Abstract

Due to several reports of pollution in Ogoni land, this study was carried out to determine how safe these fish species are for human consumption. The amounts of lead, arsenic and cadmium in the flesh of Tilapia guineensis and Sarotherondon melanotheron found in Bodo River were studied using X-ray fluorescence (XRF). The amount of lead found in the two fish species ranged between 3.2-5mg/kg, arsenic 1.8-2.1mg/kg and cadmium 0.6-2mg/kg and were higher than tolerable limits recommended by health agencies. The amounts of these elements show that these fish species from this location are unsafe for human consumption.
