, those sections which contained higher levels of heavy metals in the soil also showed to have higher heavy metal uptake by various parts of Lycopersicon esculentum Mill. These data demonstrate Lycopersicon esculentum Mill. ability to uptake copper and lead, and to some extent cadmium and zinc, from heavy metal contaminated soils.
