Abstract
The concentrations of some heavy metals (cadmium, lead, mercury and arsenic) in the soft tissues of periwinkle Tympanotonos fuscatus var. radula obtained from Eagle Island River in Port-Harcourt, Rivers State, Nigeria were studied. It was an analytical study in which an atomic absorption spectrophotometer (series 240 varian) was used to establish the concentrations of the metals. The mean concentration of metals recorded were Hg (2.10ppm), Cd (0.067ppm), Pb (2.00ppm) and As (1.26ppm). There was no significant relationship (at α0.05) between the concentrations of the heavy metals in the sampled organisms. Considering the neurotoxic effects of some heavy metals, it becomes imperative to regularly monitor heavy metal concentrations in sea foods in order to ensure the safety of such food for public consumption
