Comparative Study on The Determination of Some Major, Minor-Essential and Toxic Metals From Two Species of Cactus Fruit (Opuntia Ficus Indica and Opuntia Stricta) and Their Supporting Soil Samples Cultivated in Two Zones of Tigray, Northern Ethiopia
Journal Title: International Journal of Food Science, Nutrition and Dietetics (IJFS) - Year 2016, Vol 5, Issue 5
Abstract
A comparative study was carried out for the determination of some selected metals (K, Mg, Ca, Cu, Zn, Ni, Mn, Cd and Pb) in fruits of two cactus species (Opuntia ficus indica and Opuntia stricta) and supporting soil from two zones of Tigray regionof northern Ethiopia. After digestion with microwave acid digestion, some selected metals were determined by Flame Atomic Absorption Spectrophotometer. The concentration of metals obtained for these fruits are found to be within the range of WHO and other international guideline limits. Levels of the metals concentration in this study is that, in all the fruit samples, K >Ca > Mg in concentration and the levels of trace metals are, Zn > Mn > Cu > Ni. Concentrations of Cd and Pb are below the method detection limit in all the fruit samples.
