Gube-Ibrahim Mercy Ayinya | Ibrahim Ezekiel Gube | Gutap Satmac James "Uptake and Bioaccumulation of Selected Heavy Metals in Selected Vegetables in Bokkos L.G.A, Plateau State" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-3 | Issue-1, December 2018, pp.917-921, URL: https://www.ijtsrd.com/papers/ijtsrd19107.pdf

The concentrations of some heavy metals (Cd, Cu, Fe, Mn, Pb, Cr and Zn) were investigated in selected vegetables (Carrots, Cabbage and Spinach) and the soil on which the vegetables were grown. Sample digestion was carried out in aqua regia and the analytes were quantified using Atomic Absorption Spectrophotometer, model 210 VGP (AAS). The concentrations of these heavy metals in vegetables is as follows: Cd ranges from 0.002- 0-019 mg/kg, Cu (0.082- 0.457 mg/kg), Cr (0.033- 0.138 mg/kg), Fe (1,215- 9.837 mg/kg), Mn (0.708- 7.822 mg/kg), Pb (0.015- 0.088 mg/kg) and Zn (2.293- 4.900mg/kg). while in the soil samples, the various concentrations ranges from 0.005-0.045 mg/kg for Cd, 0.277 - 1.287 mg/kg for Cu, 0.018- 0.620 mg/kg for Cr, 19.334- 25.132 mg/kg for Fe, 1.196- 17.118 mg/kg for Mn, 0.089-0.471 mg/kg for Pb and 1.090- 5.275 mg/kg for Zn. The bioaccumulation studies show that cabbage has the highest absorption followed by carrot while the least absorption was observed in spinach. All the metals studied had concentrations within the WHO/FAO guidelines with the exception of Zn and Fe whose concentrations were slightly higher than the recommended values.
