Abstract

The relationship between concentrations of heavy metals in dominant aquatic fresh water swamp organisms (snails and prawns), Otuoke Bayelsa state Nigeria was investigated. The samples collected from similar locations within the study area were analyzed for the present of nickel, cobalt, lead, chromium and cadmium. The results obtained indicated that mean concentrations of nickel, cobalt, lead, chromium and cadmium in snail were 1.88, 0.44, 1.42, 0.728 and 0.008 mg/g while the corresponding mean concentrations in prawn were 1.96, 0.44, 1.12, 0.719 and 0.008 mg/g. Strong correlation (R2 = 0.9624) was obtained for the concentration of these heavy metals in snails and prawns which indicates that these organisms have common sources of heavy metals. However, concentrations of the study heavy metals in prawn and snail were within the permissible tolerance limit
