title: Lead exposure among nursery children in Chorzów.
abstract: The main goal of this study was to determine the level of exposure to lead of selected representatives of the child population attending nursery school, aged 2 to 4 years, residing in three districts of Chorzów with different traffic intensities. The numbers of tested samples of children were 41, 43, 40. The tests were made in summer. Lead (Pb-B), zinc protoporphyrin level (ZPP), hemoglobin (Hb), erythrocyte count in blood (E), and delta-aminolevulinic acid (ALA) and creatinine concentration in urine were determined. The highest Pb-B level observed was 300 micrograms/l; the geometric means of the blood lead concentrations were 131, 132 and 119 micrograms/l and were not statistically different. Median ranges were 118, 133 and 114 micrograms/l. Ranges above the 200 micrograms/l level were found in 19.5%, 11.8% and 15% of the children. The obtained data suggest higher lead absorption in the examined child population.
