Estimating of Pollution by Elements of Cadmium and Lead in Water Wells in Some Areas of Al-Ajailat City

Abstract

This study aimed to estimate drinking water contamination with the elements of cadmium and lead in water wells in some areas of Al-Ajailat city, where 100 samples were collected at a rate of 10 wells in ten areas of Al-Ajailat city, which were: Al-Ghulmiah, Ghout Al-Dis, Al-Duraniyah, Jnan Atiya, Saniyet Khumilaj, Al-Afran, Al-Hamam  Alsiyahe, Al Zarmagah, ,Al Wali Abu Ajila and downtown areas. The results of the analysis in which the spectral absorption device (Atomic Absorption) was used in the laboratories of the Department of Environmental Engineering, Faculty of Engineering, University of Sabratha, showed that the water samples from all walls under study areas were free of cadmium. The results also showed that the lead element concentration in the areas under study was an average of: 0.12, 0.12, 0.15, 0.17, 0.13, 0.20, 0.30, 0.29, 0.33 and 0.35 ppb depending on the regions respectively. The results showed that using the statistical analysis (ANOVA one way) at a significant level (P ≤0.05), that the highest concentrations were found in the wells of the Al Wali Abu Ajila and downtown areas (Alsuwg(. As shown through the results obtained They should concentrate the elements of cadmium and lead within the permissible limits according to the Libyan standard specification L.S.S 10 for drinking water issued by the National Center for Standardization and Standards for the year (2016). Also, according to the WHO drinking water quality specification  (WHO, 2004).
