Abstract A study was conducted into the exposure to atmospheric pollution caused by car traffic by measuring blood lead (PbB) levels in a sample of 657 adult individuals (shopkeepers) all living in Liguria. The mean level of blood lead in all examined individuals was 9.39 µg dl−1 (0.45 µmol per liter; C.I. 95%: 9.06–9.75 µg dl−1; 0.44–0.47 µmol per liter) with a range between 2.0 and 46.03 µg dl−1 (0.10–2.22 µmol per liter). The average Pb values in individuals working in streets with high and very high traffic was 8.30 µg dl−1 (0.40 µmol per liter; C.I. 95%: 7.41–9.31 µg dl−1; 0.36–0.45 µmol per liter) and 9.98 µg dl−1 (0.48 µmol per liter; C.I. 95%: 9.62–10.37 µg dl01; 0.46–0.50 µmol per liter), respectively. These average blood lead levels were statistically greater than the average PbB values of those working in low traffic streets (7.06 µg dl−1; 0.34 µmol per liter; C.I. 95%: 6.22–7.94 µg dl−1; 0.30–0.38 µmol per liter).The percentile distribution (50th, 90th and 98th P) for all subgroups surveyed has always proved to be below the maximum limits specified by EC Directive No. 77/312.
