چکیده:

Utilization of none-prime waters in arid regions is necessruy to supplemental water resources. The municipal EW from the Esfahan N01them Water Treatment Plant, and industrial EW from Zob-Ahan, Fold-Mobarekeh (iron foundries), Polyacril (Petrochemical Plant) and, Zohreh (dyeing plant) were selected and its effect on soil, water resources, and plant were studied. The result shows that for municipal EW the COD, BOD, TSS and, for industrial EW So42 -, cr, Hco3-, BOD, COD, N-N03, IDS, TSS, SAR and heavy metals concentrations of Cu, Mn, Cr, Co, Cd and Zn ru·ethe limiting factor and exceed the standard for agricultural land inigation. In soil in land irrigated with mlmicipal EW, the organic matter content, total nitrogen, available phosphorous and Potassium and selected heavy metals were higher than well-water liTigated lands. In soils liTigated with industrial EW the concentration of Mn, Zn, Cd and, Cu exceeded the n01mal levels, and were in critical range. The concentration of Fe, Zn, Cu and Zn in the wheat roots liTigated with EW were higher than wheat root in’igated with well-water and the wheat grain concentration of Mn and Znwhere higher than wheat grain check fields liTigated with well-water. In land liTigated with industrial EW Cu concentration was higher than nonnal and Fe concentration were higher than sufficient range. Also, Zn and Cu grain concentration increased, and Fe grain concentrations decreased compare with leaf and shoot concentration in wheat. In alfalfa, plant Cu and Zn concentration were in critical range, and Cu, Fe, and Zn concentration exceeded the sufficient range
