The levels of five metals, Fe, Cu, Zn, Cr and Pb in Macrobrachium vollenhovenii from Epe Lagoon
were investigated from March, 2008 to December, 2008. The monthly concentrations of the metals varied
significantly (p<0.05) but seasonal dynamics (dry and rainy) had no effect on the concentrations of these metals
except Zn. The values of these metals recorded in this study are below the values reported in previous studies
carried out in industrialised parts of Nigeria. They are also lower than the recommended limits set by Food and
Agriculture Organisation and World Health Organisation. This study suggests that the Macrobrachium vollenhovenii from Epe Lagoon contains the heavy metals studied but their levels in this shell fish is still within acceptable limits.
Key words: Bio-indicator, Epe Lagoon, heavy metals, Macrobrachium vollenhovenii, physico-chemistry, ,
