摘要

The heavy metal concentration in the fish Channa obscura from Alaro Stream in Ibadan was assessed. Twenty-seven fish (C.obscura) were collected between January and December 2003 (Dry and rainy season).Muscle, liver, bone, gills, gut and fins of the fish were analyzed for cadmium (Cd) and lead (Pb) using the inductively coupled plasma-mass spectrometer (ICP-MS).Quality assurance of the results was obtained through the use of bovine liver as a standard reference material (SRM) from the National Institute of Standards and Technology (NIST). The range of the Cd in the organs of C. obscura was 0.000- 0.507ppm, with the highest mean concentration in the gut (0.500ppm) and the lowest in the bones (0.057ppm). The order of mean increment in the Cd concentration was: bone
