    Article - En anglais


    To assess the exposure to toxic metals and to evaluate its possible association with essential elements and socioeconomic status in children from the town of Bytom in the Katowice area ; this area is one of the most polluted industrialized regions in Poland.


    Concentrations of lead, cadmium, mercury, selenium, magnesium, copper, and zinc were determined in whole blood of 211 children aged 9 years.

    Thc samples were analyzed using inductively coupled plasma mass spectrometry (ICP-MS).

    Information on socioeconomic factors was collected using questionnaires.

    Concentrations of trace elements in the blood of 24 Swedish children aged 9 10 years were used for comparisons.


    The concentrations of lead detected in the blood of the Polish children ranged from 11.09 to 1.9 mumol/l, with the median value being 0.27 mumol/l. Statistically significant associations were found between lead and such socioeconomic factors as the number of siblings, trips outside the region, maternal smoking, playing outdoors, and apartment standard.

    The average blood lead level was about 3 times higher in the Polish children than in the Swedish group.

    The median blood concentration of cadmium found in the Polish children was 3.4 nmol/l (range 1.1-41 nmol/l ; almost 3 times higher than that detected in the Swedish children), and that of mercury was 3 nmol/l (range 0.5-11 nmol/l).

    The median blood levels and ranges of the essential elements were 1.1 (0.7-2. (...)
