Nine paired placenta, maternal blood and umbilical cord blood specimens were collected from women at delivery in Tokyo in 1970. The specimens were analyzed by mercury vapor photometry. Results indicate that the mercury content in the red cells of the umbilical cord blood tended to become higher than that in the maternal red cells with an increase of mercury level in the maternal blood. Though the difference was very small, the mercury content of plasma from umbilical cord blood was significantly lower than that from maternal blood. The mercury content in the placenta was the highest value among the paired specimens. This suggested that mercury accumulated in this organ. The distribution of mercury between cells and plasma was different when maternal and umbilical cord blood were compared. The ratio of mercury content in the red cell to that in the plasma was smaller in the maternal blood than in the umbilical cord blood.
