UNLABELLED: The role of lead (Pb) as an environmental cause of nephropathy is difficult to ascertain due to the difficulty to determine clinically its exposure. AIM: To assess lead levels and renal function in a group of males working in mechanical workshops. MATERIAL AND METHODS: Blood and urine samples were obtained from 100 mechanical workshop workers aged 38 ± 16 years and 95 non-exposed office clerks aged 37 ± 17 years. Blood lead and creatinine levels were determined. In exposed workers, urinary excretion of intestinal alkaline phosphatases (IAP) and N-acetyl-glucosaminidase (NAG) were measured as early markers of renal failure. RESULTS: Blood lead levels were 66.4 ± 43 and 33.6 ± 18 µg/L among mechanical workshop workers and non-exposed controls, respectively, p < 0.01. The figures for serum creatinine were 0.9 ± 0.1 and 0.9 ± 0.1 respectively, p = NS. Among exposed workers urinary excretion of IAP was 0.47 ± 0.6 U/L and of NAG, 0.92 ± 1.1 U/L. There was a positive correlation between blood lead levels and NAG excretion (r = 0.284) and IAP excretion (r = 0.346). CONCLUSIONS: Exposed workers had higher blood lead levels and there was a weak positive association between these levels and the urinary excretion of NAG and IAP.
