Blood lead and serum zinc concentrations of school children were determined in Bursa and in a small village nearby. The geometric means of Pb were 4.78 mug/dL, both for the village and city center. Geometric means of zinc were 78.8 mug/dL, and 71.6 mug/dL for the village and city center, respectively. About 8% of the total population had blood lead levels higher than 10 mug/dL, and 28% a serum zinc concentration less than 70 mug/dL, which is below reference concentration. Bivariate analysis indicated a relation between blood Pb, sex of the children and time spent outdoors.
