Comparison of heavy metal concentrations in human umbilical cord in 1980 and 1990.

The well-known Minamata disease was caused by mercury; the Itai-Itai disease by cadmium; and lead poisoning by gasoline additives. Following our previous investigation on heavy metal concentrations in the umbilical cords in 1980, total mercury, cadmium and lead concentrations in the umbilical cords (from 20 males and 20 females) have been measured in 1990 for comparison in the present study. The changes in metal concentrations in 1980 and 1990 were: from 0.007 +/- 0.005 microgram/g to 0.011 +/- 0.008 microgram/g for total mercury; from 0.019 +/- 0.016 microgram/g to 0.006 +/- 0.005 microgram/g, from 0.151 +/- 0.123 microgram/g to 0.046 +/- 0.038 microgram/g for lead. Total mercury accumulated in the umbilical cords increased to approximately 1.6-fold, while cadmium and lead decreased to approximately 1/3-fold during these 10 years.[1]
