    Abstract:
    Blood lead levels were assayed in 261 children (133 males and 128 females) living in Campania, 137 (63 females and 74 males) in urban areas and 124 (65 females and 59 males) in rural zones, aged between 0.197 and 16.863 years. Blood lead determination was carried out by electrothermal atomic absorption spectroscopy. All children were interviewed about common risk factors for lead exposure. PbB (median +/- SD) were significantly higher in the urban than in the rural population (6.0 +/- 0.31 vs 3.75 +/- 0.25 micrograms/100 ml; p < 0.001). The frequency of blood lead level above 10 micrograms/100 ml was 4.21% in our tested group, i.e., significantly lower than in previous studies. A significant direct correlation between blood lead levels and age was found (r = 0.47; p < 0.001). In agreement with the literature on this subject, our findings show a significant reduction with time, of blood lead levels of children and adolescents in our region. Time of exposure more than total dose seems to be important for the increase of blood lead level.
