Zafar Iqbal Khan
Abstract
Current study was conducted in Sahiwal, Sargodha, Pakistan. To find out the effects of heavy metals (Cadmium, Nickel, Iron, Manganese, Copper, Chromium, Zinc and Cobalt) on wheat variety (AARI-2011) irrigated with diverse treatments of domestic waste water. Heavy metal concentration in soil and grains was considerably affected by sewage water. Positive and significant correlations of heavy metal transfer from soil to grains were shown by all metals. Current results showed that the concentration of cadmium was high in grains of wheat variety (AARI-2011). Bio concentration factor and enrichment factor for Mn was highest among all metals. Values of Daily intake of metal, Pollution load index and health risk index were high for cadmium. Concentration of cadmium in grains was above permissible level and was not safe for human health. It was concluded that the wheat and vegetables irrigated with untreated waste water may cause heavy metal toxicity in humans. So, Sewage water should be treated carefully before its application to plants.
