Abstract

Consumption of aquatic and non-aquatic organisms are main pathway of human exposure to Toxic elements. Health risk assessed by the total concentrations of elements in animals could be overestimated if the bioavailability or bioaccessibility is not considered. Snails are suitable tool for diagnosing regions contaminated with different heavy metals. Land and fresh water snails species were evaluated in Igbekebo, Ondo State, Nigeria. The purpose this research was to investigate level of elements present in land snails (Achatina marginata) and freshwater snails (Bulinus globosus) as well as the concentration of elements in soil. The mean concentration of soil samples for location E was higher in K, Sn, Zr and Pb than in locations A, B, C and D. The mean concentrations of Cr, Cu, Zn, Cd and Pb in both snails (A. Marginata) and fresh water snails (B. Globosus) were above the regulatory limits of the Food and Agriculture Organization (FAO). Cd had the highest enrichment values and geo accumulation values in all the locations. Nonetheless, given the bioaccumulation value of metals, a modest amount of water intake and land snails in Igbekebo is highly advised in order to prevent adverse health effects for consumers in the future.
