The fishes were of variable sizes while the organs investigated in them were head, intestine, gills and flesh. The lead, magnesium, zinc, chromium, iron, manganese and copper values were lower in fish organs than in the water and soil, thereby showing a low level of bioconcentration. The trace metals determined were below the deleterious level however there is a need for further monitoring.
