title: [Exposure to lead in selected population groups. IV. Lead exposure among nursery children in Chorzow].
abstract: Main goal of this studies was to determine the level of exposure to lead of selected representatives of children's population attended nursery school, aged 2 to 4 years, residing in three different districts of Chorzów as far as the traffic intensity is concerned. It is the most densely populated town in Poland with the high concentration of industry and considerable intensity of traffic. Number 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 mean of the blood lead concentrations were: 131, 132, and 199 micrograms/l and were not statistically valid in their differences. Median ranges were 118, 133 and 144 micrograms/l. Averages above the level 200 micrograms/l were found in the case of 19.5%, 11.8% and 15% children. Data were estimated in comparison with WHO recommended admissible blood lead level in overall population. The obtained data suggest higher lead absorption in the examined children's population.
