We read with great interest the communication by F. J. deCastro and co-workers,1 indicating the influence of air lead on blood lead levels in children.
Azar et al.2 have shown that in taxi drivers there is indeed a correlation between air lead and blood lead levels. Similar results were obtained by Knelson and Bridbord.3
We are carrying out systematic investigations on the significance of lead emission for mother and neonates in the highly industrialized Rhine-Ruhr area.4
