Abstract

Water shortage in agribusiness segment upheld farmers to apply city wastewater with no respect of its quality consequences for condition and important contamination of soils and plants and animals, reliant on these plants, especially with heavy metals. The principle motivation behind this examination was to investigate the amount of heavy metals in corn plant grains by means of water to soil and soil to plant and at last devouring different parts of chicken that were grown on grains of corn crop treated with sewage, channel and ground water. All samples were assayed for heavy metals. Cd, Cu, Zn, Ni, Co, Mn, Fe, K, Na and Mg were high in SW related to CW and GW. Though Co had a high concentration in sewage water but its analysis of variance of data showed that there was a non-huge distinction in its concentration in all water sources. Then again the concentration of Fe and Na were high in canal water. In sewage water irrigated soil the values in both seasons for Cd were above the safe limits however concentration of Cu, Zn, Ni, Co, Fe in all soil samples was within safe limit. Data for heavy metal concentration in plant indicated that the amount of Cd, Zn, Cu, Ni, Co were higher in the grains, shoot and root of the plants watered with SW compared to other water sources (CW, GW). As the level of Na and Fe was high in canal water so all corn plant parts that were irrigated with canal water showed the maximum concentration of these metals compared to sewage water and ground water. All groups of chicken showed a linear increase of heavy metals according to the feed they consumed. Meanwhile the enrichment factor and pollution load index for the soil and bioconcentration, bioaccumulation and transfer factor was also assessed to calculate the exchange of metals from water to soil and soil to the plant. Target Hazard Quotient (THQ) was likewise determined to evaluate the possible human wellbeing danger of heavy metals pollution from utilization of these parts of chicken (Liver, breast meat and gizzard) to the local occupants.
