True Pb intake = (200 g × 1.60 mg·kg-1) + (200 g × 0.56 mg·kg-1) + (200 g × 3.89 mg·kg-1)  =  1210 mg·kg-1

True Cd intake = (200 g × 0.27 mg·kg-1)  + (200 g × 0.25 mg·kg-1) + (200 g × 0.23 mg·kg-1)  =  150 mg·kg-1

True Ni intake = (200 g × 1.30 mg·kg-1)  + (200 g × 0.66 mg·kg-1) + (200 g × 0.32 mg·kg-1) =  456mg·kg-1

ayearly intake of vegetables(Green leaf, fluted pumpkin and curry leaf) multiplied by concentration of heavy metal contaminant in each vegetable.
