Anthracene, composed of three-ringed polycyclic aromatic hydrocarbon, is a widely known hazardous ubiquitous environmental pollutant. Anthracene is used to make dyes, plastics, and pesticides. The study aimed to estimate the effects of anthracene on liver and kidney functions of common carp. Ninety fishes were adapted and acclimated to the laboratory conditions for one week before starting the experiment, then they were exposed to (7.5mg/L, 10mg/L, 12.5mg/L) of anthracene for 72 hours. Results demonstrated that the LD₅₀ of anthracene in fish was (10 mg/L) according to the LC₅₀ values. Fish were then exposed to three sub-lethal concentrations of the anthracene (2.5 mg/L, 5 mg/L and 7.5 mg/L) and a control with 0.00 mg/L. Afterwards (72 hours, 10 days, 20 days) fishes were sacrificed to take the kidney and liver to estimate the organs' function. The liver enzymes (AST, ALT and ALP) assessed were higher than the control group values. The higher recorded average of ALT was 26.87 (U/L) after exposure to anthracene (7.5mg/L), while the lowest average of ALT in the control group was 4.64 (U/L). Moreover, the lowest average of AST was 4.09 (U/L) in the control group, whereas the highest average was 27.58 (U/L) after exposure to anthracene (7.5mg/L). For ALP, the lowest average was 4.54 (U/L) in the control group while the highest was 18.52 (U/L) after exposure to anthracene (7.5mg/L). In addition, creatinine and urea levels in kidney tissue showed a significant increase when compared to the control group. The highest average of creatinine recorded was 0.83 mg/dL in the group treated with 7.5 mg/L and the lowest average was 0.14mg/dl in the control group. On the other hand, the highest average of urea recorded was 21.48 mg/dl in the group treated with 7.5 mg/L, while the lowest average was 8.66 mg/dl in the control group. This study concluded that the anthracene has a toxic effect on the liver and kidney of the common carp.
