Concentration of Heavy Metals in Soil and Staple Crops and the Associated Health Risk
Journal Title: Archives of Hygiene Sciences - Year 2017, Vol 6, Issue 4
Abstract
Background & Aims of the Study: The main objectives of the current research were (1) to study the extent of soil pollution by heavy metals (Ag, Cd, Cr, Cu, Mn, Ni, Pb, Zn, Ba and Li) in sampling locations (2) to investigate the extent of heavy metal pollution and soil to plant transfer of these elements in wheat and barley (3) to study the health risk of heavy metals via consumption of wheat grains for adults and children. Materials &Methods: The levels of heavy metals in 29 sampling locations in soil and different parts of wheat and grains of barley were quantified in Shahrood and Damghan of Iran by inductively coupled plasma (ICP) optical emission spectroscopy (ICP-OES). Different statistical methods including ANOVA were used for the comparison of heavy metals in different soil groups and plant's tissues. Results: All of the bio concentration factors (BFs) were lower than one indicating the low level of accumulation in wheat and barley. The BFs were higher in aerial parts than that of grains showing the restricted translocation of these elements by wheat and barley. The highest accumulation was obtained for Zn, Ag and Cu. Conclusions: Considering Hazard Quotients (HQs), there was not any detrimental effect due to the consumption of wheat grains in the study area. The HQs of all heavy metals for adults were higher than that of children. The highest and lowest HQs values were for Mn and Cr in both age groups, respectively. The Hazard Index (HI) associated with wheat grains for children and adults were 1.36 and 2.06, respectively which is indicated the adverse health effects due to the consumption of this staple crop.
