“…Investigation (Okoye et al, 2002) has revealed that aquatic organism in River Niger has nickel concentration of mean value 1.23 ppm higher than the value obtained from Aba river. High concentration of Ni in fish poses health hazard to human beings who eat fish.…”

“…Nwaedozie (1998) working on Kaduna river reported Zn concentration of mean value 6.60 ppm in fresh catfish. Okoye et al (2002) working on the River Niger reported Zn concentration of mean value 2.32 ppm in aquatic organisms. The Zn level obtained from River Niger is lower than the values obtained from Aba and Kaduna rivers, this may be due to fewer industries that discharge waste into the River Niger.…”

“…It has been reported (Oladimeji, 1986) that Kaduna river in Nigeria is contaminated with heavy metals namely: Cu, Cr, Fe, Mo, Ni, Zn, Cd, Hg, V and Pd because local textiles, brewery and refineries discharge their untreated waste products into the river. These elemental contaminants may either be ingested directly through drinking water by man, or through the food chain by eating fresh vegetables or other aquatic animals obtained from the river.…”

The elemental contaminants in water and fish samples from Aba river were studied. The elements studied were Zn, Ni, As, Hg, Co and Mn. Three water samples and three samples of different fish species were collected from different locations in the river. The water and fish samples were analysed for elemental contaminants using Atomic Absorption Spectrophotometer (AAS). The elemental toxicants Zn and Mn were identified in appreciable amounts in fresh fish species namely, Lates niloticus and Oriochronis niloticus, of mean values 8.012 ppm and 0.861 ppm, respectively. The analysis also shows arsenic concentration of mean value 0.01 ppm in Lates niloticus. The analysis of frozen fish samples purchased from the Waterside market located near the river shows Ni and Hg levels of mean values 0.83 ppm and 0.02 ppm, respectively. The levels of elemental contaminants As, Zn, Hg and Mn from the water samples have mean values 0.082 ppm, 11.284 ppm, 0.201 ppm and 1.024 ppm, respectively. There are five industries that discharge waste products into Aba river. In view of this, there is a need to determine the level of pollution of the river, since the inhabitants depend on the river for their drinking water, fishing and other domestic uses. This study is aimed at determining the level of heavy metal toxicants in fish and water samples from the river. The effect of these elemental contaminants and the associated health hazards were examined.
