  1. Lead in the ambient air and blood specimens of children in Helsinki.

    Article - En anglais

    Ambient air lead concentrations have been measured in Helsinki since 1978.

    The mean concentrations at various stations reached maximum values in 1980, being then 209- 1150 ng/m3.

    From 1980 to 1991 the concentrations decreased to one-righth (335-41 ng/m3) at the three stations where measurements were made continuously.

    Concomitantly the estimated annual lead emissions in Helsinki decreased from 78 to 9 tons, mainly owing to the reduced emissions of lead in exhaust gases from road traffic.

    The mean concentration of lead in the blood of children in day-care centres was 46 mug/l in 1983 and 30 mug/l 5 years later.
