In 1997, Philippe Grandjean and collaborators at the Odense University, Denmark, published alarming results found in over 900 children from the Faroe Islands in the North Atlantic: the higher mercury level in umbilical cord blood was, the more deficient was the intellectual performance of children from 6-7 years old. Memory, attention, speech, dexterity and spatial perception were reduced, depending on the level of mercury in the blood cord blood taken at birth. The study in islands Faroe showed that, and when blood mercury level was below safety limit set by the World Health Organization, children had nerve deficiencies.

Apart from volcanic eruptions, the largest source of mercury pollution is represented by plants producing energy based on coal and garbage incinerators. European waters are not less polluting than the american ones. The bacteria convert mercury stored in the oceans and seas to methylmercury, which is embedded easier in the fish bodies.

Space does not permit us to discuss the problem of amalgam dental fillings, but mercury in fish, however, as methyl is far more toxic than the one used by dentists.

In 1999, in Germany, pregnant women and those that breastfed were warned to not consume pike, perch, eel, swordfish and tuna due to their high content of mercury. The predatory fish contain the most toxic substances.

In 2002 Tetsuya Endo and collaborators at the Hokkaido University, Japan, found in the whale liver 1.970 micrograms per gram mercury concentrations . This means almost  5,000 times more than the limit set by the Japanese government – 0.4 micrograms of mercury per meat gram. To these concentrations, an adult weighing 60 kg, consuming only 0.15 g liver, ie the sixth part of a gram, would exceed the level of mercury admitted for a week by the Health World Organization. On average, mercury concentrations in the whale and dolphin liver were 370 micrograms per gram, ie 900 times more than the permissible limits…

US agency for Medicines and Food show that the fish contain much higher amounts of pesticides than fruits, herbs, vegetables and cereals. In the United States every year is used about 600 different pesticides, of total weight of 500 million kilograms. When spread on the grown land, pesticides get into streams, rivers, lakes, seas and oceans. Seas and oceans are polluted also by the debris that flows in, as well as those from ships. Sometimes the waters are so polluted that it is forbidden to bathe in; however, fishing in those waters continues.
