In this study, the concentrations of Lead (Pb) in periwinkles (Tympanotonosfuscatus) and river sediments and were determined from 25 sampling stations in Eagle Island River in Port Harcourt Rivers State, Nigeria, using Atomic Absorption Spectrophotometer (AAS). The mean ±SD concentrations of Pb in periwinkles and sediments are 0.91±0.54 mg/Kg and 0.22±0.19 mg/Kg respectively. The mean concentrations of the heavy metal Pb is higher in periwinkle than in sediment (p<0.05). The results obtained from this analysis in periwinkle also showed that it exceeded the tolerable values in fish (aquatic organism). The correlation coefficient between Pb in sediment and that in periwinkle is 61.5%. The result of this study shows that sea foods obtained from this river is a potential source heavy metal poisoning. This calls for adequate legislation to protect the water bodies from heavy metal poisoning.
