Abstract Thesis Title: Studies on the contamination status and health risk assessment of some heavy metal ions in some selected water samples from Dkrns sector – Dakahlia governorate. Presented by: Ahmed El Sayed Hassan Mohammed Hassan El Wissif The heavy metal concentrations of Cd, Cu, Cr, Ni, Fe, Pb and Zn were investigated in drinking water in Dkrns sector, Dakahlia governorate and compared with permissible limits set by (WHO). The Cd concentrations exceed the respective permissible limits in dry seasons, while other metals concentrations were observed within their respective limits. The potential health risk that recommended by (US EPA) such as: chronic daily intake (CDI), hazard quotient (HQ) and hazard index (HI) were studied. HIs <1 therefore no health risk for the local inhabitants except in dry seasons HQ and HI >1 were observed due to Cd. |
