The survey found that 25% of babies' blood and hair contain mercury that exceeds the standard, and 6% of mothers' mercury exceeds the standard  The researchers said that even if the mercury content of fish meets safety standards, if pregnant women eat too much for a long time, mercury will pass through the placenta to the fetus
Due to the poor excretion capacity of the fetus, mercury can easily accumulate in its body, which will affect the development of the baby's brain and cause retardation of intellectual development
Long-term and excessive consumption of fish by pregnant women will affect the baby's brain development.
