Yearly since 1978 we have measured blood lead concentrations (B-Pb) in children living in the municipalities of Landskrona and Trelleborg, in southern Sweden. A substantial decrease of B-Pb was found for the period 1978-2001, as an effect of gradual reduction of petrol lead.1,2 We here present results up to 2006. Altogether, 3646 children, aged 7-12 years, have been studied (different children across all years).
