What is mercurial tuna?



  1. 0 Votes

    Mercurial tuna is tuna found with high levels of mercury in it. It is of scientific concern because tuna is not a shore fish (many fish become contaminated with mercury as a result of waste products from factories and such). Instead, it is an open ocean fish, meaning that mercury contamination in the ocean is spreading dramatically.

    Mercurial tuna is mercury-contaminated tuna. What happens is that mercury is accidentally deposited into water and is then picked up by microorganisms, which convert some of it to “methylmercury,” a highly toxic form that builds up in fish and the animals that eat them.
