Abstract
Levels of some heavy metals: Iron (Fe); Copper (Cu); Cadmium (Cd); Nickel (Ni) and Lead (Pb) in some edible marine species namely: Periwinkle (Tympanotonus fuscatus); Oyster (Crasssostrea gasar); Mudskipper (Periophthalmus papilio) and grey mullet (Liza falcipinnis) were assessed during wet and dry seasons from Ekerekana and Buguma Creeks, Niger Delta, Nigeria. Generally, the following trend in decreasing order of the heavy metals in all the sea foods occurred: Fe>Cu>Cd>Ni>Pb. An overall elevated concentration of these metals was recorded during the wet season, particularly in periwinkle (T. fuscatus) from Ekerekana creek. Conversely, higher levels (P>0.05) of these metals were observed in sea foods sampled from Ekerekana creek when compared to Buguma creek, which was more pronounced during the wet season than dry season months.
