ASSESSMENT OF HEAVY METAL CONCENTRATIONS IN FADAMA SOILS UTILIZED FOR AGRICULTURAL ACTIVITIES WITHIN THE VICINITY OF DUMPSITES IN LOKOJA, NIGERIA

Abstract

This study aimed to assess the concentration and contamination levels of heavy metals in Fadama soils utilized for agricultural activities within the vicinity of dumpsites in Lokoja, Nigeria. Soil samples were collected from four different locations and analyzed using atomic absorption spectrophotometry. The results showed that the levels of Zn, Mn, Iron, Cu, and Pb in the soil varied among the different locations, but were generally lower than the European Union's maximum permissible levels. There was no significant correlation between the heavy metal content and the particle size fractions and organic matter of the soil. While the levels of heavy metals in this study may not be threatening for now, continuous monitoring is necessary for agricultural sustainability in the future. This study highlights the need for further research on heavy metal contamination in Fadama soils in Nigeria, especially in areas close to dumpsites.
