Determination of Heavy Metals in Fish Tissues, Water and Sediment from the Onitsha Segment of the River Niger Anambra State Nigeria


Izuchukwu Ujah I, Okeke DO and Okpashi VE

The gills, flesh, intestines and skins of fish from Onitsha segment of River were carefully, dissected from the fish samples. Water and sediment samples were equally collected from two sites for heavy metal determination using Atomic Absorption Spectrophotometer (AAS 220 FS). The highest concentration detectable was in the sediment sample followed by the concentrations in the fish samples. Iron concentration detected was highest followed by lead with antimony and cadmium mostly undetectable. Variations in the parameters determined were found to be statistically significant at p<0.05.
