In human, transfer factor of metals or bio-concentration factor is a key module to determine the level of exposure through food chain. In the following vegetables, i.e., Allium sativum, Solanum tuberosum and Daucus carota; BCF values was higher which were in line with previous study conducted in Lahore Pakistan (Mahmood and Malik, 2014). Higher transpiration rate to sustain the moisture level in plants in leafy vegetables may be due to high uptake of metals (Lato et al., 2012; Tani and Barrington, 2005). Nevertheless, the BCF values were higher for some vegetables compared to the previous studies (Jan et al., 2010b; Khan et al., 2010; Mahmood and Malik, 2014).
