Some Aspects of the Physicochemistry and Heavy Metal Content of Water, Sediment and Cynothrissa mento (Regan, 1917) from Badagry Creek, Lagos, Nigeria

P.E. Ndimele and C.A. Kumolu-Johnson

Some physicochemical parameters and heavy metal content of water, sediment and Cynothrissa mento from Badagry Creek were studied for eight months (July, 2010-October, 2010; January, 2011-April, 2011) spanning wet and dry seasons. The heavy metals investigated are Cu, Zn, Cd, Pb, Fe and Cr while the physicochemical parameters are temperature, pH, conductivity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), salinity, turbidity, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), alkalinity and hardness. All the physicochemical parameters except temperature and dissolved oxygen exhibited significant (p<0.05) monthly variation. However, six of the physicochemical parameters (total suspended solids, turbidity, biological oxygen demand, chemical oxygen demand, alkalinity and hardness) representing 50% showed significant (p<0.05) seasonal variation. All the heavy metals studied except Cr showed significant (p<0.05) monthly variation in at least one of the environmental compartments (water column, sediment and Cynothrissa mento). The range of concentrations of the six heavy metals in Cynothrissa mento are Cu (0.06±0.02-0.91±0.19 mg kg-1), Zn (0.19±0.04-1.69±0.33 mg kg-1), Cd (0.01±0.01-0.05±0.02 mg kg-1), Pb (0.01±0.01-0.12±0.01 mg kg-1), Fe (4.33±0.43-16.88±1.32 mg kg-1) and Cr (0.01±0.01-0.05±0.02 mg kg-1). Most of the values of the physicochemical parameters and heavy metals were within the limits recommended by World Health Organisation, Nigeria’s Federal Environmental Protection Agency and United States Environmental Protection Agency except alkalinity, hardness and Fe in sediment. This study shows that the water quality variables of Badagry Creek can sustain fish and the heavy metal content is not harmful to fish and man yet.
