Lead levels in Birmingham dust

Dust is important as a factor affecting amenity and there are suggestions that it can make a significant contribution to the exposure of children to toxic materials and particularly to lead. The results are presented of an investigation into the lead concentrations in dust collected in Birmingham. Relationships are shown to exist between samples from similar areas and the distributions of lead concentrations throughout the City are shown. However, interpretations must be made with caution and this is illustrated by referring to some of the problems involved in the collection and chemical analysis of the samples.
