Abstract
Hair samples were taken from mothers and newborns. The mean lead value of infants’ head hair was found to be higher than that found in many older children and was suggestive of placental lead transfer. There was a significant correlation between maternal copper in hair and infants’ lead in hair.
As the age of the mother increased the copper levels in the infants’ hair decreased. The mean values of zinc decreased in mothers as parity increased. Mean hair lead values were significantly higher in blacks than in whites. The infants’ hair copper values increased as the parity of the mothers’ increased only in blacks. Zinc and iron content of infants’ hair was higher than mothers’ hair.
There may be a need to screen certain populations during pregnancy so that corrective measures can be taken.
