Abstract
The accumulation of seven heavy metals; cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), lead (pb), manganese (Mn) and zinc (Zn) in periwinkle (Tympanotonus fuscatus var radula; shell and soft tissues) and sediments collected from monthly samples along Jaja creek course was studied. Jaja creek receives effluents discharges from heavily industrialized and highly populated settlements. The sediments and periwinkles were processed and analyzed for heavy metals and the results showed that the sediments concentrated more heavy metals than the periwinkles, while the periwinkles accumulated more of these metals than the sediments. Cr was the highest concentrated heavy metals in both the normal and depurated periwinkles. The biological concentration factor (BCF) revealed that periwinkles have high potential to concentrate heavy metals in their shells and soft tissues, which is directly proportional to their sizes. However, the observed heavy metals concentrations in these aquatic organisms are below the recommended limits for human consumption. Therefore, this study advocates for environmental surveillance of the Jaja creek in order to achieve optimum sediment quality as well as contaminant-free periwinkles to safe guard human health and vitality.
