ABSTRACT
Fishes obtained from Iyede-Ame
River were investigated for trace elements concentrations using atomic
absorption spectrophotometry of model PYE UNICAM SP 2900. The trace
metals analysed were arsenic, barium, cadmium, chromium, lead and
selenium. The result obtained revealed that all the aforementioned
trace elements detected and their concentrations varied significant (P<
0.05). Trace elements such as barium, cadmium, lead and selenium were
found to have elevated concentrations when compared with the
W.H.O. fresh water standard for fishing. On the other hand, arsenic and
chromium concentrations were within the above set standard. Trace
elements concentrations in this study were compared with other similar
research carried out by scientists. These fishes studied are good
indicators for pollution monitoring in Nigerian rivers.
