Distribution and concentration of some mineral elements in soil sediment, ambient water and the body parts of Clarias gariepinus and Tilapia quineensis fishes in river Tammah, Nasarawa state, Nigeria

An investigation into the concentrations and distributions of lead, magnesium, zinc, chromium, iron, manganese and copper in the soil sediment, river water and the organs of Clarias gariepinus and Tilapia quineensis was undertaken with a view to evaluating the interplay of these inorganic minerals in the various matrices. The fishes were of variable sizes while the organs investigated in them were head, intestine, gills and flesh. The lead, magnesium, zinc, chromium, iron, manganese and copper values were lower in fish organs than in the water and soil, thereby showing a low level of bioconcentration. The trace metals determined were below the deleterious level however there is a need for further monitoring.
