The main objective of this study was to assess the metals level in Aloe Vera and in the soil where the Aloe Vera plant has grown in three sites, namely; Konso, Welaita and Arba Minch in southern region of Ethiopia using flame atomic absorption spectrometry (FAAS). The results of this study reveal that Aloe Vera plant has the ability to accumulate relatively higher amounts of K and Mn among the determined macro-and micro-elements, respectively. The mean levels of metal in Aloe Vera among three geographical areas in this study could be put in the following order: K (51.880 mg/Kg>> Ca (27.440 mg/Kg) > Mg (7.890 mg/Kg) > Na (2.335 mg/Kg) > Mn (2.083 mg/Kg) > Fe (2.043 mg/Kg) > Ni (2.033 mg/Kg) > Cr (1.670 mg/Kg) > Co (0.947 mg/Kg) > Cu (0.189 mg/Kg). But the metals level in soil are decreased in the order of: Ca (25.110 mg/Kg) > Mg (7.600 mg/Kg) > K (2.764 mg/Kg) > Na (2.330 mg/Kg) > Ni (2.240 mg/Kg) > Fe (2.157 mg/Kg) > Cr (1.700 mg/Kg) > Co (1.650 mg/Kg) > Mn (1.510 mg/Kg) > Cu (0.189 mg/Kg). Hence, the metal level in Aloe Vera are more dominant since plants absorb metal ions from different sources and then hyper-accumulated.
