The concentration and contamination levels of some heavy metals in Fadama soils utilized for agricultural activities within the vicinity of dumpsites in Lokoja were assessed and presented. The reconnaissance was conducted, and soil samples were collected from four different locations to test the type of soil and heavy metal content. Simple random sampling technique was adopted for plot selections, soil samples were analyzed with atomic absorption spectrophotometry. The value of the Zn content ranged between 37.10mg/kg at Banda and 50.96mg/kg at Kabawa, Mn ranged between 212.92mg/kg at Nataco and 452.14mg/kg at Kabawa. Iron ranged between 1071.80mg/kg at Banda and 1913.40mg/kg at Nataco. Cu and Pb level vary little amongst the different plots, from 3.56mg/kg at Ganaja to 6.84mg/kg at Nataco and 1.80mg/kg at Banda to 3.38mg/kg at Nataco. The heavy metals did not show significant correlation with the particle size fractions and organic matter of the soil. The heavy metals of respective plots were very low compared to European Union maximum permissible level; suggesting that the level of metals in this study are not threatening for now, but there is need for continuous monitoring to checkmate future trend for agricultural sustainability.
