[Lead exposure: risk evaluation for the general Italian population in 1990].
The second Italian campaign for the biological surveillance of the general population against the risk of lead intoxication has been carried out according to the regulations contained in the Presidential Decree DPR 496/82. The investigations of the second campaign--based on the measurement of blood lead levels (PbB)--have been carried out mainly between 1992 and 1996 by various operating centers in some Italian regions. A work group from the Istituto Superiore di Sanità (Italian National Institute of Health) coordinated the activity of the various centers and organised an appropriate quality control program to guarantee the quality of the analytical data collected. A total of 7749 non exposed subjects (4346 females and 3403 males) has been examined, 1170 of which (559 females and 611 males) were under 15 years of age. The median PbB was, for adults, 86 micrograms/l in males and 53.5 micrograms/l in females. As for subjects under the age of 15, PbB levels were 50 micrograms/l and 43 micrograms/l in males and females, respectively. Our investigation confirms the correlation between blood lead levels, wine, and cigarette smoking. The comparison with the results of previous investigations shows a reduction between 40% and 50% of PbB in the general Italian population during the 1985-96 period. It should be pointed out that in certain areas more than 5% of subjects under 15 years of age had PbB exceeding the level (100 micrograms/l) considered safe for avoiding irreversible injury to the central nervous system.
