Abstract

The heavy metals studied in this work were cadmium, lead, mercury and arsenic. The concentrations of the heavy metals in the soft tissues of periwinkle Tympanotonos fuscatus var. radula obtained from Brass Island of Bayelsa State Nigeria were analyzed in the laboratory .The soft tissue of the mollusk was carefully extracted, homogenized and prepared for analysis using atomic absorption spectrophotometer ( series 240 varian).The mean concentration of metals recorded were: Hg(2.02ppm), Cd (0.042ppm), Pb(0.360ppm) and As (1.54ppm). There was no significant relationship(at α0.05 between the concentrations of the heavy metals in the sampled organisms. Considering the public health implications of heavy metal contamination, it becomes imperative to assess the heavy metal concentrations in sea foods regularly.
