Metal contamination in arable soils and crops grown in and around an industrial area of Bangladesh were measured, and the transfer factor from soils to crops was calculated accordingly. The highest concentration was observed for Fe and the order of metal concentration was Fe > Zn > Cr > Pb > Cu > Ni > Cd in soils. Bioaccumulation and translocation of metals from roots to edible parts of the crop plants were varied for almost all elements studied. Absorption of metals was significantly more in the roots compared to other plant parts. Accumulation of all metals in the edible parts of the plants was compared with the recommended maximum tolerable levels proposed by the Joint FAO/WHO Expert Committee on Food Additives. Bioconcentration factors values based on dry weights were below one for all metals except Cu in the rice roots and decreased in the order of Cu > Zn > Fe > Pb > Ni > Cd > Cr. |
