Abstract

This study investigated the presence of heavy metals in periwinkle (Tympanotonus fustcata Var. Radula (L)) from the Forcados River in the Burutu Local Government Area of Delta State, Nigeria. 20g of periwinkle samples were collected from fishermen in the river, dried, crushed to powdered form and analyzed using an Atomic Absorption Spectrometric technique (AAS-Model Varian SpectrAA 220 Fast Sequential). The result showed high concentrations of heavy metals ranging from 3.5-5.0 mg/l (copper), 7.0-40.0 mg/l (zinc), and 5.6-10.0 mg/l (iron), 0.5-2.0 mg/l (cadmium), 0.5-1.0 mg/l, (chromium) and 0.3-5.0 mg/l (lead). The concentration of heavy metals result is represented in the order: chromium = lead< cadmium < zinc < iron < copper. The results show that the concentration of zinc, iron and copper are well above the FAO/WHO permissible limits. The concentrations of cadmium, chromium and lead were discovered to be below the FAO/WHO acceptable limits. This is an indication that continuous consumption of periwinkle from the Forcados river is expected to cause health issues related to heavy metals
