Abstract

Heavy metals accumulated in plants influence human health. The objectives of the present study are to estimating heavy metals contamination in soil and rice plant (Oryza saghdtiva L.), in agricultural lands of Al-Mishkhab area and assessment the health risk for heavy metals in soil and plants. Transfer factors (TF) of heavy metals from soil to variuos parts of paddy plant and its health risk were detected. Concentrations of toxic heavy metals (Cd, Cr, As, and Pb) and the micronutrients (Cu,Mn Mo,  Se and Zn) were detected in  the paddy field soil and plant parts by Inductively coupled plasma – Mass spectrometry (ICP-MS) technique. Results displayed that Mn and Cd are found to be accumulated more in stem than in root. The concentrations of heavy metals were found to be within allowable worldwide limits for ordinary soils, except As, Cr, Mn and Ni which were higher than the amount of uncontaminated soil. whereas heavy metals in cultivated soil are higher than those in close uncultivated land soil expect; As, Cr and Mo. Transfer of Mn and Zn from roots to stem and from stem to grain were higher as their concentrations were higher in stem than that of roots and grains. Health Index (HIs) rates for seven metals (As,Cd,Cr,Cu,Ni,Pb,Zn) of rice consuming were 1.7627 for adults and 0.9159 for children propose their adverse health effects in the near futurity.
