A study was carried in three different local markets in Bangalore city to check the concentration of heavy metals in tubers. The bio-accumulation of heavy metals was studied in tubers such as potato, sweet potato, elephant yam, raddish, carrot, ginger, beetrooot were collected from three different markets of Bangalore city (HAL Market, Russel Market, Yellahanka Market). In tubers unpeeled showed relatively more accumulation in comparison with peeled one. This study concludes that the unpeeled tuber samples showed more accumulation of heavy metals than the peeled samples and the elevating levels of heavy metals in tubers having potential health hazards to consumers of locally produced food items.
