However, some types of fish contain a lot higher mercury levels than others. Mercury is dangerous to both natural ecosystems and humans because it is a metal known to be highly toxic, especially due to its neurotoxic ability to damage the central nervous system. Shrimp was the most popular choice (46%), followed by tuna (34%), and salmon (27%).

Most species build up only low levels of mercury over their lives. [53] In 1998 the Convention on Long-Range Transboundary Air Pollution was adopted by most of the European Union, the United States, and Canada. A second example of re-emission is a forest fire; mercury that has been absorbed into plant life is re-released into the atmosphere.
