| Benzene is one of the most environmental contaminants, absorbed by inhalation, oral and dermal exposure. Forty adult male rats ( Rattus norvigicas) were divided into two equal groups: control and treated group, the treated group were housed near the source of exhaust, 2 litters of benzene were used in generator (23 Am) daily for 4 hours for 30 days, then rats were sacrificed, body weight was measured and blood samples collected for Hb, RBC, WBC, Blood Urea, Cholesterol, Creatinine, Protein and Albumin assessment as well as histological study for liver and kidneys. The results showed decrease in body weight. Hb, RBC, WBC and blood urea were significantly increased, whereas serum cholesterol, creatinine, protein and albumin concentrations showed slight increase as compare to treated group, as well as congestion in liver and kidney. In conclusion, the present study demonstrated that benzene emission exhaust resulted in sever change to the liver, nephropathy and blood picture |
