Nearly 400 people live within 100 metres of the gravelly hill interchange and nearly 4000 within 300 metres. It is the effect of airborne lead on the health of people living near the interchange which prompted this report. Concentrations of lead in air sampled at various sites in the vicinity of gravelly hill have been measured since before the interchange opened. Levels fall with increasing separation from the motorway, though in general the atmospheric lead levels are in no way exceptional for urban areas. A small increase in the mean blood lead levels of people living near the motorway have been detected, but there is no danger of these people developing clinical lead poisoning. There is some suggestion of a seasonal trend in lead levels as a consequence of meteorological factors. A comprehensive survey of lead in dust is at present in progress in birmingham and further work is continuing around gravelly hill. /TRRL/
