Mercury levels on the rise in Hawaiian yellowfin tuna

Mercury concentrations in tuna are increasing by nearly four percent a year, according to a new University of Michigan-led study, which suggests rising atmospheric levels of toxin are to blame.

Researchers came to this conclusion using the findings from three previously published reports, which studied yellowfin tuna caught near Hawaii in 1971, 1998 and 2008. In the studies, scientists tested the tuna’s muscle tissues, finding that nearly all of the mercury they detected was the toxic methylmercury.
