| Abstract | ||
| Countries with high population density such as Iraq, are facing many health problems caused by pollution resulting from population activities on the different components of the environment burden which is the most dangerous of these pollutants are heavy metals in the waters of rivers, and that most of the water treatment plants where there is no chemical treatment to remove heavy elements stage. This project aims to find out the concentration of toxic heavy metals and cancer-causing disease in humans in the case of non-processed. Where the study of concentration of heavy metals in the three water treatment plants in Diwaniya city first in the north of the province of Diwaniya (Diwaniya large project, "Project No. 6") and in the center (water treatment plant in Aljazaer) and the South of Diwaniya city (water treatment plant in Aleskan). The aim of the selection of three sites to demonstrate the impact of the discharge of sewage from the city on the sites of three drinking water treatment plants. Heavy elements that have been studied in this research are (nickel, cadmium, aluminum, mercury and lead) for three drinking water treatment plants, and for five stages which were (the intake (the river), sedimentation, after filtration, the ground reservoir, and the water network). These stages were identified to indicate the effect of the treatment stages on the concentration of these elements in terms of increase or decrease. The results of the study showed high concentrations of both the aluminum and lead which were above the permissible limits of the standard Iraqi standard, where concentrations of the lead were high for all stages of treatment. The results of the study showed that the concentration of the aluminum is more than the permissible limits in all stages of drinking water treatment due to adding alum to the rapid mixing tank. Concentrations of the remaining heavy metals (nickel, cadmium and mercury) were few or nil and were within the limits of Iraqi standards. | ||
