Lead levels in whole blood of an adult population group from Rome.

Pb-blood levels of 801 adult non-occupationally exposed subjects from Rome are reported. The investigation was carried out according to EEC Directive No. 77/312 with acceptable quality control of analytical data. A mean Pb-blood level of 173 micrograms/l (198 micrograms/l for males and 150 micrograms/l for females) was found; good correlations were found between Pb-blood levels and age, sex and smoking habits but no correlation was found in relation to drinking habits, residence and other variables which were examined. In the present survey all the three EEC reference levels were observed.
