Mercury is toxic to the nervous system particularly during early development

Exposure to mercury, even in small amounts, may cause serious health problems. The fetus, newborns and children are especially susceptible to mercury exposure because of the sensitivity of their developing nervous systems. Large predatory, non-fatty fish (such as shark) can have high levels of mercury. Mercury in the environment is mainly caused by human activity, particularly coal-burning plants.
