March 25, 2024 — French researchers have found that mercury levels in tuna have remained relatively unchanged at a relatively high level over the past five decades.
The researchers’ study, published on 21 February and titled “Stable Tuna Mercury Concentrations since 1971 Illustrate Marine Inertia and the Need for Strong Emission Reductions under the Minamata Convention,” revealed mercury levels in the fish remained nearly the same from samples ranging from 1971 to 2022, according to the New York Times.
