Abstract: Vegetable samples from one of the main whole sale markets of Bangalore city were collected over two yearsand analysed for heavy metals such as Cd, Pb, Cr and Ni. Heavy metal content of vegetables ranged from 0.24to 2.54 mg Cd kg-1, 2.16 to 10.40 mg Pb kg-1 , 3.08 to 16.2 mg Cr kg-1and 1.66 to 11.52 mg Ni kg-1. Leafy vegetablesaccumulated higher concentration of heavy metals followed by root vegetables. Fruit vegetables accumulatedthe lowest content of heavy metals. But the heavy metal content of all the vegetables crossed the safe limitspermitted for human consumption to a far greater extent except that Cd content of root and fruit vegetableswere within the safe levels. Among leafy vegetables, amaranthus and palak accumulated the highest content ofall the four heavy metals studied.
