Abstract: 

High lead level in blood is said to have adverse effects on human health. This study was conducted to determine blood lead, liver enzymes, triglycerides and total cholesterol levels in traffic policemen and petrol station workers. A total of 150 subjects were randomly selected from different cities of Sudan, in which 100 samples taken as exposed group and 50 as un-exposed (control). Blood lead concentration was determined by using atomic absorption spectrometer. Biochemical parameters were measured in serum using standard methods. Mean blood lead concentration in exposed group was found to be 32.2 µg /dl, whereas in control was 12.4 µg/dl. Result showed that serum aspartate transaminase (AST), gamma glutamyltransferase (GGT), alanine transaminase (ALT), total cholesterol (TC) and triglycerides (TG) were significantly higher in samples compared to control, while alkaline phosphatase (ALP) was significantly decreased in exposed group compared to control. Result indicated that long-term exposure to air lead pollution affects liver functions and deteriorates human health.
