Due to the importance of sewage water treatment for agricultural purpose, a series of experiments have been conducted to analyze any harmful concentration of metals/metalloids. For this purpose a pot experiment was conducted at the end of November, 2011 to analyze the effect of domestic sewage water on the accumulation of toxic metals (Lithium, Molybdenum, Cobalt, Arsenic and Selenium) in a wheat variety i.e. Millat-2011. The results were compared with the upper tolerable limit for any possible threat to human health. The pots were treated with domestic sewage water. Five control pots treated with canal water were also established for comparing the results. The results showed that the Lithium (2.66-2.68 mg/kg), Molybdenum (6.29-7.52 mg/kg), Arsenic (1.53-1.84 mg/kg) and Selenium (0.33-0.56 mg/kg) were much higher than the toxic limit suggesting severe risk of toxicity in humans consuming such wheat grains irrigated with sewage water. Only Cobalt (0.22-0.2 mg/kg) concentrations were below the toxic level. So, domestic sewage water may leads to metal toxicity in humans if used unprocessed for irrigation purpose.
