Atomic Absorption Spectrophotometer model 210 VGS was used for the analysis using a standard procedure. The concentration of Pb in Spinach, Jute Leaves and Tomatoes ranged from 2.10 mg/kg – 3.00 mg/kg which are all above the Minimum permissible limits (2.00 mg/kg) of World Health Organization (WHO, 1996).
