Abstract
In a survey of the paediatric significance of environmental lead there was evidence that part of the maternal intake of lead may influence the fetus’ (Barltrop, 1969). Lead is incorporated in calcified tissues, and the studies of Altshuller, Halak and Landing (1962) and of Needleman, Tuncay and Shapiro (1972) indicate that the primary teeth provide evidence of lead exposure during infancy, a typical concentration being 10 p.p.m. The measurement of lead in developing teeth of fetuses would indicate uptake during the earliest period.
