Abstract:

Many trace elements are essential to human being but in some cases there is only a small safety range requirement to avoid toxicity. In this study, traces of some minerals in samples of water, fish, and ponds sediments at Ado, Ikere and Iyin Ekiti, Ekiti State, Nigeria were determined. Atomic Absorption Spectrophotometer was used for the determination of Cadmium, Copper, Cobalt, Iron and Manganese. Complexometric titration was used to determine Magnesium and Sodium while Calcium and Potassium were determined by flame photometer. Results of these determinations show that Cadmium was not detected at all in all the water and sediment samples of the three ponds, it was not detected in Ado and Ikere water and sediment samples. Cobalt was detected in both water and sediment samples from Iyin and Ado Ekiti fish ponds. It was observed that even though Phosphorus and Magnesium were not detected in all the water samples, the concentration ranges from 0.87 ± .09 to 41.67 for Phosphorus and 72.94 to 867.13 mg/L for magnesium in both fish and sediment samples. Generally, it was observed that the concentration of these metals ranges from 2116.67 ± 62.36 for Calcium to 0.004 ± .001 for Copper. The concentration trends of these minerals shows highest concentration in fish, followed by sediment and least in water thus confirming the presence of trace metals in the selected fish, water and pond sediments.
