Environmental contamination of PCBs may occur from the disposal of old electrical equipment containing PCBs. Their characteristic low solubility contributes to their ability to bioconcentrate which leads to bioaccumulation. This study evaluates mechanism underlying toxic damage to the liver induced by PCBs extracted from soil of three dumpsites. Oral administration of extracted PCBs and co-administration with vitamin C after two weeks the liver of each rat was isolated and homogenized for toxicological studies. It was found that administration of PCBs significantly (p<0.05) reduced activity of AST relative to Control, co-administration of vitamin C with PCBs significantly increased (p<0.05) liver AST compared with PCBs only but was still significantly lower (p<0.05) relative to Control. Groups 3 and 5 MDA is about 2 ½ and 2 folds respectively that of Control. GSH concentration of liver of rats in Groups 3-8 was significantly lower (p<0.05) relative to the Control. The present study has shown that PCBs induce toxic stress on the liver as evidenced by enzymes activities. Although the mechanism whereby PCBs induce toxic stress on the liver is not fully elucidated in this study, we have however shown that PCBs interferes with protein and carbohydrate metabolisms in the liver by loss of ALT and AST activity.
