Abstract

The present study was carried out to evaluate the accumulation and translocation of heavy metals in soil and in paddy crops that have been irrigated with recycled and non-recycled water, and to investigate the absorption of heavy metals in crops. In this study, the amounts of heavy metals (Cd, Cr, Cu, Pb, Zn, Mn, and Fe) present in various parts of rice plants were ascertained. The results indicated that the average concentrations of heavy metals, except for Cd,were higher in the soil irrigated with recycled water than in the soil irrigated with non-recycled water. Meanwhile, in various parts of the rice plant (roots, stem, leaves, straw, and grains) the concentrations of heavy metals, except for Cu and Mn, were higher in those plants that had been irrigated with recycled water compared to those that had been irrigated with non-recycled. The highest concentration of heavy metals in this study was in the roots ratherthan in the parts of the rice plant that were above the ground (stem, leaves, straw and grains), except for Mn, which was present in significant amounts in the leaves.The bioaccumulation factor was higher for Cd compared to other metals in the area irrigated with recycled water, whereas it was higher for Cu than for other metals in the area irrigated with non-recycled water. The order for the transfer factors from the soil to the rootsfor the metals in the areas irrigated with recycled water and nonrecycled water were Cd > Cu> Zn> Pb> Mn> Fe> Cr and Cu> Mn> Cd> Zn> Pb> Fe> Cr, respectively; from theroots to the straw the order was Mn> Cd> Zn> Cu> Cr> Pb> Fe for the area irrigated with recycled water, and in the order of Mn> Zn> Cd> Cr> Cu> Pb> Fe for the area irrigated with non-recycled water; fromthe straw to the grains the order was Zn> Pb> Cu> Cr> Cd> Fe> Mn and Cd> Cu> Fe> Pb> Zn> Cr> Mn in the areas irrigated with recycled water and non-recycled water, respectively. However, these concentrations of heavy metals in the soil and rice grains were still below the maximum levels specified in the guidelines of the Codex Alimentarius Commission and the World Health Organization.
