Soil contaminated with heavy metals poses an ecological risk especially to public health. The aim of this work is to assess the ecological risk of heavy metals in soil of Lagos State University (LASU), Epe, Lagos State, Nigeria. Soil samples were collected from 8 different points in LASU which were stored in various polythene bags labeled SS1 – SS8. A control sample was taken 1 km away from LASU and was labeled SC9. All the sampling locations were identified using handheld Global Positioning System (GPS) for the purpose of universal identification. The soil samples were analysed for nickel (Ni), lead (Pb), copper (Cu), Zinc (Zn), chromium (Cr), cadmium (Cd) and Iron (Fe) using Atomic Absorption Spectrophotometer. Enrichment factor (EF), potential ecological risk (Ei) and ecological risk index (RI) were carried out using the data from the analysis. The results revealed that all the EF values were less than 2 except that of lead in SS1. The Ei values were less than 40 except that of lead in SS1. Moreover RI values of all the soil samples investigated were less than 150. It was obvious from this work that the soil of LASU, Epe, Lagos State, were not enriched with heavy metals and have a low potential ecological risk.
