Detection the Contents of Minerals of (Sodium, Potassium and Calcium) and Some Metals of (Iron, Nickel and Copper) in some vegetable and soil samples collected from Al-Marj Region, Libya

The contents of minerals of Sodium, Potassium and Calcium) and some metals of (Iron, Nickel and Copper) in some vegetable samples collected from Al-Marj Region, Libya, were measured, the contents of minerals were determined by Flam photometer. On the other hand, the contents of heavy metals were estimated by rapid, sensitive and accurate method by Spectrophotometer, the results recorded that: the contents of minerals were fluctuated in the ranges of the results showed that the concentrations of Na of soil samples were ranged between (11-24),while the concentrations of Ca were ranged between (4-11) ppm and the concentrations of K were ranged between (18-27) ppm. For the vegetable samples, the results showed that the concentrations of sodium, calcium and potassium were ranged as following: (13-54), (4-17) and (27-69) ppm, respectively, the contents of heavy metals in soils which selected in this study were fluctuated in the following ranges: (0.012-0.033), (0.560-1.207) and (0.057-0.219) ppm. For the metals of (Copper, Iron and Nickel), respectively. While in the vegetable samples were ranged as following: (0.002-0.037), (0.007-0.060) and (0.009-0.027) ppm for (copper, iron, and Nickel), respectively, the concentrations of copper (Cu) iron (Fe), Nickel (Ni) and Nitrogen (N) of the studied samples (µg/g).
