LEAD alkyl additives in petrol are combusted and emitted into the ambient atmosphere. Their coarser fractions are responsible for the high concentrations of lead in vegetation near roads1,2. Fine lead aerosols have been shown to travel long distances and be washed out of the atmosphere in polar snows3. In this communication I report studies on lead isotopes in samples of roadside soil and grass.
