Abstract

The Isotopic Lead Experiment (ILE) was a large-scale field project to assess the contribution of lead in petrol to the total lead in human blood and in air. From 1975-81, the isotopic ratio of 206Pb/207Pb in petrol in the Piedmont region of Italy was varied significantly. The ratio in airborne lead in and around Turin closely followed these variations. The isotopic ratio of blood lead of the inhabitants behaved similarly to a lesser, yet significant, extent. The contribution of local petrol lead to airborne particulate lead is calculated to be about 85% for downtown Turin and 60% for its countryside. The contribution to adult blood lead is about 5.5 microg/dl i.e. about 24%, in Turin, decreasing with increasing distance from the town. This is based on local "labelled" lead only and does not consider possible import of non-labelled petrol lead from other regions, in vehicles, or in food or air masses.
