Geographical patterns in blood lead in relation to industrial emissions and traffic in Swedish children, 1978-2007
Background: Blood lead concentrations (B-Pb) were measured in 3 879 Swedish school children during the period 1978-2007. The objective was to study the effect of the proximity to lead sources based on the children's home and school location. Methods: The children's home address and school location were geocoded and their proximity to a lead smelter and major roads was calculated using geographical
