Abstract:

An experimental study was performed to investigate the effect of urban waste water on heavy metals (lithium, molybdenum, cobalt, arsenic and selenium) accumulation in a wheat variety, Lasani-2008. Seeds of wheat were implanted at the end of November, 2011and irrigated with waste water. In order to compare the results, a series of control pots were established. The results showed that the values of various metals in Triticum aestivum L. grown up in sewage water were higher than in the control water treatment. It is therefore necessary to process the sewage water before irrigation to prevent heavy metal toxicity in humans. The results also showed that the concentrations of molybdenum (7.5-7.62 mg kg-1), arsenic (1.53-1.7 mg kg-1) and selenium (0.33?0.56 mg kg-1) were found much higher than the toxic limit suggested for humans. Only the concentration of cobalt (0.16?0.25 mg kg-1) was found below the recommended toxic level. Therefore, the sewage water should be processed before irrigation to prevent from toxicity due to heavy metal.
