دراسة مستوى عناصر الخارصين، الزرنيخ، الكادميوم والرصاص في عينات من أوراق الزيتون بالقرب من مصنع أسمنت المرقب- ليبيا

This study was conducted to measure the level of Zinc, Arsenic, Cadmium and Lead in olive leaves near Elmergib Cement Factory. The samples were collected from different distances (250, 500, 750, 1000m) far away from the factory, in November 2013 and January 2014. The analysis was carried out using Atomic Absorption Spectrophotometer. The obtained results showed that, the average concentrations of the metals in the samples collected in November 2013 were: 988 mg/Kg for Zn, 8.70 mg/Kg for As, 0.400 mg/Kg for Cd and 11.4 mg/Kg for Pb. For the January 2014 samples, the average concentrations for Zn, As, Cd and Pb were: 1123, 13.20, 0.4000 and 11.30 mg/Kg, respectively. It is also found that, the zinc had the highest concentration in all subject samples, and its concentration was exceeded the natural limits of the element in the plants. Although, the rest of the elements were found with relatively low concentrations. The results also revealed a strong correlation between concentrations of zinc with the concentrations of   arsenic, lead, and cadmium
