Accumulation of trace elements in soil is a major concern globally due to the effects on the ecosystem and in particular, the carcinogenic and mutagenic health risks to humans. Soil samples taken randomly from two soil profiles (depths 0-15 cm and 15-30 cm) around an aluminium smelting plant (ALSCON) in Ibekwe, in Ikot Abasi Local Government Area of Akwa Ibom State, Nigeria were analysed for trace elements. X-ray fluorescence spectrometer-SPECTRO X-LAB 2000 analyser was used to determine the elements in the soil. The abundance of elements in soil followed the order: Zr>Ce>La>Zn>Y>Pb>Th>Hf>U>Sb>Mo>As>Bi in the topsoil and Zr>Ce>La>Zn>Pb>Y>Th>Hf>U>Sb>As>Mo>Bi in subsoil. Elements in soil profiles, except for Zr, Sb,Bi and U were within the earth
