Appraisal of heavy metals in different vegetables grown in the vicinity of an industrial area (original) (raw)

Pakistan Journal of Botany

Abstract

The contents of lead (Pb), copper (Cu), chromium (Cr), zinc (Zn) and cadmium (Cd) in various leafy vegetables viz., spinach, coriander, lettuce, radish, cabbage and cauliflower grown in an effluent irrigated fields in the vicinity of an industrial area of Faisalabad, Pakistan were assessed using atomic absorption spectrophotometer. The concentrations of Pb, Cu, Cr, Zn and Cd in the leaves, stems and roots of spinach, coriander, lettuce, radish, cabbage and cauliflower were found to be 1.
