- The EPA asks pregnant women to limit their consumption
of large fish such as tuna, to once per week. The reason for
this decision is that the high mercury content of the
tissues in some of these fish may damage their fetus.
However, it is safe for them to eat other fish such as
sardines, as often as they like. Explain how different fish
living in the same area can have such variation in the
mercury content of their tissues.
