RESUMO
Food samples and ready-made meals from the traditional Italian-type diet were analysed for selenium content. The average Se content varied in food samples from 7 micrograms/kg w/w (fresh fruit) to 226 micrograms/kg w/w (fish). The highest average contents were obtained in the animal products and in legumes. Among ready-made foods the animal derived dishes were the richest in Se, representing 78% of the estimated total daily dietary intake of Se. The average daily dietary intake of selenium for Italian people is estimated to be 50.9 +/- 29.8 micrograms Se/day when results obtained on complete meals are used, while it is 45.0 +/- 30.8 micrograms Se/day when results on foods and statistical data on consumption are used.

Blood lead (PbB) levels were determined in children living in Campania (in Naples and in a rural zone in the district of Caserta). Atmospheric lead (PbA) concentration in these considered areas was monitored for 1 yr (1993-1994). The children tested were questioned about common sources of lead, other than atmospheric, relating to their living and dietary habits. The PbB levels in children living in Naples were, at the 50th percentile, 13.8 micrograms/dl in males and 13.7 micrograms/dl in females; in children living in the rural area the median PbB levels were 8.9 micrograms/dl in males and and 8.8 micrograms/dl in females. The annual mean values of atmospheric lead were 1.15 +/- 0.24 micrograms/m3 in Naples and 0.23 +/- 0.07 micrograms/m3 in the rural area. Significant and congruent mean differences between urban and rural sites were found in children's blood and concurrent air lead. Considering the PbB level of 10 micrograms/dl as the maximum level that is not associated any known adverse effect in children, the Neapolitan group can be considered at risk of chronic intoxication by lead.
