摘要: The contents of lead (Pb), copper (Cu), chromium (Cr), zinc (Zn) and cadmium (Cd) in various leafy vegetables viz., spinach, coriander, lettuce, radish, cabbage cauliflower grown an effluent irrigated fields the vicinity industrial area Faisalabad, Pakistan were assessed using atomic absorption spectrophotometer. concentrations Pb, Cu, Cr, Zn Cd leaves, stems roots found to be 1.1331−2.652, 1.313-2.161, 1.121-2.254; 0.252-0.923, 0.161-0.855, 0.221-0.931; 0.2170.546, 0.376-0.495, 0.338-0.511; 0.461-1.893, 0.361-0.874, 0.442-1.637; 0.033-0.073, 0.017-0.061, 0.011-0.052 mg kg -1 on dry matter basis, respectively. Zn, Pb below recommended maximum acceptable levels proposed by Joint FAO/WHO Expert Committee Food Additives. leaves cabbage, cauliflower, radish coriander contained higher Cu (0.923 ), (0.073 Cr (0.546 (1.893 ) (2.652 as compared other parts each vegetable. High heavy metals analyzed present analysis different might related their concentration soils with waste water.
