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.

对鹿儿岛县M町252名母亲及其婴儿进行了甲基汞暴露对婴儿生长发育的危险性调查。母亲头发总汞浓度的几何平均值为1.60ppm。母亲头发中总汞含量随母亲哺乳期的延长而降低。根据回归系数计算，母乳喂养一个月可使发汞浓度降低1.065ppm。产犊间隔时间短时，母鼠被毛汞含量高。母乳的泌乳时间较长，导致婴儿开始独立行走的时间较晚。
