Evaluation of human risks of surface and groundwater contaminated with
Cd and Pb south of El-Minya Governorate, Egypt
Abstract. Water pollution with Cd and Pb has worldwide concern because of their health impact. Evaluation of their concentrations and potential human health risks of surface and groundwater south El-Minya Governorate, Egypt is the main aim of the study. Fifty-five samples were collected; 30 samples surface water and 25 samples groundwater. The samples were analyzed using Atomic Absorption Spectrometry (AAS) to determine Cd and Pb contents. The heavy metals levels in both of surface and groundwater exceeded the maximum allowable level for drinking water which set by WHO. The hazard quotient and hazard index showed that groundwater may pose a health risk to residents, especially the children, primarily due to the high Cd content. In addition, there might be some concern for adverse Carcinogenic health effects. The pollution returns to human activities. The water can be recommended for irrigation not for drinking.
