Research Abstract

The risk on growth and development for methylmercury exposure to baby was examined by 252 of mothers and their babies at M town in Kagoshima Prefecture. The geometric mean of total mercury concentration of mother's hair was 1.60ppm. The total mercury concentration of mother's hair has decreased as the period of mother's milk giving long. It could be calculated that the hair mercury concentration of 1.065ppm had decreased by suckling mother's milk for one month according to the regression coefficient. When the calving interval is short, he mercury concentration of mother's hair is high. The lactations of mother's milk being longer brought the time of starting walking of the baby by oneself was late.
