This study assessed the levels of heavy metals(lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni) and arsenic (As), manganese (Mn), copper (Cu), iron (Fe), and zinc (Zn)) present in water leaf (Talinum triangulare) from a dumpsite(DS) in Cassidy and a farmland (FL) in Ojo, Lagos, Nigeria between August-November, 2019. Samples of waterleaf and soil obtained from DS and FL were digested and analysed using standard method. Only Fe and Zn in the leaf and stem had significant (p<0.05) different between the DS and FL. The values are (93.68±1.19mg/kg, 62.51±83.56mg/kg) for the leaf and (54.26±2.56mg/kg, 49.38±1.87mg/kg) for the stem. Also, Fe in the root of T. triangulare grown on DS were higher (p<0.05) than that grown on farmland. The concentration of contamination factor (CF) and enrichment factor for both DS and FL indicated low degree of contamination. Though, the metals were still within the WHO permissible limits, high contamination of T. triangulare with Fe and Zn could pose health problem for consumer. However, T. triangulare in this study especially from the farmland could be recommended for people with deficiency in Fe and Zn.
