Abstract: The toxicity and PAH of
C. gariepinus (0.9±0.01g) to 1, 3, 6, 9, 12 and 0.0 ml/L of crude oil and diesel was determined. There was no mortality in the control but 10, 20, 50 and 60% occurred in crude oil and 10, 20, 30, 40 and 60% in diesel after 96 h exposure. The logarithmic probit lines and R
2: y = 1.372x + 3.724, R² = 0.997 and y = 1.665x + 3.694, R² = 0.998 and 96-h LC
50: 9.6 and 11.0 ml/L represented toxicity values for crude oil and diesel. Total PAH in exposed fish ranged from the highest value of 99.68±4.81 crude oil > 97.30± 14.57 diesel oil ng/µL the lowest value of 0.061 Nap to the highest value of 384.68 in DahA for crude oil and Diesel oil indicated lowest value of 2.22 Ace to highest value of 389.05 ng/µL DahA. Mean ∑ 16PAH of lighter product showed greater toxicity than heavier products require further investigation to the pharmacokinetics of the products on fishes.
