AIRBORNE LEAD CONCENTRATIONS IN THE UNITED KINGDOM 1985-1992

Urban, rural and kerbside lead in air concentrations are observed to follow closely estimated emissions of lead from petrol fuelled vehicles. In particular, they reflect the reduction in the lead content of petrol from 0.4 to 0.15 grams/litre in 1986 and the rapid increase in the usage of unleaded fuel since 1988. Overall average lead concentrations at rural, urban and kerbside sites in 1992 were approximately 26% of those in 1985, with the largest reduction (to approximately 22% of 1985 levels) found in kerbside locations and the smallest (to approximately 41%) in rural areas. Concentrations of airborne lead in industrial areas, close to production and metal- handling processes involving this metal, were seen to peak in 1987/8 and decrease thereafter. Annual average concentrations of lead at all UK measurement sites are now well below the EC Directive limit value of 2 micrograms/cu litre and all but 4 sites (in industrial areas) are below the World Health Organisation guideline concentration range of 0.5-1.0 microgram/cu litre.
